Abstract
Disclosed is high torque traction drive. The high torque traction drive utilizes planet gears that engage the inner mesh of a ring gear. The planet gears are mounted in rollers that have inner traction surfaces that engage sloped ring traction surfaces on traction rings that are attached to the ring gear. The sloped traction interface causes the rollers to move inwardly when forced toward the traction rings. The inward force on the rollers creates a shaft traction interface between a shaft and outer traction surfaces on the roller, so that rotational mechanical energy is effectively transferred between the rollers, the shaft and the ring gear. High rotational speeds can be achieved with a high degree of torque. Speed reduction ratios of at least 10:1 or greater can be achieved. The high speed drive may include exhaust turbines, steam turbines, including a Tesla turbine or Schumacher turbine, compressors, combinations of turbines and compressors, high speed pumps, dentist drills, or other devices that operate with high rotational speed.
