SIMPLIFIED LOCKING METHOD FOR VALVE ROD & TWIN TUBE ASSEMBLY OF CONTROLLABLE PITCH PROPELLER SYSTEM

摘要

PURPOSE: A method for simplifying tightening of a valve rod and a double hydraulic pipe of a variable-pitch propeller is provided to remarkably reduce working time by simplifying a tightening work of a valve rod and a double hydraulic pipe. CONSTITUTION: A method for simplifying tightening of a valve rod and a double hydraulic pipe of a variable-pitch propeller is as follows. An O-ring or a gasket(5) is inserted between the flanges of a first valve rod(1) and a second valve rod(2) and is in contact with the flanges. One end of multiple connecting bars(3) are hung on the flange of the first valve rod, and the other ends are toward the second valve rod. A connecting wire(4) binds the other ends of the connecting bars.
