1,151,799. Bearings. BROWN, BOVERI & CO. Ltd. 26 Sept., 1967 [28 Sept., 1966], No. 43775/67. Heading F2A. A thrust bearing for a rotatable shaft 1, Fig. 1, comprises an annular member 3 fixed to said shaft adjacent a non-rotatable annular member 4, which is fixed to a further annular member 5 by a plurality of radial pins 14, Fig. 3, the member 5 being coupled to a support member 7 by a gimbal that includes a ring 6 and two mutually-perpendicular pairs of pivot pins (8, 11), Fig. 2 (not shown). Lubricating fluid, e.g. a gas, is directed between the mutually adjacent surfaces of the members 3, 4 through bores 19, 20 in each of the pins 14 and bores 17, 18 in the member 4, leakage from the latter being prevented by 0-rings 15, which are resilient and thereby effect resilience in the mounting of the member 4 with respect to the gimbal. Additional resilience may be effected by providing a radial recess 21 adjacent each of the pins 14. The shaft 1 is supported by a plain bearing 2. The bearing may be modified such that the member 4 is located between two annular members (not shown) that are fixed to the shaft 1. |
