摘要 齿轮-平行四边形机构是一种具有特殊运动性能的齿轮连杆组合机构。介绍了该机构的组成规则,并对外啮合式和其带惰轮式组合机构进行了分析。同时,在分析了内啮合式组合机构的传动性能后,根据同性异构原理,对其进行了演化与变异,经过内、外啮合组合机构的比较,对如何改变不同形式组合机构的传动比进行了总结,并从中找到了一种传动比大、机械效率高、尺寸小、质量轻、结构紧凑和运动平稳性较好的内啮合内平动式组合机构。为设计新型减、增速器组合机构提供了一定的理论依据。 The gear - parallelogram mechanism (GPM) is a kind of geared linkage combinative mechanism with special motion performance. The composition rules of GPM are introduced, and the transmission property of outer teething type and idle gear type of GPM are analyzed. Meanwhile, according to the principle of the variation of the isomorphism, the evolution and mutation of internal teething type is studied. By the comparison of internal and external meshing combined mechanism, the method of changing different mechanism trans- mission ratio is summarized and the type of internal teething and internal parallel motion of GPM is chosen, which has large transmission ratio, high mechanical efficiency, small size, light weight, compact structure and better smoothness of moving. Some theoretical basis for design new combined mechanism about reducer and speed increaser is provided.
