Problems solved by technology

[0002] Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling element and cage. The inner ring is used to assemble with the journal, and the outer ring is used to assemble with the bearing seat hole. Usually, the inner ring rotates with the journal. The outer ring is fixed. On the one hand, it is inconvenient to install the outer ring with the bearing seat. On the other hand, during use, the force point of the outer ring is not very firm, and when the force is large, the axial direction of the outer ring will occur. Displacement, which affects the stability of the bearing work and shortens the service life of the bearing

Embodiment Construction

[0012] Such as figure 1 As shown, a bearing outer ring includes an outer ring body 1. The outer peripheral surface of the outer ring body 1 is conical. The diameter of one end surface of the outer ring body 1 is larger than the diameter of the other end surface. A raceway 3 for cylindrical rollers to roll and two seal grooves 2 for installing seal rings are provided. The two seal grooves 2 are respectively located on both sides of the raceway 3, and the raceway 3 is provided with a lubricating liner 4 ; Threads are provided on the tapered surface of the outer ring body 1 .

[0013] During the long-term use of the bearing, the liner in the raceway will be gradually worn out. In order to facilitate maintenance and replacement, the raceway 3 and the outer ring body 1 can be detachably connected.

[0014] In the present invention, the outer surface of the outer ring body is set as a conical surface and threads are provided on the conical surface. When installing with the bearing ...

Abstract

The invention discloses a bearing outer ring which comprises an outer ring body; the outer peripheral surface of the outer ring body is shaped like a conical surface; the diameter of one end face of the outer ring body is greater than that of the other end face; a roller path for the rolling of cylindrical rollers and two sealing grooves for mounting sealing rings are circumferentially arranged on the inner wall of the outer ring body; the two sealing grooves are positioned in the two sides of the rolling path respectively; a lubricating lining gasket is arranged in the rolling path; a thread is formed on the conical surface of the outer ring body. According to the bearing outer ring, the outer surface of the outer ring body is arranged to be the conical surface on which the thread is formed; when the bearing outer ring is mounted with a bearing pedestal, a threaded structure matched with the outer ring body is arranged on the inner wall of the bearing pedestal, the smaller-diameter end of the outer ring body is mounted at first, and then the bearing pedestal is firmly connected with the outer ring in a threaded connection way, so that positioning is firm, axial rotation is avoided, the working stability is good, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of bearings, in particular to a bearing outer ring. Background technique [0002] Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling element and cage. The inner ring is used to assemble with the journal, and the outer ring is used to assemble with the bearing seat hole. Usually, the inner ring rotates with the journal. The outer ring is fixed. On the one hand, it is inconvenient to install the outer ring with the bearing seat. On the other hand, during use, the force point of the outer ring is not very firm, and when the force is large, the axial direction of the outer ring will occur. Displacement, which affects the stability of the bearing work and shortens the service life of the bearing. Contents of the invention [0003] In order to solve the problems existing in the prior art, the object of the present invention is to provide a bearing outer ring with convenient i...
