基于变胞原理提出一种转子与气缸分离、以平面变胞间歇机构实现周期性配气的微容积式机器。首先,采用型综合的方法设计具有间歇运动的平面变胞机构,进而根据该变胞机构设计出了微容积式机器的整体方案,并得到表示各构态下变胞副运动状态的变胞机构运动循环表和等效阻力梯度线图;最后对平面变胞机构关键部件及容腔运动规律进行仿真分析。研究设计表明,基于变胞原理的容积式机器结构简单、动态特性好,为提高容积式机器的综合性能提供了一种新的途径。

It is based on the principles of the metamorphic to put forward the micro-displacement machine whose rotor isolates from the cylinder and it uses the mechanism of the plane metamorphic-intermittent to distribution gas periodicity. First, designing the plane metamorphic mechanism which can achieve the intermittent motion by type comprehensive; then designing the overall program of the micro-displacement machine based on it, and obtaining the plane metamorphic mechanism＇s motion cycle table and equivalent resistance gradient chart to represent the state of motion for each configuration; finally conducting the simulation of the plane intermittent mechanism about the key component and the movement of the plenum. The study shows that the micro-displacement machine which is based on the principles of the metamorphic has simple structure and good dynamic characteristics, and provides a new way for increasing the comprehensive performance of the displacement machine.
