Wind turbine driving air compressor - uses cam driven by blades to set up oscillatory motion in operating arm of air pump

摘要

The turbine is suited to driving air compressors to store the energy extracted from the wind. The turbine is mounted on a frame with its horizontal shaft carrying multiple blades which form the turbine wheel. A circular guide which supports the blades is fitted over the shaft and a wheel coupled to an output shaft runs on the guides. The guide is shaped as a cam with peaks and troughs spaced at equal angles around its periphery. The wheel runs on the cam surface and rises and falls with the changing radius of the cam. The oscillatory motion of the output shaft can be used to operate an air pump to permit storage of the energy gathered. The turbine has a high longevity since there is no rolling friction between the cam and its support.
