Four characteristics of ball screw

Original title: Four characteristics of ball screw

1. Low friction loss and high transmission efficiency

Because there are many balls in the rolling motion between the screw shaft and the screw nut of the ball screw pair, higher motion efficiency can be obtained. Compared with the past sliding screw pair, the driving torque is less than 1/3, that is, the power required to achieve the same motion result is 1/3 of the use of the sliding screw pair. Very helpful in terms of power saving.

2, high precision

The ball screw pair is generally produced continuously with the world's highest level of machinery and equipment, especially in the factory environment of grinding, assembly, and inspection. The temperature and humidity are strictly controlled. Due to the perfect quality The management system ensures the accuracy.

3. High-speed feed and micro feed are possible

Because the ball screw pair uses ball motion, the starting torque is very small, and there will be no crawling phenomenon like sliding motion, which can ensure the realization of accurate micro feed. (Guide: What are the advantages of using a cold heading machine to make fasteners?)

4, high axial rigidity

The ball screw pair can be pre-compressed, because the pre-compression can make the axial gap reach a negative value, and then obtain higher rigidity (the ball screw is actually used in mechanical devices by adding pressure to the balls. At this time, due to the repulsive force of the balls, the rigidity of the nut can be increased).

5. It cannot be self-locked and has the reversibility of transmission
