摘　　要：为了解决压缩机摩擦能量损失大和结构磨损严重的问题,提出了一种全新结构的平动回转式压缩机,它由固定的气缸、摆动的滑板和平动的转子等组成。由气缸的内表面、滑板和转子的外表面形成的工作腔在工作循环中进行连续的进气、压缩及排气动作,使压缩机工作状态极为平稳。介绍了该压缩机的工作原理、结构特点及几何理论,并详细推导了行程容积、气腔压力及热力学计算的有关公式。分析结果表明,该压缩机结构简单、无易损件、易于密封、摩擦磨损小、成本低,适用于各种流体。This paper presented a new frame rotary type compressor, named translational rotary compressor to overcome the large friction energy loss and the sever wear of structure of other compressor.The compressor was made up of fixed cylinder,swing vane and translational rotor.During the whole cycle,the procedure of inflow,compress,air discharge operated continuously in the working chamber formed by the inside surface of cylinder,vane and the outside surface of bladed rotor.Thereby,the working state is smooth.The operation principles,structure characteristics and geometric theory of this mechanism were formulated and analyzed,and the calculation formulae for displacement volume,chamber pressure and thermodynamic properties were deduced. The analysis results show that this mechanism is of simple structure,no wearing parts,easily airtight,slight friction and lower cost;and fits for various fluids.
