Variable pitch mechanism for propeller
专利汇可以提供Variable pitch mechanism for propeller专利检索，专利查询，专利分析的服务。并且PURPOSE: To enable pitch angles of blades to be changed simultaneously, by a method wherein a device is constituted such that a short shaft, which can move in the axial direction, and a large number of blade shafts are coupled through the medium of pantograph mechanisms and the blade shafts are caused to spin through the movment of said short shaft in the axial direction.
CONSTITUTION: In order to change a pitch angle of each blade 3, an control rod 5 is driven in the direction of an arrow mark, and with the movement of the control rod, the short shaft 6 also moves in the same direction. Consequently, pantograph mechanisms 7A and 7B, each of which consists of links 8, 10, 12, and 13, are driven. As a result, a rotative link 10 turns in the direction of an arrow mark about a blade shaft 4, and this causes changes in the pitch angle of each blade 3. In case the control rod 5 is driven in the reverse direction, each blade 3 turns in the reverse direction.
