The advantage of the ball screw
2013-03-12 Reads : 1069
The ball screw drive system is a ball rolling screw drive system as rolling media. Transmission form is divided into rotary motion into linear motion; linear motion into rotary motion, two. The ball screw has the following advantages: a smooth movement ball screw drive system as the point of contact with the rolling motion, friction is small work, high sensitivity, and no fibrillation when to start, low speed creeping phenomenon, therefore, can be precisely controlled micro to. Second, the high transmission efficiency ball screw drive system of the transmission efficiency of up to 90% to 98%, for conventional sliding screw system 2 to 4 times, such as, so to less torque greater thrust, or by linear motion into rotary motion (movement reversible). Third, the movement of high-precision ball screw drive system smaller temperature rise, can preload to eliminate axial clearance and the screw pre stretched to compensate for thermal elongation, so you can get a higher positioning accuracy and repeatability of positioning accuracy . Synchronization smooth movement, responsive, non-blocking, non-slip drive children the same parts or devices at the same time with the children the same set of ball screw drive system can get good synchronization effect. , High durability ball rolling contact at all hardened (HRC58 ~ 63) processing, and precision grinding circulation system process purely rolling six high reliability compared with other transmission machinery, hydraulic transmission, ball screws bumper transmission failure rate is very low maintenance of the ball screw is relatively simple, and just general lubrication and dust. On special occasions can work without lubrication. No backlash and high rigidity ball screw drive system uses Gothic (Gothic arch) groove shape, the steel ball with trench optimum contact in order to operate easily. Adding the appropriate preload, to eliminate the axial clearance enables the ball better rigidity, reducing the ball screw nut, the elastic deformation of screw, to achieve higher accuracy.
