Abstract: A slip clutch includes a driven member, a spring, at least one friction plate interfacing with the driven member and an adjustment nut. The friction plate is pressed against the driven member through the combination of the spring and adjustment nut. The adjustment nut has multiple lobes and profiled surfaces between the lobes having a smaller radius from the axis of rotation of the clutch than the lobes. A hub extends along the axis through the driven member, spring, friction plate, and adjustment nut. The adjustment nut is rotationally fixed with respect to the hub and has a reduced profile to improve airflow to other components of the slip clutch.

Abstract: A coupling transmits torque between two shafts approximately aligned on a shaft axis. The coupling has a center axis approximately aligned with the shaft axis. The coupling comprises arcuate coupling segments with ends extending generally parallel to the coupling center axis and arcuate portions extending between the ends. The arcuate coupling segments are arranged in a ring with adjacent segments being arranged end to end to form the coupling. Each coupling portion comprises a first clamp ring adapted to be operatively attached to a shaft and a second clamp ring adapted to be operatively connected to another shaft. Elastomer material extends between both clamp rings. The elastomer material extends axially and circumferentially on each clamp ring in areas adjacent to each end of the arcuate coupling segment.
