Abstract
The locking ring includes a body having an axis and a hole along the axis. The body receives a shaft in the hole. The body includes a cavity, a first passageway communicating with the cavity, and a locking mechanism for releasably locking the body to a portion of the shaft disposed in the hole. The locking ring further includes a piston member having a piston head and a piston rod connected to the piston head. The piston head is disposed in the cavity, and the piston rod projects from the cavity in a direction parallel to the axis. The piston member moves relative to the body when pressure is supplied to the cavity via the first passageway.
