Centa Sustainable Power Systems - .PDF file.

Centa Transmissions works with scientific, marine, manufacturing and university partners in the UK, Scandinavia and Western Europe to produce sustainable power systems for wind, wave and solar power.

The company has encountered and solved a range of problems and incorporated gears, shafts and couplings into renewable power systems.

For example, planetary gearboxes, Cyclo precision gears and special bevel gearboxes have been integrated with electromagnetic clutches, electrically insulating Centalink shafts and Sibre disc brakes.

The company has also produced Centa Freewheels to solve a specific problem relating to tide direction.

According to Michael Sykes, Centa’s gears division manager, the Freewheels stop the plant from reversing its rotation as the tides ebb, flow and change direction.

The company’s Centadisc-C, a strong, long and lightweight composite shaft that was initially developed for marine drives, has been used to connect the turbine speed-increasing gearbox and the generator.

It has also been installed between the turbine blade nacelle and the speed-increasing gearbox.

Special three-way spiral bevel gears are used for pitch actuation, ensuring that the turbines point into the wind at all times for maximum benefit.

Centa’s Sibre disc brakes are used extensively on wind-turbine applications.

Flexible couplings handle simultaneous combinations of angular and radial misalignment and axial ‘end float’, while absorbing high levels of torsional stress, resulting from driving unit vibration or momentary shock loads, to increase drive performance and reduce maintenance costs and plant downtime.

Centa’s couplings are used in industrial plants, generators, pumps, compressors, marine propulsion, rail traction, construction machinery and mechanical handling and are all manufactured under ISO9001, while meeting the requirements of international classification societies.

The company can integrate bespoke and existing products to solve complex engineering problems.

Centa Transmissions

Founded in 1979, Centa Transmissions, is a specialist in the design, specification and manufacture of mechanical power transmissions for all types of industrial, plant and marine applications. Part of international group Centa Antriebe Kirschey, Centa supplies flexible couplings, gears, gearboxes, brakes and bespoke engineered drives to any specification and for any application.

Today, Centa is at the forefront of drive technology, having solved countless drive problems for international and UK manufacturing businesses. Centa’s reputation is built on the ability to solve problems, often specifying a combination of products that, as well as couplings, include precision gears, gearboxes, electromagnetic clutches and speed reducers. Centa has also developed their highly successful carbon fibre composite shafts for ships and boats and these are capable of covering spans of 10 metres without support.

Centa is also heavily involved in the renewable energy sector, working with research associations and specialist manufacturers to create mechanical transmission drives for systems in wind, wave, tidal and solar energy. With long-time involvement in the power generation sector, Centa is ideally placed to ensure that these environmentally friendly systems benefit from reliable and trouble-free drives, often submerged or in hard to reach locations that demand robust, totally sealed, maintenance-free operation.
