Ball screw linear rail by screw, nut, steel ball, prepress plate, reverse, dust device.Its function is to transform rotating motion into linear motion, which is the further extension and development of ball screw linear rail. The important meaning of this development is to change the bearing from sliding motion to rolling motion.
Characteristics for ball screw linear rail:
1, small friction loss, high transmission efficiency
Because there are a lot of ball rolling motion between the screw shaft and the screw nut of the ball screw pair, the high motion efficiency can be obtained.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 power required to use the sliding screw pair.Very helpful in saving electricity.
2. High accuracy
Ball screw linear rail pair is generally produced with the highest level of mechanical equipment in the world, especially in the grinding, assembly, inspection of the process of the factory environment, the temperature, humidity for strict control, due to the perfect quality management system to ensure the accuracy.
3. High speed feed and micro feed are possible for ball screw linear rail
Because ball screw linear rail pair is using ball motion, so the starting moment is very small, will not appear sliding movement like crawling phenomenon, can ensure the realization of accurate micro feed.
4. High axial stiffness for ball screw linear rail
Ball screw linear rail pair can be added with prepressure, because the prepressure can make the axial clearance reach negative value, and then get a higher rigidity (ball screw by applying pressure to the ball, in the actual use of mechanical devices, etc., due to the repulsion force of ball can make the stiffness of the silk mother increased).
5. It cannot be self-locked and has the reversibility of transmission
