Abstract
A balancing arrangement for rotating machinery has a pressure lock permitting access to the rotor without disturbing a pressurized rotor housing. The pressure lock is carried on a cover of the housing by threads which permit an inward movement of the pressure lock. A sealing cover which is provided on the pressure lock isolates the housing from the atmosphere when the rotor operates. A safety hood protects the pressure lock during operation of the machinery. Balancing of the rotor is accomplished by moving the lock against the rotor and removing the sealing cover, thereby permitting access to balancing weights in the rotor.
