1,248,981. Rack-and-pinion gearing. CAM GEARS Ltd. 5 June, 1969 [30 Aug., 1968], No. 41435/68. Heading F2Q. In a rack-and-pinion assembly for a vehicle steering gear, the pinion 1 is rotatably supported in a housing 4 by bearings 2, 3, of which the bearing 3 comprises co-operating pin-andsocket parts 9, 11, one part mounted in the housing and the other carried for rotation with the pinion 1, with the pin part 9 having a hemispherical or other axially convex bearing head profile. As shown, the socket 11 is in the pinion end face, but in Fig. 3 (not shown) the socket is in an insert (22) of the housing and the pin part (20) is integral with the pinion. The bearing 2 is axially adjustable by a nut 16 to preload the bearings. A shoe 8 of the type described in Specification 1,248,982 supports the rack bar 7 and urges the rack 6 into mesh with the pinion 1. |
