  • an adaptation of the installation position of the drive device can be considered as an alternative option for the requirements outlined above. It is basically conceivable to install one and the same drive device in different installation positions, but it must be taken into account here that, for example, the orientation of the gears in space or even the direction of rotation of the Transmission can change. This can lead to problems with the oiling of the gearwheels or other functional parts if, for example, oiling of a transmission designed for a horizontal alignment must now ensure sufficient oiling even in an inclined alignment.
