Rotating bearing assembly method

Abstract

The invention discloses a rotating bearing assembly method. A first positioning pin hole and a first guide hole are formed in a rotating bearing, the inner ring of the rotating bearing is fixed on a chassis, and a positioning pin is installed in the first positioning pin hole; a second positioning pin hole and a second guide hole are formed in a rotating platform; the rotating platform is hoistedabove the rotating bearing; a guide pin is installed in the second guide hole, and the guide pin is directed to the rotating bearing; the rotating platform is lowered and the direction of the rotatingplatform is adjusted so that the guide pin is inserted into the first guide hole; the rotating platform is continuously lowered until the bottom surface of a gear under a rotating speed reducer is close to the upper end surface of the rotating bearing; an adjusting hook is used to adjust the gear under the rotating speed reducer to a position where meshing is convenient; the rotating platform islowered continuously until the positioning pin is inserted into the second positioning pin hole; the guide pin is taken out and a fixing bolt is mounted. The method aims to improve assembly efficiency.

Description

technical field [0001] The invention belongs to the technical field of bearings, and more particularly, relates to a slewing bearing assembly method. Background technique [0002] The slewing bearing is a new type of mechanical parts. It consists of inner and outer rings, rolling elements, etc. It is a large bearing that can bear comprehensive loads, and can bear large axial and radial loads and overturning moments at the same time. When installing the slewing bearing, it is necessary to install the slewing bearing on the chassis, hoist the slewing platform, drop it slowly, and observe the meshing between the pinion and the large gear at this time. If the meshing is improper, raise the platform , toggle the pinion, and then continue to drop the slewing platform, sometimes it takes several adjustments to assemble successfully, or the slewing bearing is installed on the chassis, and then the position of the slewing bearing is directly determined by the pin positioning of the o...

AI Technical Summary

Problems solved by technology

When installing the slewing bearing, it is necessary to install the slewing bearing on the chassis, hoist the slewing platform, and slowly drop it to observe the meshing situation between the small gear and the large gear at this time. If the meshing is not proper, raise the platform , move the pinion, and then continue to drop the slewing platform. Sometimes it needs several adjustments to assemble successfully, or install the slewing ring on the chassis, and then directly determine the position of the slewing ring through the pin positioning of the outer ring of the slewing ring, and then Lift the slewing reducer for installation, but because the mesh between the slewing reducer gear and the gear of the slewing support is not easy to adjust, a lot of time will be wasted on adjusting the angle of the pinion
