Ball Selection Step 1. Determine the positioning accuracy 2, to determine by the motor and lead screw speed of claim 3, view the nut size determination of the shaft end travel and related data 4. distribution (acceleration and deceleration by the load and speed ) to determine the average axial force and speed 5, is determined by averaging the axial preload force 6, life expectancy, the ball screw shaft axial load, speed determination dynamic load rating 7, the basic dynamic load rating, lead to buy Ball , critical speed, DmN value limits determine the outer diameter of the screw and nut in the form of 8, diameter, nut, preload, load determining rigidity (machine design) 9, the ambient temperature, the nuts and the cumulative total length determine the thermal variations lead 10, the wire bars rigidity, thermal displacement determined pre-tension 11, highest machine speed, rise time, screw specification determines that the motor driving torque characteristics and specifications of the ball screw 1, small friction loss, high transmission efficiency because the ball screw of the screw shaft There are lot of ball rolling motion between the nut and the screw, it is possible to obtain a high efficiency of movement. Compared with the past sliding ball screw drive torque reaches 1/3 or less of the ball screw, which reached the power required for the use of the results of the same movement of the sliding screw vice 1/3. Helpful in saving. 2, high precision ball screw is generally used in the world's highest level of consistent production out of machinery and equipment ball screw plant, especially in the grinding, assembly, inspection of the process plant environment, temperature and humidity were strictly control, thanks to the improvement of the quality management system so that accuracy can be fully guaranteed.
