<p>1,099,717. Differential gearing. ILLINOIS TOOL WORKS Inc. April 29, 1965 [April 30. 1964], No. 18143/65. Heading F2D. A differential gear comprises a crown-wheel housing 34a formed with a series of longitudinal bores serving as the sole supports for two circumferential sets of spur or helical pinions 96a, 98a, the inner peripheries of which mesh with side gears 54a, 62a formed at the ends of the half shafts 26a, 28a, the pinions overlapping axially so that the individual pinions of each set mesh with two pinions of the other set, Fig. 15 (not shown). Longitudinal bores 110a, 112a in the housing 34a and 120, 122 in the pinions permit the passage of lubricant through the gear. In an alternative arrangement, Figs. 8-13 (not shown), the longitudinal bores for the pinions are provided in a separate central member 34 (Fig. 13), while the half shafts are connected by splines 44, 46, (Fig. 9), to members 30, 32 in turn connected to internally toothed ring side gears 52, 60, meshing with the exterior peripheries of pinion sets 96, 98, the housing components being secured by longitudinal bolts 69.</p> |
