Abstract

The invention discloses a slide bearing with grooves and a lubricating method, wherein the slide bearing with grooves comprises an inner hole and an excircle; an inner groove is arranged in the middle of the inner hole and two ends of the excircle are provided with outer grooves; the outer grooves are provided with permanent magnets; a magnetofluid hole is formed between each outer groove and the middle of the slide bearing; the permanent magnets are annular permanent magnets; each outer groove is internally provided with a plurality of annular permanent magnets which are separated by permanent magnet baffle rings; and elastic baffle rings are arranged between the annular permanent magnets and axial end surfaces of the outer grooves. The tensioning degree among the magnets is regulated by regulating the number or widths of the elastic baffle rings among the magnets, the operation comprises the following step that water-based magnetic fluid lubricating agents are injected between the slide bearing and a matched surface of a rotary shaft through the magnetofluid hole, wherein the water-based magnetic fluid lubricating agents mainly comprise a water-based liquid carrier, water-based magnetic fluid nano Fe3O4 particles and polyaniline surface active agents. Lubrication without leakage can be realized, so that the slide bearing is environment-friendly, and can operate reliably, thus the service life of the slide bearing is prolonged.

Description

technical field [0001] The invention relates to the technical field of bearing lubrication, in particular to a sliding bearing with grooves and a lubrication method. Background technique [0002] The sliding bearings in the prior art are lubricated by oil. The disadvantage of the oil lubrication method is that end leakage is likely to occur at the end of the support lubrication, resulting in poor lubrication of the bearing or even failure of the bearing, causing damage to the equipment, and easy to cause environmental pollution after the lubricating oil leaks. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned deficiencies in the prior art; to provide a sliding bearing with a groove; the thickness of the magnetic fluid lubricating film at the groove of the bearing is larger, the pressure is smaller, and it is easier to realize full oil film lubrication. The friction and wear are reduced, and the water-based magnetic flui...
