<p>Each bearing has a cup (30) on one of the seats of the housing (2), a cone on the surrounding seat (50) of the carrier (8) and tapered rollers organized in a single row between tapered raceways (38, 40) on the cup and cone. The bearings are in the indirect configuration so that the small ends of the tapered rollers are presented toward the interior of the housing. Moreover, the raceways of the cups are proportioned to balance axial and radial expansions. To assemble the differential, the two bearings are installed over their bearing seats on the carrier. The distance (a) between the back faces (36) of the cups is measured, as is the distance (b) between shoulders (24) at the ends of the seats in the housing. The carrier is installed in the housing with the cups of its bearings in the bearing seats of the housing. After bringing the ring gear against the pinion, the cone of the one bearing is advanced over its seat on the carrier a distance Δc which imparts the proper mesh to the ring gear and pinions. The cone of the other bearing is advanced over its seat a distance amounting to a - b - Δc + p, where p is the setting desired for the bearings.</p> |
