    摘要： 1,106,584. Bearings; shaft seals. TIMKEN ROLLER BEARING CO. 2 Sept., 1966 [28 Feb., 1966], No. 39449/66. Headings F2A and F2B. A shaft bearing seal comprises a casing 27 having large, intermediate and small diameter walls 28, 30 and 32 respectively, the wall 30 being connected to the walls 28 and 32 by radial walls 29 and 31 respectively and the wall 32 terminating in an inwardly directed flange 33, shaft sealing means 34 being provided adjacent the flange 33 and extending axially therefrom a distance less than the length of the wall 32 so that the flange 31 provides an abutment for a seal removal tool T thereby permitting removal of the casing from the bearing without damaging the sealing means 34. As shown in Fig. I, a seal according to the invention is applied at each end of a roller bearing assembly for an axle journal 9, the seal casings 26 and 27 being mounted in the ends 24 and 25 of the outer bearing roll 23. The sealing means 34 comprises a sealing ring 38 bonded to a ring 35 and having two sealing lips 41 and 42, the latter being urged inwardly by a garter spring 43. A retainer ring 44 is held within the ring 35 by a rolled-over edge portion 35a of the ring 35. In a modification, Fig. 3 (not shown), the ring 35 is omitted and the sealing ring (38) is bonded to a lip (33a) of the flange (33). In a further .modification, Fig. 5 (not shown), the garter spring (43) is moulded into the sealing ring (38a).
