1,116,873. Bearings. TORRINGTON CO. 15 June, 1965 [22 June, 1964], No. 25156/65. Heading F2A. A multiple row taper roller bearing assembly on a tapered shaft embraced by a backing ring 16, comprises series of taper rollers in inner and outer races, locking means 45, 47 between the bearing and an inner stop ring 15 in a groove in the shaft, and a jack 51 actuable between the bearing and an outer stop ring 50 in a groove in the shaft. The ram of the jack is extended by oil or air pressure and acts through ring 46 on the inner races, forcing them up the shaft into engagement with ring 16. Nut 47 is then unscrewed to abut ring 15, and a stud (42, Fig. 3, not shown) inserted in groove 59 and a hole in ring 45, thus locking the bearing in position. Ring 50 and jack 51 are then removed. |
