In the actual technique

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




This sensation mainly occurs in pinion gears with gear quenching, that involves the following aspects:



·bending

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

·Center range error

Manufacturing tolerances within gear machining, especially frequency errors, cannot be avoided, which can have a poor impact when combined by using bending effects.

·Drive system

Most slewing drive units are mounted in a very cantilevered arrangement and the deflection of the pinion shaft is bound to happen. High force will together produce elastic deformation for the interface of the slewing commute and mounting structure. This deformation could also cause meshing problems.



·lubricating

The three influencing factors mentioned will result in high peak loads acting about the edge of the pinion hint, which may cause the actual lubricant film to rupture as well as direct metal contact will increase the chipping effect.



Xuzhou Wanda Slewing Bearing Co.,Ltd. is an experienced manufacturer and exporter of slewing bearing, which are usually mainly applied in dock machinery, mining machinery, welding equipment, construction vehicles, modular cars and small wind electricity systems etc. Slewing bearing can bear axial force, radial force and tilting minute. The diameter range of slewing bearing we can provide can be coming from 200 mm to 5000 mm.
