摘要： PURPOSE:To obtain a rotary machine hanger, where an excessive bending moment is made not generating in its hanging beam, by fixing a hanging board to the side of the hanging beam through a saw tooth shape engagement portion and by making a coupling with a link between the hanging board and the rotor. CONSTITUTION:An auxiliary beam 11 is installed to a hanging beam 4, which is hung by a plurality of hanging hooks 5, at a symmetrical position with respect to the center of a rotor 1 and farther inside from said hanging hooks 5. A distance between the both sides of said auxiliary beam 11 is equal to an interval of hanging position between radial spokes of the web 12 of the rotor 1, accordingly with the above both sides being in parallel to the outside of the facing web 12. To the both sides of said auxiliary beam 11 is installed to be fixed a hanging board 13 through an engagement portion 15, 16 of saw tooth shape, and in the bottom end of said hanging board 13 is rotatably provided a link 19, with its top end coupled further with its bottom end bearing-supported by the web 12 of the rotor 1. Accordingly, the hanger can be provided with an excessive bending moment never being caused in the hanging beam 4.

摘要： PURPOSE:To prevent the production of cruel thermal stress on brake ring, by increasing the pressing force of brake in accordance with the dripping of rotation. CONSTITUTION:A plurality of air supply tubes 9A, 9B are connected in parallel with air tank 10. Electromagnetic valves 14A, 14B for regulating the supply of compressed air are provided to each air supply tubes 9A, 9B. Predetermined number of brakes 6A, 6B are connected to said air supply tubes 9A, 9B, then said electromagnetic valves 14A, 14B are sequentially opened in accordance with the drop of rotation to function the brakes 6A, 6B in step thus to increase the pressing force of brake. Consequently the brake ring is prevented from producing cruel thermal stress.
