The transmission has an outer case fitted with a ring gear (3) having internal teeth, and an outlet planet carrier (4) comprising planet gears (2a, 2b) meshing with the ring gear and a sun gear (1). The case has an inlet bearing (16) and two roller bearings (9a, 9b) forming an outlet bearing. An outlet unit (10) is coupled to rotate with the carrier and co-operates with the carrier to form a unit for preloading the outlet bearing. An independent claim is also included for a set of transmissions of three sizes, for a given gear ratio.
