Gearing unit for a drive assembly and method for mounting the gearing unit

A method for mounting a gearing unit, the method, comprising:

• providing a gearing housing having a first housing component, the gearing housing defining an accommodation space;
• forming a gear wheel assembly by meshing an intermediate shaft and an output shaft, wherein the gear wheel assembly is configured to convert a drive torque of a drive assembly and includes an input shaft defining a main axis;
• inserting the gear wheel assembly into the first housing component;
• connecting a second housing component to the first housing component, wherein the second housing component and the first housing component define the accommodation space therebetween, wherein the gear wheel assembly is arranged in the accommodation space;
• inserting the input shaft into the accommodation space coaxially to the main axis via a mounting opening arranged in at least one of the first or second housing components, wherein the input shaft is brought into meshing engagement with the intermediate shaft;
• and
• inserting a closure cover into the mounting opening, wherein the closure cover closes the mounting opening, wherein a venting device is integrated in the closure cover and is arranged coaxially to the main axis and on one axial end side of the input shaft, the venting device extending through the closure cover to the accommodation space.
