6-11. Inspection of the gears
When checking the reduction gear, please check the lubrication by oil or grease, teeth contact, meshing state etc.
visually in addition to measuring the wear amount of both the gears. Please refer to 'Table 1' and 'Table 2' for the
wear limit.
Table 1: Gear wear criteria
Wear limit
Gear
1st stage pinion,
1st stage gear
5% or less of the full thickness tooth thickness on the pitch circle
Others
Not more than 10% of the original tooth thickness on the pitch circle
Coupling part (shaft, hole)
