Bearing runout can be divided into synchronous runout and asynchronous runout. The influence of synchronous runout on the overall runout of the worktable can be minimized by grinding the worktable, but the influence of asynchronous runout cannot be eliminated in this link. It is determined by the outer diameter tolerance and roundness of the rollers. Th...

The installation surface of the shaft and the ring gear is required to have the same flatness, perpendicularity, roundness and cylindricity as the fine bearing. Controlling these form and position common services can not only achieve better installation accuracy, but also prevent excessive eccentricity of the inner and outer rings of the bearing from ca...

In the cutting test of the vertical lathe, great attention is paid to the end face and outer circle roughness of the workpiece, and one of the keys to determine its quality is the rigidity of the system. The system rigidity includes the rigidity of the frame structure, the rigidity of the support bearing, etc., during which the rigidity of the bearing o...

First, whether the distribution of bearing load is reasonableBearing assemblies in a lack of a consistent support surface, a common mistake during the design phase of the support structure is that the slewing bearing assumes that the support structure is sufficiently rigid.Second, is the bolt strong enough?The main guarantee is to choose the right slewi...

First of all, we must do a good job in the inspection and maintenance of the slewing bearing. First use the slewing bearing for 100 working hours to check the bolt moment moment. Assuming that about 10% of the bolts are loose, check again after the 200th working hour. After that, check every 500 working hours; reduce the check distance for extreme loads...
