A ball spline is a linear, rotating device that crosses a ball screw groove and a ball spline groove on a shaft. And special support bearings are directly mounted on the nut outer circle of the ball screw and ball spline respectively. By making nuts and splines rotate or stop, only one shaft can carry out three forms of motion (rotation, straight line and spiral). The ball spline shaft rotation motion stops because the rotation of the spline shaft becomes higher and resonates close to the fixed frequency of the spline shaft. Therefore, the maximum number of revolutions is controlled by limiting the degree to which no resonance is generated. When used beyond the resonance point, or near the resonance point, it is necessary to explore the diameter of the spline shaft.
Ball spline is the use of the ball installed in the spline outer cylinder, in the rolling groove of precision grinding, one side for smooth rolling, one side for transferring torque, is an epoch-making linear motion system. Moreover, unlike the traditional construction, because a single spline outer cylinder can be pre-pressed, it can play an effective role in places where the vibration impact load is too large, where the positioning accuracy is high, and where high-speed motion performance is required. At the same time, even if it is used instead of linear ball bushing, the rated load of the ball spline is more than ten times that of the linear ball bushing in the case of the same shaft diameter, so the design can be very small. Even in the case of cantilever load, torque, etc., it can be used safely and has a long life.
