Research on pitch error measurement method of non-circular gear based on digital twin

Abstract

Aiming at the challenge of measuring errors in non-circular gears, it is proposed to establish the mathematical model of gear measuring center based on digital twin technology, and research on the detection method of pitch error of non-circular gears. The mathematical model simulates the operation of the gear measuring center, replacing traditional hardware with a 3D model and simulation software. By calculating the trajectory of the probe based on the unique characteristics of non-circular gears, the Portal program framework is developed. This framework allows for precise calculation of pitch errors and comparison with actual measurements to achieve accurate detection and analysis of the non-circular gear errors. The proposed approach reduces reliance on traditional experimental methods, offering a more efficient and accurate means of analyzing non-circular gear errors.
