2. Constraints and Requirements
•Gearbox (type, design)
•Material - Acrylic ( Poly(methyl methacrylate) )
•Motor
•Weight to lift
•Height
•Efficiency

3. Concept
Map
Figure 1.
The Concept map

4. Initial Ideas
Conventional Spur Gears
Compact Spur Gearbox
Helical or Herringbone gears
Planetary Gearbox Figure 2A. Spur Gears
Figure 2B. Helical Gears

5. Ideas in response to the project
Design of Gearbox
Pros and cons
Simplicity and effectiveness
Time
Material provided/using

6. Design Chosen
The Planetary
Gear Set
Figure 3.
A basic Planetary Gear arrangement

7. Design Chosen
Reason for our decision
● Much higher density torque reduction
when compared to spur gears.
● Best at retaining lubrication .
● Very Efficient
● Creative approach to the problem.
Figure 4.
Top View of the first iteration of our
design

8. Design Chosen
Our design, requires the 3 shafts
transferring torque from the
planet gears to be lifting the 8kg
weight.
Ran a simulation of statics on
solidworks
Largest stress was much
lower than the yield stress

SolidWorks load simulation test

9. Design Chosen
Mounting the planetary gear box
The ring gear will extend out and
allow us to mount the gearbox
through it as well as the outside
housing
this will stabilize the system
Force from the the weight will create
a moment into the mounting block

gearbox

10. Now what?
Refine the Design
Beginning the build
The Gadget test
Do the tests
