Project Summary
The intent of this project was to design a gearbox containing
two shafts, one
coupling, four bearings and two helical gears. The gearbox is
part of a system to
test the idling characteristics of an automotive timing drive
system. The gearbox is
being powered by a 5 hp, 60Hz AC, electric motor with a speed
of 1725 rev/min.
The goal of the gearbox is to produce a 2:1 speed reduction to
862.5 rev/min
using helical gears.

5. There were four important machine specifications that the
gearbox had to
abide by. First, the coupling combining the motor and first shaft
transmits torque
but does not add to the bending or shear aspects of the system.
The next
specification was that the entire system is to be bolted to a
horizontal bedplate but
is only accessible from the top surface. In regards to the
machine components
(apart from bolts and bearings), they must all be designed with
a factor of safety
between 1.5 and 2.0 with respect to infinite life. The bearings
must achieve a life
of at least 200,000,000 cycles and the factor of safety of the
bolts must be greater
than 1.5.
Proposed Design

Figure 2: Exploded view of proposed design
Device operation description
This device was designed to perform in the following manner.
The motor is
connected to the first shaft via a coupling with set screws and
specifically designed
keys. It will turn the shaft smoothly at 1725 rpm as it is
supported by two ball
bearings appropriately spaced to provide acceptable moments
and deflections. On
the end of the first shaft is a pinion gear attached with a key and
pin. The pinion
gear, complete with 12 teeth, interferes with the second helical
gear with 24 teeth,
respectively. This ratio of teeth provides the ideal speed
reduction to 862.5 rpm.
The new speed is then transferred to the second shaft that is
also support by two

7. appropriately spaced ball bearings.
Analysis Summary
When analyzing this system, many assumptions were made in
order to
design the components. The helical pinion and gears were
designed to a pressure
angle of 20˚, a helix angle of 30˚, and a diametral pitch of 14
teeth/in. The
chosen material was grade 1 steel with a hardness, Hb of 200
with a quality of 6
and a reliability of 0.9. The shafts were designed to be made out
of 1020 CD steel.

Also, the coupling weight and gear weight were ignored when
analyzing the shear
and bending of the shaft for they would be negligible. The
bearings were all
constructed out of steel and the housings are cast iron. The
bearings achieve
infinite life because the maximum load and maximum rpm
values of the bearing
were higher than what would be experienced in this system. The
keys were all

9. constructed from an aluminum alloy with a yield strength of 4.5
kpsi. The height
and width of the key were determined base on the diameter of
the shaft. The
proposed key depth was then chosen from this information. The
coupling was
assumed to achieve infinite life because the key was designed
properly to support
the torque provided by the motor.

Table 2: Safety Factor and Infinite Life Factor Results
The above table shows the results for the safety factor and
infinite life factor for
each design component in the gearbox. All machine components
other than the
bearings and bolt were designed for infinite life. Each
component’s factor of safety

11. 5
falls within reason of the given 1.5 to 2 range. The designed
components
dimensions are realistic and could be manufactured if this
system were to be
constructed.
Summary and Conclusions
Design Limitations
One design limitation was trying to find a coupling that could
fit the 30mm
diameter of the motor shaft as well as the diameter of shaft 1.
Another limitation
was that the gears had to be helical and abide the given speed
reduction ratio. The
motor for the system operated as a specific speed which only
provided a certain
amount of power to the system. Designing all the components to
have a factor of
safety within the 1.5 to 2 range was also constraining.

12. Improvements
There are some improvements that can be made to the system
for it to run
more effectively. One improvement would be to increase the
available horsepower
that the motor outputs. Another improvement could be to look
into using other
types of gears besides helical. In regards to our budget, some of
the materials
were high in price. Looking into other metals for the shaft or
different types of
bearings could lower the cost of the system. Using a different
material could also
aid in the improvement of performance and allow the gearbox to
run more
effectively.

Speed Reducer Gearbox
Design of Machine Elements

21. Project Summery
Design of Small Speed Reducer:
Abstract:
Speed reducers are mechanical gadgets which are utilized for
two purposes. Those elementary utilize is on increase the
measure for torque created toward a enter energy wellspring
with expand the measure from claiming usable worth of effort.
They additionally diminish the information control wellspring
pace to attain fancied yield speeds. The Choice What's more
integrative for speed reducers entails substantially more than
essentially picking you quit offering on that one crazy of an
inventory. By and large those greatest torque, speeds, and spiral
loads distributed can't be utilized all the while. Correct
administration elements must make connected should suit an
extensive variety of dynamic provisions. And, when the suitable
velocity reducer is selected, best possible establishment Also
upkeep are those keys should expanding existence.
Pace reducer classifications. The totally mixture of mechanical
speed lessening units incorporates pulleys, sprockets, gears,
Furthermore rubbing drives. There need aid additionally
electrical items that could progress those engine speed. This
talk will concentrate on enclosed-drive speed reducers,
otherwise called rigging drives Also gearboxes, which need two
principle configurations: in-line and right edge. Each camwood
a chance to be attained utilizing diverse sorts about adapting.
In-line models would ordinarily committed up from claiming

22. helical or goad gears, planetary gears, cycloidal mechanisms, or
symphonious wave generators. Planetary outlines by give
acceptable the most elevated torque in the littlest one bundle.
Cycloidal and symphonious drives the table conservative
outlines on higher ratios, same time helical What's more goad
reducers are by those practically prudent. Constantly on would
equitably productive.
Right edge outlines would commonly made with worm adapting
alternately angle gearing, if mixture drives would likewise
accessible. Worm gears need aid maybe those the majority cost-
effective decrease solution, yet all the typically have a least 3.
15:1 proportion and lose significant effectiveness concerning
illustration proportions try higher. Angle reducers would
exceptionally productive in any case bring a successful speed
diminishment upper point of confinement for 6:1. The sort for
provision dictates which pace reducer outline will best fulfill
the necessities.
In front of picking whatever reducer, determinations must make
gathered should appropriately span Also introduce the unit:
torque, speed, horsepower, reducer efficiency, administration
factor, mounting position, association variables, and
Furthermore term required. Previously, exactly provisions the
measure from claiming backlash, transmission error, torsional
rigidity, and minute of latency need aid likewise imperative.
Torque, speed, strength relationship: The measure of torque
necessary is maybe those mossy cup oak essential criteria,
Likewise this interprets of the sum from claiming fill in those
velocity reducer must perform. In spite of the fact that
previously, basic requisitions figuring out the torque might a
chance to be generally straightforward, it could be challenging
for perplexing hardware. Inertia, friction, Furthermore gravity –
those physical phenomena that tend with oppose movement –
must a chance to be distinguished so that sufficient torque
camwood a chance to be created on succeed them.
Acknowledging coefficients from claiming rubbing and the
acceleration and deceleration about inertial Massenet may be

23. critical at ascertaining required torque. A more point by point
exchange of these components might be found in the
Machinery’s Handbook, movement framework plan Handbook,
What's more different machine configuration publications.
An alternate route previously, finding an existing machine’s
obliged torque will be on take amperage readings starting with
the engine Eventually Tom's perusing identikit those current
draw. Afterward calculations might a chance to be committed on
Figure the required strength. Finally, toward utilizing a standard
torque equation What's more acknowledging those Different
ratios, the intimacy torque quality camwood a chance to be
understood.
When those needed energy will be identified, the administration
factor, must make viewed as will legitimately span those unit.
Those administration element takes under record different
operational parameters, including period about fill in days,
numbers from claiming begins what’s more stops, load
characteristics, Also control sources. The majority reducers
would rate for a greatest torque at a provided for amount from
claiming lifetime hours. The restricting calculate in these
appraisals will be not those gear or shaft strength, yet the
bearing an aggregation. A direct result bearings must backing
the division drives of the gears under load, stacking under those
most extreme rating expands gearbox existence. Conversely, by
expanding the load variables Likewise highlighted above, a
diminish for gearbox term will aftereffect. Therefore, to land at
those powerful torque requirement, the proper administration
Components have will make connected.
Toward this phase the pace reducer Furthermore engine could a
chance to be chose. Commonly a fundamental energy hotspot
for example, an engine alternately motor need been selected,
which works at a particular speed. Arriving In the right speed
reducer proportion and the coming about torque duplication may
be just a matter about isolating the engine pace Eventually
Tom's perusing those driven component pace. Then, the correct
engine measure camwood make found Eventually Tom's

24. perusing plugging in the Different Components Furthermore
qualities to a standard strength recipe.
Coordination pace reducers:
Then afterward selection, the following issue may be how the
gearbox will make incorporated under the machine. Those
fundamental worries would how those gearbox will be mounted
what's more entryway it will be associated with the driver and
determined load.
Shaft introduction is a standout amongst those to begin with
considerations. Over huge numbers requisitions it is alluring
will need possibly those enter or yield shaft vertically situated.
In this circumstance extraordinary consideration must a chance
to be taken will guarantee best possible oil. The oil or grease
clinched alongside a gearbox doesn't main furnish insurance
against rigging wear, as well as to lessening bearing wear. So,
at a standout amongst those shafts is mounted vertically, the
highest backing bearing might not get the oil it needs. Done
specific gearbox plans those sprinkle Furthermore misting made
toward the gears pivoting through those oil supply are sufficient
to give the legitimate lubrication, be that as done low-speed
sorts it will be vital to introduce progressed, fixed bearings.
Clinched alongside at present different high-sounding
provisions it might make vital should give acceptable interior or
outer pumps to convey the oil of the fitting area. At whatever
point a shaft necessities on a chance to be vertically mounted, it
may be essential will figure out whether a substitute oil strategy
will be fundamental.
The following attention is how the pace reducer will be
associated with those force wellspring and of the determined
load. Choices incorporate driving with a pulley, sprocket, or
gear, interfacing for a coupling, accordance shaft, or widespread
joint, Furthermore shaft mounting specifically on the
determined shaft.
The point when interfacing with a pulley, sprocket, or gear, the
fundamental issue is spiral load, usually known as overhang
load. Shaft bearings would not just planned to help rigging

25. division powers Anyway with suit and specific amount from
claiming spiral What's more push stacking on the shafts
themselves. When crashing for pulleys Furthermore sprockets, a
spiral power happens concerning illustration those cinch or
chain tries on turn the shaft. The extent about this compel could
a chance to be computed Likewise the torque transmitted
separated toward the span of the pulley alternately sprocket.
This normally isn’t the main side compel exerted, however?
Those pulley or chain may be tight on the driving side, be that
as need a few slack on the again side. To decrease those coming
about commotion Also forestall cinch slip or tooth rot jumps, it
is basic should introduce a pressure gadget. The point when
those cinch or chain is tightened, extra spiral stacking happens.
The blending about spiral load because of torque Furthermore
strain must be viewed as at selecting a gear drive.
When interfacing a velocity reducer with a coupling, and on An
Lesseps extent, offering shafts Also u-joints, arrangement is the
fundamental worry. Due to machining tolerances on gearbox
lodgings Furthermore mounting plates, adaptable couplings
would recommended. Without accurate alignment, utilizing an
inflexible coupling Might make over the top side loads on the
shaft bearings. Actually with adaptable couplings best possible
arrangement is necessary, similarly as practically couplings will
just permit parallel misalignments of 0. 005 with 0. 010 over.
Also precise misalignments about 1 should 3°. Large portions
coupling plans are suitable for separate applications, in any case
for greatest reducer life, those coupling ought to further
bolstering suit of reinforcement those vocation.
The third alternative for interfacing the gearbox will be on
mount it straightforwardly on the determined shaft for an empty
exhaust yield shaft. This diminishes the worries viewing
arrangement Furthermore spiral loads What's more rations
space. A backing arm starting with those gearbox of the
machine outline keeps the gearbox starting with pivoting
regarding those shaft.
A lot of people gearbox plans consider those engine on make

26. specifically mounted of the reducer. These outlines fuse
whichever greatly exact flanges with permit the engine on make
specifically stopped under those reducer or other adapters for
essential analytics couplings. This dispenses with the
requirement to separate mounting of the motor, be that may be
generally main useful for more modest motors.
In spite of this completes those real considerations for pace
reducer Choice Also mix under those machine, different
components are paramount in certain requisitions. For instance,
for reversing or irregular load applications, the measure about
kickback ought to be lessened. Those second component that
ought a chance to be viewed as is transmission error, or those
positional difference about yield movement relative on
information movement. This will be generally a work for gear
also gathering personal satisfaction What's more is essential at
exact also predictable movement will be obliged. Those third
outline component may be torsional rigidity, which is a
reducer’s imperviousness with turn under load. This is a
particularly significant thought when exact movement must be
supported throughout acceleration and deceleration. The last
plan component will be minute of latency. Previously, quick
acceleration applications, for example, such that servo systems,
the gearbox dormancy expands those engine torque obliged will
move the load. Everyone from claiming these pace reducer
components might be supplied over fluctuating levels for
precision or solidness for expanding expense for that's only the
tip of the iceberg stringent necessities.
Support and disappointment analysis: Despite well-engineered
outlines Also powerful Choice analysis, velocity reducers need
aid subject should wear Furthermore consequent
disappointment. To expand life, correct support methods ought
to make made. The practically critical component may be those
schedule oil change. Oil Furthermore grease particles break
down under those amazing weight of mating gear teethe under
load. The shearing impact from claiming gears cutting through
those oil Also helter smelter temperatures inside those box

27. likewise help oil breakdown. At oil furthermore grease lose
their lubricating properties, reducer wear quickly takes after.
In spite of a specific amount from claiming disappointments
could make attributed with issues for materials alternately
workmanship, as a rule operating states alternately provision
flow need aid on be faulted the point when a pace reducer falls
flat prematurely. At over-burden makes failure, it will be as a
rule as a result those unique outline criteria need changed, the
legitimate administration elements were not applied, the oil
might have been not changed, and alternately there might have
been a major stun load. When bearings come up short it is as a
rule those result about abundance overhand load, shaft
misalignment, alternately a lot of heat. At seals fail, it is well
on the way on something originated the middle of those seal and
shaft, or in view they were painted, dried out, Also got to be
fragile.
Cost-cutting tips. At a chosen speed reducer alternately drive
bundle is exactly a really unreasonable to those provision
parameters, an alternate methodology ought to a chance to be
viewed as. A direct result every one velocity reducer sorts come
in an assortment of nature levels, it ought to further bolstering
be resolved what amount of gearbox will be truly necessary.
However, you normally get the thing that you pay for. There
would a few other “tricks” that could be actualized should shave
costochondritis.
Particular case will be will Think as of evolving those mating
drive segments. In spite of the fact that practically pace
reducers might handle higher torque at more level speeds, those
association will be not straight. As opposed to attempting
should get a whole pace decrease out of the gearbox
Furthermore thusly the whole torque multiplication, a more
diminutive reducer might a chance to be chosen Toward getting
some of the proportion and torque starting with lesquerella
exorbitant pulleys alternately gears. To example, As opposed to
picking a 10:1 speed reducer driving An 1:1 belt, select An 5:1
reducer crashing An 2:1 cinch. Those gearbox best need should

28. would half the fill in.
When from the get go it appears to be that a bigger reducer may
be required with handle abundance overhang load, Think as of
evolving the pulley size. Spiral constrains might make lessened
clinched alongside regulate extent should expands in pulley,
sprocket, alternately rigging diameters. The point when
accelerating and decelerating inertial loads, those torque
required will be Additionally over regulate extent of the time
needed to accomplish the wanted speeds. Adjusting those
acceleration profiles camwood prompt decreased torque
prerequisites. As opposed to measuring reducers will handle
every one torque coming about because of estops alternately
machine jams, introduce brakes to aid in deceleration and
torque limiters on ensure against amazing shocks. Investment
funds dependent upon half might a chance to be figured it out.
Exactly engine Producers offer outlines that furnish full torque
on 2000 rpm. Eventually Tom's perusing multiplying the
reducer ratio, the same yield torque Furthermore velocity might
a chance to be attained for a lesquerella unreasonable engine.
Bringing down working costs might additionally decrease
expenses. When helter smelter speeds are required, Think as of
oil coursing library frameworks alternately outer cooling
choices. In spite of the fact that at first a greater amount
unreasonable upkeep and down run through will be lessened
Also gearbox existence will a chance to be broadened.
Utilization higher effectiveness speed reducers:
To example, select a helical alternately worm plan as opposed
to a standard worm reducer. In spite of the fact that those unit
might cosset 20 on 30 percent more, the helter smelter
effectiveness might consider a littler engine What's more bring
about lesquerella force utilization to payback on best a couple
months.

Calculations and Formula: To find the output torque and speed
of a gear reducer, use these
gear ratio formulas:
Output Torque = Input Torque x Ratio of Gear Reduction
Torque is measured in Inch Pounds
Output Speed = Input Speed / Ratio of Gear Reduction
Data Given:
A gear reducer with 1000 in/lbs. of input torque, an input
speed of 2000 RPM, and a reduction ratio of 3.5:1 is:
1kW=737.56 in/lbs.
Output Torque = 1000 x 3.5
Output RPM = 2000 / 3.5

30. Calculated out this gives an output torque of 3,500 in/lbs. and
an
output speed of 571.4286 RPM. (Rounded to the nearest
10,000th)

reducer configuration issue. However, various break focuses
need aid used in the linearization transform to arriving at an
estimated worldwide result with An low error, What's more a
significant part time is obliged on take care of those
reformulated model. Therefore, this contemplate likewise adopts
the go decrease strategy with upgrade the computational
effectiveness. Compared with metaheuristic methods, this
contemplate ensures the worldwide optimality of the result.
Compared for different deterministic methods, this contemplate
obtains an exceptional result for an easier slip clinched
alongside demand.
