(接上期)(3)齿形轮廓的建立。以偏转面为中心镜像齿形中心线,得到一侧齿槽中心线(图37)。图37以齿形中心面为对称面,镜像一侧齿槽中心线,得到另一侧齿槽中心线(图38)。
(Connected) (3) the establishment of tooth profile. The center of the deflection surface is mirror image of the center line of the tooth, resulting in one side of the center line of the tooth (Fig. 37). Fig. 37 shows the center line of the tooth on the side of the tooth with the center of the tooth profile as the symmetry plane, so as to obtain the center line of the tooth on the other side (Fig. 38).
