Scrapped or repaired standard open or low speed gear, the gear should be scrapped when the amount of wear exceeds 30% of the pitch circle tooth thickness; the gear should be discarded when the wear rate of medium speed drive gear exceeds 20% of the tooth thickness; Carburizing gear, if carburized layer wear up to 80% or carburized layer cracks, the gear should be scrapped. When the gear wear does not exceed the above provisions, can take a variety of do
