2011 WIND INDUSTRY in gERMany - Wind-Energy-Market

Innovative gear technologyRexroth develops and produces all types ofgearboxes for wind turbines. They includeefficient main gearboxes, high-precisionyaw drives for permanent wind trackingpurposes, and compact pitch drives forrotor blade adjustment.REDULUS GVP-D represents an innovative,patented gearbox concept for multi-megawattturbines. For higher turbine capacitiesweight advantages of up to 15 % can beachieved compared to the gearbox conceptscurrently in use.For its main gearboxes Rexroth also offersoil conditioning. This comprises a speciallydeveloped filter cooling system that includesa particle monitor and water content sensor.Hydraulic and electrical control technologyAs a supplier of all types of drive andcontrol technologies Rexroth offers bothelectromechanical and hydraulic systemsfor rotor blade adjustment. The global marketleader in industrial hydraulics not onlysupplies hydraulic pitch adjustment systems,but also a range of other hydraulicproducts and solutions. Hydraulic drivetrain brakes and yaw drive brakes are justsome of the examples.Condition MonitoringCondition Monitoring Systems are essentialfor the reliable operation of wind turbines.Rexroth’s BLADEcontrol monitoring systemwas developed for the purpose of continuousremote monitoring of rotor blades.Based on vibration analysis the systemdetects and tracks even minor damage torotor blades.Strong deviation from the normal state isimmediately signaled to the control centerof the wind turbine, and a text message ore-mail is sent to the wind farm operator. Inextreme cases the turbine can thus be shutoff immediately, a process which can alsobe automated.ServiceThe company’s position as a leading partnerof machine and plant manufacturersaround the globe is strengthened by acomprehensive range of services.The services offered by the Renewable Energiesbusiness unit range from in-the-fieldsupport by experienced service engineersto preventative maintenance and repairscarried out to original drawings and usingoriginal spare parts in manufacturer’squality.Further informationBosch Rexroth AG is one of the world’s leading specialistsin the field of drive and control technologies.Under the brand name of Rexroth the companysupplies more than 500,000 customers with tailormadesolutions for driving, controlling and moving.Bosch Rexroth is a partner for industrial applicationsand factory automation, mobile applications andusing renewable energies.
