Abstract
A mechanism is provided for connecting the output shaft of a wind turbine with a load rod, such as the rod of a downhole pump. The mechanism includes a drive train which converts the rotating output of the shaft to a variable amplitude reciprocating output having a frequency varying with the speed of the shaft. A control assembly adjusts the drive train to maintain the amplitude of the reciprocating output proportional with the square of the wind velocity.
