Belt drives use belts looped over pulleys to mechanically link rotating shafts and transmit power between them. Common types include flat, round, V-belt, multi-groove, and timing belts. Belt drives are simple, economical, allow for shaft misalignment, absorb shock, and can transmit power over long distances. However, they have speed and power limits and require adjustment over time for belt stretch.

DESIGN ANALYSIS OF UNIVERSAL JOINT SHAFT FOR ROLLING MILLSSughosh Deshmukh
The properties of steels made by rolling of billets
are mainly dependent on the process of forming. The
performance of the rolling mill depends on the Universal
joint shaft through which the power is transmitted to the
rollers of a mill. This report mainly focuses on the
analysis of universal joint shaft for rolling mills because this
shaft is subjected to vibrations caused due to the jerk
produced during the passing of billet through the rollers.
INTRODUCTION

• It is universally applicable, i.e. any material can be spun to any required count
• It delivers a material with optimum characteristics, especially with regard to structure and strength.
• It is simple and easy to master
• The know-how is well established and accessible for everyone
The main sources of power for agricultural machines, i.e., the diesel engine for self-propelled machines and the electrical motor for many stationary machines used on the farmstead.
Pull-type machines must receive propulsion and rotary power from the tractor.
Power is transmitted from the tractor to the machine by means of traction, power-take-off drives (PTO), and/or by fluid power.
Rotary power is also transmitted by means of belts and chains.
Topics related to rotary power transmission are presented here.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

2. INTRODUCTION
A belt is a looped strip of flexible material, used
to mechanically link two or more rotating
shafts.
They may be used as a source of motion, to
efficiently transmit power, or to track relative
movement. Belts are looped over pulleys.
In a two pulley system, the belt can either drive
the pulleys in the same direction, or the belt
may be crossed, so that the direction of the
shafts is opposite.
3. OVERVIEW WHY USED?
Transfer power (torque) from one location to
another. From driver: motor,peddles,
engine,windmill,turbine to driven: conveyor
belt, back wheels/bike,generator rock
crusher,dryer.
Used to span large distances or need flexible
x-mission elements. Gear drives have a
higher torque capability but not flexible or
cheap.
Often used as torque increaser (speed
reducer), max speed ratio: 3.5:1. Gear
drives?? Virtually unlimited!
4. BELT DRIVE
ARRANGEMENTS
Machines operated by belt drives must have an idler, an
adjustable base, or both
Idler is use to help maintain constant tension on the belt
Slack side: top side of belt in horizontal arrangement
Tight side: bottom side of belt in horizontal arrangement
Inside idler pulley is placed near the driver on the slack
side or on the tight side near the driven pulley
Idler pulley should be same diameter or larger than the
driver
Outside idler pulley is placed near the driver on the
outside of the belt on the slack side or on the tight side
near the driven pulley
Idler pulley should be slightly larger than the driver pulley
6. FLAT BELT DRIVE
Flat belts for power transmission Flat belts:
Advantages-Simple construction Low cost High
flexibility High tolerance to overload Good
resistance in abrasive environments
Disadvantages-Noisy Sliding is possible Low
efficiency at low speeds Tensioning is required
But these drives are bulky, requiring high tension
leading to high loads, and are poorly suited to
close-centers applications.
Flat belts were traditionally made of leather or
fabric. Today some are made of rubber or
polymers. Grip of leather belts is often better if
they are assembled with the hair side (outer side)
of the leather against the pulley
7. USES/ADVANTAGES
where high-speed applications (up to 140,000
rpm) are more important than power
transmission
long center distances are necessary
where drives with non-parallel shafts are
required (belt can be twisted)
applications requiring small pulley diameters
(as small as 3/8")
8. DISADVANTAGE
tend to slip under load
lower efficiency at moderate speeds
must be kept under tension to function (require
tensioning devices); causes high bearing loads
require friction for proper functioning
(therefore, cannot be used when absolute
synchronization between pulleys must be
maintained)
stretch over time
10. ROUND BELT DRIVE
Round belts are a circular cross section belt
designed to run in a pulley with a 60 degree V-
groove.
Round grooves are only suitable for idler
pulleys that guide the belt, or when (soft) O-
ring type belts are used.
Early sewing machine utilized a leather belt,
joined either by a metal staple or glued, to
great effect.
12. VEE BELT DRIVE
They provide the best combination of traction,
speed of movement, load of the bearings, and long
service life.
. The "V" shape of the belt tracks in a mating
groove in the Pulley (or sheave), with the result
that the belt cannot slip off. The belt also tends to
wedge into the groove as the load increases—the
greater the load, the greater the wedging action
improving torque transmission and making the V-
belt an effective solution, needing less width and
tension than flat belts. V-belts trump flat belts with
their small center distances and high reduction
ratios.
13. USES/ADVANTAGES
Useful in automotive, household, industrial, and
agricultural applications
easy to install and replace
low maintenance
provide shock absorption between driver and driven
shafts
best at speeds between 1500 to 6500 feet per minute
(with 4500 fpm peak capacity, or ideal speed)
useful with temperature range of –30 F to 180 F
are 90-98% efficient
maximum satisfactory speed ratio is approximately 6:1
14. DISADVANTAGE
improper belt tension can reduce service life
belt life at increased temperatures (above 180
F) is significantly shorted
require friction for proper functioning
16. MULTI GROOVE BELT DRIVE
A multi-groove or polygroove belt is made up of
usually 5 or 6 "V" shapes alongside each other.
This gives a thinner belt for the same drive surface
offers an improved efficiency, as less energy is
wasted in the internal friction of continually
bending the belt.
this gain of efficiency causes a reduced heating
effect on the belt and a cooler-running belt lasts
longer in service.
18. TIMING BELT DRIVE
Timing belt are a positive transfer belt and can
track relative movement.
These belts have teeth that fit into a matching
toothed pulley. When correctly tensioned, they
have no slippage, run at constant speed, and
are often used to transfer direct motion for
indexing or timing purposes.
Timing belts need the least tension of all belts,
and are among the most efficient.
19. USES/ADVANTAGES
useful in operations requiring high efficiency,
timing or constant velocity
no slippage (more positive power
transmission)
will not stretch
required belt tension is very low
speed is transmitted uniformly
22. ADVANTAGES OF BELT DRIVE
They are simple. They are economical.
Parallel shafts are not required.
Overload and jam protection are provided.
Noise and vibration are damped out. Machinery
life is prolonged because load fluctuations are
cushioned (shock-absorbed).
They are lubrication-free. They require only low
maintenance.
They are highly efficient (90–98%, usually 95%).
Some misalignment is tolerable.
They are very economical when shafts are
separated by large distances.
23. Up to 95% efficient
Designed to slip when an overload occurs
Resist abrasion
Require no lubrication (no metal to metal
contact)
Smooth running
Quiet
Can transmit motion and power over long
distances
24. Operate effectively at high speeds
Flexible shaft center distances
Inexpensive (when compared to other drive
systems such as chain or gear drives)
Easy to assemble and install
Have flexible tolerances
Absorb shock well
Easy and inexpensive to maintain
25. DISADVANTAGES OF BELT
DRIVE
The angular-velocity ratio is not necessarily
constant or equal to the ratio of pulley diameters,
because of belt slip and stretch.
Heat buildup occurs. Speed is limited to usually
7000 feet per minute (35 meters per second).
Power transmission is limited to 370 kilowatts (500
horsepower).
Operating temperatures are usually restricted to –
31 to 185°F (–35 to 85°C).
Some adjustment of center distance or use of an
idler pulley is necessary for wear and stretch
compensation.
A means of disassembly must be provided to
install endless belts.
