Embodiment

[0019] Such as figure 1 As shown, a needle roller bearing is a combined bearing, and the needle roller bearing includes a ferrule 1, a needle roller 2, a first cage 3, a second cage 6, a steel ball 4, a washer 5 and Outer cover 7, after the needle roller 2 is installed on the first cage 3, it is installed in the inner diameter of the ferrule 1 together with the first cage 3, and after the steel ball 4 is installed on the second cage 6 , together with the second cage 6 is installed between the end face of the ferrule 1 and the washer 5 , and the outer cover 7 connects the ferrule 1 and the washer 5 .

[0020] The needle roller 2, the inner diameter of the ferrule and the first cage 3 form a needle roller bearing without an inner ring. The end face of the ferrule, the second cage 6, the steel ball 4 and the washer 5 form a thrust ball bearing.

[0021] The machining dimension tolerance of bearing parts adopts high-precision grade; the ferrule is designed with thick-walled stru...

Abstract

The invention relates to a rolling needle bearing. The rolling needle bearing is a combined bearing and comprises a ferrule, a rolling needle, a first holding frame, a second holding frame, steel balls, a gasket and an outer cover, wherein after the rolling needle is mounted on the first holding frame, the rolling needle and the first holding frame are mounted along the inner diameter in the ferrule, after the steel balls are mounted on the second holding frame, the steel balls and the second holding frame are mounted between the end face of the ferrule and the gasket, and the outer cover is connected with the ferrule and the gasket. Compared with the prior art, the rolling needle bearing has the advantages of low noise, long service life, compact structure, high reliability, wide application rang and adaptability, easiness in mounting and the like.

Description

technical field [0001] The invention relates to a bearing, in particular to a needle roller bearing. Background technique [0002] In actual use, more and more bearings are required to withstand combined loads, but at the same time there are corresponding requirements for bearing strength, installation space, simple installation, noise requirements, life requirements, and load bearing. However, the existing bearings can only be installed individually, and the installation error and installation space are also large, and the comprehensive performance is not strong. Contents of the invention [0003] The object of the present invention is to provide a needle roller bearing with low noise reduction, long service life, compact structure, high reliability, wide application range, wide adaptability and easy installation in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through the following technical...
