空心滾珠絲杠適合于高精度的機床，空心滾珠絲杠可以很好地配合傳送機構的高速運行，尤其是在要求高精度定位時，因為運動會產生熱，熱脹冷縮，熱會使得滾珠絲杠膨脹，為了防止滾珠絲杠的這一變化，空心滾珠絲杠應運而生，空心滾珠絲杠因為是中空的，阻隔了熱傳導，從而達到冷卻的效果。而且因為絲杠軸的中空以及軸兩端的標準化加工，是減小熱膨有效的方法。

Hollow ball screw is suitable for high-precision machine tools. Hollow ball screw can cooperate well with the high-speed operation of the conveying mechanism, especially when high-precision positioning is required. Due to the heat generated during movement, thermal expansion and contraction can cause the ball screw to expand. In order to prevent this change in the ball screw, hollow ball screw has emerged. Hollow ball screw, because it is hollow, blocks heat conduction and achieves cooling effect. Moreover, due to the hollow of the screw shaft and standardized processing at both ends of the shaft, it is an effective method to reduce thermal expansion.

空心軸滾珠絲杠主要有以下幾個優點：

The hollow shaft ball screw has the following advantages:

穩定的定位精確度

Stable positioning accuracy

熱膨脹會導致滾珠絲杠的精度減低，由于空心軸抑制了由于溫度升高而造成的熱脹，所以能夠是的滾珠絲杠的精度穩定。

Thermal expansion can lead to a decrease in the accuracy of the ball screw. As the hollow shaft suppresses the thermal expansion caused by temperature rise, the accuracy of the ball screw is stable.

有效防止各部分位移

Effectively preventing displacement of various parts

還是通過降低熱膨脹的發生，將滾珠絲杠支撐軸和底座位移控制在zui小的范圍內，同時空心軸的冷卻作用有效地阻隔了對其他部位的熱傳導，從而避免了工作臺因為熱而發生變形。

By reducing the occurrence of thermal expansion, the displacement of the ball screw support shaft and base is controlled within a small range. At the same time, the cooling effect of the hollow shaft effectively blocks heat conduction to other parts, thereby avoiding deformation of the workbench due to heat.

有效縮短預熱時間

Effectively shorten preheating time

空心軸冷卻作用可以降低溫度上升的幅度，從而縮短了設備的預熱時間。

The cooling effect of the hollow shaft can reduce the amplitude of temperature rise, thereby shortening the preheating time of the equipment.

有效維持滾珠絲杠的潤滑性能

Effectively maintaining the lubrication performance of ball screws

因為避免了滾珠絲杠的發熱，減緩了潤滑油變質的速度，可以更好保持潤滑油的有效性。

Because it avoids the heating of the ball screw and slows down the rate of lubricating oil deterioration, it can better maintain the effectiveness of the lubricating oil.
