Ball Spline Introduction:
A spline is a linear motion system that transmits torque when a spline sleeve utilizes the steel balls in it to move in a straight line on a precision ground spline shaft. A spline shaft transmits torque when it moves in a straight line on a spline shaft. Spline shafts are those with a more compact structure, capable of transmitting excess loads and power, and having a longer life. Ball screw shaft is a mechanical element composed of screw, nut, ball and other parts, its role is to transform rotary motion into linear motion or linear motion into rotary motion, it is a further extension of the development of the traditional sliding screw.
The profound significance of this development is the same as the changes brought by rolling bearings to plain bearings. Ball screw sub due to excellent friction characteristics make it widely used in various industrial equipment, precision instruments, precision CNC machine tools. Especially in recent years, ball screws as CNC machine tools linear drive execution unit, widely used in the machine tool industry, greatly promoting the development of CNC machine tool industry.
