The characteristics of ball screws include the following five aspects:
1. Small friction loss and high transmission efficiency
Since there are many balls rolling between the screw shaft of the ball screw pair and the screw nut, higher motion efficiency can be obtained. Compared with the past sliding screw pair, the driving torque reaches less than 1/3, that is, the power required to achieve the same motion result is 1/3 of the sliding screw pair. It is very helpful in saving power.
2. High precision
Ball screws are generally produced with the world's highest level of machinery and equipment, especially in the factory environment of grinding, assembly, and inspection of various processes. Temperature and humidity are strictly controlled, and the accuracy is fully guaranteed due to a sound quality management system.
3. High axial stiffness
The ball screw pair can be pre-pressed, because the pre-pressure can achieve a negative value between the axes, resulting in higher rigidity (by applying pressure to the ball in the ball screw, when actually used in mechanical devices, etc., the repulsive force of the ball can enhance the rigidity of the filament).
4. High-speed feed and micro-feed are possible
Since the ball screw pair uses ball motion, the starting torque is minimal, and there is no crawling phenomenon like sliding motion, ensuring accurate micro-feed.
5. It cannot be self-locked and has the reversibility of transmission.
