Types of the slewing bearing
  • 2014-05-15 06:29:00

The commonly used structural forms of slewing bearings are single-row, double-row four-point contact ball slewing bearings, double-row angular contact inference ball slewing bearings, crossed cylindrical roller and crossed tapered roller slewing bearings, three-row cylindrical roller slewing bearings, ball bearings. Column hybrid slewing bearing and ...

Runout accuracy of slewing bearing
  • 2018-05-14 09:40:00

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....

The shape and position of the slewing bearing
  • 2018-04-10 05:43:00

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...

Axial preload of slewing bearing
  • 2018-03-15 08:43:00

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 bearin...
