[Abstract]:The large gear measuring center is a high precision measuring equipment designed for off-line measurement of large gears. Its characteristic is that the measuring efficiency, high precision and high application range are wide. The error items such as tooth profile deviation, tooth pitch deviation, helical deviation and so on can be measured after one installation. However, due to the deformation of the measuring center structure of large gears, the top center deviates from the theoretical position and combines the characteristics of large gears with large size and large mass. When the gear is installed, it is difficult to align the geometric centerline with the rotating centerline of the main axis of the measuring instrument, and the installation error is difficult to eliminate, thus affecting the measuring accuracy for the problem of the installation error of the large involute cylindrical straight gear, and taking the large involute cylindrical spur gear as the object. The research on error compensation technology of large gear installation is carried out. The present situation of gear measurement and gear installation error compensation technology is analyzed and studied, and the mathematical modeling of involute cylindrical spur gear is carried out, and the rectangular coordinate equation and normal vector equation of involute tooth surface are derived. Combined with the two loading modes of the gear with or without the center of the measuring center, the positioning error of the gear in the two ways is analyzed, and the parameters of the installation error are determined, based on the principle of coordinate transformation. The error compensation model of gear mounting position and pose is established, and the measuring scheme of gear position and pose parameter under two kinds of loading mode is established in order to determine the gear position and pose parameter. The least square principle and practical harmonic analysis technique are adopted. The MATLAB data processing program was compiled to calibrate the gear mounting position and pose parameters, and the tooth profile deviation was calculated by combining the gear mounting posture parameters and error compensation model. Based on the same and T50 gear measuring center, the feasibility of the calibration scheme is verified by the detection of the gear template and the inner cylindrical gear, respectively. The accuracy of the error compensation system is verified by correcting the tooth profile deviation of the gear template installed with the center eccentricity through the error compensation model of the gear installation.
