Abstract

A transmission (101) with at least one planetary carrier (102), at least one ring gear (103), at least one planetary gearwheel (105), at least one planetary bolt (107), one or more planetary bearings (109) and at least one sun gear (111). The planetary bolt (107) is fixed into the planetary carrier (102). The planetary gearwheel (105) is mounted to rotate on the planetary bolt (107) by way of the planetary bearing (109). The planetary gearwheel (105) meshes with the ring gear (103) and/or the sun gear (111). The transmission (101) includes at least one nut (123). The nut (123) screws onto an external thread (121) of the planetary bolt (107). The planetary bearings (109) are axially fixed by the nut (123) and a shoulder (125) of the planetary bolt (107).
