Ball Screw (Ballscrew) is a steel ball between the nut and the screw between the exercise, the traditional screw of the sliding contact and then converted into rolling contact, the ball nut in the rotary motion into linear motion of the transmission machinery components. Ball screw with high precision, high life, low pollution and to do high-speed forward and reverse drive transmission and conversion and other characteristics, as with the above characteristics, precision ball screw technology industry has become a recent and precision machinery industry positioning and measurement system One of the important components. 


 Ball Screw structure: 
 Main screw ball screw, nut, ball, mounts, wipers, and the return pipe posed, according to their circulatory system is divided into different more external circulation, internal circular, circular ball screw terminal plug . 
 Known as the ball screw ball screw, ball screw, lead screw, ball screws, or screw, screw and other names; ball screw is rotary motion into linear motion, or linear motion into rotary ideal product movement. Ball screw by the screw, nut and ball composition. Its function is the rotary motion into linear motion, ball screw which is a further extension and development, the significance of this development is the roll movement of the bearing from sliding into action. With little friction, ball screws are widely used in various industrial equipment and precision instruments. 
 Machine tools and precision ball screw is the most commonly used mechanical transmission components, and its main function is to convert the rotary motion into linear motion or torque into axial force over and over again, while both high-precision, reversible and high efficiency characteristics. 
 Ball features: 
 1, compared with the sliding screw torque vice 1 / 3: As the ball screw of the screw shaft and ball screw nut are doing a lot between the rolling motion, so the campaign can get higher efficiency. With the past than the sliding screw torque deputy of 1 / 3 of the following, that is required to achieve the same exercise the power to use the results of rolling Ball Screw 1 / 3. Was helpful in saving. 
 2, the accuracy guarantee: ball screw is manufactured in Japan the world's highest level of consistent production out of machinery and equipment, especially in the grinding, assembly, inspection of the process plant environment, temperature, humidity, a rigorous control, the sound quality management system so that accuracy can be fully guaranteed. 
 3, the micro-feed may be: is the use of the ball screw ball movement, so the starting torque is extremely small, sliding motion does not appear that the creeping phenomenon, to ensure precise micro feeding. 
 4, no backlash, high rigidity: ball screw can be added to the pressure, due to the axial clearance can achieve negative pressure, and further to the higher rigidity (within the ball screw to the ball by adding to the pressure in actual for mechanical devices, due to the repulsion ball nut can enhance the rigidity of the Department.) 
 5, high feed may be: ball screws, sport, high efficiency, small heat, so I can feed high-speed (sport).
