Determination of the limit deviation of gear tooth thickness

The determination of the limit deviation of gear tooth thickness is explained as follows for reference.

Determine a pairgearThe total amount of thinning in the normal backlash.

1. Ensure the minimum backlash necessary for normal lubrication.

2. The minimum backlash required to compensate for deformation caused by temperature rise.

3. The total amount of tooth thickness reduction of the two gears required to compensate for machining errors and installation errors.

4. Determine the upper and lower deviation of the tooth thickness.
