A processing method of cylindrical roller bearing cage

Abstract

The invention provides a processing method for a cylindrical roller bearing retainer and belongs to the technical field of bearing processing. The method comprises the following steps: mounting and fixing a mandrel on a machine tool; fixing a retainer base to be processed on the mandrel for processing a rivet joint and a pocket, wherein during processing, a step is required to be reserved at one end of the retainer base and surrounds the inner wall of the retainer base, a clamping platform is arranged on the mandrel and the fixing of the retainer base is completed through the step and the clamping platform; after processing, taking down the retainer base; fixing two retainer covers on the mandrel for processing after the two retainer covers are overlapped; after the retainer covers are processed, assembling the retainer covers and the retainer base together; carrying out finish turning on inner and outer diameters until the inner and outer diameters meet processing requirement. According to the method, the cylindrical pocket and the rivet joint are processed through one-time positioning, so that the processing quality is improved, and only the first retainer is required to be positioned and subjected to tool setting, therefore, production efficiency is improved greatly.

Description

technical field [0001] The invention relates to bearing processing in the mechanical field, in particular to a processing method for a cylindrical roller bearing cage. Background technique [0002] Many cages of cylindrical roller bearings are in the form of pillars. The pillar-shaped cage is riveted by combining the cage seat and the cage cover. It is easy to assemble. It will not fall out in any direction and belongs to the roller guide. Compared with inner ring guiding or outer ring guiding, this guiding method keeps a large gap between the cage and the inner and outer rings at the same time, which is conducive to the entry of lubricating oil, thereby reducing heat generation and improving the service life of the bearing. [0003] This type of cage consists of two parts, as attached figure 1 and 2 As shown, the riveting head on the cage seat passes through the hole on the cage cover, and forms an integral structure after riveting. The difficulty of processing the cage...

Problems solved by technology

[0005] In order to solve the problem in the prior art that the positional relationship between the riveting head and the cylindrical pocket on the cage seat is different due to positioning errors and reduce the quality of the cage, the present invention provides a processing method for a cylindrical roller bearing cage. Changing the processing method and combining it with the supporting mold realizes the accurate positioning of the riveted joint and the cylindrical pocket on the cage seat, thereby improving the processing efficiency and quality of the cage
