Gearing Solutions builds small speed reducers that work as speed-increasers (for small kilowatt-rated wind turbines) based on principles similar to chain couplings. With the addition of an internal roller gear, a driver, and multiple planets, we have found that load capacities can increase up to 300%.
Our gearboxes are constructed using NU LOBE gears, which optimize the roller gear profile. These gearboxes are up to 50% shorter than standard designs, can manage 30 horsepower and higher, and can replicate NEMA dimensions.
The roller-gear matrix ranges from under 1-in. diameter to over 48 in., inputs range from as little as 4-in. lb to 10,500-in. lb and higher. Our Nulobe planetary drivers matched with the original roller gears creates a planetary gear set that puts maximum power into minimum space. We also make standard gears on customized blanks.
For one wind turbine manufacturer uses our gearbox in a particularly difficult application. They must withstand shock loads, have a reliable resolution, increase speeds (preferably by a minimum of 1 to 6) and be lightweight, long-lived, and reliable. Speed increasers are not speed-reducers run backward. In the case of increasers, speed kills the components, not torque.
