Embodiment Construction

[0013] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0014] Such as figure 1 The steering gear bearing shown has a stamped outer ring 1 and a cage 3, the outer ring 1 is provided with a needle roller 2 fixed by the cage 3, the outer ring 1 and the cage 3 are split structures, It is easy to install and place, ensuring flexible, convenient and light operation.

[0015] The material of the cage 3 is nylon; the thickness of the nitriding layer on the surface of the outer ring 1 is 0.02-0.06mm, and the surface of the outer ring 1 has undergone soft nitriding treatment, so that the hardness of the surface of the outer ring 1 is enhanced, and its surface hardness is 400 ~600HV 1 ; Both ends of the needle roller 2 ar...

Abstract

The invention relates to a steering engine bearing which is provided with an outer ring and a retainer which are formed in a stamping mode. A quill roller which is fixed through the retainer is arranged on the outer ring, and the outer ring and the retainer are in a split-type structure. The outer ring of the bearing carries out automatic hemming before heat treatment, and finally carries out heat treatment quenching, so the steering engine bearing ensures parallel errors of a hemming and a reference edge, and also ensures dimensional stability.

Description

technical field [0001] The invention relates to the technical field of roller bearings, in particular to a steering gear bearing. Background technique [0002] Generally, the curling of bearings is done after heat treatment. Such a process is difficult to ensure the parallel difference between the curling and the reference edge, and it is also difficult to guarantee the dimensional stability. Contents of the invention [0003] The technical problem to be solved by the present invention is: the present invention provides a steering gear bearing, the outer ring of which is automatically crimped before heat treatment, and finally heat-treated and quenched to ensure the parallel difference between the crimp and the reference edge, and the dimensional stability Also guaranteed. [0004] The technical solution adopted by the present invention to solve the technical problem is: a steering gear bearing with a stamped outer ring and a cage, the outer ring is provided with needle r...
