Abstract
A shaft lock assembly has a stator and a plurality of radially disposed, reciprocating lock vanes that are moved on the stator to lock and release a shaft. The vanes are held in their locked position by a rotatable cam ring. A rotatable cam scroll lifts the vanes from their locked position and positions the vanes in their released position. The vanes and shaft have coacting surfaces to produce a regenerative separating force on the vanes from a locked shaft which is under torque as the shaft is unlocked.
