378,713. Tilting-pad bearings. AKTIEBOLAGET NOMY, 2, Norrmalmstorg, Stockholm. Nov. 4, 1931, No. 30573. Convention date, Nov. 4, 1930. [Class 12 (i).] Relates to bearings of the type provided with bearing blocks 3 rotating with a supporting member 2 and adapted for limited peripheral displacement relatively to the member 2 so as to take up a tilted position upon one or other of two peripherally spaced surfaces formed on the supporting member 2 according to the direction of rotation to provide wedgeshaped oil films between the blocks 3 and a bearing race 14, some or all of the blocks 3 being free to be displaced peripherally as aforesaid independently of the others. According to the invention members are arranged to co-operate with the blocks to prevent undesired peripheral displacement of the blocks due to their own weight during their rotation. As shown in Figs. 1 and 3, opposite blocks, e.g. 5, 9, are connected by divided rings 17 accommodated in grooves 18 in the member 2. The grooves 18 may be formed in the race 14 and the rings 17 may be in one piece. In a modification, the members 17 are located in circumferential grooves formed in ribs at the centre portion of the member 2. As shown in Fig. 11, the member 2 has fixed thereto resilient members 24 which frictionally engage the blocks 3 to prevent undesired displacement thereof. In a modification the members 24, Fig. 12, setting up the frictional forces are mounted on the race 14 and are pulled together by springs 29. The members 24 may be in segments. In another modification some but not all of the blocks 3 are interconnected in dovetail arrangement.
