Abstract
The invention regards a planetary gearbox which includes a sun gear, a plurality of planet gears which are driven by the sun gear, a ring gear, and a plurality of journal bearing pins. Each of the journal bearing pins is located in an inner bore of one of the planet gears, wherein the journal bearing pins each have a longitudinal axis which extends in the axial direction of the planetary gearbox. In each case a journal bearing pin and a planet gear form a journal bearing. It is provided that the journal bearing pin includes, along the length of the journal bearing, a stiffness which varies along the longitudinal axis of the pin.
