Application of ball spline

Application of ball spline
 
Ball spline pair is a linear motion system, which can transmit torque when the spline sleeve uses the steel balls in it to move linearly on the precision ground spline shaft. The spline pair has a compact structure, which can transmit excess loads and power, and has a longer lifespan.
Spline pairs can be divided into three types: flange type spline pairs, groove type spline pairs, and end cap type spline pairs. Usually, the radial load and transmitted torque of the flange type spline pair are greater than the other two types. The accuracy of the ball spline SLF020T2NNS-650-P0 model is ordinary grade, with a shaft diameter of 20 and a length of 650. The maximum swing of the spline shaft support part by the outer diameter of the spline outer cylinder is 137um. If it is advanced, it is 92um, and the precision grade is 58um. When replacing it, the first thing to consider is how much accuracy you originally required. It is recommended to use advanced or precision grade instead of ordinary precision for better protection
In addition, the maximum accuracy of the right angle between the end face of the spline shaft and the support part of the spline shaft is:
Ordinary grade: 27um, Advanced grade: 11um, Precision grade: 8um
Ball spline uses balls installed in the outer cylinder of the spline shaft to smoothly roll and transmit torque in precision ground rolling grooves. The ball spline adopts a unique contact point design, with a larger contact angle of 40 degrees. In addition to high sensitivity, it greatly improves load capacity and is suitable for environments with large vibration impact loads, high positioning accuracy requirements, and high-speed motion performance. It can also play an effective role in such environments
At the same time, the rated load of ball splines is more than ten times that of linear bushings, making the design very compact. It can also be safely used under the same load, torque, and other effects, and has high durability
