Rolling piston compressors, which are widely used in refrigeration systems, contain a vane-vane slot friction pair that significantly affects its mechanical efficiency and reliability. In this study, a new simulation model considering the deformation and detailed groove design of the vane-vane slot system is presented. The simulation results show that the vane slot's maximum wear depth increased by approximately 110% after considering the deformation. The optimal design of the vertical groove can reduce friction loss and wear. Compared with the situation without a vertical groove, the optimal vertical groove design can reduce the friction loss of the vane by 17.59%, and manufacturers have begun to adopt this scheme.

广泛用于制冷系统的滚动活塞式压缩机包含一个叶片-叶片槽摩擦副，这会显着影响其机械效率和可靠性。在这项研究中，提出了一种新的仿真模型，该模型考虑了叶片-叶片槽系统的变形和详细的凹槽设计。仿真结果表明，考虑变形后叶片槽的最大磨损深度增加了约110%。垂直槽的优化设计可减少摩擦损失和磨损。与没有竖槽的情况相比，优化的竖槽设计可以将叶片的摩擦损失降低17.59%，厂家已经开始采用这种方案。
