7 advantages of ball screw of universal testing machine

Common on the marketUniversal testing machineThere are two types of screws: ball screw and trapezoidal screw. Ball screws are generally widely used due to their small gap and high accuracy.The following is compiled by our company7Advantages.

1.High accuracy

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

2.High-speed transmission can be achieved

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

3.High efficiency and energy saving. There are many balls between the screw shaft and the screw nut of the ball screw pair to perform 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.

4.High cost performance

Ball screws are generally a bit expensive, but considering their transmission rate, service life, accuracy and other characteristics, the cost-effectiveness is extremely high.

5.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.

6.No side gaps, 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.

7.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.
