Analyse the tooth geometry of klingelnberg cyclo - palloid spiral bevel gear . , according to the relative position and kinematic relation of the cutter heads , virtual crown gear and the processed wheel blank , established the system of coordinates of the gear cutting , dedcuced the tooth face equation of the virtual crown gear , according to relations of the gear cutting and space theory of engagement , deduced the tooth face equation of klingelnberg cyclo - palloid spiral bevel gear , and drawing the three - dimensional graphs of the virutal crown gear and klingelnberg cyclo - palloid spiral bevel gear according to the design and setting parameters 對克林貝格擺線齒錐齒輪進行齒面幾何分析。根據(jù)銑齒加工中刀盤、搖臺和輪坯的相對位置和相對運動關(guān)系建立了切齒嚙合坐標系,由矢量的旋轉(zhuǎn)推導了產(chǎn)形輪齒面方程;根據(jù)空間嚙合原理和切齒嚙合關(guān)系推導了被加工齒輪的齒面方程;由設(shè)計參數(shù)和銑齒調(diào)整參數(shù)計算得到齒面離散數(shù)據(jù),繪制了產(chǎn)形輪和擺線齒錐齒輪的三維齒形。
