It is not easy to judge the damage of the retainer in the double volleyball turntable bearing, and the failure problem is not obvious in use. Today, I will talk about the reasons for the damage of double volleyball turntable bearing retainer, and make a comprehensive analysis.The reasons for the dam

There is no way to prevent the wear of slewing bearing. Some customers want to reduce the cost, they want to install elastic washer on the slewing ring to reduce this kind of wear, in fact, it is a very serious misconception! Although the wear of slewing bearing can not be prevented, people can repa

First of all, we should pay attention to three problems when we choose slewing bearing: load, bolt strength and whether the bolt hole is uniform.If the bearing is installed on the support surface which lacks integrity, local deformation will change the load, resulting in different load sizes of the

Slewing ring is a kind of large-size thin-walled parts, widely used in construction machinery, wind power and other fields. The slewing system of slewing ring is redundantly driven by the meshing of several circumferential distributed pinions with the inner ring teeth of slewing ring, so the deforma

Rotary table bearings are used in many fields such as engineering machinery, ships, wind power and so on. What are the commonly used materials of rotary table bearings?Usually, 50Mn is selected for the rotary table bearing housing, but sometimes 42CrMo is selected to meet the host requirements of sp

Gear shaping is also a widely used tooth profile machining method, which is often carried out together with gear hobbing. It is equivalent to meshing a pair of cylindrical gears, and the gear shaper cutter is equivalent to a modified gear. During gear shaping, the gear shaping cutter moves up and do
