Abstract
550,457. Differential gearing. FELLOWS GEAR SHAPER CO. Sept. 11, 1941, No. 11669. Convention date, Nov. 20, 1940. [Class 80 (ii)] In a differential gear, the teeth of one or both sun gears, or of the engaging planetary gears, are formed with variable pitching so that should one of the sun gears be held stationary the other sun gear is driven with recurrent impulses the reaction of which acts on the first sun wheel and tends to rotate it. As shown in Fig. 6 in which sun wheels 161, 171 are in developed form, the pitch of the teeth of the planetary pinion 181 is variable, increasing from a minimum between the teeth t', t', in both directions round the pinion to a maximum at the diametrically opposite teeth t<SP>9</SP>, t'‹. The tooth pitch on the suns 161, 171, is uniform, the two suns being identical to one another. In a modification the pitching of the teeth of the planetary gears is uniform, the tooth spacing round the sun gears being variable. The invention is applicable to differentials embodying face sun gears with spur reacting pinions, or tapered or bevelled gears and pinions, or differentials with a single planetary pinion or with helically toothed gears and pinions. In the form shown in Fig. 1 the suns 16, 17 are face gears which mesh with planetary spur pinion 18 carried by a spider 19 secured to a divided casing 21 fixed to a driving bevel wheel 13.
