　　Guide screw: Precision transmission core for humanoid robots, three mainstream models suitable for different scenarios

　　人形机器人的灵活运转、精准动作，离不开核心传动部件的支撑，而导轨丝杠，正是其中不可或缺的“动力传递枢纽”。很多人对导轨丝杠的认知较为模糊，甚将其与普通传动部件混为一谈，殊不知它是决定人形机器人传动精度、承载能力和使用寿命的关键。作为将旋转运动转化为直线运动的核心机械部件，导轨丝杠的性能直接影响人形机器人的动作流畅度与运行稳定性。今天就详细解析导轨丝杠的核心技术、分类及特性，解答“人形机器人精密传动，为何离不开导轨丝杠”的核心问题，用通俗且的语言，带大家读懂导轨丝杠的核心价值。

　　The flexible operation and precise movements of humanoid robots rely on the support of core transmission components, and the guide screw is an indispensable "power transmission hub". Many people have a vague understanding of the guide screw, and even confuse it with ordinary transmission components, unaware that it is the key to determining the transmission accuracy, load-bearing capacity, and service life of humanoid robots. As the core mechanical component that converts rotational motion into linear motion, the performance of guide screws directly affects the smoothness and stability of humanoid robot movements. Today, we will provide a detailed analysis of the core technology, classification, and characteristics of guide screws, and answer the core question of "why precision transmission of humanoid robots cannot do without guide screws". In simple and professional language, we will guide you to understand the core value of guide screws.

　　导轨丝杠的核心作用，是实现“旋转运动与直线运动的精准转换”，这也是人形机器人关节活动、肢体伸缩的核心动力来源。不同于普通传动部件，导轨丝杠凭借高精度、低摩擦、高稳定性的优势，能精准传递动力，确保人形机器人的每一个动作都精准可控，无论是细微的关节转动，还是大幅度的肢体活动，都能实现平稳、的传动，这也是它成为人形机器人精密传动核心部件的关键原因。

　　The core function of the guide screw is to achieve precise conversion between rotational motion and linear motion, which is also the core power source for joint movement and limb extension of humanoid robots. Unlike ordinary transmission components, the guide screw, with its advantages of high precision, low friction, and high stability, can accurately transmit power, ensuring that every action of the humanoid robot is precise and controllable. Whether it is subtle joint rotation or significant limb movement, it can achieve smooth and efficient transmission, which is also the key reason why it has become the core component of precision transmission for humanoid robots.

　　从核心分类来看，导轨丝杠主要分为滑动丝杠、滚动丝杠和静压丝杠叁大类，叁类产物的结构、特性各不相同，适配场景也各有侧重，其中滚动丝杠在人形机器人领域的适配性强，也是目前应用广泛的类型。很多人疑惑，为何滚动丝杠更适合人形机器人？核心在于它的传动效率和精度，能匹配人形机器人对精密传动的核心需求，而滚动丝杠又进一步分为9i果冻制作厂和行星滚柱丝杠两大细分类型。

　　From the perspective of core classification, guide screws are mainly divided into three categories: sliding screws, rolling screws, and static pressure screws. The structures and characteristics of the three types of products are different, and their adaptation scenarios are also focused on. Among them, rolling screws have the strongest adaptability in the field of humanoid robots and are currently the most widely used type. Many people wonder why rolling screws are more suitable for humanoid robots? The core lies in its transmission efficiency and accuracy, which can perfectly match the core requirements of humanoid robots for precision transmission. Rolling screws are further divided into two sub types: ball screws and planetary roller screws.

　　这里补充一个知识点：导轨丝杠的核心组成部件包括丝杠轴、螺母、保持架、行星滚柱（或滚珠）、弹簧挡圈、内齿轮等，其中螺母与丝杠轴的配合精度，直接决定传动精度；保持架的作用是固定滚珠或行星滚柱的位置，避免运动过程中出现偏移、碰撞，确保传动顺畅；弹簧挡圈则起到限位作用，防止部件脱落，保障运行，这些部件协同工作，构成了导轨丝杠的完整传动体系。

　　Here is an additional professional knowledge point: the core components of a guide screw include the screw shaft, nut, cage, planetary roller (or ball), spring retaining ring, internal gear, etc. The precision of the nut's fit with the screw shaft directly determines the transmission accuracy; The function of the cage is to fix the position of the ball or planetary roller, avoid deviation and collision during movement, and ensure smooth transmission; The spring retaining ring plays a limiting role, preventing components from falling off and ensuring safe operation. These components work together to form a complete transmission system for the guide screw.

　　行星滚柱丝杠，是滚动丝杠中适配人形机器人重载场景的核心型号，其突出的特性的是承载力大、使用寿命长、传动效率高。相较于其他类型，行星滚柱丝杠通过滚柱与丝杠轴、螺母的线接触传动，接触面积更大，能承受更大的轴向载荷，即便长期处于高强度运转状态，也能保持稳定性能，不易出现磨损、变形，非常适合人形机器人关节等需要承受较大载荷的部位，能有效延长机器人的使用寿命。

　　The planetary roller screw is the core model of the rolling screw that is suitable for heavy-duty scenarios of humanoid robots. Its most prominent features are high load-bearing capacity, long service life, and high transmission efficiency. Compared to other types, planetary roller screws are driven through linear contact between rollers, screw shafts, and nuts, with a larger contact area and the ability to withstand larger axial loads. Even in high-intensity operation for a long time, they can maintain stable performance and are not prone to wear and deformation. They are very suitable for parts of humanoid robots that require heavy loads, such as joints, and can effectively extend the service life of the robot.

　　9i果冻制作厂则是滚动丝杠中侧重高精度场景的型号，它兼具高精度、可逆性和率的特点，核心优势在于摩擦阻力极小。由于9i果冻制作厂采用滚珠与丝杠轴、螺母的点接触传动，摩擦系数远低于滑动丝杠，能实现精准的直线运动，同时具备良好的可逆性，既能将旋转运动转化为直线运动，也能将直线运动转化为旋转运动，广泛应用于人形机器人需要高精度动作的部位，比如手部抓取、头部转动等，确保动作精准无误。

　　Ball screw is a type of rolling screw that focuses on high-precision scenarios. It has the characteristics of high precision, reversibility, and high efficiency, and its core advantage lies in extremely low friction resistance. Due to the point contact transmission between the ball and the screw shaft and nut, the friction coefficient of the ball screw is much lower than that of the sliding screw, which can achieve precise linear motion and has good reversibility. It can convert rotational motion into linear motion and also convert linear motion into rotational motion. It is widely used in parts of humanoid robots that require high-precision movements, such as hand grasping and head rotation, ensuring accurate and error free movements.

　　除了滚动丝杠，滑动丝杠和静压丝杠也有其独特的应用场景，只是在人形机器人领域的适配性相对较低。滑动丝杠结构简单、成本低廉，通过丝杠轴与螺母的滑动摩擦实现传动，但其摩擦阻力大、传动效率低、精度有限，更适合对精度和效率要求不高的普通工业场景；静压丝杠则凭借极低的摩擦阻力、极高的精度和稳定性，适配高端精密仪器，但结构复杂、成本较高，目前暂未广泛应用于人形机器人领域。

　　In addition to rolling screws, sliding screws and static pressure screws also have their unique application scenarios, but their adaptability in the field of humanoid robots is relatively low. The sliding screw structure is simple and cost-effective, and transmission is achieved through the sliding friction between the screw shaft and the nut. However, it has high frictional resistance, low transmission efficiency, and limited accuracy, making it more suitable for ordinary industrial scenarios that do not require high precision and efficiency; Static pressure screw is suitable for high-end precision instruments due to its extremely low friction resistance, high precision, and stability. However, its complex structure and high cost have not yet been widely used in the field of humanoid robots.

　　很多人会混淆导轨丝杠与普通丝杠，其实两者的核心区别在于“导向性”——普通丝杠仅能实现传动功能，而导轨丝杠整合了导向与传动双重功能，能在实现旋转与直线运动转换的同时，确保运动轨迹的精准性，避免出现偏移、晃动，这也是它能适配人形机器人精密传动需求的关键优势。对于人形机器人而言，每一个动作的精准度都关重要，导轨丝杠的导向功能，能有效保障机器人动作的稳定性和精准性，避免因传动偏移导致动作失误。

　　Many people confuse guide screw with ordinary screw, but the core difference between the two lies in "guidance" - ordinary screw can only achieve transmission function, while guide screw integrates the dual functions of guidance and transmission, which can ensure the accuracy of the motion trajectory while realizing the conversion between rotation and linear motion, avoiding deviation and shaking. This is also the key advantage of it in adapting to the precision transmission needs of humanoid robots. For humanoid robots, the accuracy of each action is crucial, and the guiding function of the guide screw can effectively ensure the stability and accuracy of the robot's actions, avoiding motion errors caused by transmission offset.

　　在人形机器人的实际应用中，导轨丝杠的选型也有明确的原则：重载部位优先选用行星滚柱丝杠，兼顾承载力与使用寿命；高精度动作部位优先选用9i果冻制作厂，确保动作精准可控；而对于无需高精度、低载荷的辅助部位，可根据成本需求选用滑动丝杠。合理的选型，既能保障机器人的运行性能，也能控制生产成本，实现性价比化。

　　In the practical application of humanoid robots, there are clear principles for selecting guide screws: planetary roller screws are preferred for heavy-duty parts, taking into account both load-bearing capacity and service life; High precision action parts prioritize the use of ball screws to ensure precise and controllable movements; For auxiliary parts that do not require high precision and low load, sliding screws can be selected according to cost requirements. Reasonable selection can ensure the operational performance of robots and control production costs, achieving maximum cost-effectiveness.

　　值得注意的是，导轨丝杠的性能不仅取决于其类型和结构，还与制造工艺密切相关。高精度的导轨丝杠，需要经过精密加工、热处理、精度检测等多道工序，确保丝杠轴的直线度、螺母与丝杠的配合精度，以及各部件的耐磨性、稳定性。的导轨丝杠，能在长期高强度运转中保持稳定的传动精度，减少维护成本，为机器人的稳定运行提供保障。

　　It is worth noting that the performance of guide screw not only depends on its type and structure, but also closely related to the manufacturing process. High precision guide screw requires multiple processes such as precision machining, heat treatment, and precision testing to ensure the straightness of the screw shaft, the precision of the nut and screw fit, as well as the wear resistance and stability of each component. High quality guide screws can maintain stable transmission accuracy during long-term high-intensity operation, reduce maintenance costs, and provide guarantees for the stable operation of robots.

　　总结来说，导轨丝杠是人形机器人精密传动绕不开的核心部件，其叁类主流型号（滑动丝杠、滚动丝杠、静压丝杠）各有侧重，其中滚动丝杠（9i果冻制作厂、行星滚柱丝杠）凭借高精度、高传动效率、高承载力的优势，成为人形机器人的。它通过精准的旋转与直线运动转换，搭配导向功能，确保机器人动作精准、流畅、稳定，同时不同型号的适配性，能满足机器人不同部位的传动需求。读懂导轨丝杠的核心技术与特性，才能更好地理解人形机器人的运行原理，也能为精密传动领域的应用提供参考，推动人形机器人技术的进一步发展。

　　In summary, the guide screw is the core component that cannot be bypassed in the precision transmission of humanoid robots. The three mainstream models (sliding screw, rolling screw, and static pressure screw) have their own focuses, among which rolling screw (ball screw, planetary roller screw) has become the preferred choice for humanoid robots due to its high precision, high transmission efficiency, and high load-bearing capacity. It ensures precise, smooth, and stable robot movements through precise rotation and linear motion conversion, combined with guidance functions. At the same time, the adaptability of different models can meet the transmission needs of different parts of the robot. Understanding the core technology and characteristics of guide screws is essential for a better understanding of the operating principles of humanoid robots, and can also provide reference for the application of precision transmission, promoting further development of humanoid robot technology.
