Unconventional speed reducer could take weight & cost off a turbine

If wind turbines are to be built larger, their designers will have to think differently about building larger components. An inventor in Dallas wants to assist with a recent design for a pitch drive could take weight off a rotor and a turbine’s main bearing. The clever cam-activated mechanism turns a ring gear by “walking”
