Abstract
A stop module halts rotation of a shaft of a rotational drive system when an axial stroke limit is reached without the use of frictional brake plates. The module has a fixed nut and a pawl carrier coaxially mounted on the shaft for axial travel along the shaft and rotation with the shaft. The pawl carrier includes a screw portion mated with the nut such that rotation of the pawl carrier with the shaft causes the pawl carrier to travel axially along the shaft. A pawl member is pivotally coupled to the pawl carrier, and a stop element is fixed at an axial limit location. The pawl carrier is axially displaceable from a non-limit position wherein the pawl member is clear of the stop element during rotation to a limit position wherein the pawl member is interfered with by the stop element during rotation to stop rotation of the shaft.
