Abstract

The invention discloses a ferrofluid-lubricated sliding bearing with an annular groove. The ferrofluid-lubricated sliding bearing comprises a sliding bearing body, wherein the wall of the sliding bearing body is provided with ferrofluid holes, the external circle of the sliding bearing body is provided with at least one annular groove, the annular groove is internally provided with an annular magnet, an elastic check ring is axially arranged between the annular magnet and the sliding bearing body, at least one annular square groove is formed along the radial direction of an inner hole of the sliding bearing body, and the axes of the ferrofluid holes are set along the radial direction of the sliding bearing body. According to the ferrofluid-lubricated sliding bearing, the cooling of the sliding bearing body is realized, the heat dissipation speed of a lubricant is accelerated, the heat conduction area of the lubricant is enlarged, the temperature of the lubricant is lowered, the use reliability of the sliding bearing body is improved, and the service life of the sliding bearing is prolonged.

Description

technical field [0001] The invention relates to the technical field of sliding bearings, in particular to a magnetic fluid lubricated sliding bearing with an annular groove. Background technique [0002] The magnetic fluid lubricated sliding bearing lubricant with annular grooves in the prior art has a high viscosity. Since the mating surface of the sliding bearing inner hole is a smooth surface, the friction temperature rises greatly during high-speed operation, causing the lubrication effect of the sliding bearing to change. Poor and poor heat dissipation performance, due to poor lubrication and poor heat dissipation performance, the reliability and service life of the sliding bearing are affected. In severe cases, it may even cause high-temperature lubrication failure of the bearing, cause equipment failure, and bring immeasurable losses. Contents of the invention [0003] In order to solve the above-mentioned deficiencies in the prior art, the present invention provid...
