Claim 17:
18. A method for assembling a planetary gear box, comprising:
providing that the planetary gear box comprises:
a sun gear, which is driven by a sun shaft,
a plurality of planet gears, which are driven by the sun gear, wherein each of the planet gears has an inner axial opening,
a ring gear in engagement with the plurality of planet gears,
a plurality of planet pins, with each being of two-part configuration having a radially outer pin part and a radially inner pin part,
an axially forward carrier plate and an axially rearward carrier plate, wherein each of the planet pins is fixed at an axially forward end on the axially forward carrier plate and at an axially rearward end on the axially rearward carrier plate of the planetary gear box,
wherein axial forward and axially rearward ends of the radially outer pin part are connected respectively to the axially forward and axially rearward carrier plates to prevent relative rotation therebetween,
for each of the planet pins:
introducing the radially outer pin part into the inner axial opening of a respective one of the planet gears,
positioning the respective one of the planet gears between the axially forward carrier plate and the axially rearward carrier plate in the planetary gear box,
introducing the radially inner pin part into the radially outer pin part and fixing axially forward and axially rearward ends of the radially inner pin part respectively to the axially forward and axially rearward carrier plates.
