Abstract
A method based on the theory of gearing and the gear generation mechanism is proposed to analyze the influence of geometric errors of a linear axis on the position and orientation of instantaneous contact line. The mapping relation, utilized to describe the gear profile and the grinding disk profile is established between intrinsic parameters of a grinding machine and meshing parameters. Firstly, instantaneous contact line equation and error transformation matrix are built. Then six component geometric errors of a linear axis are introduced. Finally, a comparison is conducted between the theoretical contact line and the actual contact line to identify the influence of each geometric error. The application of the simulation illustrates that: the instantaneous contact line calculating method can accurately obtain the influence values of each geometric error, which provides a scientific basis for gear profile accuracy improvement in a large-scale gear forming grinding method.
