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(fù)雜雙參數(shù)包絡(luò)問題時(shí)的困難,提出通過數(shù)學(xué)變換,將此包絡(luò)問題轉(zhuǎn)化為假想平面產(chǎn)形輪與工件之間的展成問題來進(jìn)行研究.推導(dǎo)了假想產(chǎn)形面的方程和各階偏導(dǎo)矢,于是可獲得產(chǎn)形面的微分幾何參數(shù).通過分析假想平面產(chǎn)形輪與工件之間的展成運(yùn)動(dòng),即可得到被展成齒面上任意指定點(diǎn)的全部一至三階微分幾何參數(shù)
