Abstract
A planetary gear has two axially adjacent ring gears (11, 12), several planet wheels (10) mounted inside a planet carrier (2) so as to rotate and a central sun wheel (1). Between two planet wheels (10) is provided each time an intermediate shaft (6) and each shaft has two sets of teeth (7, 8), the smaller set of teeth (8) being provided for simultaneous engagement with two adjacent planet wheels (10) between which the intermediate shaft (6) is situated, and the second set of teeth (7), the reference circle of which is larger than that of the first one, engages with the central sun wheel (1).
