Design Chosen

The Planetary Gear Set

Figure 3.A basic Planetary Gear arrangement

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

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

Figure 5.SolidWorks load simulation test

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
