Mechanical Property of Internal Meshing Rotary Compressor

Abstract

The internal-meshing rotary mechanism is widely used in the oil pumps and cyclonical pin wheels application. The working principle of the internal meshing rotary compressor is very different with the current institutions applications. while, the mechanical property method of the internal meshing rotary pump can’t be entirely and directly used in the rotary compressor because of the different working principles. In order to simplify the study of the internal-meshing rotary compressors, the forces acted on the inner and outer gears are computed. The gas force and torque related to the rotating angle are derived, and then compared with other rotary compressors. The result shows that the internal meshing rotary compressor’s mechanical parameters vary periodically and the period is 2π/Z2and this type of compressor has perfect mechanical property compared with other compressors.
