Rexroth has developed a new gearbox platform for turbine manufacturers with a power range of 3MW to 4.5MW.
With a compact gearbox consisting of two planetary gear stages and a helical gear stage, the company's consistent aim in developing the gearbox concept was to reduce the CoE and increase reliability. The modular concept allows rapid adaptation to customer-specific requirements, thus shortening the time-to-market. Rexroth has also standardised the parts. The planet wheel takes on the function of the outer ring of the planetary bearing and thus avoids bearing damage by a conventional rotating outer ring. The optimised tooth meshing sequence ensures the gearbox is quiet when running and allows improved noise characteristics. Optimised tooth flank roughness depths reduce the risk of micropitting.
