ABSTRACT:
A quick release mechanism having a lifting ring (34) and a support ring (30) generally surrounds a shaft to be clamped (20). A cam or other lifting mechanism(32), operated by a handle (42), acts to separate the support ring and the lifting ring in a direction in line with the shaft. A restraint and adjustment nut(40) mounted on the end of the shaft in contact with the lifting ring acts to tension the shaft. The lifting mechanism is free to rotate about the shaft independently of the restraint and adjusting nut allowing the handle to be used in any orientation desired and preventing the handle from being used as a crank or wrench. Embodiments are provided allowing retrofit to existing shaft fastening applications, including those where access to the interior of the shaft must be maintained.
