Description

Technical Field

[0001] The utility model relates to the technical field of protective mechanisms, in particular to a protective cover for a three-legged static moment measuring device. Background Art

[0002] The device used for measuring the static moment of blades in the development and production of aircraft engine and gas turbine rotor blades currently adopts an integral structure of fixed arm, movable arm and tenon. Since there are many models of engines involved, the structure and size of each model are different, and each model rotor corresponds to multiple stages of blades, each stage of the wheel has a different radius, and each stage of blades needs to design a corresponding device to measure the static moment of blades, which results in a large number of measuring devices, high cost and poor economy.

[0003] Chinese patent CN116413020A, including a fixed arm, a digital ruler, a movable arm, a tenon and a top screw, changes the overall structure of the original measuring device into an adjustable structure. The radius of the wheel disc is adjusted by moving the movable arm, so that one set of devices can complete the measurement of the static moment of different rotor blades. When measuring the static moment of each blade, only the tenon corresponding to the blade needs to be replaced to complete the blade installation. One set of devices can meet the static moment measurement of blades with different wheel disc radius sizes of multiple models, but the device can only measure the static moment of the blade in one dimension, that is, the static moment from the tenon of the blade to the far end of the blade, and cannot measure the static moment of the other two dimensions of the blade.
