汽车工业的发展,要求变速器挂挡、倒档动作更加可靠,因此,渐开线花键小锥度结合齿(套)也就运用得越来越多.插齿机加工这种小锥度齿轮时,可用摆动工作台或斜垫板这一特殊附件完成.至于小锥度与垫板角度K的关系,国内有不少人进行过探讨,“德国LORENZ公司《GEAR CUTTINGTOOLS》也给出tg∑=tgβ/tgα_p的公式.本文从齿厚的变化这一角度出发,探寻小锥度与垫板角度的关系. The development of the automotive industry requires that the gearbox be in gear and the reverse gear action is more reliable, therefore, the involute spline small taper combination tooth (sleeve) is also used more and more.Sharpening gear machining of such a small taper gear, Available swinging table or inclined plate to complete this special attachment As for the relationship between small taper and plate angle K, many people have been discussed, “Germany LORENZ company” GEAR CUTTINGTOOLS "also gives tgΣ = tgβ / tgα_p formula.This article from the perspective of tooth thickness changes, to explore the relationship between small taper and shim angle.
