摘要：A disconnectable locking system or arrangement between a rotor hub and pump shaft of a roto-dynamic pump when a shaft portion is inserted into a bore of the hub, including a locking sleeve on the shaft adapted to be moved by the action of a threaded nut so as to have one end thereof extend into the hub bore until a thrust shoulder on the sleeve engages the hub, the end of the sleeve being chamfered and adapted to contact a first split ring positioned in a recess in the hub bore so as to in turn contact a second split ring fastened to the shaft and forming a thrust surface with said first split ring.
