The ball screw includes cage or recirculating ball elements to achieve linear motion. They operate at 90% lower efficiency, have a predictable life, and generate less heat even during long periods of use. They are ideal for 100% duty cycle applications and high speed applications.

權(quán)衡是滾珠絲杠致動器。如果用于垂直應(yīng)用，則需要制動。循環(huán)球也會產(chǎn)生大量的可聽噪音?？梢灶A(yù)加載滾珠絲杠執(zhí)行器，以提供應(yīng)用所需的響應(yīng)性。為了降低絲杠磨損，延長絲桿的使用壽命，合理的為絲桿做潤滑保護是非常必要的。

The tradeoff is the ball screw actuator. If used for vertical applications, braking is required. The recycle ball also produces a lot of audible noise. Ball screw actuators can be preloaded to provide the responsiveness required for the application. In order to reduce the wear of the screw and prolong the service life of the screw, it is very necessary to make reasonable lubrication protection for the screw.

滾珠絲桿的潤滑可選潤滑脂或潤滑油方式，而潤滑方法大致分為手動潤滑與自動強制潤滑兩種，可依照系統(tǒng)的運行速度，使用環(huán)境等需求做適合的選擇有的環(huán)境可以使用鉬系等固體材料作為潤滑劑。詳情可以咨詢廣東索科潤滑油技術(shù)部。

Ball screw can be lubricated by grease or lubricating oil, and the lubrication method can be roughly divided into manual lubrication and automatic forced lubrication. The suitable choice can be made according to the running speed of the system and the use environment. Some environments can use solid materials such as molybdenum series as lubricating agent. For details, please refer to Guangdong Soko lubricant technology department.

通過油潤滑，應(yīng)用條件足以形成彈性流體動力學（EHD）潤滑膜也是關(guān)重要的。該薄膜將承載滾珠與滾道分開，防止金屬與金屬接觸。確定潤滑膜是否有三個主要條件：潤滑劑的粘度，螺桿的速度以及滾珠和滾道之間的壓力。

Through oil lubrication, it is also essential that the application conditions are sufficient to form an EHD lubricating film. The film separates the bearing ball from the raceway to prevent metal to metal contact. There are three main conditions to determine whether the lubricating film is formed: the viscosity of the lubricant, the speed of the screw and the pressure between the ball and the raceway.

由于速度對EHD潤滑的影響，低速應(yīng)用通常需要潤滑脂，在邊界潤滑（主要是金屬與金屬的接觸）或混合潤滑（金屬與金屬的接觸和組合）的條件下提供更好的潤滑支持。

Due to the influence of speed on EHD lubrication, grease is usually required for low-speed applications to provide better lubrication support under boundary lubrication (mainly metal to metal contact) or mixed lubrication (metal to metal contact and combination).

絲桿所使用的潤滑劑，其粘度30~40cst(40℃）滑油使用ISO等級32~100，潤滑脂的給脂頻率根據(jù)使用條件與環(huán)境而有所不同，一般情形建議每運100KM的距離補充潤滑脂一次。

The viscosity of the lubricant used for the screw rod is 30 ~ 40cst (40 ℃) and the lubricating oil is of ISO grade 32 ~ 100. The frequency of grease feeding varies according to the service conditions and environment. Generally, it is recommended to add grease every 100km.
