which can have a negative impact when combined together

In the actual technique slewing bearing and the pinion, problems often occur, resulting in wear, chipping, and abnormal noise around the tooth root or side with the gear, as shown while in the following figure.

This happening mainly occurs in pinion gears with gear quenching, , involving the following aspects:


In high-force applications, dynamic weight peaks under acceleration, braking action or vibration may cause elastic deformation in this meshing teeth.

·Center length error

Manufacturing tolerances in gear machining, especially frequency errors, cannot be prevented, which can have a negative impact when combined together with bending effects.

·Drive unit

Most slewing drive units are mounted within a cantilevered arrangement and the deflection from the pinion shaft is inescapable. High force will concurrently produce elastic deformation at the interface of the slewing travel and mounting structure. This deformation may also cause meshing problems.


The three influencing factors mentioned will provide high peak loads acting about the edge of the pinion suggestion, which may cause this lubricant film to rupture plus direct metal contact increases the chipping effect.

Xuzhou Wanda Slewing Bearing Co.,Ltd. is a reliable manufacturer and exporter of slewing bearing, which are mainly applied in vent machinery, mining machinery, welding equipment, construction vehicles, modular vehicles and small wind power systems etc. Slewing bearing can bear axial push, radial force and tilting point in time. The diameter range of slewing bearing we are able to provide can be from 200 mm to 5000 mm. slewing bearing
