Pressed cage for cylindrical roller bearing and manufacturing process thereof

Abstract

The invention specifically relates to a pressed cage for a cylindrical roller bearing, which has the advantages of long service life, less pollution to environment in the production process and low cost, and a manufacturing process thereof, and belongs to the technical field of cylindrical bearings, wherein the cage comprises one or more pairs of circular ring parts and a plurality of cylinder parts; and the plurality of cylinder parts are arranged in a circumferential direction of the circular ring parts at equal intervals so as to form a plurality of pocket parts with storage rollers; and two equally-spaced bosses are arranged on two side end surfaces of each pocket, respectively. The pressed cage for the cylindrical roller bearing and the manufacturing process thereof, provided by the invention, are advantaged in that the service life of the bearing is prolonged and the production cost of the bearing is reduced because the product is manufactured from excellent plates through an optimized smelting production procedure.

Description

technical field [0001] The invention belongs to the technical field of cylindrical bearings, in particular to a cylindrical roller bearing stamping cage with long service life, less environmental pollution in the production process, and low cost and its manufacturing process. Background technique [0002] As we all know, the cage is one of the important parts of the rolling bearing. Its function is to guide the rolling elements to run normally during the bearing work, and keep the rolling elements from the bearing at any time. In addition, in order to obtain better operating conditions or installation conditions, the cage generally needs to control the amount of movement of the rolling elements relative to the cage, neither restricting the rolling elements too narrow to prevent free rotation, nor too loose to assemble or Difficult to install. Generally, the cage keeps the rolling elements from breaking away by constraining the outer surface of the rolling elements, whic...

AI Technical Summary

Problems solved by technology

In the prior art of cylindrical roller bearings, the production process is cumbersome, and it needs to go through a smelting process, which not only pollutes the environment, but also increases the cost; the cage materials are generally copper and ductile iron, which are made of The cage often wears off the powder during the rotation process. Its rotation principle is to contact the roller branch line surface, and it is possible to directly scrape the lubricating oil during the process; however, the bearing will rotate at high speed during installation and use. And accompanied by vibration, if there is interference from the reduction of lubricating oil and the abrasion of powder, this will not only increase the wear of the bearing, but also greatly reduce the service life of the bearing
