Geometric Relationship of New Type of Internal Meshing Rotary Compressor

Current applications of internal-meshing rotary mechanisms in other fields are introduced to analyze the possibility and the advantage of the internal-meshing rotary compressor.The analysis reveales that the compressor can sustain the high pressure and the high pressure difference,and has the advantages of no unbalanced mass,large swept volume,easy manufacture and so on.Adopting the inside short frame outer cycloid as the profile of the inner rotor and multi-segment arcs as the profile of the outer rotor,the essential geometric relationship of this compressor is studied including the generation of the profiles,the basic meshing properties of gears,the position of the pitch point,the radius of the pitch circles,the valid meshing range of the tooth head arc and so on.The geometric relationship establishes the fundament for the practical application of the compressor.
