Abstract

601,547. Bearings. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and COWAN, H. Oct. 3, 1945, No. 25765. [Class 12 (i)] A shaft bearing arrangement comprises a plurality of bearing elements each mounted in one of a plurality of nested coaxial sleeves with each sleeve engaging at one end against a closely confined pad of resilient material whereby the bearing elements share the axial thrust load in predetermined proportions. The bearing arrangement shown comprises two ballbearings 4, 5 each carried in a sleeve 6, 7 extending axially to engage against a rubber ring 10 wholly filling an annular space formed by a co-operating end plate 16 which is secured, together with a housing 11 for the complete bearing arrangement, by bolts to the frame or other support 12. The rubber ring in effect sets up a uniform pressure so that the end thrust taken by each bearing is proportional to the end area of the sleeve or to the end area of an interposed ring 9 as in the case of bearing 5 and its sleeve 7. The radial thrust is taken wholly by the bearing 4 since its sleeve 6 at the region of the bearing engages against the housing 11 whereas sleeve 7 is freely movable radially as it is radially spaced from sleeve 6 and the housing 11. The radial load may be divided in predetermined proportion by having the sleeve 7 engage the sleeve 6 at the region of the bearing 5, the proportion being then determined by the elasticity characteristic of the sleeve 6 which at this region is slightly spaced from the housing 11. For ensuring that the rubber ring wholly fills the annular space, the end plate is spaced by suitable shims 14.
