Bearing bush with surface microporous structure and processing method thereof
ActiveCN102537066BIncreasing the thicknessImprove the extrusion effectBearing componentsMicrometerAlloy
The invention provides a bearing bush with surface microporous structures and a processing method. The bearing bush includes a bearing bush body, and the body comprises a metal bearing bush back and an antifriction alloy layer, wherein the antifriction alloy layer is a friction layer between the bearing bush and a journal. The bearing bush is characterized in that microporous structures are formed on the inner surface of the antifriction alloy layer through machining. The microporous structures are micropores formed by adopting the laser micromachining technique for machining, the micro-pores are arranged regularly, the diameters range from 150 micrometers to 200 micrometers, and the depths range from 35 micrometers to 50 micrometers. The bearing bush is provided with the microporous structures on the inner surface, can effectively improve the oil film bearing capability, and remarkably improves the lubrication effect.

PendingCN112814909AImprove volumetric efficiencyImprove reliabilityRotary/oscillating piston pump componentsLiquid fuel engine componentsGroove widthEngineering
The invention provides a flange, a pump body assembly, a rotary compressor and an air conditioner. The flange comprises a flange body, a bearing hole used for inserting a crankshaft is formed in the flange body, a vibration reduction ring groove is formed in the hole opening wall of the side, close to an eccentric part of the crankshaft, of the bearing hole, and a spiral oil guide groove is formed in the hole wall of the bearing hole; and the spiral oil guide groove comprises a first groove section located on a first hole section and a second groove section located on a second hole section, and the maximum groove width of the second groove section and the maximum groove depth of the first groove section are smaller than the minimum groove depth of the second groove section. According to the flange, the spiral oil guide groove on the first hole section, namely the first groove section, is designed into the shallow groove structure, so that the outer ring groove wall of the vibration reduction ring groove can be closer to the bearing hole, the sealing distance of the end part of the flange body and the matching position of a roller is increased, and the volume efficiency of a pump body structure is improved; and meanwhile, the phenomenon of opening collapse caused by too small wall thickness of the wall body between the vibration reduction ring groove and the bearing hole can be prevented.
