前言我厂新产品单缸摩托车有一个零件——链轮,它的齿形是由三段圆弧和一个偏心构成的圆柱直齿齿形,这种齿形不能用标准链轮滚刀来加工,而必须根据这三段圆弧和一个偏心设计新的链轮滚刀。迄今,国内叙述和设计滚刀法向齿形的普遍方法都是将工件和刀具表面共轭规律当做齿轮副的平面啮合运动问题来处理的。本文将工件和刀具齿形表面当做空间共轭运动的几何问题,它的理论基础是:用通过工件螺旋面与刀具齿形表面接触线的平面截工件表面和刀具齿面,所得截线应有公切线。这种
Preface Our new product cylinder motorcycle has a part - sprocket, its tooth shape is composed of three sections of circular arc and an eccentric cylindrical straight tooth shape, this tooth shape can not be used to standard sprocket hob However, the new sprocket hob must be designed based on the three arcs and one eccentricity. Up to now, the common method to describe and design hob normal tooth profile is to treat the conjugate rule of workpiece and tool surface as the plane meshing motion of gear pair. In this paper, the workpiece and the tool tooth surface geometry as a conjugate space motion problems, and its theoretical basis is: with the workpiece through the helical surface contact with the cutter tooth surface of the cross-sectional workpiece surface and the cutter tooth surface, the resulting cross-sectional line should have Male tangential.
