The ball screw can be lubricated to improve wear resistance and transmission efficiency. Lubricants are divided into two categories: lubricating oil and grease, lubricating oil, 90 ~ 180 turbine oil or 140 spindle oil.

滚珠丝杠是应用于自动化机械设备行业的精密仪器、大型机床的核心部件，从它产生到现在被广泛使用了一个世纪，对于他的改进却仍未停止，随着自然复杂系数的不断增加，相应的维修难度系数也有所提高。

Ball screw is the core component of precision instruments and large machine tools used in the automation machinery and equipment industry. It has been widely used for a century since it came into being. However, its improvement has not stopped. With the increasing of natural complexity coefficient, the corresponding maintenance difficulty coefficient has also increased.

在日常生活中保持丝杆占据主导的方法是使用匹配的润滑脂或润滑油进行注入，从而提高整体的运行速度，这与在链条上注入润滑油是一样的。

The way to keep the screw dominant in daily life is to use matching grease or oil for injection, so as to improve the overall running speed, which is the same as injecting lubricating oil into the chain.

随着工业自动化的发展趋势，越来越多的企业使用精密传动设备，这也是维修中的一大问题。尤其是在润滑油、润滑脂上面，润滑油通常是由滚珠丝杆壳体上的一个洞以此来作为通气孔，将润滑油注入机体。由于丝杆的主要的运作是依靠摩擦产生的，所以要注意组建的摩擦与损耗方式。

With the development trend of industrial automation, more and more enterprises use precision transmission equipment, which is also a major problem in maintenance. Especially on the lubricating oil and grease, the lubricating oil is usually injected into the body by a hole in the ball screw housing as a vent hole. Since the main operation of the screw rod depends on friction, the friction and loss mode of the screw rod should be paid attention to.

通常用毛毡圈对其进行密封，以确保不会有赃物混入，这将妨碍丝杆的正常工作，提高丝杆的磨损。如果长时间暴露在外，应使用套管进行一定的防护设施，以减少雨水的侵蚀和外部非人为因素的损坏发生。

It is usually sealed with felt ring to ensure that there is no dirt mixed in, which will hinder the normal operation of the screw rod and improve the wear of the screw rod. If it is exposed to the outside for a long time, the casing should be used for certain protective facilities to reduce the rain erosion and external non-human factors damage.
