Cutting-edge technology for sustainable energy production

Renewable energy is collected from resources that are naturally replenishing but flow-limited, including carbon neutral sources like sunlight, wind, rain, tides, waves and geothermal heat.In order to meet increasing worldwide demand for energy, it is necessary to harness energy from renewable sources in order to provide ecologically and economically sustainable and efficient methods of power generation.

From production machinery for solar panels to the installation and operation of wind turbines at sea, we support and enable you to produce energy from sustainable and natural resources.

ABOUT BOSCH REXROTH

Typically subsea rotors have considerably smaller rotor diameters than wind turbines of the same nominal power. This is based on the fact that, in connection with the roughly 850fold higher density of water compared to air, high forces are applied on the complete system even at low flow velocities. A straightforward and very robust way of transforming the rotor input power into power to drive a fast turning generator is based on the application of a continuous variable hydrostatic transmission as a hydraulic converter. In this case the rotor rotation is transferred to a low speed high volume displacement device which generates a hydraulic flow. This flow is driving with high efficiency a variable high speed axial piston motor coupled with a generator.

Rexroth is a specialist for various drive technologies. We believe that hydraulics are exceptionally suited for generating electricity from wave power. With hydraulics it is possible to transform linear oscillation into a controlled rotation (for driving a generator) efficiently and with a minimum on mechanics. In addition, very high transmission ratios can be achieved in an economical way, i.e. the conversion of high forces respectively torques at the input of a wave energy converter (WEC) into considerably lower torques at high rotational speeds at the generator shaft.

Our robust components meet the high demands of precision, reliability and safety, having proven themselves over many years. They can be modularly expanded depending on their requirements and can also adopt additional functions, Bosch Rexroth assembles customized solutions that are perfectly suited to your requirements..

Modern gearboxes in wind turbines put significant demands on the oil quality. Yet despite their high efficiency, they create energy losses that are released in the form of heat and have to be dissipated. Both requirements are perfectly mastered by the pump filter units from Bosch Rexroth.
