Abstract
A fail-safe device for preventing undesired rotation of the output as the result of bearing failure and seizure is shown according to the teachings of the present invention in its most preferred form for use with a clutch engagable in a single driving position. In its most preferred form, the output includes a hub portion which is rotatably mounted to the input of the clutch by a bearing. The output of the clutch further includes a collar portion for receipt upon the hub portion and forming a break away connection therebetween. The driven portion of selectively rotationally interrelating members of the clutch, i.e., teeth in the preferred embodiment shown, is located on the collar portion of the output. Under normal operation and without bearing failure, the collar and hub portions of the output have the same relative rotational position and rotate as a single unit. However, in the event of bearing failure and seizure and assuming the output is not clutched in with the input, relative rotation is allowed between the hub portion and the collar portion of the output to prevent undesired rotation of the machinery or other apparatus connected to the output of the clutch.
