3. 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.
5.
6. Planetary Gear
Positives
• Converts high speed low torque to low speed high
torque
• Compact
Negatives
• Complicated
• Needs extra support for wind up rods
• Weight may affect orbit
7. Straight line gear train
Positives
• Gradually increases torque
• Simple
Negatives
• Large
8. 4 Part gear train
Positives
• Mix of speed components and torque components
• Compact
• Load not as concentrated as other designs
Negatives
• Complex
