Embodiment Construction

[0035] The technical solutions of the present invention will be further specifically described below through examples and in conjunction with the accompanying drawings.

[0036] Referring to Fig. 1, Fig. 5, Fig. 6, Fig. 7, a method for measuring the moment of the static center of gravity of the blade of the present invention comprises the following steps:

[0037] A. The blade 3 is weighed to obtain the weight P of the blade 3;

[0038] B. Determine the distance Y1 from the center of gravity of the blade 3 to the flange 31 of the blade;

[0039] 1) Place the balance shaft 1 on the hinge base 2, adjust its center of gravity to be at the center of the hinge base 2, balance both ends of the balance shaft 1, and measure the distance Y2 from the fulcrum center of the hinge base 2 to the end face of the balance shaft 1. At this time, the center of the fulcrum of the hinge seat 2 is just supported at the center of gravity of the balance shaft 1 .

[0040] 2) Install the propeller f...

Abstract

A method for measuring torque of static balance gravity on blade sets balance shaft on hinge base and connects balance shaft to blade to separately measure out distance from blade gravity to center line of propeller and distance from blade gravity to center line of flange.

Description

technical field [0001] The invention relates to a method for measuring the static center of gravity of a blade, in particular to a method for measuring the moment of the static center of gravity of a blade. Background technique [0002] Referring to Fig. 1 and Fig. 2, in the process of designing and manufacturing the blades of the controllable pitch propeller, P, Y and Z are measured for each blade, where P is the weight of the blade 3, and Y is the weight of the blade 3 to the center of gravity. The distance from the centerline d of the propeller, Z is the distance from the center of gravity of the blade 3 to the centerline c of the flange, and a is the distance from the centerline d of the propeller to the end face of the flange 31 of the blade. For all the blades mounted on the same controllable pitch propeller, the error shall be within an allowable design tolerance. When measuring the static balance of a single blade, it is actually necessary to measure the size of P, ...
