Description
A vital component on the CP propeller shaft line is the gear box. The gear box is nowadays developed as a high- technology product being integral part of the shaft line system allowing: a) optimal rotational speeds for the propeller and the engine; b) configurational arrangements (e.g. twin- in, single- out layouts); c) two- propeller speed operation; d) integration of propeller hydraulic systems and d) integration of machinery room power systems (power take- in/ power take- out).
The added functionalities require advanced product development tools and robust manufacturing technologies. On product development, the design party needs to possess significant product knowledge through applications in lengthy periods of time. The design party must also have significant knowledge of all relevant machinery room equipment – from the propeller to the power supply unit - allowing the best integrated solution. The manufacturing party needs to have adequate tools and experienced personnel on gear technologies. In our recent working arrangement, Wartsila selected Flender GmbH, which is now responsible for the production and delivery of the product.
The paper presents the technical advances for a number of marine market applications showing the added value of the gearbox technologies to the customer.
