A self-aligning shock-absorbing sliding bearing

Abstract

A self-aligning shock-absorbing sliding bearing includes a journal seat, a bearing cover, a bearing sleeve, and a plurality of shrapnel. The through hole is formed when the journal seat and the bearing cover are fastened together. The bearing sleeve includes a plurality of slots opened along the axial direction of the bearing sleeve. The slot is opened on the outer side wall of the bearing sleeve. The depth direction of the slot and the diameter direction of the bearing sleeve include an included angle. The bearing seat and the bearing cover respectively include a plurality of through grooves. One end of the elastic piece passes through the through groove and is inserted into the slot, and the other end of the elastic piece is fixed on the bearing cap or journal seat. In this sliding bearing, the shrapnel of the bearing sleeve allows the bearing sleeve to be compressed to a certain extent, while the other part of the shrapnel allows the bearing sleeve to be stretched to a certain extent, so as to achieve the purpose of self-aligning. At the same time, due to The effect of the shrapnel makes the vibration amplitude of the journal seat and the bearing cover very small, thereby improving the stability of the whole device.

Description

technical field [0001] The invention relates to the technical field of transmission, in particular to a self-aligning shock-absorbing sliding bearing. Background technique [0002] Bearings are 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. As a large category of bearings, sliding bearings are bearings that work under sliding friction. Sliding bearings have the characteristics of stable, reliable and noiseless operation. However, in the fields of metallurgy, chemical industry, etc., many large-scale rotary equipment have complex working conditions and large foundation spans. Due to factors such as uneven site and human operation errors during equipment processing and on-site installation, it is difficult to guarantee the coaxiality, which makes the equipment in operation. There are great potential safety hazards. Onc...

However, in the fields of metallurgy, chemical industry, etc., many large-scale rotary equipment have complex working conditions and large foundation spans. Due to factors such as uneven site and human operation errors during equipment processing and on-site installation, it is difficult to guarantee the coaxiality, which makes the equipment in operation. There are great potential safety hazards. Once an accident occurs, it will not only bring immeasurable economic losses to the enterprise, but may even cause casualties
