此专利是有关鼓形渐开线花键的改进,适用于鼓形渐开线外花键传动轴。由外花键将扭矩传给直齿渐开线内花键,或从直齿内花键给鼓形外花键,内外花键合起来作为一种通用连接方式而应用。外花键轴的中心线与相应的内花键中心线是不平行的。必须注意,此发明可用于传动轴的一端是鼓形外花键,另一端可为鼓形外花键或其他的通用连接方式。此发明在传动轴的一端是纯旋转运动,另一端既有轨道运动又有自转运动。这种传动通常见于摆线或马达。
This patent is an improvement on the drum involute spline, suitable for drum involute splines. Torque is transmitted from the external spline to the spur involute spline, or from the spur internal spline to the drum-shaped external spline, the internal and external splines together as a universal connection. The centerline of the external spline shaft is not parallel to the centerline of the corresponding internal spline. It must be noted that this invention can be used with a drive shaft having a male external spline at one end and a male external spline or other universal connection at the other end. In the invention, one end of the transmission shaft is purely rotary motion, while the other end has both orbital motion and rotation movement. This type of drive is usually found on a cycloid or motor.
