大型丝杠的性能因设计、制造、安装以及使用维护等因素而受到影响，如何降低或者控制大型丝杠的噪音，可从设计、构造、安装以及使用维护方面分析起。

The performance of large lead screws is affected by factors such as design, manufacturing, installation, and maintenance. How to reduce or control the noise of large lead screws can be analyzed from the aspects of design, construction, installation, and maintenance.

设计方面选用的材料要具有足够的强度性、耐磨性、减振性等优点。制造过程中的螺距、丝杠外圆的椭圆度，和丝杠的平衡度，螺距误差及加工过程丝杠面表面粗糙度，使加工中获得的丝杠综合质量，可以大大降低丝杠引起的噪声。

The materials selected for design should have sufficient strength, wear resistance, vibration reduction and other advantages. The pitch, ovality of the outer circle of the lead screw, balance of the lead screw, pitch error, and surface roughness of the lead screw during the manufacturing process can achieve the best overall quality of the lead screw during processing, greatly reducing the noise caused by the lead screw.

另外，安装时要保证丝杠的平衡、同心，选配零部件的同时要符合大型丝杠的精度要求。并把零部件紧固。再者，选用润滑油时，必须按照机床丝杠使用说明书来加油或者换油、选油，保证大型丝杠的工作环境的温度、湿度在额定的范围以内。

In addition, during installation, it is necessary to ensure the balance and concentricity of the lead screw, and to select components that meet the accuracy requirements of large lead screws. And tighten the components. Furthermore, when selecting lubricating oil, it is necessary to follow the machine tool screw user manual to add or change oil, and select oil to ensure that the temperature and humidity of the working environment of large screws are within the rated range.
