蜗秆凸轮机构是一种新型的间歇运动机构。它的主要特点是能够实现仟意规律的停歇运动,具有良好的动力学特性,可广泛地应用在各种高速的轻工、冲压、电工等自动化机械中。在国外,它的最高分度转速可达1600r·p·m,并已将这种机构做为产品销售于世界各国。目前,国内已开始使用,但尚限于较低的转速。蜗秆凸轮机构的形式有两种:一种是 Snail stem cam mechanism is a new type of intermittent movement mechanism. Its main feature is able to achieve the law of intermittent motion, with good dynamic characteristics, can be widely used in various high-speed light, stamping, electrical and other automated machinery. Abroad, its highest indexing speed up to 1600 r · p · m, and has this mechanism as a product sold in all countries in the world. At present, China has begun to use, but still limited to lower speed. There are two types of worm-stalk cam mechanisms: one is
