摘要
提出了一种适合高压差CO2制冷压缩机使用的内啮合转子机构,以短幅外摆线的外等距线为内转子,多段圆弧型线为外转子,建立了转子的型线方程;讨论了内外转子的基本啮合关系、瞬心的位置以及外转子齿顶圆的啮合范围等。这些基本几何关系的分析可为这种结构压缩机的使用打下一定的理论基础。
A type of internal - meshing rotary mechanism which could endure high pressure difference and be applied in CO2 refrigerating compressor is proposed. The profiles＇equations are derived from the inside short frame outer cycloid and multi - segment arc. The essential meshing relationship, position of instantaneous center and the meshing range of the tooth head arc are discussed. Those basic geometric relationships could be the foundation for the application of the compressor.
