Abstract
A variable dwell cycloidal indexing device for converting a uniform rotational motion into intermittent rotational motion with greater than one predetermined dwell point. The device includes an input shaft having an axis of rotation with a stub shaft extending eccentrically from a distal end of the input shaft. A planetary gear is rotatably mounted on the stub shaft. There is an internal gear rotatably supported on the input shaft and mounted coaxially therewith with the planetary gear intermeshing with said internal gear. A crank pin projects from the planetary gear at a position eccentric to the axis of rotation of the planetary gear. The motion of the crank pin during rotation of the input shaft is defined by allowing the crank pin to oscillate in a slide slot at a fixed location, or by attaching the crank pin to a pivoting link which is, in turn, attached to a fixed point. In either case, rotation of the planetary gear about its own axis is limited. The number of dwell points is determined by the gear ratio between the internal gear and the planetary gear.
