Analysis of Accuracy Class of Slewing BearingsThe slewing bearing is a standard part of hoisting machinery, and its gear accuracy grade should be between 7-11, which determines the stability of the slewing bearing (slewing bearing) transmission, the uniformity of the load distribution and the accura

Gear heat treatmentThe statement of gear heat treatment normally have two statement, normfalizing and tempering. The quenching of gear surface an processed according to customer's requirement, the hardness are in the range of 50HRC~60HRC. In different application, the gear quenching can divide into

Slewing ring is a large bearing that can bear comprehensive load. It can bear large axial, radial load and overturning moment at the same time. Once a problem occurs, it will make a variety of noises. How can we solve these noises? The rotary table bearing manufacturer takes you to explore.1. Contro

Many users do not know some knowledge about the processing of slewing ring (rotary table bearing). The following small editor of rotary table bearing manufacturer will introduce the causes of processing deformation:1、 Shrinkage of circleAfter the heat treatment of the tooth surface and raceway surfa

① Dust noise and Its Control CountermeasuresThere are dust and other foreign matters in the rotary table bearing (slewing ring), which will produce aperiodic vibration. The so-called dust sound, its vibration and noise are uncertain, with or without.Control measures for dust noise: improve the clean
