① The tooth surface wear, scuffing, pitting corrosion, wear deviation and wear (especially the small gear is easy to wear) of the rolling machine gear cause the vibration of the reducer.
Treatment: replace the seriously worn gear in time. Generally, the reverse operation method can be used to solve the problem of serious tooth gluing.
② The poor contact and uneven force of the meshing surface of each gear make the axial movement of the gear frequent, the tooth fracture or ring gear fracture, and the spoke crack occur, which cause the vibration of the reducer.
Treatment: replace the damaged parts; Adjust the gear ring and spoke door; Replace the gear whose tooth surface wear exceeds the limit; Adjust the bearing clearance; Improve gear lubrication, etc.
③ The sliding key of high-speed shaft and Ting speed shaft is worn, and the connecting bolt of pinion on the shaft is loose or broken, which causes the vibration of reducer.
Treatment: replace the sliding key and broken bolt, and tighten the loose bolt.
④ Rough gear processing and shaft and bearing wear, in the normal operation of the ring gear non working face force, resulting in reducer vibration.
