Description

Technical Field

[0001] The utility model belongs to the technical field of couplings and relates to a coupling with a composite detection function. Background Art

[0002] Couplings play an extremely important role in the transmission system of modern industry, and the performance requirements for couplings have been raised to a new level. Performance such as vibration reduction, reliability, safety, long service life and noise reduction are all required to meet high-level standards. Moreover, in order to adapt to the trend of intelligent and digital industrial development, it is particularly important to give couplings self-detection capabilities. This self-detection capability can record the operating status of the coupling in real time, thereby providing a basis for analyzing the operating conditions of the motor input and load output ends, helping to determine the equipment pre-maintenance cycle. At the same time, its real-time transmitted data combined with the preset alarm limit can become an important part of the construction of intelligent systems and digital factories.

[0003] However, in the existing technical means, monitoring a certain stress state of the coupling is mainly achieved by adding corresponding measuring sensors in the transmission system. This solution does have certain advantages. It can measure a variety of different parameters to meet the monitoring needs of different aspects of the coupling.

[0004] However, this solution also exposes many disadvantages. First, from the perspective of cost, as the number of sensors in the coupling transmission system increases, the cost of use will inevitably increase. This is not only the purchase cost of the sensor itself, but also the cost increase caused by the additional requirements for the electrical signal processing part of the system due to the increase in the number of sensors, such as the need for more signal channels, signal processing equipment, and additional power supply. Secondly, there are many inconveniences in installation. On the one hand, it is necessary to select sensors with appropriate ranges and installation positions based on existing equipment, which is a complicated and time-consuming process; on the other hand, many transmission mechanisms (systems) may not have enough installation space to accommodate these sensors. If the measurement purpose is to be met, component replacement is required, which will undoubtedly lead to additional cost increases. Finally, from the perspective of safety and stability, the coupling is in a rotating state when it is working normally, and too many sensor cables will cause wiring difficulties. In a high-speed rotating system, there is also a risk that the cable will be caught in the rotating mechanism, which will cause downtime accidents and cause unstable signal transmission, affecting the normal operation of the entire transmission system.

[0005] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. Utility Model Content

Embodiment

[0039] See Figures 1 - 4As shown in the figure, a coupling with a composite detection function is installed between the motor shaft and the load device, and includes a base 1 integrated with a control box and an intermediate body 2. A stator disk 4 connected to the base is provided on the base 1; a rotor disk 5 is fixedly connected to the intermediate body 2 and can rotate with the intermediate body 2. The stator disk 4 and the rotor disk on the intermediate disk 2 are connected in a non-contact manner to transmit data by electromagnetic induction. Among them, the stator disk 4 and the rotor disk 5 are isolated and protected by a housing 3.

[0040] Particularly, a grating disk 51 is provided on the rotor disk 5, and a photosensitive device for sensing the grating disk 51 is provided on the stator disk 4. The combination of the grating disk 51 and the photosensitive device provides an accurate means for detection. Specifically, a specific number of grating holes are circumferentially provided on the grating disk 51. When the rotor disk 5 rotates, the grating disk 51 rotates together. After the photosensitive device (which can be a photoelectric sensor) emits a light signal, it collects the light reflected on the grating disk 51, and the number of holes in the grating disk 51 serves as the corresponding acquisition accuracy. The received light is converted into a pulse signal and transmitted to the processing unit in the control box (that is: the photosensitive device emits a light signal and passes through the reflection of the light not transmitted through the grating holes on the induction grating disk 51, and converts the received light into a pulse signal and transmits it to the processing unit). The processing unit can accurately calculate important parameters such as the rotational speed and rotation angle of the rotor disk 5 based on information such as the frequency of the pulse signal and the number of grating holes. This design realizes the accurate monitoring of the operating state of the coupling, which helps to achieve efficient and stable transmission between the motor and the load device.

[0041] In addition, strain gauges are provided on the intermediate body 2 in this embodiment. The installation steps of the strain gauges are as follows: First, clean the surface of the intermediate body 2 and then preheat it. Then, stick two groups of strain gauges to the surface of the intermediate body 2 and fix them with high-temperature resistant tape; then place the pasted sample in an environment of 190°C for 1.5 hours for glue curing; next, lead out connection wires from the strain gauges and form a Wheatstone bridge with a circuit board; then weld the lead-out wires, and perform zero-point compensation on the strain gauges through special equipment; finally, apply a protective glue on the surface and fix the leads.

[0042] During the operation of the coupling, when the intermediate body 2 is subjected to torque, it will deform. Since the strain gauges are pasted on the rotor disk 5 and at positions corresponding to the intermediate body 2, the torque deformation of the intermediate body 2 will change the resistance of the strain gauges. The strain gauges and the first induction coil on the rotor disk 5 form a loop through an amplifier circuit. The role of the amplifier circuit is crucial because the change in the resistance of the strain gauges is usually very small. Through the amplifier circuit, this small change in resistance can be converted into a detectable electrical signal and cause a change in current in the loop.

[0043] A second induction coil corresponding to the first induction coil is provided on the stator disk 4, and data is transmitted by electromagnetic induction. According to the principle of electromagnetic induction, when the current in the first induction coil on the rotor disk 5 changes due to the change in the strain gauge resistance, a changing magnetic field will be generated. The second induction coil on the stator disk 4 is in this changing magnetic field, and an induced electromotive force will be generated. The second induction coil is electrically connected to the processing unit in the control box, so as to transmit the received electrical signals related to the change in the strain gauge resistance to the processing unit. The processing unit can further analyze information such as the magnitude of the torque received by the intermediate body 2 based on these electrical signals, providing more accurate data support for the working state monitoring, fault warning, and equipment maintenance of the coupling.

[0044] Specifically, the intermediate body 2 has an "I" - shaped structure, and its two ends are flange plates 21 and 22. The flange plates 21 and 22 are respectively connected to the shaft sleeve 7 through the diaphragm 6. The intermediate body 2 is made of a rigid material, and this rigid material is 40CrNiMoA alloy steel, which has the characteristic of good wear resistance.

[0045] From the basic functions of the coupling, the intermediate body 2, as an important part connecting the motor shaft and the load equipment, needs to achieve functions such as power transmission, compensation for axial and radial displacement deviations, and buffering vibration. The wear resistance ensures the reliability of the intermediate body during long - term use and reduces the performance degradation caused by wear. Since the strain gauges are arranged at positions corresponding to the intermediate body, this torque deformation can be easily sensed by the strain gauges, and then the strain gauges will change in resistance. Through the subsequent induction coils and circuits, the relevant signals are transmitted to the processing unit in the control box to achieve precise detection of the force condition of the intermediate body, etc.

[0046] As Figure 3 shown, the processing unit is an integrated circuit board, which has a data processing module and power supply module, reset module, storage module, output module, acquisition module, etc. that are electrically connected to the data processing module. Among them:

[0047] The acquisition module receives signals from the photosensitive device and the second induction coil, etc., and preliminarily conditions these signals, such as operations like filtering and amplification, so that the signals meet the input requirements of the data processing module to ensure the accuracy of subsequent data processing.

[0048] The data processing module is the key part of the processing unit. It is responsible for processing various signals received from the photosensitive device (pulse signals generated through feedback and processing by the induction grating disk) and the second induction coil (electrical signals related to the change in the strain gauge resistance), etc. It uses pre - set algorithms to analyze and calculate these signals, so as to obtain various parameters regarding the working state of the coupling, such as rotational speed, rotation angle, torque magnitude, etc.

[0049] The power supply module provides the necessary electrical energy for the entire processing unit. It converts and stabilizes the externally input electrical energy to ensure a stable and appropriate voltage is provided for the data processing module, reset module, storage module, output module, acquisition module, etc., so as to ensure the normal operation of each module. Without a stable power supply, other modules will not be able to operate normally.

[0050] The reset module is used to restore the processing unit to its initial state under specific circumstances. For example, when the processing unit encounters a program error, abnormal operation, or receives an external reset instruction, the reset module can restore components such as registers and counters to their default values, enabling the processing unit to start normal operation again and ensuring the accuracy and stability of data processing.

[0051] The storage module is used to store various data during the operation of the processing unit. It includes pre-set parameters, such as the number of grating holes used to calculate the rotational speed, and data temporarily stored during operation, such as the pulse signal and electrical signal data collected, and the intermediate results processed by the data processing module. It provides a data caching function for the continuous processing and subsequent query of data.

[0052] The output module is mainly responsible for sending out the data on the working state of the coupling obtained after being processed by the processing unit. It transmits data to the backend device or host computer through wireless or wired transmission. The wireless transmission method facilitates the remote monitoring and centralized management of data, enabling operators to obtain the working state information of the coupling in real time from a location far away from the coupling, which is convenient for the effective control and maintenance of the entire system.

[0053] The debugging module plays a crucial role in the development, testing, and subsequent maintenance of the coupling. During the development stage, it allows engineers to adjust and optimize the data processing algorithms in the processing unit to accurately process the signals from the photosensitive device and induction coil. During the testing process, the debugging module can set different test parameters, simulate signal inputs under various working conditions, and check whether the output of the processing unit meets the expectations. During maintenance, technicians can use the debugging module to troubleshoot the processing unit and find possible problems.

[0054] The self-detection module is responsible for detecting the processing unit of the coupling itself. It periodically or as needed conducts self-checks on each component such as the data processing module, power supply module, and storage module. For example, it can detect whether the arithmetic function of the data processing module is normal, whether the voltage output of the power supply module is stable, and whether the data reading and writing of the storage module are error-free. Once any abnormal situation is detected, the self-detection module will promptly send an alarm message to the relevant system to take corresponding repair measures to ensure the normal operation of the coupling.

[0055] The processing unit also has an alarm circuit electrically connected to the data processing module. After the data processing module analyzes and processes the data received from various sensors (such as the rotational speed signal obtained through the photosensitive device of the induction grating disk, and the torque signal obtained from the change in the resistance of the induction strain gauge), if it is found that the data exceeds the normal working range, such as too high or too low rotational speed, abnormal torque, etc., an abnormal signal will be sent to the alarm circuit. After receiving the signal, the alarm circuit activates corresponding alarm actions according to the pre-set alarm rules. This may include emitting an audible and visual alarm signal to intuitively prompt the operator that there is an abnormal condition with the coupling. In some automated production environments, the alarm circuit can also be connected to the monitoring system of the entire production system to transmit the alarm information to the remote monitoring terminal, facilitating timely measures to be taken to avoid greater losses caused by coupling failures.

[0056] A data connector 12 electrically connected to the processing unit is provided on the base 1. It is the interface for the processing unit to interact with external devices. By connecting to the data line through the data connector 12, the processing unit can transmit the working state data of the coupling to other devices, and at the same time can receive instructions or configuration information sent by external devices.

[0057] A sealing plate 11 that seals one side of the control box is provided on the base 1, and the sealing plate 11 is locked to the base 1 by screws. This design effectively protects the processing unit inside the control box, preventing external impurities such as dust and water vapor from entering the control box and affecting the normal operation of the processing unit.

[0058] The processing unit is placed inside the control box, and this layout makes the structure of the entire coupling more compact. When the processing unit needs to be replaced and maintained, since the sealing plate 11 is locked by screws, only the sealing plate needs to be removed to process the processing unit. This design greatly reduces the difficulty of maintaining the processing unit, eliminating the need for complex disassembly operations on the entire coupling, saving maintenance time and costs, improving the maintainability of the equipment, and ensuring that the coupling can operate stably in the industrial environment for a long time.

[0059] In this embodiment, the rotor disk 5 is composed of an upper rotor disk and a lower rotor disk, and the upper rotor disk and the lower rotor disk are fastened to the intermediate body 2 by screws and cured with glue. This fastening method ensures the stability of the connection between the rotor disk 5 and the intermediate body 2. During the assembly process, the upper and lower rotor disks are accurately fixed to the intermediate body 2 by screws, enabling the rotor disk 5 to rotate stably with the intermediate body 2 and meeting the transmission requirements of the coupling.

[0060] The stator disk 4 is composed of an upper stator disk and a lower stator disk. The upper stator disk and the lower stator disk are fastened by screws, and the lower stator disk is fixed to the base 1 by screws. This structural design makes the assembly of the stator disk more convenient and the structure more stable.

[0061] In actual use, this coupling is an easily replaceable part, and this feature brings great convenience to the maintenance of the equipment. Among them, the stator disc 4 is used as a fitting. When maintenance or replacement is required, it only needs to be removed and reinstalled, without the need to be replaced together with the coupling. This design not only reduces the maintenance cost, but also reduces the time waste and the impact on the entire transmission system that may be caused by replacing the entire coupling. When problems occur with the stator disc, targeted treatment can be carried out quickly and efficiently to ensure the normal operation of the equipment.

[0062] The coupling of the present utility model is an innovative transmission connection device with many unique advantages.

[0063] First of all, integration has been achieved in the monitoring function. A grating disc is integrated on the rotor disc, and at the same time, a photosensitive device is set in the stator disc area. The two cooperate to achieve accurate monitoring of the rotational speed. A specific number of grating holes are arranged circumferentially on the grating disc. As the rotor disc rotates, the photosensitive device senses the reflected light on the grating disc and converts it into a pulse signal. After this pulse signal is transmitted to the processing unit, accurate rotational speed data can be obtained through processing. In addition, by setting strain gauges on the intermediate body, when the intermediate body is deformed by torque, the resistance of the strain gauges changes, and the resistance change of the strain gauges is sensed to measure the torque. This design that integrates the measurement of specific data such as torque and rotational speed greatly improves the functionality of the coupling.

[0064] In terms of structural design, this integrated measurement method has a high utilization rate of the installation space. Compared with the traditional method of using different devices to measure torque and rotational speed separately, this coupling of the present utility model does not need to set aside a large amount of space for each measuring device separately, which is more beneficial for the overall structural design and space planning. At the same time, the stator disc and the rotor disc, as important components, are designed as fittings that only need to be removed and reinstalled, without the need to be replaced together with the coupling. In this way, when problems occur with the stator disc or the rotor disc, they can be maintained or replaced separately, which is both convenient and can reduce costs.

[0065] In terms of data transmission, the adoption of wireless transmission is also a major highlight. Traditional wired transmission requires the laying of cables, which is not only cumbersome during installation, but also the cables may be affected by problems such as wear and pulling during use, affecting the stability of data transmission. The data transmission of this coupling adopts wireless transmission, no longer restricted by the use of cables, making the data transmission more flexible and stable, and also facilitating the data interaction between the coupling and the backend device or the host computer, and can better meet the development needs of modern industrial automation and intelligence.

[0066] To sum up, the coupling of the present utility model has significant advantages in terms of function integration, structural design, component maintenance, and data transmission, and can be widely applied to various industrial transmission fields.
