Within a drive train, the efficiency of the individual components affects the overall efficiency. Therefore, each individual component should be designed to operate at maximum efficiency from onset. In addition to offering precision and low-wear gear reduction, Trochoidal RV reduction gears from Nabtesco achieve an efficiency rating of 85%, enabling the construction of energy-efficient and high-torque machines. They come ready to be installed and are already filled with grease. Due to their high gear reduction ratio and the high rated torque, these gears may, for example, be used in applications that previously required hydraulic systems. To promote renewable energy sources, the company has developed special high-efficiency gears for wind power nacelles and their rotor blade adjustments. When compared to the conventional planetary gears, these feature up to five times the torsional rigidity, up to seven times less backlash and a 30% lower breakaway torque. The company has also developed a tracking system for solar panels that significantly improves the energy yield in comparison with rigid panels.
