How to consider the use of lead screws of universal testing machine

1. Long service life

The surface damage caused by rolling friction is small, so when the conditions such as cleaning and lubrication are met, the ball screw maintains a high life.

2. High accuracy

Ball screws use ball movement,Small starting torque,There will be no crawling phenomena such as sliding movement,Achieving accurate microfeeding.

3. No side gap and high rigidity

Ball screw can be pressed,Because the pre-pressure can make the axial clearance reach a negative value,In turn, higher rigidity is obtained.

4. Universal testing machine is efficient and saves energy

Since there are many balls between the screw shaft and the screw nut of the ball screw pair are performing rolling movement,Therefore, the exercise efficiency is high. That is, if the same large load is driven, a ball screw can use a smaller driving power, which can reduce costs and save energy.

5, no self-locking

Self-locking is generally inversely proportional to transmission efficiency. The higher the transmission efficiency, the smaller the self-locking ability. Therefore, the ball screw has almost no self-locking ability.

6. High-speed transmission can be achieved

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