Six-oil-lobe sliding bearing

Abstract

A six-oil-lobe sliding bearing relates to the technical field of bearings and comprises a bearing body and bearing alloy, wherein the inner ring of the bearing body is connected with the bearing alloy; the bearing alloy is adhered to the bearing body through the static state or rotary casting manner; six bearing oil inlets are formed in the bearing body and divide the bearing body into fix bearingoil lobes; and a bearing oil draining groove is formed between every two adjacent bearing oil lobes. The six-oil-lobe sliding bearing is well adapted to stressed direction variation during the constant operating process of mechanical equipment from starting to the rated condition, and under the rated condition, the maximum temperature of a bearing oil film is lower than the maximum temperature ofthe oil film of other types of sliding bearings. The six-oil-lobe sliding bearing is suitable for the operation condition with the maximum linear velocity of 80m / s and the maximum bearing specific pressure of 1.5Mpa.

Description

Technical field: [0001] The invention relates to the technical field of bearings, in particular to a six-lobe sliding bearing. Background technique: [0002] At present, sliding bearings are used in various types of mechanical equipment. During the operation of the equipment, the bearing performance parameters (such as the minimum oil film thickness of the bearing, the maximum temperature of the bearing oil film, etc.), vibration parameters (such as the vibration acceleration of the mechanical equipment box, Rotor shaft center track displacement, etc.) have strict index requirements. The sliding bearing is suitable for gear transmission mechanical equipment that operates under multiple working conditions or is continuously affected by external alternating loads. The force direction of the sliding bearing will change or change periodically with the working conditions, so the sliding bearing used needs to be strong adaptability. [0003] At present, the commonly used sliding...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a six-lobe sliding bearing, which solves the problem of gear transmission mechanical equipment that operates under multiple working conditions or is continuously affected by external alternating loads. The force direction of the sliding bearing will change or change periodically with the working conditions, but the structural form of the sliding bearing used has a technical problem of poor adaptability to the change of the force direction
