Abstract

The invention discloses a planar needle roller thrust bearing with gaskets embedded into a plastic retainer. The planar needle roller thrust bearing comprises a rolling body assembly and two gaskets, wherein the two gaskets are respectively embedded and fixed on two sides of the rolling body assembly; the rolling body assembly comprises the plastic retainer and needle rollers; a plurality of needle roller notches are formed in the plastic retainer and are arranged in the needle roller notches; a seam allowance ring groove is formed in each of two sides of the plastic retainer; each gasket is arranged in the corresponding seam allowance ring groove; a circle of seam allowances are formed in the groove wall, close to the circle center, of each seam allowance ring groove; a circle of inner chamfers are arranged on the inner circumference of each gasket; the inner chamfers are matched with the seam allowances. In the way, according to the planar needle roller thrust bearing with the gaskets embedded into the plastic retainer, the problems of missing installation of thrust gaskets and missing of needles are solved, and direct rubbing of the needle rollers and the retainer against the working surface is reduced, so that the service life of the bearing is prolonged.

Description

technical field [0001] The invention relates to the technical field of bearing processing and manufacturing, in particular to a plane thrust needle roller bearing in which a gasket is embedded in a plastic cage. Background technique [0002] Most of the existing planar thrust needle roller bearings have thrust cage components with needle rollers and thrust washers are scattered, and there are phenomena of missing thrust gaskets and missing needles, which will cause safety hazards brought by the bearings during work, and cause customers and bring unnecessary losses to the enterprise. Contents of the invention [0003] The main technical problem to be solved by the invention is to provide a plane thrust needle roller bearing in which the gasket is embedded in a plastic cage, which solves the phenomenon that the thrust gasket is missing and the needle is missing. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is...
