驱动轴承内嵌式涡旋压缩机特性分析

对驱动轴承内嵌于动涡旋齿中的涡旋式压缩机的几何特性进行了研究分析，引入了涡旋型线始端展角和终端展角，使吸气容积、吸气角、排气容积、排气角、内容积比等几何参数计算式的应用更为方便，它不仅适用于涡旋型线为整数圈的情况，而且也适用于涡旋型线为非整数圈的情况。将动涡旋的驱动轴承安置于涡旋齿中，可以在结构设计上达到减少气体力和动涡旋离心惯性力对动涡旋产生的倾覆力矩的目的，从而改善了驱动轴承的受力状况。延长了使用寿命。

Characteristics of Scroll Compressor with Driving Bearing Set in Orbiting Scroll

The geometric characteristics were analyzed for a scroll compressor with driving bearing set in the orbiting scroll.The final angle and the starting angle for midline of scroll wrap thickness were used for calculating the suction volume,discharge volume,build-in volume ratio,suction angle,and discharging commence angle for both integer circle number scroll compressors and non-integer circle number scroll compressors.The driving bearing was set in orbiting scroll to reduce the overturning moment caused by the gas force acted on orbiting scroll and the centrifugal force on orbiting scroll.Thus the working condition of driving bearing for acting forces can be improved.
