目前国内外广泛地使用少齿差行星齿轮减速器。其中的一齿差啮合付能在较小的空间里得到最大的速比,格外受到重视。从齿型来看,摆线针轮行星传动不仅承载能力大,效率也较高,应用得更广泛些。但是它对于材质、热处理、制造工艺的要求较高,还要用专门的机床和刀具,一般中小企业进行单件小批生产有困难,使它的进一步推广遭到障碍。渐开线一 At home and abroad widely used less tooth difference planetary gear reducer. One of the tooth gap to pay to pay in a smaller space to get the maximum speed ratio, particularly attention. From the tooth view, cycloid planetary gear drive not only carrying capacity, high efficiency, more widely used. However, it has higher requirements for materials, heat treatment and manufacturing processes, and also requires specialized machine tools and knives. In general, small and medium enterprises (SMEs) have difficulty in producing small pieces in a single piece, which makes it difficult to further promote it. Involute one
