Excellent lubrication of ball screw is very necessary. If there is no sufficient lubrication, the conflict between ball and roll surface will be added during operation, and may be the main reason for shortening service life.

滚珠丝杆的润滑可选润滑脂或润滑油方法，而润滑方法大致分为手动润滑与主动强制润滑两种，可按照系统的作业速度，运用环境等需求做合适的选择。

Ball screw can be lubricated by grease or lubricating oil. The lubrication method can be roughly divided into manual lubrication and active forced lubrication. According to the operating speed of the system, suitable selection can be made according to the requirements of the environment.

润滑脂的给脂频率依据运用条件与环境而有所不同，一般现象建议每作业100KM的间隔弥补润滑脂一次，油润滑方法建议选用粘度为30~150cst的润滑油。

The frequency of grease feeding varies according to the operating conditions and environment. It is suggested that the grease should be compensated once every 100 KM interval, and the grease with a viscosity of 30-150 CST should be selected for oil lubrication.

Maintenance Method of Ball Screw Screw

丝杆所运用的润滑剂，润滑脂是运用锂皂基尼系之润滑油，其粘度30~40cst(40℃）滑油运用ISO等级32~100。

The lubricant used in the screw rod is a lithium soap-based lubricant with a viscosity of 30-40 CST (40 C) and ISO grade of 32-100.

选择依据：

Selection basis:

1.低温用处时：运用基油黏度低的润滑剂。

1. Low temperature use: use lubricant with low viscosity of base oil.

2.高温，高负荷或摇摆，低速用处时：运用基油黏度高的润滑剂。

2. High temperature, high load or rocking, low speed use: use base oil lubricant with high viscosity.

设备在长期作业后许多零件温度都会上升，这是会影响设备的作业效率。而高精准的设备影响更大，是会损坏精准度。滚珠丝杆是许多设备上都会运用的零件，作业时间久了，温度就会上升，这样就会让精准度下降，这就需要做降温处理。那都有哪些降温处理方法？

After long-term operation, the temperature of many parts will rise, which will affect the operation efficiency of the equipment. High-precision equipment has a greater impact, which will damage the accuracy. Ball screw is a part that can be used in many equipments. If the working time is long, the temperature will rise, which will reduce the accuracy, which requires cooling treatment. What are the cooling methods?

1、在满足产品需求的前提下，尽或许减小滚珠丝杆和轴承座的预紧量；

1. On the premise of meeting the product requirements, reduce the preload of ball screw and bearing seat as much as possible.

2、尽或许选取大的导程，以下降滚珠丝杆的转速；

2. Choose a large lead whenever possible to reduce the speed of the ball screw.

3、选择适合的润滑剂很重要；

3. It is important to choose suitable lubricants.

4、如有条件，运用润滑油或凉气对丝杆轴进行强制冷却。

4. Forced cooling of the screw shaft with lubricating oil or cooling gas if necessary.
