Several advantages of universal test machine lead screw
Release time：2018-11-23 source：Jinan Hengsi Shanda Instrument Co., Ltd. Browse：
1. 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.
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 accuracy
Ball screws use ball movement, small starting torque, no sliding movement and other crawling phenomena, and can achieve accurate microfeeding.
4. 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.
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 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.
