Abstract
A disconnect mechanism is provided which, upon a suitable trigger event, such as excess temperature causes a camming elementhaving a tapered headto move under the urging of a compression springsuch that the tapered headbecomes trapped between a rotating elementand a support. This gives rise to frictional inter-engagement which prevents further rotation of the rotating elementand thereby locks the rotating machine against further rotation. This is turn causes the shear region to fail thereby drivingly disconnecting the machine from its prime mover.
