Optimization of Grinding Wheel Profile for Gear Form Grinding

Ding Guolong;Zhang Song;Zhao Daxing;Zhao Di;Zhao Dongxiong;Hubei University of Technology;  
It is crucial that optimization of grinding wheel profile for the accuracy and efficiency of gear form grinding. A integrated mathematical model of tooth profile was established,which adopted circular curve as transition part of non-involute form of gear end-face,meanwhile,grinding wheel profile of a cogging was solved by non-instantaneous sectional envelope machining principle and analytic expression of constant intersectional point on chord tooth was derived. Adjusting grinding wheel setting angle to alter shape and position of contact line between grinding wheel and gear to make it more symmetrical; changing the position of fixed intersectional point on tooth surface to make sure it was close to pitch circle,thus the contact line was more centralized and low divergence. On the basis of using linear weighted sum method to establish muti-goal optimization module,taking highly grinding efficiency,symmetrical contact line,shortest contact line length of single tooth surface as optimization goal,the grinding wheel profile was optimized depend on programme developed on MATLAB. Finally,the effectiveness of adjusting grinding wheel setting angle and fixed point position was manifested through example's analyses.
