Technical Field
[0001] This utility model relates to the field of humanoid robot technology, specifically to a high-precision, high-rigidity, long-life humanoid robot bearing with wear resistance. Background Technology
[0002] A humanoid robot is a robot designed to mimic the structure and behavior of the human body. Its ultimate goal is to create a machine that can move, interact, and perform tasks freely in human environments, just like a human. During the operation of a humanoid robot, bearings are used in various parts of the robot to reduce friction and ensure the support and rotational movement of each component, thus guaranteeing its motion accuracy, flexibility, and load-bearing capacity.
[0003] During operation, bearings utilize multiple sets of balls to maintain a working pattern where one set of inner and outer rings is fixed while the other rotates, ensuring proper support and rotation of all components within the robot. However, existing bearings make it difficult to monitor the internal operating environment and conditions in real time, hindering timely troubleshooting and consequently reducing bearing safety and lifespan. Therefore, this paper proposes a high-precision, high-rigidity, long-life humanoid robot bearing with wear resistance to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide a wear-resistant, high-precision, high-rigidity, long-life humanoid robot bearing to solve the problem mentioned in the background art that existing bearings are inconvenient to monitor the internal working environment temperature and working conditions in real time during use, thus making it inconvenient to deal with bearing problems in a timely manner, thereby reducing the safety and service life of the bearing.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant, high-precision, high-rigidity, long-life humanoid robot bearing, including an outer ring, an inner ring on the inner side of the outer ring, and multiple sets of balls placed between the outer ring and the inner ring. A protective cover is placed on the outer ring, and multiple sets of heat dissipation fins are provided on the upper end face of the protective cover. The protective cover has a base at each end, and a vibration sensor is embedded in the base. Another set of bases has an acoustic emission sensor built in. The acoustic emission sensor has a wire, and the other end of the wire is connected to the acoustic emission detection system inside the humanoid robot. The outer ring has a groove on one side of its outer wall, and a temperature sensor is installed inside the groove. The outside of the temperature sensor is filled with adhesive in the groove of the outer ring, and a protective shell is welded to the outer ring on the outside of the groove.
[0006] Preferably, the protective cover and the outer ring form a locking and limiting structure.
[0007] Preferably, the acoustic emission sensor is electrically connected to the acoustic emission detection system via a wire.
[0008] Preferably, the temperature sensor is embedded in the outer ring via a groove, and the protective shell is connected to the outer ring.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: The protective cover of the wear-resistant, high-precision, high-rigidity, long-life humanoid robot bearing forms a locking and limiting structure with the outer ring. This protects the bearing's interior while effectively ensuring overall heat dissipation, thus preventing excessive internal temperature from affecting its service life. The acoustic emission sensor of this device forms an electrical connection structure with the acoustic emission detection system via wires. The vibration sensor and acoustic emission sensor installed on the protective shell can monitor the internal movement of the bearing, providing timely alerts and intervention when wear occurs. The temperature sensor of this device forms an embedded structure with the outer ring via a groove, and the protective shell forms a connection structure with the outer ring. The combination of adhesive and protective cover increases the safety of the temperature sensor installation process, allowing for real-time monitoring of the bearing's operating temperature while effectively ensuring the sensor's service life.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0013] Please see Figure 1-4 This utility model provides a technical solution: a high-precision, high-rigidity, long-life humanoid robot bearing with wear resistance, including an outer ring 1, an inner ring 3 on the inner side of the outer ring 1, and multiple sets of balls 2 placed between the outer ring 1 and the inner ring 3. A protective cover 4 is placed on the outer ring 1, and multiple sets of heat dissipation fins 5 are provided on the upper end face of the protective cover 4. It should be noted that the device selects high-purity bearing steel material according to the actual situation to ensure its surface hardness and wear resistance, and can further increase its hardness and wear resistance through coating treatment. The bearing can be filled with high-temperature resistant lubricating oil or have micro-dimples laser-engraved on the bearing raceway surface to act as a grease reservoir, thereby effectively reducing the probability of friction inside the bearing.
[0014] Furthermore, the protective cover 4 and the outer ring 1 form a locking and limiting structure, thereby protecting the internal environment of the bearing through the limiting installation of the protective shell 4. At the same time, the multiple sets of heat dissipation fins 5 on the protective shell 4 effectively ensure the overall heat dissipation effect of the bearing, thereby preventing its internal temperature from being too high and affecting its service life.
[0015] The protective cover 4 has a base at each end, and a vibration sensor 9 is embedded in the base. Another set of bases has an acoustic emission sensor 8 built in. The acoustic emission sensor 8 has a wire, and the other end of the wire is connected to the acoustic emission detection system inside the humanoid robot. It should be noted that the vibration sensor 9 in this device is wirelessly connected to the control system and display system, so that the staff can view the internal working condition of the bearing and the data of each group through the external system.
[0016] Furthermore, the acoustic emission sensor 8 forms an electrical connection structure with the acoustic emission detection system through wires, thereby facilitating real-time monitoring of the operating volume inside the bearing and viewing the internal vibration through the vibration sensor 9, thus enabling timely detection of wear and other issues occurring inside the bearing.
[0017] The outer ring 1 has a groove on one side of its outer wall, and a temperature sensor 6 is installed inside the groove. The outside of the temperature sensor 6 is filled with adhesive in the groove of the outer ring 1, and a protective shell 7 is welded to the outer ring 1 on the outer side of the groove. It should be noted that the temperature sensor 6 in this device is wirelessly connected to an external control system and display system, so as to facilitate the monitoring of the internal temperature of the bearing through the temperature sensor 6. In addition, each group of electrical components of the rotating rod of this device is equipped with heat dissipation, control system and other structures during the installation process, so as to ensure that the electrical components can work normally according to the predetermined program. This utility model is a high-precision, high-rigidity and long-life humanoid robot bearing with wear resistance. All components are standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In this device, all the above-mentioned electrical components refer to the power element, electrical components and the matching monitoring computer and power supply, which are connected by wires. The specific connection method should refer to the working principle above and complete the electrical connection between the electrical components in sequence. The detailed connection method is the technology known in the art.
[0018] Furthermore, the temperature sensor 6 forms an embedded structure with the outer ring 1 through the groove, and the protective shell 7 forms a connection structure with the outer ring 1. Thus, the embedded temperature sensor 6 is provided with secondary protection through the welded metal protective shell 7 and the filling adhesive. In this way, the temperature sensor 6 can be used to monitor the internal working temperature of the bearing in real time, while effectively ensuring the service life of the temperature sensor 6 itself.
[0019] Working Principle: Using high-precision, high-rigidity, and long-life humanoid robot bearings with wear resistance, the bearing assembly is first installed in the appropriate position according to the robot's working conditions. During bearing use, the protective cover 4 can be installed on one or both sides depending on the operating conditions. The protective cover 4 protects the bearing's interior while the heat dissipation fins 5 on its surface effectively ensure heat dissipation, thus preventing high temperatures caused by long-term operation from affecting the bearing's lifespan. During bearing use, a temperature sensor 6 monitors the temperature in real time, allowing the humanoid robot's internal control and display systems to view the bearing's internal temperature and maintain optimal bearing performance. When the temperature is high, the robot is promptly stopped. Temperature sensor 6 is double-protected during operation by the filling adhesive and the welded metal protective shell 7, effectively ensuring its lifespan. During the overall operation of the bearing, the vibration sensor 9 and acoustic emission sensor 8 on the protective cover 4 can monitor its internal workings in real time. This allows for timely alerts via sound and vibration data when wear occurs inside the bearing, enabling staff to promptly stop the robot and perform maintenance. This further ensures the safety of bearings in various positions within the humanoid robot during use. This is the process of using this wear-resistant, high-precision, high-rigidity, long-life humanoid robot bearing.
[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
