用于油压和空压机上的滑动轴承,随着对油压和空压机性能要求的不断提高以及为适应高负荷、高速、高温的各种苛刻运转条件,虽然相应地为各种滑动轴承提供了各类适用的材料,但是在滑动轴承的设计中必需正确掌握润滑机构和材料特性。现将各种轴承合金及干式轴承材料的特性及在油压和空压机上的应用分述如下。一、轴承的润滑机构滑动轴承的润滑机构按其类型可分为四类:①液体润滑:轴和轴承间有液体油膜存在,即使二者处于彼此互不接触的状态。此状况下的轴承寿命属于半永
For the oil pressure and air compressor sliding bearings, with the hydraulic and air compressor performance requirements continue to improve and to meet the high load, high speed, high temperature and a variety of harsh operating conditions, while a variety of sliding Bearings provide a variety of suitable materials, but in the design of plain bearings must be properly grasp the lubricating mechanism and material properties. Now a variety of bearing alloy and dry bearing material characteristics and applications in the hydraulic and air compressor are described below. First, the bearing lubrication mechanism Lubrication mechanism of sliding bearings can be divided into four categories according to their type: ① liquid lubrication: there is a liquid film between the shaft and the bearing exists, even if the two are in contact with each other state. Bearing life in this condition belongs to semi-permanent
