The reason for slewing bearing teeth broken :
Firstly£®installation reasons
1, the gear adjusting clearance do not meet the requirements when installation, gear mesh cause broken teeth during operation, should strictly adjust the lateral clearance according to the requirement.
2, the pinion runout does not adjust according to requirements , operation, the maximum position runout between small pinion and big pinion meshing stuck caused teeth broken . Adjust the gear and small pinion meshing adjustments, then for trial operation according to the requirement .
3, the size of the gear axis is not parallel, the gear mesh caused teeth broken after installation , should confirm the two gear axis is parallel.
4, slewing bearing installation bolt is not tight, the size of the gear mesh, cause broken teeth, fastenning bolt in accordance with the requirements.
Secondly . application reasons
1, violate the operating procedures, overload and high speed rotation, host machine collide obstructions, etc., should be strictly in accordance with the operation procedures requirements .
2, there is something card into when slewing bearing and pinion meshs, should confirm the gear is clean and check regularly.
