Claim 18:
19. A planetary gear box, comprising:
a sun gear, which rotates about an axis of rotation of the planetary gear box and is driven by a sun shaft, wherein the axis of rotation defines an axial direction of the planetary gear box,
a plurality of planet gears, which are driven by the sun gear,
a ring gear in engagement with the plurality of planet gears,
a plurality of planet pins, each arranged in one of the planet gears, respectively, with each planet pin and planet gear arrangement forming a bearing, and
an axially forward carrier plate and an axially rearward carrier plate, wherein each of the planet pins is fixed at an axially forward end thereof on the axially forward carrier plate and at an axially rearward end thereof on the axially rearward carrier plate,
wherein each of the planet pins is of two-part configuration, having a radially outer pin part and a radially inner pin part, which are connected to one another in a manner precluding relative rotation therebetween, wherein the radially outer pin part forms the bearing with the planet gear, and only the radially inner pin part is fixed at its axially forward end and axially rearward end to the axially forward and axially rearward carrier plates, respectively,
at least one radially extending web rotationally fixedly connecting the radially inner pin part and the radially outer pin part,
wherein the at least one radially extending web is formed monolithically with the radially inner pin part,
wherein the at least one radially extending web radially spaces apart the radially inner pin part and the radially outer pin part such that there is an axially extending gap therebetween axially extending over a majority of an axial length of the radially outer pin part.
