Gearboxes: Basic Functions
Gearboxes can provide 3 basic functions:
Change torque and speed |
Change axis of motion |
Convert rotary to straight line motion |
Major application of gears is to change the motor high speed / low torque to low speed / high torque usually required by applications.
High Speed / Low Torque |
Low Speed / High Torque |
Torque Tgear = Tmot • ratio • η (η …gear efficiency)
Speed ngear = nmot / ratio
