　　The ball spline shaft is also called the ball screw. Why are there two names? Then we have to start from the region. Many people in the six main material areas of the ball screw have different names, so there will be There are many, many names, but the end product is all the same. The ball spline shaft is mainly composed of screw, nut and ball, and the ball screw is composed of six main materials made of screw, nut, steel ball, pre-press, reverser ball screw, and dustproof. Its function is to convert rotary motion into linear motion, which is a further extension and development of the screw. The significance of this development is to change the screw from rolling action to sliding action.

　　The ball spline shaft is the most commonly used transmission element in machine tools and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial repetitive force. It also has high precision, reversibility and Features of high efficiency. Ball spline shaft is also called ball screw and ball screw.

　　The function of the ball spline shaft is to convert rotary motion into linear motion. Because of its small frictional resistance, the ball spline shaft is widely used in various industrial equipment and precision instruments. Ball screws are widely used in various industrial equipment and precision instruments due to their small frictional resistance of the six main materials made of ball screws. It is one of the most commonly used transmission components in machine tools and precision machinery. Taiwan ball spline shaft bearings are based on the product technology accumulated over the years. From materials, heat treatment, manufacturing, inspection to shipment, all are based on Strict quality assurance system to manage, so it has high reliability.

　　The ball screw is generally used in the six main material dynamic fields of the precision transmission ball screw that rotates into a linear motion, and more and more replaces the field of the cylinder drive and the trapezoidal screw pair. Now the enterprises that produce servo motors try to make their products , that is, the servo motor strives to perfectly combine with the ball screw pair, so the positioning error of the ball screw pair has become less important. The positioning error of the ball screw pair can be compensated by the universal gear ratio of the servo motor, but for If the screw pair is not concentric, the servo motor has no choice. This is why the general rolled ball screw pair cannot replace the ground ball screw pair, and it is difficult to be competent in the field of precision transmission. The main function of the ball screw is to convert rotational motion into linear motion. Motion, or torque, is converted into six major material overlay forces made by axial reverse ball screws, which are characterized by high precision, reversibility and high efficiency.

　　Advantages of ball screws:

　　1. More power saving, the driving torque is only 1/3 of that of the sliding screw pair, which has higher motion efficiency and can save more power.

　　2. Micro-feeding is possible. The six main materials of the ball screw pair are made of ball screws, so the balls are used to move, so the starting torque is extremely small, and there will be no crawling phenomenon like sliding motion, which can ensure accurate micro-feeding .

　　3. Guarantee of high precision, the ball screw pair is produced consistently by high-level mechanical equipment, and the production precision is higher.

　　4. No backlash, high rigidity The Taiwan ball spline shaft can be preloaded, because the preload can make the axial clearance reach a negative value, and thus obtain higher rigidity (by adding preload to the ball in the ball screw, in the actual When used in mechanical devices, etc., the rigidity of the mother part can be enhanced due to the repulsive force of the roll).

　　5. Smooth action, the ball spline shaft has higher efficiency than the sliding screw, and the required torque is only less than 30%. Linear motion can be easily transformed into rotary motion. The ball spline shaft maintains smooth motion characteristics even with preload.

　　6. No backlash and high rigidity, the ball spline shaft adopts the Gothic full groove shape, and the shaft direction clearance can be adjusted to a minimum and can be easily rotated.

　　7. The excellent durability of the ball spline shaft, and the preload adjustment between one or two nuts can eliminate the gap in the axial direction, so that it has the appropriate rigidity that can meet the service conditions.

　　From the above description, it can be seen that the six main materials of the ball spline shaft are made of six materials such as screw, nut, ball, pre-press, reverser, and dustproof. His advantages include saving power, precise micro-feeding and high security. The ball spline shaft has its own exclusive advantages, which are the main factors that cannot be replaced by other screw rods.
