滾珠絲杠副設(shè)計(jì)和選型時(shí)，我們需要考慮很多參數(shù)。運(yùn)行負(fù)荷、速度、精度，環(huán)境和功率要求在設(shè)計(jì)標(biāo)準(zhǔn)中都是十分重要的條件。無論設(shè)計(jì)工程師是要選擇軋制滾珠絲杠還是精密磨削滾珠絲杠，都建議充分考慮潤滑劑因素。選用適當(dāng)?shù)臐櫥瑒┛梢詼p少摩擦、降低摩擦扭矩，提高絲杠的效率，并延長使用壽命。滾珠絲杠之所以可以保持低摩擦優(yōu)勢，是通過利用潤滑劑降低滾珠和滾道面之間的滾動(dòng)阻力以及臨近滾珠間的滑動(dòng)摩擦力來實(shí)現(xiàn)的。

In the design and selection of ball screw, we need to consider many parameters. Operating load, speed, accuracy, environment and power requirements are very important conditions in the design standard. Whether the design engineer chooses rolling ball screw or precision grinding ball screw, the lubricant factor must be fully considered. The friction efficiency of the screw can be reduced and the friction life can be prolonged by using the lubricant. The reason why ball screw can keep the advantage of low friction is to reduce the rolling resistance between the ball and the raceway surface and the sliding friction force between the adjacent balls.

進(jìn)行潤滑和補(bǔ)充潤滑之前，建議對滾珠絲杠副進(jìn)行有效的清潔，以清除所有的污染物。污染物是造成滾珠絲杠過早失效的一個(gè)主要原因。正確的潤滑可以避免大多數(shù)污染物進(jìn)入絲杠螺母中，這大大降低了外部污染物可能會(huì)造成的損害。滾珠絲杠組件在運(yùn)輸和儲(chǔ)存的過程中一般使用了防銹油，在使用更終選用的潤滑劑之前，應(yīng)該完全擦掉防銹油。

Before lubrication and supplementary lubrication, the ball screw pair must be thoroughly cleaned to remove all contaminants. Contamination is one of the main reasons for premature failure of ball screw. Proper lubrication prevents most contaminants from entering the screw nut, which greatly reduces the damage that may be caused by external contaminants. Anti rust oil is generally used in the process of transportation and storage of ball screw assembly. Before using the final lubricant, the antirust oil should be completely wiped off.

A variety of methods can be used to add lubricant to the ball screw pair and keep the lubricant in the nut. For example, when grease lubrication is used, grease is added into the nut through the grease injection hole on the nut body or nut flange plate, and there are wiper blades or sealing rings at both ends of the nut to prevent grease overflow and external pollutants from entering the nut; when using oil lubrication, a set of lubrication device with pump and filtration system is needed, and the oil injection method should be considered

為滾珠絲杠副選擇合適的潤滑油或潤滑脂可以減少維修停機(jī)時(shí)間，可以使產(chǎn)品達(dá)到設(shè)計(jì)使用壽命。

Choosing the right lubricating oil or grease for ball screw pair can reduce the maintenance downtime and make the product reach the design service life.
