滚珠丝杠仅用于承受轴向负荷，作用于滚珠丝杠的径向力、弯矩会使滚珠丝杠产生附加表面接触应力等负荷，能加剧滚珠丝杠与丝杠之间的摩擦，降低其使用寿命，也可以造成丝杠的性损坏。因此，安装滚珠丝杠时，要注意一些事项。下面导轨丝杠厂家为您分析：

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:

滚珠丝杠的轴线必须和与之配套导轨的轴线平行，平行度误差≤0.05mm，机床两端支撑滚珠丝杠的轴承座孔与螺母座孔，三点必须成一线。

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.

滚珠丝杠的螺母与机床上的螺母坐进行安装时，应尽量靠近滚珠丝杠的支撑轴承端。通常情况下采用整体式安装，不要把螺母从丝杠上卸下来。特殊情况下，必须螺母卸下时，必须使用滚珠丝杠拆卸辅助轴，否则卸装时滚珠极易散落。

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.

螺母装卸时也需要注意一些事项，辅助轴大直径应该小于滚珠丝杠底径的0.1-0.3mm，辅助轴在使用时应该靠近丝杠螺纹轴肩，卸装时，旋转螺母时，勿用力过大，以避免螺母滚道或流动体；滚珠丝杠安装时必须要避免过分的撞击。

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.

当螺母出现散落后安装需要注意的是，安装前，必须认真做好各装配件的清洁工作，在装配挡住器或反向器时，注意滚珠进口出口与螺旋槽相切的孔同螺旋槽准确圆滑的衔接，使滚珠顺利进行进口及回程滚道。

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.

螺母上的螺旋回程滚道也必须与两个切向孔衔接好，保证滚珠在运行时不产生撞击、卡珠或随同产生滑动摩擦等不良现象。

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.

挡珠器或反向器在装配时，不能与螺母的滚道发生接触，为了使滚珠顺利进行工作还要保证滚珠接触的端部具有正确的形状和位置，滚珠丝杠在传递精确的运动时，可以调到一定过盈量而上有较好的接触刚度。以提高其轴向精度，并使其在整个行程中的摩擦阻力保持基本一致，没有局部过紧现象。安装调整完成后，加注机械油或主轴油，油脂可以用锂基油脂。

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.

滚珠丝杠的维护也是必不可少的，滚珠丝杠的防护装置，滚珠丝杠在使用过程，是严禁灰尘或切屑污物进入，因此必须装有防护装置；滚珠丝杠在机床上外露，应采用封闭的防护罩，如采用螺旋弹簧钢带套管，伸缩套管以及折叠式套管等。

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.

安装时，将防护罩的一端链接在滚珠螺母侧面，另一端固定在滚珠丝杠的支撑坐上。滚珠丝杠位于隐蔽位置，采用密封圈防护，密封圈装在螺母的两端，接触式和非接触式两种密封圈。更多相关事项就来我们网站http://www.jngongrun.com咨询！

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.
