【Abstract】 The work principle and machining principle of the stator and rotator of a new type rotate compressor named the abnormal cycloid compressor are introduced. The free-body diagram of rotator which is a key part has been constructed. an approach is established for calculating the inertia centrifugal force Sr, the force Fg due to air pressure difference of cubage cavity and the moment MFg due to Fg ; an approach is established for calculating the pressure Nf which acts on bearing through eccentric shaft, the force fn which acts on phase gear through center gear and the moment Mfy due to fn;In addition, established an approach is given for calculating the pressures N1? N2?N3 due to rotator contacting with stator. These approaches are applied to a kind of developing compressor (refrigeration power:100 000 cal/h, refrigeration medium: R22) to calculate the forces acted on rotator. Then by use of the lubricating diagram of Hooke, the minimal film thickness 0.745 μm between stator and rotator is given.更多还原
