讨论了涡旋压缩机的设计问题。推力轴承是用于空调和制冷中长时间运行的涡旋压缩机的关键零件。轴向推力和力矩都对推力轴承产生影响。应用拉姆巴格（Rumbarger）理论描述了推力轴承的载荷状态。如何优选涡旋卷体的几何形状也是设计者所关心的主要问题。阐述了在考虑稳定运行条件、重量、轴向推力和卷体外径时如何优选涡旋卷体的几何形状问题。在预先确定推力轴承外径尺寸时,最优设计应该是减小涡旋卷体的倾覆力矩。
The design of scroll compressor is discussed. Thrust bearings are the key components of scroll compressors used in air conditioning and refrigeration for long periods of time. Axial thrust and torque have an impact on the thrust bearing. The thrust load bearing condition is described using the Rumbarger theory. How to optimize the geometry of the scroll wrap is also a major concern for designers. The problem of how to optimize the geometry of a scroll wrap is considered in consideration of stable operating conditions, weight, axial thrust, and roll outer diameter. In determining the thrust bearing outer diameter size, the optimal design should be to reduce the roll lap overturning moment.
