In order to meet the demand of high-performance gear applications in the fields of aviation gear transmission, realizing the measurement of dynamic transmission errors of high-speed gears, and solving the problem that the current measurement methods rely on high-precision magnetic grating or raster and magnetic grating or raster cannot be used at high speeds. The project uses acceleration to measure the dynamic transmission error of high-speed gears. Aiming at the problems of the decoupling mechanism of acceleration on high-speed gear dynamic transmission error, the acceleration data accuracy correction and fusion mechanism, the gear dynamic transmission error decomposition method and the error source backtracking mechanism, etc., the high-speed gear dynamic transmission error measurement mechanism, acceleration data adaptive correction and fusion technology, dynamic transmission error decomposition and traceability methods are developed. Key technologies such as gear acceleration and gravity acceleration decoupling, acceleration data error compensation adaptive correction and abnormal value identification, dynamic transmission error identification and traceability and the other, are acquired. The ability to accurately and reliably measure the dynamic transmission error of high-speed gears is realized. A novel idea and method for the measurement of gears dynamic transmission errors in the field such as aviation transmission is provided, promoting the development of high-speed and high-performance gear transmission technology, and breaking excessive dependence on high precision magnetic grating or raster of dynamic transmission errors measurement on high-speed gears.
