Abstract

PURPOSE: To obtain any desired rotational speed of a wind mill and the resultant torque in a wide range of wind speed, by means of such a structure that a conical resistant enclosing a cylindrical cam and a spring is engaged with a blade shaft and a gear, so as to control the pitch angle.
CONSTITUTION: Resistant 4A is formed with a cylindrical cam 12A provided with a cam groove 12A and projecting from the inside of its top section. The tip of rotary shaft 21 is inserted in its central hole, while a pin 13 is fitted in the cam groove 12aA. The rotary shaft 21 is provided with a flange 22 to lock the resistant 4A, while a compression spring 23 is fitted between the flange 22 and cylindrical cam 12A. When the resistant 4A is forced backward due to a wind pressure by compressing the spring 23, the rotary shaft 21 is driven by the slant cam groove 12aA via the pin 13 to turn an angle corresponding to the present wind pressure, thus setting a required pitch angle of the blade 2.
