摘　　要：对驱动轴承内嵌式双涡旋齿涡旋压缩机建立了吸气容积、排气容积、压缩比的计算公式;对作用于双涡旋齿动涡盘的气体力建立了分析模型.计算结果表明:驱动轴承内嵌式双涡旋齿涡旋压缩机相对于传统的双涡旋齿涡旋压缩机,切向、轴向和径向气体力均减小;相对于驱动轴承内嵌式单涡旋齿涡旋压缩机,波动幅度小,运行更平稳,更适合于压缩比小、输气量大的场合.Calculating formulae of suction volume,discharge volume,pressure ratio are worked out for twin-wrap scroll compressor with driving bearing set in orbiting scroll.An analyzing model for gas forces of dynamic eddy of twin-wrap is examined.The result shows that the force gases of tangential direction,axial direction and radial direction are reduced with minor fluctuation,in comparison with those of the traditional twin-wrap scroll compressor;it runs more stable,especially in the conditions of lower pressure ratio and larger displacement volume.
