Companies: Centa Power Transmission - Patented design
When looking at a yacht, the first thing normally taken into consideration is the shape in terms of design and construction material followed by what there is in terms of gear, accessories, and optional extras . However there are several small specials which make the difference between one model and another which have to do with reliability. As an example ‘elastic’, ‘flexible’ joints between a yacht’s drives and gear boxes which could compromise the smooth running of any yacht when misaligned as they can create uncomfortable vibration and undesirable noise along the entire length of the hull. For this very reason Centa Transmission drives from Germany which has acquired great reputation with more than six million installations to its name and loads of know how by working closely with major engine brands and hydraulic pump manufacturers. Centa has delivered ‘flexible’ universal joints to the yachting world some of which are patented and have enjoyed confirmed reliability through time. We went to visit the Italian branch of the company in the province of Milan and popped a few questions to Gianluca Monico General Manager. Mr Monico could you outline where does Centa come from and what does it do? Centa Antriebe Kirschey GMBH was founded in Germany in 1970. Today it represents the largest manufacturer and distributor of ‘elastic’ or ‘flexible’ universal joints and carbon drive shafts in the world. Large investments were dedicated to R & D and thanks to this team work the company patented several project designs which have proved very successful over a span of 50 years. Centa today sports a network of ten affiliates and twenty distributors which cover practically all of the global market. US group Rexford acquired Centa in February 2018 (they’re quoted on the NYSE market) and employ 8,000 staff all told. It will be flanked by an entire complementary product range which is poised to ensure further growth to both realities. Centa deals in several sectors including the luxury yachting one which represents about 40% of its turnover in Italy. What’s the reason for this extraordinary success? Centa’s targeted markets range, in essence from different industrial machinery deployed to dig, lay dumpers, apply tarmac, milling machinery, to recreational boats, motor trade, generator sets, main engines, boogie drives for trams and so on...diverse percentages registered are in function of a given specific market. Italy’s yachting market provides Centa with about 40% of its turnover and the reasons for this success are surely innovation, product reliability and quality which have all greatly contributed in making Centa world market leader.
Centa’s core business is the manufacturing and marketing of universal ‘flexible’ joints. What are they and what are they used for? Universal ‘flexible’ joints are necessary when dealing with power driven shafts to dampen torque vibration which normally derives when converting linear motion produced by an engine’s cylinders into a rotary one developed by drive shafts and being flexible they have a wider tolerance range in terms of misalignment between various power houses. Furthermore they enhance vibration reduction caused by drive shafts. Universal joints are essentially made up of two kinds, ‘flexible’ and direct rigid ones, the first one is deployed to deliver less than ‘standard’ no no’s while the second does the opposite. Centa effectively covers the entire range of solutions with more than 35 product families which are underscored by specific construction modules which include several products used in more than one market sector.the effective range of application starts from a handful of Nm in terms of torque and up to over 650,000 Nm. The range of Centa’s drive shafts in carbon complete the picture In other words we’re saying Centa’s production can suit yachts of all sizes. Which are the strong points of your product range? Centa boasts many patented products, which means that necessarily some of these are unique. The CENTAX LFSM series features integrated universal drive shaft joints, while the CENTAX NLFS series is designed for free standing applications meaning where engines and inverter transmission drives are separate. The capacity for this latter series to effectively function safely also with a much higher tolerance of
misalignment factors - twice and even three times more than the competition - is thanks to state of the art cutting edge applied technology. This translates into patented shaft coupling with integrated thrust flexible bearings inside the universal joint which dampen vibration and enhance greater on board comfort. Are your universal coupling joints all made in Germany? Centa’s entire production is manufactured in Germany. Centa also controls the production of the ‘elastic’ elements of the joint, which for some aspects is the most delicate part and for others it is the most valuable in terms of product reliability. Some of the metal parts requiring little technology can be manufactured according to Centa’s designs in the company’s premises all over the world, but the choice to build every ‘elastic’ element at HQ in Germany is going against our competitors’ current trends since they have redirected several production sites to Countries where labour costs are not comparable to European ones. Moreover Centa possesses a technical department which controls vibration to torque coefficients in Germany and can produce ad hoc machinery for everyone of its market requirements.
