What are the common faults in the gearbox?
Jan 21, 2019

Due to manufacturing errors, improper assembly, or use under improper conditions (such as load, lubrication, etc.), damages such as damage often occur, and four types are common:

(1) Fracture of teeth: fatigue fracture and overload fracture

Fatigue fracture: Usually, the crack is generated from the root of the force side, and gradually develops to the tooth end to break.

Excessive load fracture: due to sudden changes in rotational speed, shafting resonance, bearing damage, shaft bending, etc., the gear is caused to have an abnormal end contact, and the load is concentrated to one end of the tooth surface.

(2) Wear of teeth: due to metal particles, dirt, dust and sand entering the gears, the material wears and the partial welding of the tooth surface tears.

(3) Tooth surface fatigue: Since the tooth surface contact stress exceeds the allowable fatigue limit of the material, the surface layer first produces fine cracks, and then the small pieces peel off until the entire tooth breaks.

(4) Tooth profile deformation: such as crushing, wrinkling
