Abstract
789,958. Supporting bearings. GENERAL MOTORS CORPORATION. Oct. 22, 1956 [Oct. 24, 1955], No. 32068/56. Class 12 (1). A gas turbine rotor bearing 19 is supported with respect to casing 16 by a spider having radiating arms 27, a telescopic connection between each arm and the casing being provided to permit relative sliding in the radial direction and each connection including spring means biasing the arm radially with respect to the axis so as to resist radial movement of the spider with respect to the axis. As shown in Figs. 1 and 2 the connection comprises a bolt 31 threaded in a stiffening ring 32, welded to the casing, and including a pin 33 adapted to slide in a ring 28 secured to the end of the strut 27. Oppositely disposed coned washers 36 are disposed on the pin 33 between the ring 28 and a shoulder on the bolt 31. Adjustment of the spring pressure is effected by inserting a, shim 37 under the head of the bolt. In a modification, a hollow stud 41 is locked in position by a nut 42, Fig. 3, and only one set of washers 43 is provided. In another modification, a stud 52 is screwed into a ring 51 attached to the end of the arm 27 and a cylindrical portion of the stud is adapted to slide in a hard bushing 53 fitted in a ring 56 secured to the casing. In a further modification, ring springs 62, 63, Fig. 5, are used, which may be made of materials having different coefficients of expansion to compensate for greater radial expansion of the spider than the casing.
