ballscrew


There are many benefits in using ballscrews, such as high efficiency and reversibility, backlash elimination, high  stiffness, high lead accuracy, and many other advantages. Compared with the contact thread lead screws as shown in  (above),  a  ballscrew  adds  balls  between  the  nut  and  spindle.  The  sliding  friction  of  the  conventional  screw  is  thus  replaced  by  the  rolling  motion  of  the  balls.


  High efficiency and reversibility

 ballscrewef


Ballscrews  can  reach  an  efficiency  as  high  as  90%  because  of  the  rolling  contact  between  the  screw  and  the  nut.  Therefore, the torque requirement is approximately one third of that of conventional screws. It can be seen from Fig.(above) that the mechanical efficiency of ball screws are much higher than conventional lead screws. Ballscrews  have  super  surface  finish  in  the  ball  tracks  which  reduce  the  contact  friction  between  the  balls  and  the  ball  tracks.  Through  even  contact  and  the  rolling  motion  of  the  balls  in  the  ball  tracks,  a  low  friction  force  is  achieved  and  the  efficiency  of  the  ballscrew  is  increased.  High  efficiency  renders  low  drive  torque  during  ballscrew  motion. Hence, less drive motor power is needed in operation resulting in lower operation cost.
