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

This phenomenon mainly occurs in pinion equipment with gear quenching, which involves the following aspects:


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

·Center way away error

Manufacturing tolerances throughout gear machining, especially frequency errors, cannot be avoided, which can have an adverse impact when combined by using bending effects.

·Drive component

Most slewing drive units are mounted in a cantilevered arrangement and the deflection in the pinion shaft is unavoidable. High force will all together produce elastic deformation in the interface of the slewing get and mounting structure. This deformation can also cause meshing problems.


The three influencing factors mentioned will bring about high peak loads acting to the edge of the pinion tip, which may cause this lubricant film to rupture and direct metal contact will increase the chipping effect.

Xuzhou Wanda Slewing Displaying Co.,Ltd. is a professional manufacturer and exporter connected with slewing bearing, which are mainly applied in vent machinery, mining machinery, welding devices, construction vehicles, modular motor vehicles and small wind electric power systems etc. Slewing having can bear axial push, radial force and tilting minute. The diameter range of slewing bearing you can easliy provide can be via 200 mm to 5000 mm.
