Working principle of ball spline

Working principle of ball spline The main spline shaft, circulating sleeve, spline sleeve and ball of the ball spline have the same transmission efficiency as the ball screw. The transmission is reversible with good synchronization. Transmission products have high precision and long service life. The spline shaft is made of high-quality alloy steel medium frequency quenched HRC58, and the spline outer cylinder is made of high-quality low-carbon steel carburized and hardened HRC58, with high service life and strength.
Spline rolling bearings can control the clearance in the direction of rotation to zero clearance interference, operate at high speed, rotate at high speed, have a compact structure, and are easy to assemble (even if the spline shaft is pulled, the ball will not fall off). So the transmission efficiency is high, the positioning accuracy is high, the transmission is reversible, and the service life is long. Good synchronization, competitive price, and fast delivery.
The ball can transmit a certain amount of torque between the spline sleeve and the spline shaft. When the spline sleeve bears the load and rotates the spline shaft, three of the six load ball rows automatically center and transmit torque, while the other three do not bear the load. On the contrary, the other one has three loads that automatically center. In the ball spline, by selecting the diameter of the ball, a preload force can be generated, thereby achieving high contact stiffness, impact resistance, and motion accuracy of the jacquard key.
When the ball spline sleeve uses steel balls, it can transmit torque when linearly moving on the precision ground spline shaft. The ball spline shaft can transmit torque during linear motion. Spline shaft is a compact structure that can transmit excess loads and power, with a long service life. In addition, due to the sensitive and relatively light linear motion between the spline sleeve and the spline shaft.
Therefore, the shaft sleeve or bushing can be used for rotational motion, and the guide rail (* * * 60m/min) that can be used for high-speed movement of ball keys is a new type of transmission mechanism. At present, ball flower keys have been widely used in spindle components of boring machines, drilling machines, and combination machine tools. It is used as a precise guiding mechanism for various measuring instruments and automatic plotters, and is used for presses and automatic conveyors. The guide shaft is used as an actuator for various types of transmissions and industrial robots.
