A gear unit, comprising:
- a housing,
- a gearwheel disposed in the housing,
- characterized by further comprising a bearing assembly mounting the gearwheel in the housing, whereby the gearwheel is supported so as to be axially spring-elastic and mounted so as to be movable and pre-loaded in relation to the housing,
- wherein a first bearing assembly comprises at least one first spring module and at least one first bearing module, and the first spring module is arranged in combination with the first bearing module on each end face of the gearwheel so that a plurality of ball bearings in the at least one first bearing module roll in a raceway formed in each end face of the gearwheel,
- wherein the first spring module is specified and disposed in such a manner that the gearwheel is disposed so as to be pre-loaded in the housing
- wherein provided is at least one second bearing assembly which is designed in such a manner that the gearwheel is supported axially as well as radially and mounted so as to be movable in relation to the housing, and
- wherein the second bearing assembly for radial support comprises at least one friction bearing, and for axial support one second bearing module and one second spring module.
