Planetary gear is an outer gear
that revolves around a central sun gear. Planetary gears can produce
different gear ratios depending on which gear is used as the input,
which one is used as the output.
Materials Used
The gears can be constructed from a variety of materials including :
- Stainless steel
- Hardened steel
- Cast iron
- Aluminum
The gears are suitable for reduction of high RPM electric motors
for use in high-torque low RPM applications. These gears are used in
precision instruments because of their reliability and accuracy.
Use of Planetary Gears
These gears are the most widely used gears having diverse applications
including :
- Sugar industry
- Power industry
- Wind turbines
- Marine industry
- Agriculture industry
