Ball screw rodIt is the most commonly used transmission element in machine tools and precision machinery. The ball screw consists of a screw, a nut and a ball.Its function is to convert rotary motion into linear motion, or torque into axial reciprocating force, with high precision, reversibility and high efficiency.This is a further extension and development of the ball screw. The significance of this development is to change the bearing from rolling action to sliding action.Due to its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments.
1.Ball screw liftCompared with other products, in the design, there are many balls rolling between the screw shaft and the nut with a driving torque of 1/3 ball screw, so it can get higher motion efficiency.Compared with the past sliding screw pair, the driving torque is less than 1/3, that is, the power required to achieve the same motion result is 1/3 of the rolling screw pair.Very helpful in saving power.
2. The ball screw with no backlash and high rigidity can be preloaded. Due to the preload, the axial clearance can reach a negative value, thereby obtaining higher rigidity. In the case of mechanical devices, etc., the rigidity of the nut portion can be enhanced due to the repulsive force of the balls.
3. High-speed feed is possible. The ball screw can realize high-speed feed movement due to its high motion efficiency and low heat generation.
4. High-precision guarantees that the ball screw is produced by high-level mechanical equipment, especially in the factory environment of grinding, assembly and inspection of each process, the temperature and humidity are strictly controlled. Due to the perfect quality management The system enables the accuracy to be fully guaranteed.
5. Micro-feeding is possible. Because the ball screw uses ball motion, the starting torque is extremely small, and there will be no creeping phenomenon like sliding motion, which can ensure accurate micro-feeding.
