The function of ball screw in sticker tester

1. High efficiency, saving energy

Since there are many rolling balls between the screw shaft of the Ball Screw pair and the screw nut , the movement efficiency is high. That is, if you drive the same large load, the universal testing machine uses a ball screw to use less drive power, which can reduce costs and save energy.

2. can achieve high-speed transmission

The ball screw can realize high-speed transmission due to high movement efficiency and low heat generation.

3. High accuracy

The ball screw ball movement, a small starting torque, will not be sliding sports such as crawling phenomenon, to accurate micro feed.

4. Long service life

Rolling friction has low surface damage. Therefore, when the conditions of cleaning and lubrication are met, the ball screw of the universal testing machine has a high maintenance life.

5. No self-locking

The self-locking property is generally inversely proportional to the transmission efficiency. The higher the transmission efficiency is, the smaller the self-locking property is. Therefore, the ball screw is hardly self-locking.

6. No backlash, high rigidity

Ball screw can be added to the pressure , because the preload can make the axial gap to a negative value , and then get a higher rigidity.

7. Universal testing machine cost-effective

The ball screw is generally a little expensive, but considering the characteristics such as transmission speed, service life, and accuracy, the price/performance ratio is extremely high.
