DEVICE FOR PREVENTING LOOSENING OF A TAIL DOG CAPABLE OF PREVENTING THE LOOSENING OF A FASTENING BOLT DUE TO INERTIA IN TIMES OF ROTATION OR STOP BY ROTATING THE HEAD AND BODY OF A FASTENING BOLT IN AN OPPOSITE DIRECTION

摘要

PURPOSE: A device for preventing loosening of a tail dog is provided to minimize the failure of angle splitting in times of finish machining of a turbine rotor by preventing a fastening bolt for a tail dog from loosening due to inertia in times of rotation or stop of an anti-loosening nut.;CONSTITUTION: A device(100) for preventing loosening of a tail dog comprises a turbine rotor(10), a tail dog(20) for finish machining, a fastening bolt(30), and a nut(40). The tail dog is assembled to the turbine rotor. The fastening bolt fixes the tail dog. The nut is coupled to the tail dog and the fastening bolt. The nut prevents the loosening of the fastening bolt due to inertia.;COPYRIGHT KIPO 2012
