摘　　要：介绍了浮动油封的工作原理和激光表面处理工艺。采用CO2激光对45#钢激光表面淬火后,其变形很小,表面硬度很高,能够达到浮动油封工作的技术要求。The technologies of laser surface hardening and the working principals of floating oil seal are introduced. The laser surface hardening for floating oil seal made of 45 steel was tested by using CO2 laser beam. Test results show that deformations in laser hardened steel was negligible to influence its precision. The surface hardness of laser trans（ormation hardened samples improves apparently. The process could well accommodate the working conditions of the floating oil seal.

关 键 词：浮动油封 激光淬火 耐磨性 硬度
