空心滚珠丝杠适合于高精度的机床，空心滚珠丝杠可以很好地配合传送机构的高速运行，尤其是在要求高精度定位时，因为运动会产生热，热胀冷缩，热会使得滚珠丝杠膨胀，为了防止滚珠丝杠的这一变化，空心滚珠丝杠应运而生，空心滚珠丝杠因为是中空的，阻隔了热传导，从而达到冷却的效果。而且因为丝杠轴的中空以及轴两端的标准化加工，是减小热膨有效的方法。

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.

空心轴滚珠丝杠主要有以下几个优点：

创盈彩网址The hollow shaft ball screw has the following advantages:

稳定的定位精确度

创盈彩网址Stable positioning accuracy

热膨胀会导致滚珠丝杠的精度减低，由于空心轴抑制了由于温度升高而造成的热胀，所以能够是的滚珠丝杠的精度稳定。

创盈彩网址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

创盈彩网址Effectively preventing displacement of various parts

还是通过降低热膨胀的发生，将滚珠丝杠支撑轴和底座位移控制在zui小的范围内，同时空心轴的冷却作用有效地阻隔了对其他部位的热传导，从而避免了工作台因为热而发生变形。

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.

有效缩短预热时间

创盈彩网址Effectively shorten preheating time

空心轴冷却作用可以降低温度上升的幅度，从而缩短了设备的预热时间。

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

创盈彩网址有效维持滚珠丝杠的润滑性能

创盈彩网址Effectively maintaining the lubrication performance of ball screws

因为避免了滚珠丝杠的发热，减缓了润滑油变质的速度，可以更好保持润滑油的有效性。

创盈彩网址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.
