Description

Technical Field

[0001] This invention relates to the field of coupling technology, and more specifically, to a coupling with easily replaceable friction plates. Background Technology

[0002] Couplings are essential components in mechanical transmission systems used to connect two shafts (driving shaft and driven shaft) to transmit torque and motion. They are widely used in various industrial equipment, such as machine tools, fans, pumps, and compressors. Their basic functions are to compensate for relative displacement between the two shafts (such as radial, axial, and angular misalignment), absorb vibration, and ensure smooth transmission.

[0003] However, existing friction couplings generally suffer from a significant drawback: replacing the friction plates is extremely inconvenient. As wear parts, the friction plates gradually wear down after prolonged operation or frequent overloads. When the wear reaches its limit, they must be replaced; otherwise, the transmitted torque will decrease, and the overload protection function will be lost. Traditional structures typically integrate the friction plates into the core of the coupling. Replacement requires complete disassembly and removal of the entire coupling from the shaft. This process is not only time-consuming and labor-intensive, but also necessitates precise realignment of the driving and driven shafts after reinstallation. For large production lines or equipment with limited installation space, this translates to lengthy downtime and high maintenance costs.

[0004] Therefore, it is necessary to provide a coupling with easily replaceable friction plates to solve the above problems. Utility Model Content

[0005] Based on the aforementioned problems in the prior art, the purpose of this application is to provide a coupling with convenient friction plate replacement, thereby facilitating friction plate replacement and improving work efficiency.

[0006] The technical solution adopted by this application to solve its technical problem is: a coupling with convenient friction plate replacement, including a first rotating shaft, a second rotating shaft being sleeved at the front end of the first rotating shaft, a bushing covering the upper end of the first rotating shaft and the second rotating shaft, a connecting piece being snapped into the upper end of the bushing, and a flange being fixedly installed on the inner side of the first rotating shaft and the second rotating shaft.

[0007] Furthermore, a first friction plate and a second friction plate are placed on the rear side of the flange sleeve, and a gasket is snapped into the rear end of the first friction plate and the second friction plate.

[0008] Furthermore, the upper ends of the first friction plate and the second friction plate are provided with threaded holes, and the front end of the threaded holes is threaded with an adjusting nut.

[0009] Furthermore, the front end of the adjusting nut is threaded with a fixing washer, and the inner sides of the first friction plate and the second friction plate are provided with snap-fit ​​grooves, which are adapted to the fixing washer.

[0010] The beneficial effects of this utility model are: as the friction plate wears down with use, the adjusting nut can be rotated and pushed forward through the threaded hole, pushing the fixed shim at the front end to press the friction plate, thereby compensating for the reduced clearance due to wear, restoring the required clamping force and friction torque, and ensuring the stable performance of the coupling.

[0012] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0013] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0014] In this invention, unless otherwise stated, the orientations used, such as "up" and "down," generally refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this invention.

[0015] like Figure 1-2As shown, this application provides a coupling with convenient friction plate replacement, including a first rotating shaft 1, a second rotating shaft 2 being sleeved at the front end of the first rotating shaft 1, a bushing 3 covering the upper ends of the first rotating shaft 1 and the second rotating shaft 2, a connecting piece 5 being snapped onto the upper end of the bushing 3, and a flange sleeve 12 being fixedly installed on the inner side of the first rotating shaft 1 and the second rotating shaft 2.

[0016] A first friction plate 4 and a second friction plate 7 are placed on the rear side of the flange sleeve 12, and a gasket 6 is snapped onto the rear end of the first friction plate 4 and the second friction plate 7.

[0017] The upper ends of the first friction plate 4 and the second friction plate 7 are provided with threaded holes 11, and the front end of the threaded holes 11 is threaded with adjusting nuts 8.

[0018] The front end of the adjusting nut 8 is threaded with a fixing washer 10. The inner sides of the first friction plate 4 and the second friction plate 7 are provided with a snap-fit ​​groove 9, which is adapted to the fixing washer 10.

[0019] Specifically, the starting power of the device is input from the first rotating shaft 1 or the second rotating shaft 2. The initial connection and torque transmission are achieved through the ferrule structure at the front end of the two shafts. The bushing 3 covering the upper end of the first rotating shaft 1 and the second rotating shaft 2 plays the main role in connection and torque transmission. The connecting piece 5 at the upper end ensures the synchronous rotation and stability of the overall structure. The flange sleeve 12 on the inner side serves as a structural support, enhancing the rigidity of the entire coupling.

[0020] When the coupling is working, the first friction plate 4 and the second friction plate 7 generate a preset friction force between the rear side of the flange sleeve 12 and the gasket 6. This friction force absorbs and buffers the vibration and impact that may be generated between the main and driven shafts. When the load torque exceeds the set value, the friction plate will slip, thereby cutting off the power transmission and protecting the motor and equipment from damage.

[0021] As the friction plates wear down with use, the adjusting nut 8 can be rotated to push the fixed shim 10 at the front end to press the friction plates, thereby compensating for the reduced clearance due to wear, restoring the required clamping force and friction torque, and ensuring the stable performance of the coupling.

[0022] When the friction plates are worn to their limit and need to be replaced, there is no need to disassemble the entire coupling or the aligned main shaft. First, loosen and remove the adjusting nut 8, then remove the fixing shim 10. Next, remove the worn first friction plate 4 and second friction plate 7 directly from the back of the flange sleeve 12. Finally, put the new friction plates back in place, reinstall the fixing shim 10, and tighten the adjusting nut 8 to the specified torque. Workers can replace different fixing shims 10 with different specifications of friction plates, thereby improving the compatibility of the device. The entire replacement process is simple and quick, greatly saving maintenance time and labor costs.
