关节轴承固体润滑处理工艺

介绍一种关节轴承固体润滑处理技术,制备的固体润滑膜以无机盐和活性金属离子为黏结剂,提高了膜层的耐压强度和耐温性能;以石墨和二硫化钼复合材料为润滑剂,提高了关节轴承在不同工况条件下的承载能力和润滑性。经固体润滑处理的轴承内圈外表面润滑膜层均匀、外观细致,实际使用效果良好。经检测,形成的固体润滑膜与金属基体有较强的结合力,在特殊工况条件下能够满足承载和润滑性能的要求。

Research on Solid-lubrication Craft of Joint Bearing

A solid-lubrication technology of joint bearing was introduced.A solid lubrication film was prepared,which used inorganic salt and active metal ions as the binders to improve the compression strength and heat resistance properties of film layer,used graphite and molybdenum disulfide composite materials as the lubricant to improve the bearing loading capacity and the lubrication performance of the joint bearings under different working conditions.The lubrication film of the bearing inner ring surface treated by solid lubrication is uniform and has good use effect.Test result shows that the formed solid lubrication film has strong binding force with the metal substrate,which can meet the requirements of bearing loading capacity and lubrication performance of joint bearing under the special working conditions.
