Abstract

A transmission includes a shaft, a housing part and an adapter housing, the housing part and the adapter housing being connected. A first bearing for mounting the shaft is accommodated in the adapter housing, and a second bearing for mounting the shaft is accommodated in the housing part. A space region is situated in the housing part, which is at least partially filled with lubricating oil and is limited by and/or sealed from the adapter housing with the aid of at least one first shaft sealing ring. On the side of the first shaft sealing ring facing away from the space region, in particular on the side of the first sealing ring axially facing away from the space region, a sealing ring is situated on the shaft, which is connected to the shaft in a torsionally fixed manner, in particular pressed and/or slipped onto the shaft, the sealing ring at least partially projects into a recess of the adapter housing, the recess including a circumferential depression, which is limited by a wall region of the adapter housing in the direction of the shaft, the sealing ring touches the wall region or radially projects from the wall region, in particular such that lubricating oil that axially flow…
