Design Considerations

• Overall size• Stress• Speed and Torque• Practicality

Looking at the motor provided we straight away identified that it has a high rpm and a low torque, This straight away tells us were going to have to design the gear ratios to be able to manipulate the output and generate enough torque to lift the 10kg weight

4 Part gear trainPositives• Mix of speed components and torque

components• Compact• Load not as concentrated as other designsNegatives• Complex

Planetary Gear

Positives• Converts high speed low torque to low

speed high torque• CompactNegatives• Complicated• Needs extra support for wind up rods• Weight may affect orbit

Straight line gear train

Positives• Gradually increases torque• SimpleNegatives• Large
