7-step analysis of lead screw of universal testing machine

Universal testing machineThe details of the problem are mainly reflected in the use of various parts. The following is the main introduction content of the universal test machine lead screw introduced by our company for your reference.

1. High efficiency and energy saving

Since there are many balls between the screw shaft of the ball screw pair and the screw nut for rolling movement, the movement 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.

2. High-speed transmission can be achieved: ball screws can achieve high-speed transmission due to high movement efficiency and low heat generation.

3. High accuracy: The ball screw uses ball movement, small starting torque, and no sliding movement and other crawling phenomena can be achieved.

Accurate microfeeding.

4.Universal testing machineHigh cost performance: Ball screws are generally a little more expensive, but considering their transmission rate, service life, accuracy and other characteristics, the cost performance is extremely high.

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. No side gap and high rigidity: The ball screw can be applied to the pressure, because the pressure can make the axial gap reach a negative value, thereby obtaining higher rigidity.

7. 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 service life.
