随着机器工业制造技术的发展和产品使用性能的提高,从70年代开始,三层复合材料轴承和镶嵌轴承等自润滑轴承获得了越来越广泛的应用。但是这些传统的自润滑材料都存在着一定的不足或缺陷。例如,三层复合材料轴承表面采用热塑性树脂POM或PTFE作为减摩层,在工况温度升高时,其硬度、承载能力以及几何精度都会显著降低,严重时
With the development of machine manufacturing technology and improvement of product performance, self-lubricating bearings such as three-layer composite bearings and inlaid bearings have gained more and more widespread applications since the 1970s. However, these traditional self-lubricating materials have some shortcomings or defects. For example, the three-layered composite bearing surface using thermoplastic resin POM or PTFE as the anti-friction layer, the working temperature, the hardness, load carrying capacity and geometric accuracy will be significantly reduced, serious
