Abstract

A planetary type gear unit comprising a planet carrier with a planet bogie plate and at least one planet shaft, whereby on both sides of the bogie plate a planet wheel is mounted on the planet shaft by taper roller bearings, whereby the planet shaft is provided with an axially displaceable piece on each of its extremities forming an abutment which provides an axial support for the inner bearing rings of the taper roller bearings and with a tensioning elements by which the axially displaceable pieces can be displaced to one another for controlling the pre-tensioning on the taper roller bearings.
