Key points for Ball Screws selection
To choose a perfect fit ball screw, users need to understand operating requirement, which is the fundamental principal of deciding the design. Besides,the main factors of selection include load weight,stroke, torque, positioning accuracy in a single time and repeatedly, rigidity, lead and nut's inner diameter.Among all the factors, any single factor's change will cause the change of other factors. Therefore, the balance between all factors is a must to pay attention
Service Life of Ball Screws
Even the ball screw is used under correct conditions, it would still fail after a period time of usage.
From the beginning to the unusable condition of ball screw, this period of time is called service life of ball screw, which is generally classified into the fatigue life when delamination phenomenon occurs and the accuracy deterioration life caused by wear-out, etc.
Direction of turns of ball screw thread
There are two directions of turn, right and left hand screws. Mostly, right turn screws are used.
Right hand screw
If you trace the groove in clockwise looking at the screw shaft in its axial direction, the ball thread is away from you.
(In the illustration, the spiral goes away from an end of the shaft.) Such screws are called right hand screws. As the illustration shows, the groove slants to the right.
Why do the ball screws require ball recirculation parts?
In case of a ball bearing, its steel balls roll only in a circular groove, thus there is no way for steel balls to go out of it. However, since the groove in the ball screw is helical, its steel balls roll along the helical groove, and, then, they may go out of the ball nut unless they are arrested at a certain spot.
By providing steel balls in between the screw shaft and the nut (grooves), and the balls roll on the grooves (i.e.,Change to rolling contact from sliding contact to reduce friction. Refer to the illustration below.).
