Gear clearance inspection standards

2019-03-18 18:38:26
There are gear clearance inspection standard,and suitable for many geared motor,such as 12v geared motor.
1. The clearance of the gear meshing teeth is generally not more than 0.20 mm. If the meshing tooth wear has exceeded the range, the gear should be replaced. Secondly, it should be checked whether the wear of the bushing affects the increase of the lateral clearance of the gear.
2. The clearance between the end of the gear and the cover of the housing should generally be in the range of 0.08 to 0.010mm.
3. The clearance between the gear shaft and the bushing should generally be within 0.03 to 0.05 mm. If the bushing is excessively worn, the center distance of the two gears will increase, which will inevitably lead to an increase in the inclination of the radial clearance. Therefore, the wear of the bushing must exceed the range of wear.
4. Also pay attention to the clearance between the tooth tip of the gear and the pump casing.
