Apparatus for securing a wheel to a rotatable shaft of a turbomachine

摘要

A wheel of a turbomachine is secured to a shaft of the machine by initially securing the wheel between one end of the shaft and a piston-like member. A space is formed between opposed sides of the member and wheel by moving the member relative to the wheel. A spacing member is placed in the space for placing a compressive force on the wheel for positively securing the wheel to the shaft.
