文摘：The KHV indexing cam mechanism is a new type intermittent mechanism that has a structure similar to the KHV planetary gear transmission (one type of the planetary drive with small teeth difference, where K indicates the sun gear, H indicates the pivoted arm, and V indicates the output mechanism). This paper focuses on the generation of a pitch curve and a cam profile in such a new mechanism. Three types of the KHV indexing cam mechanism are compared and discussed, and the equations of cam's pitch curves are derived. The cam's profile is generated by Boolean operations on the offsets of the cam's pitch curve. After this, the cusps on the cam profile are eliminated and replaced by a particular Hermite curve. The animations of all three types are illustrated, and a prototype of such mechanism is reported.
