Abstract:
The invention relates to a gear unit, in particular for foundation engineering devices, comprising a gear housing and a pressure device for changing an internal pressure present in the gear housing. For a precise pressure balance to the environmental pressure it is intended that an active setting device is arranged which can be controlled by a control device in order to change the internal pressure. The invention further relates to a method for pressure balance related thereto.
