Sliding bearing capable of realizing self-aligning damping

Abstract

The invention discloses a sliding bearing capable of realizing self-aligning damping. The sliding bearing comprises a journal seat, a bearing cap, a bearing sleeve and multiple elastic pieces; a through hole is formed when the journal seat and the bearing cap are buckled together; the bearing sleeve comprises multiple inserting grooves formed in the axial direction of the bearing sleeve; the inserting grooves are formed in the outer side wall of the bearing sleeve; an included angle is formed by the depth direction of each inserting groove and the diameter direction of the bearing sleeve; eachof the journal seat and the bearing cap comprises multiple penetrating grooves; and one end of each elastic piece penetrates through the corresponding penetrating groove and is inserted in the corresponding inserting groove, and the other end of the elastic piece is fixed to the bearing cap or the journal seat. According to the sliding bearing, partial elastic pieces of the bearing sleeve allow the bearing sleeve to be compressed in the certain range, and the rest elastic pieces allow the bearing sleeve to be stretched in a certain range, so that the purpose of automatic alignment is achieved; and meanwhile, the amplitude of the journal seat and the amplitude of the bearing cap are very small under the action of the elastic pieces, so that the stability of the whole device can be improved.

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
