High Precision SFU 4010 Ball screw adjustable axial clearance SFU 4010 ball screw for CNC machine

1. Ball Screw Description:

Ball screws are ideal for converting rotary motion into linear motion or converting linear motion into rotary motion.

Ball screw is the most commonly used transmission component in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion or to convert torque into axial repetitive force, which is high precision, reversibility and high. The characteristics of efficiency. Ball screws are widely used in a variety of industrial equipment and precision instruments due to their low frictional resistance.

The ball screw is composed of a screw, a nut, a steel ball, a pre-compression piece, an inverter, and a dustproof device. Its function is to transform the rotary motion into a linear motion. This is the further extension and development of the Acme screw. The significance of this development is to change the bearing from a sliding motion to a rolling motion.

2. Ball Screw Principle

1. According to the national standard GB/T17587.3-1998 and application examples, the ball screw has been basically replaced.

A trapezoidal screw, commonly known as a screw, is used to convert a rotary motion into a linear motion; or to convert a linear motion into a rotary motion actuator with high transmission efficiency, accurate positioning, etc.

2. When the ball screw is used as the active body, the nut will be converted into a linear motion according to the lead angle of the screw according to the rotation angle of the corresponding screw. The passive workpiece can be connected through the nut seat and the nut to realize the corresponding linear motion.
