DETAILED DESCRIPTION

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] Reference Figure 1-Figure 2 A reducer state monitoring device provided by an embodiment of the utility model includes a shell body 500, a wireless controller 200, and an input shaft temperature vibration sensor 110, a shaft bottom temperature vibration sensor 120, a shaft middle temperature vibration sensor 130 and a planetary gear temperature vibration sensor 140 installed on the shell body 500.

[0028] The input shaft temperature vibration sensor 110 is installed at a position on the housing body 500 corresponding to the reducer input shaft, and is used to collect vibration information and temperature information of the reducer input shaft bearing;

[0029] The shaft bottom temperature vibration sensor 120 is installed on the housing body 500 at a position corresponding to the shaft bottom of the reducer intermediate shaft 503, and is used to collect vibration information and temperature information of the shaft bottom bearing of the reducer;

[0030] The shaft middle temperature vibration sensor 130 is installed on the housing body 500 at a position corresponding to the shaft middle of the reducer intermediate shaft 503, and is used to collect vibration information and temperature information of the shaft middle bearing of the reducer;

[0031] The planetary gear temperature vibration sensor 140 is installed on the housing body 500 at a position corresponding to the planetary gear, and is used to collect vibration information and temperature information of the planetary gear of the reducer;

[0032] The wireless controller 200 is wirelessly connected to the input shaft temperature vibration sensor 110, the shaft bottom temperature vibration sensor 120, the shaft middle temperature vibration sensor 130 and the planetary gear temperature vibration sensor 140, respectively, and is used to receive the vibration information and temperature information sent by the input shaft temperature vibration sensor 110, the vibration information and temperature information sent by the shaft bottom temperature vibration sensor 120, the vibration information and temperature information sent by the shaft middle temperature vibration sensor 130, and the vibration information and temperature information sent by the planetary gear temperature vibration sensor 140, respectively.

[0033] Specifically, the temperature vibration sensor, also called the temperature vibration sensor, can not only monitor the vibration speed, movement direction and other factors related to mechanical vibration of the rotating mechanical equipment, but also measure the temperature conditions of the mechanical equipment in real time during operation. This embodiment mainly uses four temperature vibration sensors, namely the input shaft temperature vibration sensor 110, the shaft bottom temperature vibration sensor 120, the shaft middle temperature vibration sensor 130 and the planetary gear temperature vibration sensor 140, to detect the temperature information and vibration information of the input shaft, the shaft bottom, the shaft middle and the planetary gear respectively. The installation positions of the four temperature vibration sensors are as follows: Figure 1 Among them, the four temperature-vibration sensors all adopt the temperature-vibration integrated sensor model BPEG-100Ex / T.

[0034] Temperature plays an important role in reducer fault detection. When a reducer fails, it usually causes an abnormal temperature rise, and these temperature changes contain rich fault information. The temperature sensor can collect temperature data during the operation of the reducer in real time. By analyzing and processing this data, the type and degree of the reducer fault can be effectively detected.

[0035] First, by installing temperature sensors in key parts of the reducer, such as bearings, gearboxes, etc., the temperature changes of the reducer can be monitored in real time. When the reducer is operating normally, its temperature should remain stable within a certain range. When the reducer fails, friction, wear and other reasons will cause local temperature rise. The temperature sensor in the temperature vibration sensor can capture these temperature changes and transmit the temperature data to the analysis system. By real-time monitoring and recording of temperature data, when the temperature data rises abnormally, that is, exceeds the temperature range during normal operation, it indicates that the reducer may be faulty.

[0036] This embodiment also provides a hardware foundation for subsequent temperature data analysis by detecting temperature information. Fault diagnosis can be performed later by extracting temperature change information, such as temperature rise rate, temperature peak value, etc., because these characteristic information reflects the type and degree of reducer fault. For example, when the reducer has bearing damage, gear wear and other faults, the temperature rise rate will increase and the temperature peak will increase. The temperature data is detected by the temperature vibration sensor, which lays the hardware foundation for the subsequent determination of the specific fault type and degree.

[0037] Furthermore, when local damage occurs on the surface of a component of the reducer bearing, it will collide with other components during load operation, generating impact pulse force. Since the frequency band of the impact pulse force is very wide, it must include the natural frequencies of bearing components, sensors, etc., and arouse the high-frequency natural vibration of the vibration sensor in the temperature vibration sensor. In this embodiment, the vibration sensor in the temperature vibration sensor detects the vibration information of different positions of the reducer. In specific implementation, according to actual conditions, a certain high-frequency natural vibration can be selected as the research object, and the vibration information can be pre-processed by the wireless controller 200, such as bandpass filtering, to separate the natural vibration.

[0038] This embodiment uses a temperature and vibration sensor to detect temperature information and vibration information at different positions of the reducer, which has the advantages of real-time, accuracy and reliability. It can monitor the temperature and vibration changes of the reducer in real time during operation, providing strong support for subsequent fault diagnosis and maintenance.

[0039] It should be noted that the shaft bottom and shaft middle in this embodiment refer to the bottom and middle of the intermediate shaft of the reducer. Figure 1 As shown, the three shafts of the reducer are input shaft 501, output shaft 502 and intermediate shaft 503. Input shaft 501 is the shaft that inputs electromechanical energy to the reducer, and output shaft 502 is the main shaft responsible for outputting the power inside the reducer to the machine equipment. Intermediate shaft 503, also known as transition shaft, is the intermediate shaft connecting input shaft 501 and output shaft 502 in the reducer; it transmits energy, not only matching the power of input shaft 501 and output shaft 502, but also transmitting torque, balancing the movement of the shaft during the transmission process of the reducer; it can also form a multi-stage combined reducer through the combination of multiple intermediate shafts.

[0040] Figure 1The reducer in the figure is a SXJ type vertical bevel gear-planetary gear reducer manufactured by Beijing Electric Power Equipment General Factory Co., Ltd. The reducer mainly includes a first-stage spiral bevel gear and a first-stage planetary gear, and the two-stage gear transmission is connected together through a gear coupling 506. A large plane thrust bearing is installed at the output end, and the input end is driven by an electric motor. The motor drives the small spiral bevel gear 504 to mesh with the large spiral bevel gear 505, and then drives the sun gear 510 in the planetary gear system through the gear coupling 506 on the mounting shaft (intermediate shaft 503) of the large spiral bevel gear 505. The sun gear 510 meshes with the three planetary gears 507 installed in the planet carrier 509, so that the planetary gears 507 are forced to mesh with the internal gear 508 installed on the upper part of the housing body 500, and the diverted power is synthesized into the total power through the planet carrier 509 and then vertically output to the output shaft 502. The intermediate shaft 503 of this embodiment refers to the shaft on which the large spiral bevel gear 505 is installed and the shaft on which the gear coupling 506 and the sun gear 510 are installed. The two shafts are regarded as a whole as the intermediate shaft 503. The bottom of the intermediate shaft 503 refers to the position corresponding to the bearing below the large spiral bevel gear 505 in the spiral bevel gear transmission, and the bearing at this position is subjected to temperature detection and vibration detection; the middle of the intermediate shaft 503 refers to the position corresponding to the bearing above the large spiral bevel gear 505. It should be further explained that, as Figure 1 As shown, the intermediate shaft 503 is perpendicular to the input shaft 501, the small spiral bevel gear 504 is installed at the end (right end) of the input shaft 501 inside the housing, and the large spiral bevel gear 505 has a larger diameter than the small spiral bevel gear 504 and is installed at the lower part of the intermediate shaft 503 and meshes with the small spiral bevel gear 504 on the left.

[0041] Preferably, the input shaft temperature vibration sensor 110, the shaft bottom temperature vibration sensor 120, the shaft middle temperature vibration sensor 130 and the planetary gear temperature vibration sensor 140 are respectively wirelessly connected to the wireless controller 200. The model of the wireless controller 200 is BPEG-100T, and the cloud server 300 is connected to the wireless controller 200 via a 4G network or a 5G network.

[0042] The wireless controller 200 may also include a preprocessing module for preprocessing each signal, and these preprocessing modules may amplify, rectify, filter, etc. the signals output by the sensor. The filtering here is set separately according to different situations of the processed information. As mentioned above, bandpass filtering may be performed on vibration information.

[0043] Further, refer to Figure 3The position on the shell body 500 corresponding to the reducer input shaft, the position corresponding to the bottom of the reducer intermediate shaft 503, the position corresponding to the middle of the reducer intermediate shaft 503 and the position corresponding to the planetary gear are all horizontal mounting surfaces 520, and mounting seats 530 are respectively provided on the horizontal mounting surfaces 520. The lower surface of the mounting seat 530 is in contact with the horizontal mounting surface 520, and the upper surface of the mounting seat 530 is provided with mounting studs 531 for mounting sensors. The input shaft temperature vibration sensor 110, the shaft bottom temperature vibration sensor 120, the shaft middle temperature vibration sensor 130 and the planetary gear temperature vibration sensor 140 are respectively connected to the mounting studs 531 on the mounting seat 530 at the corresponding positions of the shell body. Figure 3 The planetary gear temperature vibration sensor 140 is taken as an example for description.

[0044] The horizontal mounting surface 520 can fit more closely with the bottom surface of the temperature vibration sensor. When the internal bearing or gear fails, the vibration and temperature rise caused are transmitted to the outer shell body 500. The temperature vibration sensor can detect these vibrations and temperatures more accurately and efficiently, thereby ensuring the effectiveness of the temperature vibration sensor detection.

[0045] The mounting base 530 can also be a magnetic base with a mounting stud 531. One end of the mounting stud 531 is used to connect the temperature vibration sensor. In order to obtain accurate data, the temperature vibration sensor should be installed in a preset position. When installing the temperature vibration sensor, attention should be paid to the directions of the x-axis, y-axis, and z-axis, and the vertical position should be better than the horizontal position and better than the axial position.

[0046] In specific implementation, the horizontal mounting surface 520 can be set as a horizontal, flat plane at the corresponding position when manufacturing the shell. In order to improve the accuracy of the sensor, the horizontal mounting surface 520 can also be set in a groove at the corresponding position of the shell. The wall thickness of the groove is set slightly thinner, and the size of the groove is adapted to the size of the bottom of the sensor so as to more sensitively detect vibration information.

[0047] In a possible implementation manner, a horizontal and flat horizontal mounting surface 520 can also be polished at a corresponding position of the outer shell, the installation position of the temperature vibration sensor is determined on the unit bearing, and the paint, rust and other coverings on the horizontal mounting surface 520 are removed. The diameter of the horizontal mounting surface 520 is larger than the bottom area of ​​the magnetic base of the temperature vibration sensor, ensuring that the bottom surface of the mounting base 530 (magnetic base) and the surface of the horizontal mounting surface 520 can be fully in contact; a bolt fastener is dripped into the thread of the temperature vibration sensor, and the mounting stud 531 and the temperature vibration sensor are connected and screwed onto the mounting base 530 (magnetic base) so that the temperature vibration sensor and the magnetic base are in contact without looseness; a metal repair agent configured in proportion is applied to the horizontal mounting surface 520, and then the temperature vibration sensor equipped with the magnetic base is fixed on the metal repair agent; after the metal repair agent is condensed, it is ensured that the temperature vibration sensor does not shake; to prevent the contact surface from rusting, anti-corrosion paint is applied to the exposed part of the outer edge of the horizontal mounting surface 520.

[0048] In a possible implementation, Figure 2 As shown, the wireless controller 200 preprocesses the information sent by the temperature vibration sensor to obtain preprocessed information, and sends the preprocessed information to the cloud server 300; the cloud server 300 is connected to the wireless controller 200, and obtains fault information based on the preprocessed information sent by the wireless controller 200; the terminal is then connected to the cloud server 300 to display the fault information.

[0049] Preferably, if Figure 1 As shown (in Figure 1 In the connection of each module, the dotted line represents a wireless connection, and the solid line represents a wired connection). The system of this embodiment also includes a sound sensor 160 connected to the wireless controller 200; the sound sensor 160 is installed at a position corresponding to the planetary gear on the shell body 500, and is used to detect the sound information of the reducer and send the sound information to the wireless controller 200.

[0050] In the speed reducer fault detection, the sound sensor 160 is installed next to the planetary gear temperature vibration sensor 140 of the housing body 500. The sound sensor 160 installed on the speed reducer housing can collect the sound information of the entire speed reducer operation process. Through the sound information, the overall working state of the speed reducer and whether there is a fault can be detected.

[0051] The sound sensor 160 plays an important role in the detection of reducer faults. When a reducer fails, abnormal sounds are usually generated, and these sounds contain rich fault information. The sound sensor 160 can collect the sound signals during the operation of the reducer in real time, and by analyzing and processing these signals, the type and degree of the reducer fault can be effectively detected.

[0052] The sound sensor 160 converts the sound into an electrical signal, which is then uploaded to the wireless controller 200 via wireless communication to collect the sound. The frequency, amplitude, phase, etc. in the sound signal reflect the working state and fault condition of the reducer. For example, when the reducer has faults such as gear wear and bearing damage, specific frequency components and amplitude changes will occur, which can be accurately captured by the sound sensor 160.

[0053] The use of the sound sensor 160 for speed reducer fault detection has the advantages of real-time, accuracy and non-contact, etc. It can monitor the working state of the speed reducer in real time during its operation, detect faults in time and issue early warnings to avoid further deterioration of the faults.

[0054] Here, the wireless controller 200 is also used to preprocess the sound information and send the preprocessed sound information to the cloud server 300; similar to the above, the cloud server 300 is also used to obtain fault information based on the preprocessed sound information sent by the wireless controller 200, and the terminal is also used to display the fault information.

[0055] In this embodiment, the sound information of the reducer is detected by the sound sensor 160, the sound information is pre-processed by the wireless controller 200, the cloud server 300 obtains the fault information according to the pre-processed information, and the terminal displays the fault information; this embodiment provides strong hardware support for accurately judging the type and degree of the fault.

[0056] Furthermore, it also includes a lubricating oil temperature and pressure detection module 170 connected to the wireless controller 200, which is used to detect the temperature information and pressure information of the reducer lubricating oil and send the temperature information and pressure information of the reducer lubricating oil to the wireless controller 200.

[0057] The detection of reducer lubricating oil temperature and pressure plays a vital role in the condition monitoring of reducer. The following are their main functions:

[0058] The temperature and pressure of lubricating oil are one of the key indicators for evaluating lubrication effect. High temperature may cause the oil to be too thin, reducing the lubrication effect, while low temperature may cause the oil to be too viscous, affecting lubrication performance. The pressure of lubricating oil is directly related to the normal operation of the lubrication system; by monitoring the oil temperature, you can understand whether the lubricating oil is working within the appropriate temperature range.

[0059] Friction and wear monitoring: The temperature and pressure of the oil have a great impact on the friction and wear of the internal parts of the reducer. By monitoring the oil temperature and pressure, excessive friction, insufficient lubrication or oil quality problems can be discovered in advance, thereby preventing excessive wear and damage to parts;

[0060] Evaluation of cooling effect: Lubricating oil is not only used for lubrication, but also for cooling the moving parts inside the reducer. By monitoring the oil temperature, the cooling effect of the lubricating oil can be evaluated. Excessive oil temperature may indicate a problem with the cooling system, which requires maintenance to prevent equipment failure due to overheating;

[0061] Leak detection, lubricating oil pressure detection can be used to monitor whether there is a leakage problem in the lubrication system. Abnormal pressure drop may be caused by a leak. Leaks should be found and repaired in time to ensure the normal operation of the lubrication system.

[0062] Predictive maintenance: By regularly monitoring the temperature and pressure of lubricating oil, you can establish a trend chart of the operation of the lubrication system. These trend charts can provide information such as equipment life prediction and maintenance plan formulation, thereby achieving predictive maintenance, reducing the occurrence of sudden failures, and improving equipment reliability and availability;

[0063] Energy saving and consumption reduction, normal lubricating oil temperature and pressure help maintain the efficient operation of the lubrication system. Through reasonable lubricating oil temperature and pressure control, energy consumption can be reduced and the working efficiency of the reducer can be improved. Reducer lubricating oil temperature and pressure detection is one of the key factors to achieve reducer status monitoring, improve equipment reliability and reduce maintenance costs. Through timely monitoring and analysis, comprehensive management of the lubrication system can be achieved to ensure the normal operation and long-term stability of the reducer.

[0064] In this embodiment, the lubricating oil temperature and pressure detection module 170 includes a reducer lubrication system controller and a wireless converter;

[0065] The reducer lubrication system controller 172 is used to obtain the temperature information and pressure information of the reducer lubricating oil, and send the temperature information and pressure information of the reducer lubricating oil to the wireless converter 171;

[0066] The wireless converter 171 is used to send the temperature information and pressure information of the reducer lubricating oil to the wireless controller 200 .

[0067] Specifically, the lubricating oil temperature and pressure data are collected by the reducer lubrication system controller 172, which can be a PLC (programmable logic controller). The reducer lubrication system controller transmits the lubricating oil temperature and pressure data to the wireless converter 171 via modbusRTU (a communication protocol based on a serial link), and the wireless converter 171 then uploads it to the aforementioned wireless controller 200 via a wireless network.

[0068] The wireless controller 200 preprocesses the temperature information and pressure information of the reducer lubricating oil, and sends the preprocessed temperature information and pressure information of the reducer lubricating oil to the cloud server 300. As mentioned above, the cloud server 300 is also used to obtain fault information according to the preprocessed temperature information and pressure information sent by the wireless controller 200, and the terminal is also used to display the fault information.

[0069] Furthermore, it also includes a reducer control system 150 connected to the wireless controller 200, and the reducer control system 150 is used to obtain the current information and the speed information of the reducer, and send the current information and the speed information to the wireless controller 200;

[0070] The wireless controller 200 is also used to pre-process the current information and the rotation speed information, and send the pre-processed current information and rotation speed information to the cloud server 300 .

[0071] In specific implementation, the wireless controller 200 is powered by 220V, and is provided with an Ethernet interface to facilitate reading the current information and speed information sent by the reducer control system 150, and a wireless antenna interface is provided, which can be directly fixed to the wall with expansion bolts or fixed to the mounting bracket on the wall with screws, so as to facilitate reading the temperature information, vibration information, lubricating oil temperature information, lubricating oil pressure information and sound information sent by four temperature and vibration sensors, wireless converter 171, and sound sensor 160, and a 4G or 5G wireless interface is also provided to communicate with the cloud server 300. There are 4 M6 threaded holes on the back of the wireless controller 200, which can be directly fixed to the wall with expansion bolts or fixed to the mounting bracket on the wall with screws.

[0072] like Figure 2 As shown, this embodiment includes multiple terminals, and the terminal can be one or more of a mobile phone, a desktop computer, a laptop computer, and a tablet computer. Figure 3 A possible implementation is given, where the terminal includes a desktop computer 411, a mobile phone 1 421, and a mobile phone 2 431. Mobile phone 1 may be installed with a WeChat applet capable of displaying fault information, and mobile phone 2 may be installed with a mobile phone APP capable of displaying fault information. The cloud server 300 performs expert diagnosis, and after obtaining the fault information, it is sent to the desktop computer via a wired network, and to mobile phones 1 and 2 via a wireless network.

[0073] A preferred implementation of this embodiment is to install a temperature vibration sensor, a sound sensor 160, a pre-reducer control system 150, and a lubricating oil temperature and pressure detection module 170 on the reducer to collect reducer vibration information, temperature information, sound information, lubricating oil temperature information, lubricating oil pressure information, reducer speed information and reducer current information, and transmit the aforementioned information to a nearby wireless controller 200 through industrial wireless communication for data information preprocessing and protocol conversion, and transmit it to the cloud server 300 of the reducer manufacturer through 4G or 5G to perform remote platform expert diagnosis, and send equipment alarm information to the terminal device of the reducer user in real time and issue equipment diagnosis reports regularly. At the same time, open PC and mobile terminal access rights to relevant managers of reducer users for platform access and monitoring.
