The ball screw rotary motion into a linear motion , or linear motion into rotary motion of the desired product .
◎ Ball by a screw , nut and ball components. Its function is to convert rotary motion into linear motion, which is a further extension and development of ball screw , the significance of this development is to become the bearing from sliding action rolling action . With little friction, ball screws are widely used in various industrial equipment and precision instruments.
◎ ball screw drive components are most commonly used on machine tools and precision machinery , and its main function is to convert rotary motion into linear motion , or to convert torque into axial forces repeatedly , while both high-precision, reversibility and high efficiency.
◎ Ball features:
1, compared with ball screw drive torque sliding 1/ 3
As there are many balls rolling motion between the screw shaft and ball screw nut , they are able to get higher efficiency of movement . Compared with the previous slide screw vice drive torque of 1/ 3 or less, that the power needed to achieve the same results as using the rolling motion screw pair is 1/3 . Helpful in saving .
2 , to ensure high-precision
Ball screw is made ??in Japan of the world 's highest level of consistent production out of machinery and equipment , especially in the grinding , assembly, inspection of the process plant environment, temperature and humidity were strictly controlled, because the sound quality management system so that accuracy can be fully guaranteed.
3, the micro-feed may
Ball screw ball movement , so the starting torque is extremely small, creeping phenomenon does not appear that the sliding motion , to ensure accurate micro-feed .
4 , no backlash , high rigidity
Ball screw can be added to the pressure , due to the negative pressure axial clearance can achieve , and then get higher rigidity ( the ball screw ball through to add to the pressure , and other mechanical devices used in practice , because the ball repulsion can enhance the rigidity of the nut part ) .
5 , high feed may
Ball movement due to the high efficiency, low fever , so I can feed high-speed ( sport ) .
