 High efficiency ball screw and ball screw due to reversible (ball screw) screw shaft and nut are rolling movement of the point contact, so its efficiency can be as high as 90%. Therefore only the transmission torque is only 1/3 of conventional lead screw, the ball screw mechanical efficiency than traditional lead screw. Ball (ball screw) in the tooth-type surface mining in ultra-precision machining screw serves to reduce the contact friction between the ball groove and beads, and beads between the slot for another ball rolling movement of the point-contact, low friction and high operating efficiency advantages. It is possible to reduce the motor driving force demand, thereby reducing costs. High precision testing equipment and follow standard test procedure to ensure the efficiency of the ball screw. Ball screw drives and other devices, like rolling friction, avoid hard dust or dirt into chips, so must be equipped with protective devices. If the ball screw design exposed screw on the machine should be used enclosed protective cover, such as the use of spiral tube, telescoping tube and folding casing. When installing one end of the shield is connected to the side surface of the ball nut, the ball screw is fixed to the other end of the bearing seat. If the ball screw screw expert in secluded location, you can use protective seals, seals installed at both ends of the nut. Contact resilient seal with oil made from rubber or nylon, which made the hole and screw thread to match the shape of the raceway; good contact seals dust effect, but because of the contact pressure, the friction torque slightly increase. Also known as non-contact labyrinth seal ring screw, which uses hard plastic, the opposite shape of the hole with the screw thread raceway, and a slight gap, so to avoid friction torque, but the effect of dust poor. Work should be avoided crashing guards, guards a damaged should be replaced.
