Gear processing parameters: what is backlash?

common problem:What is backlash?

Reply:Backlash is a necessary parameter for gear meshing and smooth operation, the gap between tooth surfaces when a pair of gears mesh.The size of the center distance has an effect on the backlash.The greater the center distance, the greater the backlash.The size of the shaft angle is an important factor that has an important influence on gear tooth contact and backlash.

The assembly distance is an important dimension that affects gear tooth contact and backlash.In order to obtain proper backlash and gear tooth contact, the tolerance should be as close to 0 as possible.If you have more questions or related processing requirements, please consult EP free of charge.
