摘要：基于螺旋锥齿轮铣齿加工展成原理,建立了齿面方程,将齿面划分为5行×9列网格,通过对网格点的计算和拟合,根据齿根过渡圆弧不干涉原则进行了螺旋锥齿轮副的三维实体造型。根据螺旋锥齿轮副的节锥角确定了齿模的加工方法,节锥角大于70°从动轮直接在加工中心上铣出齿模,节锥角小于70°从动轮以及主动轮齿模的加工先在加工中心上铣出电极,再利用电极在电火花机床上加工出齿模。
The gear tooth surface model is built by analyzing the relationship of cutter tool and workpiece,and the coordinates of points on surface are obtained by using tooth contact analysis( TCA) theory,and the gear tooth root arc is deduced by following the nonintervention principle. The three- dimensional( 3D)model of spiral bevel and hypoid gears is built in UG after the above steps were finished. The manufacturing method of tooth die which is obtained by the gear 3D model depends on whether the pitch angle is larger than 70 degree. If lager,machining center will be chosen,otherwise the method is electrical discharge machining( EDM).
