Ball screw design and selection

The complete design and selection of the ball screw pair, in addition to the transmission stroke (indirectly affects other performance parameters), lead (selected in conjunction with the design speed and motor speed), use state (affecting the force), rated load (especially dynamic Load will affect life), component rigidity (affecting positioning accuracy and repeat positioning accuracy), installation form (force system composition and mechanical model), load pulsation (determining safety with static load), shape characteristics (affecting manufacturability and In addition to factors such as installation), it is also necessary to check the repeat positioning accuracy, positioning accuracy, strut stability, limit speed, peak static load, and limit speed (Dn value) of the circulatory system of the selected specifications, and then make corrections and selections. In order to obtain fully applicable specifications, the characteristic parameters of related parts such as motors and bearings can be determined.
