Abstract

719,194. Self-aligning bearings. COMERY, P. D. Jan. 29, 1953 [Feb. 1, 1952], No. 2603/53. Class 12(1) A self-aligning bearing arrangement comprises a shaft 10, Fig. 1, mounted in bearings 11 supported in a housing 14 provided with a flange 15 the outer surface 16 of which is curved with a radius R. An element 19 positioned between thrust surfaces 15a and 20a is confined against radial expansion by the machine frame 18, and comprises a series of wedge-shaped blocks 30, 31 in interengagement as shown to provide the selfaligning action. The blocks are loosely threaded in the manner of beads on a bracelet on a double wire 32, so that when they are moved axially relatively to one another from the Fig. 1 position, the circumference of their circumscribing circle is increased. Springs 25 around the bearing are supported by the flange 15 and closure plate 23 and are provided to keep the flange 15 and shoulder 20 in contact with the element 19 under conditions of slight reverse thrust. In operation, thrust is transmitted from the shaft 10 directly through the bearings 11 to the housing 14 and thence through the flange 15 and the element 19 to the machine frame 18. Under the influence of the load each block of the element is urged, like a wedge, between the inclined lateral faces of adjacent blocks, thereby tending to increase the circumferential length of the element. However, the wall 17a of the recess 17 confines the element against radial expansion. Any small mis-alignment of the shaft is absorbed by deformation of the element 19, the clearances 42 and 43 on one side of the assembly being reduced while the corresponding clearances on the diametrically opposite side of the assembly are increased, by a sliding action between the faces 40, 41, of adjacent blocks and a circumferential displacement progressively from block to block around the element. It is desirable that adjacent blocks should be made of dissimilar materials, such as bronze and steel, as a precaution against seizing. Specification 659,526 is referred to.
