滾珠絲杠僅用于承受軸向負荷，作用于滾珠絲杠的徑向力、彎矩會使滾珠絲杠產生附加表面接觸應力等負荷，能加劇滾珠絲杠與絲杠之間的摩擦，降低其使用壽命，也可以造成絲杠的性損壞。因此，安裝滾珠絲杠時，要注意一些事項。下面導軌絲杠廠家為您分析：

The ball screw is only used to withstand axial loads. The radial force and bending moment acting on the ball screw will cause additional surface contact stress and other loads, which can intensify the friction between the ball screw and the screw, reduce its service life, and also cause permanent damage to the screw. Therefore, when installing the ball screw, some precautions should be taken. The manufacturer of the guide rail screw will analyze for you:

滾珠絲杠的軸線必須和與之配套導軌的軸線平行，平行度誤差≤0.05mm，機床兩端支撐滾珠絲杠的軸承座孔與螺母座孔，三點必須成一線。

The axis of the ball screw must be parallel to the axis of the supporting guide rail, with a parallelism error of ≤ 0.05mm. The center of the bearing seat hole supporting the ball screw at both ends of the machine tool must be aligned with the center of the nut seat hole.

滾珠絲杠的螺母與機床上的螺母坐進行安裝時，應盡量靠近滾珠絲杠的支撐軸承端。通常情況下采用整體式安裝，不要把螺母從絲杠上卸下來。特殊情況下，必須螺母卸下時，必須使用滾珠絲杠拆卸輔助軸，否則卸裝時滾珠極易散落。

When installing the nut of the ball screw and the nut on the machine tool, it should be as close as possible to the supporting bearing end of the ball screw. Usually, it is installed as a whole and do not remove the nut from the screw. In special circumstances, when the nut must be removed, a ball screw must be used to remove the auxiliary shaft, otherwise the balls are easily scattered during disassembly.

螺母裝卸時也需要注意一些事項，輔助軸大直徑應該小于滾珠絲杠底徑的0.1-0.3mm，輔助軸在使用時應該靠近絲杠螺紋軸肩，卸裝時，旋轉螺母時，勿用力過大，以避免螺母滾道或流動體；滾珠絲杠安裝時必須要避免過分的撞擊。

When loading and unloading nuts, it is also necessary to pay attention to some precautions. Firstly, the large diameter of the auxiliary shaft should be less than 0.1-0.3mm of the bottom diameter of the ball screw. The auxiliary shaft should be close to the shoulder of the screw thread during use. When unloading and rotating the nut, do not use too much force to avoid the nut raceway or flow body; When installing the ball screw, excessive impact must be avoided.

當螺母出現散落后安裝需要注意的是，安裝前，必須認真做好各裝配件的清潔工作，在裝配擋住器或反向器時，注意滾珠進口出口與螺旋槽相切的孔同螺旋槽準確圓滑的銜接，使滾珠順利進行進口及回程滾道。

When the nuts are scattered during installation, it is important to carefully clean the assembly parts before installation. When assembling the stopper or reverser, pay attention to the accurate and smooth connection between the holes at the inlet and outlet of the ball and the spiral groove, so that the ball can smoothly enter and return the raceway.

螺母上的螺旋回程滾道也必須與兩個切向孔銜接好，保證滾珠在運行時不產生撞擊、卡珠或隨同產生滑動摩擦等不良現象。

The screw return raceway on the nut must also be connected with the two tangential holes to ensure that the ball will not produce impact, ball jam or sliding friction during operation.

擋珠器或反向器在裝配時，不能與螺母的滾道發生接觸，為了使滾珠順利進行工作還要保證滾珠接觸的端部具有正確的形狀和位置，滾珠絲杠在傳遞精確的運動時，可以調到一定過盈量而上有較好的接觸剛度。以提高其軸向精度，并使其在整個行程中的摩擦阻力保持基本一致，沒有局部過緊現象。安裝調整完成后，加注機械油或主軸油，油脂可以用鋰基油脂。

During assembly, the ball stopper or reverser should not come into contact with the raceway of the nut. In order to ensure the smooth operation of the ball, it is necessary to ensure that the end of the ball contact has the correct shape and position. The ball screw can be adjusted to a certain amount of interference and has good contact stiffness when transmitting precise motion. To improve its axial accuracy and ensure that its frictional resistance remains basically consistent throughout the entire stroke, without local over tightening. After installation and adjustment, add mechanical oil or spindle oil, which can be lithium based grease.

滾珠絲杠的維護也是必不可少的，滾珠絲杠的防護裝置，滾珠絲杠在使用過程，是嚴禁灰塵或切屑污物進入，因此必須裝有防護裝置；滾珠絲杠在機床上外露，應采用封閉的防護罩，如采用螺旋彈簧鋼帶套管，伸縮套管以及折疊式套管等。

The maintenance of the ball screw is also essential, and the protective device of the ball screw. During the use of the ball screw, it is strictly prohibited for dust or debris to enter, so protective devices must be installed; When the ball screw is exposed on the machine tool, a closed protective cover should be used, such as using spiral spring steel belt sleeves, telescopic sleeves, and foldable sleeves.

安裝時，將防護罩的一端鏈接在滾珠螺母側面，另一端固定在滾珠絲杠的支撐坐上。滾珠絲杠位于隱蔽位置，采用密封圈防護，密封圈裝在螺母的兩端，接觸式和非接觸式兩種密封圈。更多相關事項就來我們網站http://m.feicui77.cn咨詢！

During installation, connect one end of the protective cover to the side of the ball nut and fix the other end to the support seat of the ball screw. The ball screw is located in a concealed position and protected by a sealing ring. The sealing ring is installed at both ends of the nut, and there are two types of sealing rings: contact and non-contact.
