TRANSMISSION DEVICE AND OIL GUIDANCE STRUCTURE PROVIDED THEREIN
First Claim
1. A transmission device comprising:
- a transmission housing which has a bottom region and a first and second side wall region,a gear set accommodated in the transmission housing and having a first gearwheel which is rotatable about a first gearwheel axis, anda second gearwheel which engages the first gearwheel and is rotatable about a second gearwheel axis, which extends parallel to the first gearwheel axis,wherein,in a side region of the first gearwheel, there is an oil guidance structure, which is formed as a component produced separately from the transmission housing,the oil guidance structure comprises a first orifice segment, which extends at least partially around the first gearwheel axis and, in doing so, forms a first side face facing the first gearwheel,the first orifice segment is bounded by an inner rim and an outer rim,a distance between the inner rim of the first orifice segment and the first gearwheel axis is smaller than a radius of an inner diameter of the first gearwheel, andthe oil guidance structure is arranged in such a way that an intermediate space remains between the first gearwheel and the first side face of the first orifice segment, said first side face facing the first gearwheel.

Abstract
A transmission device is provided having a transmission housing, a gear set received in the transmission device having a first gear wheel, which is rotatable about a first gear wheel axis, and a second gear wheel, which engages the first gear wheel and is rotatable abut a second gear wheel axis. In a lateral region of the first gear wheel, there is an oil guidance structure, which is designed as a component produced separately from the transmission housing, and comprises an orifice segment extending radially to the first gear wheel axis, and extends at least in part about the first transmission axis and forms a first lateral surface facing the gear wheel, leaving an intermediate space.
