Abstract

Abstract

The relationship between the machine setting parameter errors and the surface errors of spiral bevel gears manufactured by duplex helical method are studied. Based on the gear meshing theory,the equations of deviation surfaces are established and the analytic expression of tooth surface error caused by machine setting parameters errors are derived by MATLAB. The deviation topographies corresponding to the machine setting parameter errors are built,the mapping relationship between the each process parameter error and the tooth surface errors is analyzed,the major impact machine setting parameters are obtained. The influence weight of the change in machine setting parameters on the tooth surface error is obtained by using second order surface. Based on the tooth flank error and error sensitivity matrixes,the model for adjusting tooth flank error is developed,the generalized inverse matrix with least square method is adopted to solve the transcendental equations,and the correction quantities is obtained. A spiral bevel gear generated by the duplex helical method is used as an example to validate the effectiveness of the error correction method,the results reveal that the tooth flank errors of both side are greatly reduced.
