Double-half-outer-ring self-aligning roller bearing for stirring vehicle

Abstract

The invention discloses a double-half-outer-ring self-aligning roller bearing for a stirring vehicle. The double-half-outer-ring self-aligning roller bearing comprises an inner ring, an outer ring, self-aligning rollers, a connection ring 5, two retainers and a movable middle space ring. The outer ring is composed of two half outer ring bodies which are fixed through the connection ring. The inner ring and the outer ring are both of an annular structure and are concentrically arranged. The two retainers are concentrically arranged on the inner ring in parallel. The retainers are provided with a plurality of rectangular pocket holes, the self-aligning rollers are arranged in the rectangular pocket holes, and the movable middle space ring is arranged in a narrow space defined by the inner ring, the two rows of self-aligning rollers and the two retainers. The double-half-outer-ring self-aligning roller bearing has the advantages of being high in loading capacity, large in self-aligning angle, long in service life, high in reliability and the like.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a self-aligning roller bearing with double half outer rings for a mixer truck. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling elements and cage. According to the shape of rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings. [0003] In recent years, with the rapid development of the construction industry, the application of cement mixer trucks has become more and more extensive, but the supporting bearings have always been a blank in China. Due to the particularity of the working conditions of the bearing, the bearing often works continuously, th...

AI Technical Summary

Problems solved by technology

Due to the particularity of the working conditions of the bearing, the bearing often works continuously, the load is very large, and it is accompanied by an impact load. The spherical roller bearing of the ordinary structure cannot meet the technical requirements of high load capacity and large alignment angle, which directly leads to the failure of the bearing. Very low lifetime and reliability
