Abstract

The ring gear and flywheel are interference fit. In order to verify whether magnitude of interference meets the processing requirements, the size change of the 40Cr ring gear before and after heating is measured. Measurement accuracy of ring gear measurement equipment should reach 0.01mm. Due to the machining errors of the components, assembly errors, elastic deformation and so on, the tilt of axis is almost universal. Therefore, the measurement accuracy of ring gear measurement equipment is reduced. The correction method of axis tilt error based on collinear measuring heads is proposed for the problem of measurement accuracy reduction due to the tilt of axis. Firstly, the physical model of axis tilt error is studied, and the corresponding mathematical model is established according to multi-body system theory. Secondly, the mathematical model of correction of axis tilt error based on collinear measuring heads is established and the tilt correction factor is solved. Finally, the system consisting of 2 eddy current sensors and 1 standard bar is used to identify the parameters of algorithm. Simulation results show that this algorithm can be very good for correction of axis tilt error when shaft inclination angle is in the range of 5o. The ring gear measurement accuracy after correction of tilt error can meet the processing requirements of interference magnitude
