　　The core password for robot joints: guide screw scheme, unlocking new possibilities for agile movement

　　在机器人技术飞速迭代的今天，关节的灵活性、精准度直接决定机器人的实操能力，而导轨丝杠作为线性执行器的核心部件，正是驱动机器人关节灵活运转的“幕后功臣”。很多从事机器人研发、采购的从业者都会问：线性执行器有哪些新型导轨丝杠方案？不同方案适配哪些机器人关节？今天，就结合实际应用场景，详细拆解导轨丝杠在机器人关节中的核心应用方案，彻底解答“机器人关节线性执行器该选哪种导轨丝杠方案”这一核心问题，带大家读懂导轨丝杠如何撑起机器人关节革命。

　　In today's rapidly iterating robot technology, the flexibility and accuracy of joints directly determine the practical ability of robots, and the guide screw, as the core component of linear actuators, is the "behind the scenes hero" driving the flexible operation of robot joints. Many practitioners engaged in robot research and procurement will ask: What are the new guide screw solutions for linear actuators? Which robot joints are suitable for different schemes? Today, based on practical application scenarios, we will dissect in detail the core application scheme of guide screws in robot joints, thoroughly answering the core question of "which guide screw scheme should be selected for linear actuators in robot joints", and guiding everyone to understand how guide screws support the revolution of robot joints.

　　导轨丝杠是将旋转运动转化为直线运动的核心传动部件，被誉为机器人关节的“骨骼脉络”，其性能直接影响机器人关节的精度、负载能力与使用寿命。目前，适配机器人关节的线性执行器，核心导轨丝杠方案主要有两类，分别对应不同关节部位的使用需求，兼顾灵巧性与稳定性，其中主流的就是反向式行星滚珠丝杠方案。

　　The guide screw is the core transmission component that converts rotational motion into linear motion, and is known as the "skeleton network" of robot joints. Its performance directly affects the accuracy, load capacity, and service life of robot joints. At present, there are mainly two types of core guide screw solutions for linear actuators adapted to robot joints, which correspond to the usage needs of different joint parts and balance agility and stability. Among them, the most mainstream is the reverse planetary ball screw solution.

　　反向式行星滚珠丝杠，是机器人手脚关节的“专属适配方案”，也是目前线性执行器中应用广泛的导轨丝杠类型。它融合了行星减速器和丝杠的核心原理，通过滚珠作为传动介质，将滑动摩擦转化为滚动摩擦，传动效率高、定位精度准，同时具备结构紧凑、负载能力强的优势，适配机器人手关节、脚关节的运动需求。机器人手脚关节需要频繁做伸缩、转动动作，对精度和灵活性要求极高，反向式行星滚珠丝杠能精准控制关节的微小位移，确保动作流畅连贯，同时承受关节运动产生的负载，避免出现卡顿、偏移等问题，为机器人灵活活动提供稳定支撑。

　　Reverse planetary ball screw is an "exclusive adaptation solution" for robot hand and foot joints, and is currently the most widely used type of guide screw in linear actuators. It combines the core principles of planetary reducer and screw, using ball as the transmission medium to convert sliding friction into rolling friction, with high transmission efficiency and accurate positioning accuracy. At the same time, it has the advantages of compact structure and strong load capacity, perfectly adapting to the motion needs of robot hand joints and foot joints. The joints of the robot's hands and feet require frequent extension, rotation, and high precision and flexibility. The reverse planetary ball screw can accurately control the small displacement of the joints, ensuring smooth and coherent movements while bearing the load generated by joint movements, avoiding problems such as jamming and deviation, and providing stable support for the robot's flexible activities.

　　除了手脚关节，机器人手腕部位的灵巧运动，离不开另一类核心方案——反向式滚珠丝板。手腕关节相较于手脚关节，动作更精细、空间更紧凑，对导轨丝杠的体积、精度要求更为严苛，而反向式滚珠丝板恰好契合这一需求。它的结构更为精巧，能在狭小空间内实现精准传动，适配手腕关节的灵活转动与微调，让机器人手腕能够完成抓取、翻转等精细动作，大幅提升机器人的实操能力。目前，这类滚珠丝板已实现小型化突破，小可做到040.5规格，专门适配灵巧手等对体积、精度有要求的机器人部件，真正实现了“小身材，大作用”。

　　In addition to the joints of the hands and feet, the agile movement of the robot wrist cannot be separated from another core solution - the reverse ball screw plate. Compared to the joints of the hands and feet, the wrist joint has finer movements and more compact space, requiring more stringent requirements for the volume and accuracy of the guide screw. The reverse ball screw plate perfectly meets this requirement. Its structure is more sophisticated, enabling precise transmission in small spaces and adapting to flexible rotation and fine-tuning of wrist joints, allowing the robot wrist to perform fine actions such as grasping and flipping, greatly improving the robot's practical ability. At present, this type of ball screw plate has achieved a breakthrough in miniaturization, with a minimum specification of 040.5, specially adapted for robot components such as dexterous hands that have extreme requirements for volume and accuracy, truly realizing the concept of "small body, big function".

　　可能有人会疑惑，同样是导轨丝杠方案，反向式行星滚珠丝杠与反向式滚珠丝板有何核心区别？其实关键在于适配场景的差异：前者侧重负载能力与灵活传动，适配机器人手脚关节这类需要承受一定负载、动作幅度较大的部位；后者侧重小型化与精细传动，适配手腕、灵巧手这类动作精细、空间有限的部位，两者分工明确，共同支撑机器人关节的运转。

　　Some people may wonder, what is the core difference between reverse planetary ball screw and reverse ball screw plate for the same guide screw scheme? In fact, the key lies in the differences in adaptation scenarios: the former focuses on load capacity and flexible transmission, adapting to parts such as robot hand and foot joints that require a certain load and a large range of motion; The latter focuses on miniaturization and fine transmission, adapting to parts with fine movements and limited space such as wrists and dexterous hands. The two have clear division of labor and jointly support the comprehensive operation of robot joints.

　　作为机器人关节线性执行器的核心，这两类导轨丝杠方案的突破，彻底推动了机器人关节的“革命”。相较于传统导轨丝杠，反向式行星滚珠丝杠和反向式滚珠丝板，在精度、体积、负载能力上均有显著提升，尤其是040.5规格滚珠丝板的研发，打破了小型化导轨丝杠的技术瓶颈，让灵巧手等高精度机器人部件的研发成为可能，也让机器人能够适配更多精细操作场景。

　　As the core of linear actuators for robot joints, the breakthrough of these two types of guide screw schemes has thoroughly promoted the "revolution" of robot joints. Compared to traditional guide screws, reverse planetary ball screws and reverse ball screw plates have significantly improved accuracy, volume, and load capacity. Especially with the development of 040.5 specification ball screw plates, the technological bottleneck of miniaturized guide screws has been broken, making it possible to develop high-precision robot components such as dexterous hands, and enabling robots to adapt to more precise operation scenarios.

　　从行业应用来看，导轨丝杠方案的选择，核心是匹配机器人关节的使用需求。手脚关节优先选择反向式行星滚珠丝杠，兼顾负载与灵活；手腕、灵巧手等精细部位，优先选择小型化反向式滚珠丝板，追求精度与小巧。无论是工业机器人的重载关节，还是服务机器人的灵巧关节，导轨丝杠的适配性都直接决定机器人的性能上限，这也是为什么说导轨丝杠是机器人关节革命的核心支撑。

　　From the perspective of industry applications, the core of selecting a guide screw solution is to match the usage needs of robot joints. Prioritize the use of reverse planetary ball screws for hand and foot joints, balancing load and flexibility; For delicate parts such as wrists and dexterous hands, priority is given to small-sized reverse ball screw plates, pursuing precision and compactness. Whether it is the heavy-duty joints of industrial robots or the agile joints of service robots, the adaptability of guide screws directly determines the performance limit of robots, which is why guide screws are the core support of the robot joint revolution.

　　很多人在选择机器人线性执行器时，容易陷入“精度越高越好”的误区，其实不然，导轨丝杠方案的选择，关键是“适配”。不同机器人关节的运动需求、负载大小、空间限制各不相同，只有结合关节部位的实际需求，选择对应的导轨丝杠方案，才能让机器人关节发挥性能，既保证动作精准流畅，又延长设备使用寿命。

　　Many people tend to fall into the misconception of "higher accuracy is better" when choosing linear actuators for robots. In fact, the key to choosing a guide screw solution is "adaptation". The motion requirements, load sizes, and space limitations of different robot joints vary. Only by selecting the corresponding guide screw scheme based on the actual needs of the joint parts can the robot joints perform at their best, ensuring precise and smooth movements while extending the service life of the equipment.

　　总而言之，导轨丝杠作为机器人关节的核心传动部件，其方案的创新的直接推动了机器人关节的升级迭代。反向式行星滚珠丝杠适配手脚关节，反向式滚珠丝板适配精细部位，两类方案相辅相成，解锁了机器人灵巧运动的新可能。了解不同导轨丝杠方案的适配场景，才能精准选择线性执行器方案，为机器人关节赋能，让机器人在各类场景中发挥更大价值，真正实现机器人关节的技术突破与升级。

　　In summary, as the core transmission component of robot joints, the innovative design of the guide screw directly promotes the upgrading and iteration of robot joints. The reverse planetary ball screw is adapted to the joints of hands and feet, and the reverse ball screw plate is adapted to fine parts. The two schemes complement each other, unlocking new possibilities for the agile movement of robots. Only by understanding the adaptation scenarios of different guide screw schemes can we accurately select linear actuator schemes, empower robot joints, and enable robots to exert greater value in various scenarios, truly achieving technological breakthroughs and upgrades in robot joints.
