Description

Technical Field

[0001] This utility model relates to the field of flexible coupling technology, and in particular to a flexible coupling with sensing function. Background Technology

[0002] A flexible coupling is a device used to compensate for the relative misalignment of the shafts of two connected shafts. When the coupling is in operation, its operating status can be monitored and fed back through built-in sensors. Therefore, the sensing function has a significant advantage in the operation of flexible couplings. By monitoring the coupling through the sensors, key parameters such as real-time speed and torque can be obtained, thereby promptly identifying potential problems or faults and preventing sudden failures from impacting production.

[0003] However, under certain environments, such as the influence of magnetic fields, the performance of sensing elements may be affected, leading to inaccurate or malfunctioning monitoring data. Furthermore, most couplings are installed with detachable bolt connections, but under high-speed operation, the threaded connections of the bolts may loosen, which may cause unstable installation of the equipment and pose certain safety hazards.

[0005] Therefore, to solve the above-mentioned technical problems, this utility model provides the following technical solution: a flexible coupling with sensing function, which includes:

[0006] The main unit includes a bushing and a diaphragm. The bushing and the diaphragm are provided with mounting holes, and fastening bolts are provided in the mounting holes. A gasket is provided on the diaphragm.

[0012] In a preferred embodiment of the flexible coupling with sensing function described in this utility model, a conductive wire is installed on the spacer.

[0013] The beneficial effects of this utility model are:

[0014] During use, the sensor detects the operating status of the coupling and monitors it in real time.

[0027] Example 1

[0028] Reference Figure 1-5 This is the first embodiment of the present invention, which provides a flexible coupling with sensing function. This structure includes:

[0029] The main unit 100 includes a bushing 101 and a diaphragm 102. Mounting holes are provided on both the bushing 101 and the diaphragm 102, and fastening bolts 103 are installed in the mounting holes. A washer 104 is provided on the diaphragm 102. During use, the bushing 1011 is fitted onto the drive shaft and driven shaft and secured with mounting bolts 1012. The sensing unit 200 is then inserted between the two bushings 101, and the fastening bolts 103 are inserted into the mounting holes. The polygonal nut 1034 is tightened to secure the bushing 101, diaphragm 102, and intermediate shaft 201. The extension section 1032 is then bent to fit against the polygonal nut 1034, thus securing the unit. Bolt 1033 is tightened to fix extension section 1032 to the surface of polygonal nut 1034. Since the limiting piece 1031 is fixed on bushing 101, extension section 1032 can limit polygonal nut 1034 and prevent loosening of polygonal nut 1034, which would lead to unstable installation. When the drive shaft and driven shaft rotate, the diaphragm 102 will bend and deform due to the change in distance and angle between the shafts. This deformation can absorb the relative displacement between the two shafts, including axial displacement, angular displacement and radial displacement, thereby maintaining the synchronous movement of the two shafts. Shim 104, as a protective element, can prevent damage caused by overload, impact and other reasons.

[0030] The sensing unit 200 includes an intermediate shaft 201, a spacer 202 fixed on the intermediate shaft 201, a mounting box 203 fixed inside the spacer 202, and a sensor 204 installed inside the mounting box 203. During use, the sensor 204 senses the operating status of the coupling and monitors parameters such as speed and torque in real time. This data is transmitted to a display device so that operators can monitor and adjust in real time. When used in a magnetic field environment, the sensor 204 is connected to the grounding wire through the conduction wire 2021 to provide electromagnetic shielding, limiting the interference of the external magnetic field to the surface of the spacer 202, thereby protecting the internal sensor 204 from the influence of the magnetic field. The mounting box 203 provides further protection for the sensor 204.

[0031] Furthermore, a sleeve 1011 is fixed on the bushing 101. The sleeve 1011 has a threaded hole, and a mounting bolt 1012 is threaded into the threaded hole. By inserting the mounting bolt 1012 into the threaded hole and locking it, the sleeve 1011 and the device can be installed on the running axis.

[0032] Furthermore, a limiting piece 1031 is fitted on the fastening bolt 103. The limiting piece 1031 is fixed on the bushing 101. An extension section 1032 is provided on the limiting piece 1031. The extension section 1032 is bent so that it is attached to the polygonal nut 1034. Since the limiting piece 1031 is fixed on the bushing 101, it can limit the polygonal nut 1034.

[0033] Furthermore, a first limiting hole is provided on the extension section 1032, and a fixing bolt 1033 is threaded into the first limiting hole. By locking the fixing bolt 1033 in the first limiting hole and the second limiting hole, the extension section 1032 can be tightly attached to and fixed to the surface of the polygonal nut 1034.

[0034] Furthermore, the surface of the fastening bolt 103 is also threaded with a polygonal nut 1034, which has a second limiting hole. By locking the polygonal nut 1034 onto the fastening bolt 103, the bushing 101 and the intermediate shaft 201 can be installed and fixed.

[0035] Furthermore, a conductive line 2021 is installed on the spacer 202, which is connected to the grounding line to serve as electromagnetic shielding, limiting the interference of external magnetic fields to the surface of the spacer 202, thereby protecting the internal sensor 204 from the influence of magnetic fields.

[0036] During use, firstly, sleeve 1011 is fitted onto the drive shaft and driven shaft, and fixed with mounting bolt 1012. Then, the sensing unit 200 is inserted between the two sleeves 101, and fastening bolt 103 is inserted into the mounting hole. The polygonal nut 1034 is then tightened to install and fix the sleeve 101, diaphragm 102 and intermediate shaft 201. Next, the extension section 1032 is bent so that it is attached to the polygonal nut 1034. The extension section 1032 is then tightened with fixing bolt 1033 to fix the extension section 1032 to the surface of the polygonal nut 1034. Since the limiting piece 1031 is fixed on the sleeve 101, the extension section 1032 can limit the polygonal nut 1034, preventing the polygonal nut 1034 from becoming loose and causing unstable installation.

[0037] Then, when the driving shaft and the driven shaft rotate, the diaphragm 102 will bend and deform due to the change in distance and angle between the shafts. This deformation can absorb the relative displacement between the two shafts, including axial displacement, angular displacement and radial displacement, thereby maintaining the synchronous movement of the two shafts. The gasket 104, as a protective element, can prevent damage caused by overload, impact and other reasons.

[0038] Finally, the sensor 204 senses the operating status of the coupling and monitors parameters such as speed and torque in real time. This data is transmitted to the display device so that the operator can monitor and adjust it in real time. When used in a magnetic field environment, it is connected to the grounding wire through the conduction wire 2021 to play the role of electromagnetic shielding, limiting the interference of the external magnetic field to the surface of the spacer 202, thereby protecting the internal sensor 204 from the influence of the magnetic field. The mounting box 203 provides further protection for the sensor 204.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
