What does the back of the reducer mean? How is it calculated?,Can it be understood that the backlash is 2 times the gear gap, or approximately 2 times?
Servo motors are generally used reducer, such as Sumitomo's FC series cycloid reducer, IB series of planetary reducer
There is a small angular displacement at the input end of the reducer. This angular displacement is the clearance of the return stroke. The unit is "divided", which is 1/60 of the time
The backlash is also called the return clearance. The domestic definition is generally: the output terminal is fixed, the input end rotates clockwise and counterclockwise, so that the input end has a rated torque +-2% torque
