FRICTION WHEEL DRIVE TRAIN FOR A WIND TURBINE

摘要

A constant speed ratio speed increaser friction wheel drive train for a wind turbine is disclosed. The drive train may include at least one drive wheel adapted to receive mechanical energy from a main shaft of a wind turbine and capable of rotating at an input rotational speed, the at least one drive wheel constructed of a plurality of drive wheel segments and at least one driven wheel in contact with and rotating against a surface of the at least one drive wheel at an output rotational speed, the output rotational speed varying with the input rotational speed.
