滾珠絲杠包括堅(jiān)持架式或循環(huán)滾珠元件，以完成線性運(yùn)動(dòng)。它們的工作效率降低了90%，壽命可預(yù)測(cè)，即便在長(zhǎng)時(shí)間運(yùn)用中也能產(chǎn)生更少的熱量。它們是100%占空比應(yīng)用和高速應(yīng)用的理想選擇。取舍是滾珠絲杠執(zhí)行器。假如用于垂直應(yīng)用，則需求制動(dòng)。循環(huán)球也會(huì)產(chǎn)生很多可聽(tīng)的噪音。滾珠絲杠執(zhí)行器能夠預(yù)加載，以提供所需的運(yùn)用響應(yīng)。為了減少磨損，延長(zhǎng)螺桿的運(yùn)用壽命，必需堅(jiān)持螺桿的平穩(wěn)。

　　The ball screw consists of a stick or recirculating ball element for linear motion. Their efficiency is reduced by 90%, their life is predictable, and they can generate less heat even in long-term use. They are ideal for 100% duty cycle applications and high-speed applications. The trade-off is the ball screw actuator. If used for vertical applications, braking is required. The recirculating ball also produces a lot of audible noise. Ball screw actuators can be preloaded to provide the required operational response. In order to reduce the wear and prolong the service life of the screw, it is necessary to adhere to the stability of the screw.

　　滾珠絲桿的潤(rùn)滑可選潤(rùn)滑脂或潤(rùn)滑油方式，而潤(rùn)滑方法大致分為手動(dòng)潤(rùn)滑與自動(dòng)強(qiáng)迫潤(rùn)滑兩種，可依照系統(tǒng)的運(yùn)轉(zhuǎn)速度，運(yùn)用環(huán)境等需求做適宜的選擇有的環(huán)境可以運(yùn)用鉬系等固體材料作為潤(rùn)滑劑。詳情可以咨詢廣東索科潤(rùn)滑油技術(shù)部。

　　The ball screw can be lubricated by grease or oil, and the lubrication method can be roughly divided into manual lubrication and automatic forced lubrication. According to the operating speed of the system, the application environment and other requirements, the appropriate choice can be made. In some environments, molybdenum system and other solid materials can be used as lubricating agent. For details, please consult Guangdong Soko lubricating oil technology department.

　　經(jīng)過(guò)油潤(rùn)滑，應(yīng)用條件足以構(gòu)成彈性流體動(dòng)力學(xué)（EHD）潤(rùn)滑膜也是關(guān)重要的。該薄膜將承載滾珠與滾道分開(kāi)，防止金屬與金屬接觸。肯定潤(rùn)滑膜能否有三個(gè)主要條件：潤(rùn)滑劑的粘度，螺桿的速度以及滾珠和滾道之間的壓力。由于速度對(duì)EHD潤(rùn)滑的影響，低速應(yīng)用通常需求潤(rùn)滑脂，在邊境潤(rùn)滑（主要是金屬與金屬的接觸）或混合潤(rùn)滑（金屬與金屬的接觸和組合）的條件下提供更好的潤(rùn)滑支持。

　　After oil lubrication, the application conditions are enough to form EHD lubricating film. The film separates the bearing ball from the raceway to prevent metal to metal contact. There are three main conditions to confirm the lubrication film: the viscosity of lubricant, the speed of screw and the pressure between ball and raceway. Due to the influence of speed on EHD lubrication, low-speed applications usually require grease to provide better lubrication support under the conditions of boundary lubrication (mainly metal to metal contact) or mixed lubrication (metal to metal contact and combination).

　　絲桿所運(yùn)用的潤(rùn)滑劑，其粘度30~40cst(40℃）滑油運(yùn)用ISO等級(jí)32~100，潤(rùn)滑脂的給脂頻率根據(jù)運(yùn)用條件與環(huán)境而有所不同，普通情形建議每運(yùn)100KM的距離補(bǔ)充潤(rùn)滑脂一次。

　　The lubricant used for the screw rod has a viscosity of 30-40 CST (40 ℃) and an ISO grade of 32-100. The grease feeding frequency varies according to the application conditions and environment. In general, it is recommended to supplement the grease once every 100 km.
