a thrust washer

Abstract

The invention relates to the field of industrial parts, specifically a thrust washer, including a shaft subassembly, a shaft female assembly and a connecting assembly, the opposite sides of the shaft female assembly are fixedly connected, and the opposite sides of the shaft female assembly are clamped There is a shaft piece wood assembly, the shaft piece subassembly includes a first shaft piece, and the shaft piece mother assembly includes a second shaft piece. By setting the connecting components, it is convenient to stably connect the shaft plate and the seat plate of the thrust pad, so as to avoid that the thrust bearing is often subject to the reciprocating centripetal effect during transportation, so that the shaft plate and the gasket of the thrust bearing often reciprocate Offset, easy to cause shaking and loosening, improve the stability of the thrust bearing and prevent it from falling apart. By setting the sliding assembly, the roller shaft of the sliding assembly and the inner ring of the seat plate of the thrust bearing are lapped to maintain the smooth rotation of the seat plate. At the same time, the inner rings of the roller shaft and the seat plate are provided with matching transverse tooth grooves to avoid the relative distance between the shaft plate and the seat plate, which is convenient for installation and disassembly.

Description

technical field [0001] The invention relates to the field of industrial parts, in particular to a thrust washer. Background technique [0002] Thrust bearings are generally composed of two thrust washers or more thrust washers and a number of rolling elements. Generally, thrust washers are divided into shaft pieces and seat pieces. The most common types of rolling elements are generally made of iron or copper. The quality cage is combined into a whole. The most common type of bearing is steel ball thrust bearing. Thrust bearings are designed and used to bear axial loads. They are also called axial bearings. These bearings include thrust ball bearings, thrust Cylindrical roller bearings, thrust needle roller bearings, thrust tapered roller bearings and thrust self-aligning roller bearings, thrust washers are annular plates or two semi-annular plates usually used with radial sliding bearings to withstand axial loads , The thrust washer is a standard part used in conjunction w...

AI Technical Summary

Problems solved by technology

[0003] Since the thrust bearing is composed of two thrust washers or more thrust washers and a number of rolling elements, the shaft and seat of the thrust washers are parallel and have no stable connection with each other. During the transportation of freight trains, when encountering a sharp turn on the track, because the body is long, the body is subjected to the centripetal force of the inner curved side of the body during the sharp turn, which makes the body tilt to a certain extent during operation. Due to the effect of centripetal force, there is also a tendency of inclination. In the winding mountain area, the thrust bearing is often subjected to reciprocating centripetal effect, so that the shaft plate and gasket of the thrust bearing often reciprocate and shift, which is easy to cause shaking and loosening. The existing There is no direct and stable connection relationship between the shaft piece and the seat piece during the specific use process, so that when the thrust bearing is used vertically, the thrust washer is not easy to install when installed, and it is easy to fall off when disassembled. The connection method hinders the overall rotation of the thrust bearing
