Abstract: 387,620. Tilting pad bearings. WATSON, F., 43, Southampton Buildings, London.-(Aktiebolaget Nomy ; 2, Norrmalmstorg, Stockholm.) Sept. 12, 1932, No. 25385. [Class 12 (i).] In a radial-thrust bearing in which load-supporting lubricant films are set up between spherical sliding surfaces 6, 7 on a bearing member 5 and on tiltably supported bearing blocks 2 respectively, the radii of the spheres forming the sliding surfaces of the blocks differ from the radius of the sphere forming the sliding surface of the bearing member by an amount which is less than the radial play between the surfaces with even peripheral distribution of the blocks. Preferably the difference between the radii is equal to one half the radial play between the surfaces, the other half of the desired play being produced by a relative radial displacement of the surfaces. The invention is shown applied to a bearing in which blocks 2 rotate inside a stationary member 5. The invention may be applied to bearings in which the blocks are stationary and are located either inside or outside of the bearing member co-operating therewith. Specifications 290,637 and 333,855, [both in Class 12 (i), Bearings &c.], are referred to.
