Abstract
An intermittent reversible indexing system having a rotary input and a rotary output with variable kinematic characteristics including an epicycloidal drive with dwell characteristics. A planetary carrier carrying a single planetary gear is driven about a first axis with the planetary gear in mesh with a stationary reaction gear concentric about said first axis. A drive member in the form of a shaft eccentric to the axis of the planetary engages and slides in a slot of an output member, thereby driving an output member about a second axis displaced from said first axis. The reaction gear is mounted for oscillation and a mechanism for oscillating the reaction gear is driven by an input power means which also drives the planetary carrier. A crank and lever mechanism or a simple cam mechanism can be used to oscillate the reaction gear in response to the input power means.
