  • Modular gondola drive for a floating device
    Patent number: 8821200
    Abstract: A gondola drive for a floating device has an underwater housing circulated around by water. The gondola drive contains a drive module which has a drive module housing and a shaft disposed therein, a transmission module with a transmission module housing and a transmission disposed therein and a propeller. The drive module and the transmission module are each configured as separate components connected to one another such that the drive module housing and the transmission module housing form at least a part of the underwater housing and that the shaft is coupled to the transmission for driving the propeller.
