Abstract

The invention belongs to the technical field of bearings, and relates to a novel bidirectional thrust angular-contact ball bearing with a disc-type nylon cage, which consists of an outer ring, inner rings, a steel ball, the cage and a spacer ring, wherein the outer ring and the inner rings are connected through the steel ball; two inner rings are connected through the spacer ring; the steel ball is arranged in the cage; the cage is made of engineering plastic nylon; a ball pocket of the cage consists of a spherical surface, a corresponding spherical surface, a cylindrical surface and a corresponding cylindrical surface; and the spherical surface and the corresponding spherical surface are equal in curvature. The ball bearing has the advantages that the bearing is resistant to repeated impact shock, reduces the shock noise of hosts, and is strong in cage shock absorbency, good in wear-resisting property, low in friction coefficient and excellent in self-lubricity.

Description

technical field [0001] The invention belongs to the technical field of bearings, and relates to a novel disc-type nylon cage bidirectional thrust angular contact ball bearing, which is applied to the fields of precision numerical control milling machines, boring machines, machining centers and other machine tools. Background technique [0002] With the continuous development of my country's machine tool industry, especially the continuous update of the machine tool structure, the precision requirements of some precision CNC milling machines, boring machines, machining centers and other spindles are getting higher and higher, and the noise is getting lower and lower. The old structural bearings supporting the precision spindle have been difficult to meet the requirements of high precision, low friction and low noise of machine tools. [0003] Aiming at the requirements of precision spindles, a new disc-type nylon cage bidirectional thrust angular contact ball bearing was inve...
