Abstract

The invention relates to the field of motors, and discloses a tilting pad type oil bearing and a motor. The tilting pad type oil bearing comprises a bearing body (10), multiple bearing pad bodies (20), multiple bearing pad supports (30) and multiple elastomers (40), wherein the bearing pad supports (30) movably sets the bearing pad bodies (20) on the bearing body (10); the multiple elastomers (40)are respectively arranged on a first matching surface (12) of the bearing body (10), second matching surfaces (22) of the bearing pad bodies (20) and multiple setting grooves (50) surrounded and formed by adjacent bearing pad supports (30); one side surface of each elastomer (40) is laminated with one second matching surface (22); and the other side surface of each elastomer (40) is laminated with the first matching surface (12) and is at least partially contained with a lubricant. The tilting pad type oil bearing is simple to machine and produce and small in assembling error, and is capableof running at a high speed for a long time without setting a complicated oil supply lubrication system.

Description

Technical field [0001] The present invention relates to the field of electric motors, in particular to a tilting shoe type oil-impregnated bearing and electric motors. Background technique [0002] Existing motors mainly adopt ball bearings, which have complicated ball bearing technology, high cost, and small bearing area. Especially when the motor is running at high speed, it is very easy to cause serious mechanical damage. Moreover, the ball bearing does not have a centering function. When the motor is subjected to external eccentric force, it will cause the motor to jam and burn, which will seriously affect the service life of the motor. [0003] However, the tilting-pad oil-impregnated bearing, as a bearing used in large-scale high-speed electrical equipment such as steam turbines, requires a complicated oil supply system, and it is difficult to achieve low cost and miniaturization. Summary of the invention [0004] The purpose of the present invention is to overcome the probl...
