在今天的智能传动中，机床与我们息息相关。以滚珠丝杠为例，它占据了自动机械的主要位置，带动了机械的转动，提高了产品的质量保证。想必用过直线导轨元部件的朋友都知道，在设计的时候需要遵循几点原则才能够达到如此精密的效果。下面导轨丝杠厂家为您解说下。

In today's intelligent transmission, machine tools are closely related to us. Take the ball screw as an example, it occupies the main position of the automatic machinery, drives the rotation of the machinery, and improves the quality assurance of the product. It must be known to all friends who have used linear guide elements that several principles should be followed in design to achieve such a precise effect. The manufacturer of guide rail lead screw will explain for you.

滚珠丝杠的四大禁止项：

Four prohibitions of ball screw:

1、严禁滚珠丝杠承受径向载荷或螺母承受倾覆力矩。

1. It is strictly prohibited that the ball screw bears radial load or the nut bears overturning torque.

2、严禁在超过转速的情况下使用。在高速进给过程中，应实际计算滚珠丝杠副的可用转速。

2. It is forbidden to use it when the rotating speed is exceeded. In the process of high-speed feeding, the available speed of the ball screw pair should be actually calculated.

3、严禁忽视刚度校核。适当的刚度直接影响系统的使用寿命，定位精度高和可靠性可以起到决定性的作用。

3. It is strictly forbidden to ignore the stiffness check. Proper stiffness directly affects the service life of the system, and high positioning accuracy and reliability can play a decisive role.

4、严禁在脱离防护罩的保护下直接放置在铁屑、灰尘较多的恶劣环境中使用。以免影响整个滚珠丝杠的过度损耗。

4. It is strictly forbidden to use it in a harsh environment with lots of iron filings and dust without the protection of the protective cover. So as not to affect the excessive loss of the whole ball screw.

滚珠丝杠四大必须项：

Four major requirements of ball screw:

1、必须仔细选择滚珠丝杠副的支承方式，选择不当将直接影响丝杠的定位精度和使用寿命。

1. The bearing mode of the ball screw pair must be carefully selected. Improper selection will directly affect the positioning accuracy and service life of the ball screw.

2、必须根据需要选择适当的导程精度，导程精度超出实际部分需要的，容易造成经济上的浪费，导程精度达不到实际上的需求，则会导致更大的整机损失。

2. Appropriate lead accuracy must be selected according to the needs. If the lead accuracy exceeds the actual part, it is easy to cause economic waste. If the lead accuracy does not meet the actual requirements, it will lead to greater overall loss.

3、要充分考虑滚珠丝杠副与周边零件的装配与拆卸关系，避免滚珠丝杠在装配与拆卸过程中发生损耗，在将滚珠螺母从丝杆轴上拆下来时需要留意周边联结设计。

3. The assembly and disassembly relationship between the ball screw pair and the surrounding parts should be fully considered to avoid the loss of the ball screw during the assembly and disassembly process. When removing the ball nut from the screw shaft, attention should be paid to the peripheral connection design.

4、在设必须保持适当的行程余量，或是加装限位装置以保证螺母轴段不会超出螺纹部分而导致丝杆的损坏，严重时将直接造成丝杆完全报废。

4. During the design, appropriate stroke allowance must be maintained, or a limit device must be installed to ensure that the nut shaft section will not exceed the threaded part, which will lead to the damage of the screw rod. In serious cases, the screw rod will be completely scrapped.

一般情况，丝杆的直径也取决于承载物的重量和尺寸，如果承载重量和尺寸没有太大偏差，导轨的宽度比丝杠的直径略大既可。一般情况下丝杠直径20毫米配23毫米宽的导轨，直径16毫米的丝杠配20毫米宽的导轨。更多相关内容就来我们网站http://www.jngongrun.com咨询吧！

Generally, the diameter of the lead screw also depends on the weight and size of the load. If there is no big deviation between the weight and size of the load, the width of the guide rail can be slightly larger than the diameter of the lead screw. Generally, the lead screw with a diameter of 20 mm is equipped with a guide rail with a width of 23 mm, and the lead screw with a diameter of 16 mm is equipped with a guide rail with a width of 20 mm.
