Abstract

984,497. Bearings; lubricating. ROLLSROYCE Ltd. Oct. 15, 1963 [Jan. 9, 1963; April 4, 1963], Nos. 40552/63 and 40553/63. Divided out of 961,522. Heading F2A. [Also in Division F1] A bearing assembly comprises a fixed annular outer race, a rotatable annular inner race which is mounted concentrically within the outer race and is spaced therefrom by rolling elements which are in rolling contact with the inner and outer races, rotatable shafting which is mounted in and secured to the inner race, an annular member which is mounted securely within the shafting and which is provided with a number of angularly spaced-apart pockets each of which communicates with the inner circumferential surface of the annular member, means for supplying the inner circumferential surface with lubricant, and lubricant passages which are formed in said shafting and inner race and which lead from at least some of the pockets to the rolling elements, at least the said same pockets being formed so that, in operation, they both retain a quantity of lubricant therein and also direct a supply of lubricant into the lubricant passages and so to the rolling elements. The subjectmatter repeats that of Specification 961,522 but in addition, as shown in Figs. 6 and 7, there is a modification in which an annular member 91b has pockets 92b therein, each of which has a wall 126 over which lubricant flows and which prevents reverse flow of lubricant from the pocket. Each pocket 92b has also a radially outwardly extending surface 127 over which lubricant is centrifugally forced in passing into a respective drilling 93b.
