Abstract
PURPOSE: To insure change of blade angle by moving an operating plate with a screw and the reduction gears which employ a small reversible motor with several watts through several tens of watts, require neither hydraulic source nor air source, can be manufactured at a low cost and simple in mechanism.
CONSTITUTION: The blades 1 of a blower can be rotated on a shaft 2 by a blade- angle changing lever pin 3. An auxiliary plate 5 is attached to operating disc plate 4 and a blade-angle changing lever pin 3 is fitted in. The pin 3 is moved to change the fitting angle of the blades 1 by transferring the plate 4 right and left. When a fixed electric contact 14 or 15 is operated, a small-sized reversible motor 10 revolves clockwise or counterclockwise. Thereby, a screw 11 is turned and, the plate 4 is transferred right and left while guided by a guide pin 8 to transfer the lever pin 3 right and left so that the fitting angle of the blades 1 is changed.
