Abstract:
A spur gear differential (1) having a first sun (3) and a second sun (5), wherein the first sun (3) is associated with a first set of planetary gears (7) and the second sun (5) is associated with a second set of planetary gears (9), and the first set of planetary gears (7) engages with the second set of planetary gears (9). The number of teeth (11) of the first sun (3) are equal to the number of teeth (12) of the second sun (5), and the teeth (11) of the first sun (3) are disposed by a profile shift on a crown circle (2) having a crown circle diameter (DK1) that differs from the crown circle diameter (DK2) of a crown circle on which the teeth (12) of the second sun (5) are disposed. The first set of planetary gears (7) engages only with the first sun (3) and the second set of planetary gears (9) engages only with the second sun (5).
