  3. Abstract : in order to solve the double parameters enveloped in the geartooth flank generating, the complicated double parameter envelope is simplified to the generating process between work - piece and imaginary crown generating gear by means of mathematical transformation. the equation of the imaginary crown generating surface and the partial derivatives are deduced, so the differential geometric parameters of the generating surface can be obtained. by analyzing the generating motion between the imaginary crown generating gear and the work - piece, all the first to third order geometric parameters of the generated tooth flank at any given point can be calculated

    文摘:為了解決直接求解展成法加工中存在的復雜雙參數包絡問題時的困難，提出通過數學變換，將此包絡問題轉化為假想平面產形輪與工件之間的展成問題來進行研究.推導了假想產形面的方程和各階偏導矢，於是可獲得產形面的微分幾何參數.通過分析假想平面產形輪與工件之間的展成運動，即可得到被展成齒面上任意指定點的全部一至三階微分幾何參數
