Zusammenfassung:	A gear differential having multiple gear trains interconnecting a pair of output shafts is provided with an arrangement of gearing having an expanded relationship between tooth numbers of the gearing for fitting the gear trains into mesh. The gearing includes two side gears (20 and 21) coupled to respective output shafts and three pairs of combination gears (24 and 25, 26 and 27, and 28 and 29) for interconnecting the two side gears. Each of the combination gears includes a middle gear portion (40) and two end gear portions (42 and 44). The middle and end gear portions have respective numbers of teeth that share a greatest common factor (GCF) that is more than one but less than the number of teeth in the middle gear portion. Un différentiel d'engrenage possédant des trains d'engrenage multiples reliant une paire d'arbres de sortie est pourvu d'un ensemble d'engrenage présentant une relation espacée entre les nombres de dents dudit ensemble, de façon à mettre en prise les trains d'engrenage. L'ensemble d'engrenage comporte deux engrenages latéraux (20 et 21) accouplés aux arbres de sortie respectifs et trois paires d'engrenages combinés (24 et 25, 26 et 27, 28 et 29) servant à mettre en prise les deux engrenages latéraux. Chacun des engrenages combinés comprend une partie d'engrenage médiane (40) et deux parties d'engrenage d'extrémité (42 et 44). Les parties d'engrenage médianes et les parties d'engrenage d'extrémité possèdent des nombres respectifs de dents partageant le plus grand facteur commun supérieur à un mais inférieur au nombre de dents de la partie d'engrenage médiane.
