Selection of gear pair backlash (for reference)

The selection of gear pair backlash is for reference.

1. Backlash of gear pairgearThe working conditions are determined and have nothing to do with the precision grade of the gear.

2. The size of the backlash is mainly determined by the tooth thickness and center distance.

3. "Base center distance system"-in the case of a fixed center distance limit deviation, different minimum backlash can be obtained by changing the tooth thickness deviation.
