In the case of AND combinations, synchronous couplings are designed with a locking device to prevent disengagement and assure full combined power. Additionally, the couplings may be designed with a pawl-free device, which provides the disconnection of a turbine from the gear system for engine maintenance, but allows the further operation of the gear system without any limitations. The complete gear unit concepts available provide a wide choice of operational propulsion systems. This certification, along with an accountable and involved team, and testing on our own test bed, are the guarantees of a trouble-free product. Its skilled service specialists are always ready to provide the customer with efficient, as well as professional, support.
Spare parts are available throughout the lifetime of the gear unit.
MAAG gearboxes are installed in the Tirrenia fast ferries MDV 3000, built by Fincantieri. Two gear units are installed between the LM 2500 gas turbines and waterjets and two between the Diesel engines and waterjets. The technical requirements that are currently being placed on gear design transmissions are becoming more challenging, due to the ever increasing power of prime movers. High power propulsion gears are being manufactured by MAAG in Switzerland for fast ferries, cruise liners and naval applications in accordance with customer specifications.
