采用轴向利径向密封的涡旋式压缩机,它的效率与其它回转式压缩机和往复式压缩机相比是有竞争力的,其轴承的载荷及转矩变化是平缓的,故可实现稳态运转,因此该机特别适用于空调机中。作者研究了园渐开线的涡旋式压缩机,计算了工作容积,並假定为等熵或多变压缩过程而得到轴向,切向,径向压力分量,对涡旋转子和十字联轴节建立了运动方程,用解析法解这些方程,计算了涡旋转子和十字联轴节的运动。涡旋转子会受到十字联轴节惯性力的影响,径向密封力是随回转频率的倍频而变化的,本文估算了作用在涡旋转子上的倾覆力矩。並阐明了涡旋转子的稳定性。 The use of axial and radial seal of the scroll compressor, its efficiency and other rotary compressors and reciprocating compressors is competitive, the bearing load and torque changes are gentle, it can be Achieve steady-state operation, so the machine is particularly suitable for air conditioners. The author studied the involvo involvo scroll compressor, calculated the working volume, and assumed the isentropic or variable compression process to obtain axial, tangential and radial pressure components, the vortex rotor and the cross shaft Section established the equation of motion, solved these equations analytically, and calculated the movement of the vortex rotor and the Oldham coupling. The vortex rotor will be affected by the inertial force of the Oldham coupling, and the radial sealing force will vary with the frequency of the rotation frequency. This paper estimates the overturning moment acting on the vortex rotor. The stability of the vortex rotor is clarified.
