Characteristics of the running screw of the electronic universal test machine

1. Self-locking:
Self-locking is generally inversely proportional to transmission efficiency. The higher the transmission efficiency, the smaller the self-locking efficiency. therefore,Electronic universal testing machineBall screws have almost no self-locking properties, while trapezoidal screws have a certain self-locking properties.
2. Economy:
Because the structure of the electronic universal test machine ball screw is more complicated than that of the trapezoidal screw, the price is still higher than that of the trapezoidal screw. However, with the increase of automation equipment and the output increases, the price difference becomes smaller and smaller.
3. Transmission speed:
The ball screw is rolling friction, and the trapezoidal screw is sliding friction. When working, the temperature rise of the former is much lower than the latter, so it can undertake the task of high-speed transmission.
4. Service life:
The surface damage of rolling friction is much smaller than that of sliding friction. Therefore, when the cleaning and lubrication conditions of the electronic universal test machine meet the conditions, the maintenance life of the ball screw is much higher than that of the trapezoidal screw.http://www.hssdtest.com/
