三角花键是靠侧面传递扭矩的。由于齿数较多,当转过一个齿时,中心角变化不大,便于零部件的装配和调整。经常用于许多机械产品的传动系统或操纵系统中某些装置的联接。据 GB1145-74规定,外花键可以用圆盘铣刀加工成直边齿形,以简化刀具。即使如此,由于齿槽角(?)=90(?)+157(?)/Z,随齿数而变,所以仍要设计制造各种不同(?)值的专用铣刀。为了应急,我们常常对试制产品中的许多外三角花键,其齿形角一律取(?)=90(?),从而可以在铣床上用普通的铣刀加工,不再需要任何专门的设备和专门的工具。而且运行良好。 Triangular spline is by the side of the torque transmission. Due to the large number of teeth, when turning a tooth, the center angle changes little, facilitating the assembly and adjustment of components. Often used in many mechanical products, transmission system or some of the operating system coupling. According to the provisions of GB1145-74, the external spline cutter can be processed into a straight edge tooth profile, to simplify the tool. Even so, because of the cogging angle (?) = 90 (?) + 157 (?) / Z, with the number of teeth, so you still want to design and manufacture a variety of different values? In order to be able to respond to emergencies, many of the outer triangular splines in our prototypes are often subjected to a tooth profile angle of 90 (?) So that they can be machined on a milling machine using a conventional milling cutter, eliminating the need for any special equipment And specialized tools. And it works well.
