Loosening arrangement for fixed machine parts - has vibration provided by unbalanced rotating mass whilst applying torque and release fluid

摘要

The arrangement incorporates a grip (1) which is secured to the part (6) to be loosened e.g. by clamping with screws. An out of balance weight (2) is mounted on the grip so that it can rotate and be driven by a motor (3). When the out of balance weight is driven by the motor, the screw will be shaken. The arrangement further incorporates a supply of e.g. penetrating oil which is fed to the screw thread. The grip has a hand lever with which torque can be exerted on the screw connection.
