Novel knuckle bearing convenient to mount and replace

Abstract

The invention provides a novel knuckle bearing convenient to mount and replace. The knuckle bearing comprises a bearing outer ring and an inner ring; the inner ring is located in the bearing outer ring; the bearing outer ring comprises an outer ring body and a fixing ring; a first flange is arranged at one end of the outer ring body; an outer thread is arranged at the other end of the outer ring body; an inner thread is arranged on the inner surface of the fixing ring; a second flange is arranged at one end of the outer surface; and the outer ring is in threaded connection with the fixing ring. According to the novel knuckle bearing convenient to mount and replace, the appearance structure of a traditional knuckle bearing is changed, the bearing outer ring is divided into two parts including the outer ring body and the fixing ring, and the outer ring body and the fixing ring are connected in a threaded manner to fix the bearing, so that the bearing can be mounted and dismounted conveniently, and the bearing can be screwed down after being normally mounted; and the bearing is consistent with the traditional bearing in outline dimension, service life and bearing capacity, and is convenient to popularize and apply.

Description

technical field [0001] The invention belongs to the field of sliding bearings, and in particular relates to a novel joint bearing which is convenient to install and replace. Background technique [0002] According to the development of my country's aerospace industry, the requirements for joint bearings have become higher and higher. The disadvantages of the existing technology are: [0003] 1. Aerospace equipment requires frequent maintenance. Due to the structural characteristics of joint bearings, flanges are often used for installation, and bearing replacement is time-consuming and laborious. [0004] 2. It is difficult to assemble the bearing, and it is necessary to use extrusion equipment and specific tooling for flanging on site, which is time-consuming and laborious. When replacing, it is more necessary to carry out local destruction. While the replacement is difficult, it is easier to cause damage to matching parts such as bearing seats, resulting in greater losses...

Problems solved by technology

[0003] 1. Aerospace equipment needs frequent maintenance. Due to the structural characteristics of joint bearings, flanges are often used for installation, and bearing replacement is time-consuming and laborious.

[0004] 2. The assembly of the bearing is difficult, and it is necessary to use extrusion equipment and specific tooling for flanging on site, which is time-consuming and laborious

When replacing, it is more necessary to carry out local damage. While the replacement is difficult, it is easier to damage the bearing seat and other matching parts, resulting in greater losses.
