本文介绍作者研制出的双层滑片压缩机，这种压缩机的每个滑片槽内都安放两块重叠而又可以相对自由滑动的滑片。利用建立的动力学模型对双层滑片压缩机的运动、受力、摩擦、磨损及强度等进行了全面分析，结果表明双层滑片结构能够减少正约束力的幅值，降低摩擦损失和磨损量；但使滑片应力有所增加，强度有所降低。上层滑片与下层滑片的厚度比是双层滑片压缩机的重要结构参数，通过对不同厚度比的双层滑片结构的受力状况、摩擦磨损及强度的分析比较，找出了厚度比的适宜值。
This article describes the double-layer vane compressor developed by the author. Each vane slot in such a compressor accommodates two overlapping and relatively free-sliding vanes. The kinetic model was used to comprehensively analyze the movement, force, friction, wear and strength of the double-slide compressor. The results show that the double-slide structure can reduce the amplitude of the positive restraining force and reduce the friction loss Wear; but to slide the stress has increased, the intensity decreased. The thickness ratio of the upper vane to the lower vane is an important structural parameter of the double vane compressor. By comparing and analyzing the stress, friction and wear and strength of the double vane with different thickness ratios, the thickness Than the appropriate value.
