In the vast and complex mechanical systems of the industrial field, the guide screw, as the core component for achieving precise linear motion, is like a cornerstone of a building, supporting the efficient operation of various advanced equipment. It continues to drive the continuous development of manufacturing and automation fields with its simple and exquisite design, playing an irreplaceable key role in the process of industrial development.

设计理念的变革与突破​

The transformation and breakthrough of design concepts

早期的导轨丝杠设计侧重于满足基本的运动需求，结构较为简单。但随着工业技术朝着高精度、高速度、高负载方向迈进，设计理念发生了根本性变革。现代导轨丝杠设计充分考虑了材料特性、力学原理以及摩擦学等多学科知识。在材料选择上，高强度、轻量化且具备良好耐磨性能的合金材料成为主流。例如，航空航天领域使用的导轨丝杠常采用钛合金材质，在减轻重量的同时保证了极高的强度，以适应飞行器严苛的工作环境。​

Early guide screw designs focused on meeting basic motion needs and had a relatively simple structure. But as industrial technology advances towards high precision, high speed, and high load, the design concept has undergone fundamental changes. Modern guide screw design fully considers multidisciplinary knowledge such as material properties, mechanical principles, and tribology. In terms of material selection, alloy materials with high strength, lightweight, and good wear resistance have become mainstream. For example, the guide screws used in the aerospace industry are often made of titanium alloy material, which reduces weight while ensuring extremely high strength to adapt to the harsh working environment of aircraft. ​

同时，为了降低摩擦、提高传动效率，工程师们不断优化丝杠螺纹形状与导轨的接触方式。新型的滚珠丝杠采用了独特的循环滚珠结构，减少了滚珠与丝杠、螺母之间的摩擦阻力，实现了更高的传动效率与定位精度。而导轨设计也从传统的滑动导轨逐渐向滚动导轨、静压导轨等多元化方向发展。滚动导轨利用滚动体实现低摩擦运动，适合高速、高精度场景；静压导轨则通过在导轨面之间形成静压油膜，极大地提高了承载能力与运动平稳性，常用于大型重载设备。

At the same time, in order to reduce friction and improve transmission efficiency, engineers continuously optimize the contact between the screw thread shape and the guide rail. The new type of ball screw adopts a unique circulating ball structure, reducing the frictional resistance between the ball and the screw and nut, achieving higher transmission efficiency and positioning accuracy. And the design of guide rails has gradually evolved from traditional sliding guides to diversified directions such as rolling guides and static pressure guides. Rolling rails utilize rolling elements to achieve low friction motion, suitable for high-speed and high-precision scenarios; Static pressure guide rails greatly improve the load-bearing capacity and motion stability by forming a static pressure oil film between the guide rail surfaces, and are commonly used in large heavy-duty equipment.

故障诊断的新兴技术与方法​

Emerging technologies and methods for fault diagnosis

导轨丝杠在长期运行过程中，难免会出现故障，影响设备正常运行。传统的故障诊断主要依赖人工经验，通过观察设备运行时的异常声音、振动以及丝杠表面磨损情况等来判断故障。但这种方式主观性强、准确性低，且难以在早期发现潜在故障。如今，随着信息技术与数据分析技术的发展，导轨丝杠故障诊断迎来了新的契机。​

During long-term operation, it is inevitable that the guide screw will malfunction, affecting the normal operation of the equipment. Traditional fault diagnosis mainly relies on manual experience, by observing abnormal sounds, vibrations, and surface wear of the screw during equipment operation to determine faults. However, this approach is subjective, has low accuracy, and is difficult to detect potential faults in the early stages. Nowadays, with the development of information technology and data analysis technology, the diagnosis of guide screw faults has ushered in a new opportunity. ​

振动分析法成为常用的故障诊断手段之一。通过在导轨丝杠关键部位安装振动传感器，实时采集设备运行时的振动信号。这些信号经过放大、滤波等处理后，利用傅里叶变换等数学方法进行频谱分析。不同类型的故障，如滚珠磨损、丝杠弯曲、导轨松动等，会产生特定频率特征的振动信号。通过对比正常与故障状态下的频谱数据，就能准确判断故障类型与发生位置。​

Vibration analysis has become one of the commonly used fault diagnosis methods. By installing vibration sensors at key parts of the guide screw, real-time vibration signals during equipment operation can be collected. After amplification, filtering, and other processing, these signals are subjected to spectral analysis using mathematical methods such as Fourier transform. Different types of faults, such as ball wear, screw bending, and loose guide rails, can generate vibration signals with specific frequency characteristics. By comparing the spectrum data under normal and fault conditions, the type and location of the fault can be accurately determined. ​

此外，基于大数据与人工智能的故障诊断系统也逐渐兴起。该系统收集大量导轨丝杠在不同工况下的运行数据，包括温度、压力、电流等参数。当系统监测到实时数据偏离正常范围时，模型能够提前预测可能出现的故障，并发出预警，为设备维护人员争取充足的维修时间，避免因突发故障导致的生产中断。

In addition, fault diagnosis systems based on big data and artificial intelligence are gradually emerging. This system collects a large amount of operational data of guide screws under different working conditions, including parameters such as temperature, pressure, and current. When the system detects that real-time data deviates from the normal range, the model can predict possible faults in advance and issue warnings, which can buy sufficient repair time for equipment maintenance personnel and avoid production interruptions caused by sudden failures.
