Abstract: Gear driving occupies an indispensable position in the field of mechanical transmission of the modern industry, better texture and mechanics characteristics of gear surface contribute to better meshing quality. Gear honing has been wildly used as gear finishing process because of its better gear surface texture and higher surface residual stress than gear grinding in recent years, especially for the development of power honing with internal gearing. In this paper, the gear surface model of the bull-gear in gear box was built based on the involute helicoid theory, and then the points of gear surface were converted to the honing wheel by using the space coordinate transform theory and matrix resolution method, the tooth surface model of the honing wheel was calculated based on the honing parameters and the conjugate contact principle of internal meshing. Through analysing the relative motion velocity vector of contact lines, the formation mechanism of gear surface texture was reflected clearly with different axis-crossing angles. The results of this research have important theoretical and instructional significance for the honing process. [Received 22 July 2016; Accepted 16 November 2016]
