Description

Technical Field

[0001] This utility model belongs to the technical field of clutch couplings, and in particular relates to a granulator clutch coupling that can be quickly disassembled and assembled. Background Technology

[0002] During the operation of the granulator, the clutch coupling is a key transmission component, which is usually composed of a pneumatic clutch and a coupling, and must have both installation compensation and overload protection functions.

[0003] Currently, most traditional clutch couplings used in granulators on the market employ bolt assemblies for connection and fixation. When transmitting large torques, a large number of load-bearing bolts are required to ensure connection strength and transmission stability.

[0004] However, this structure has obvious drawbacks: when performing online inspections, maintenance, or component replacements, the disassembly and installation of a large number of bolts consumes too much time, leading to extended downtime of the granulator and increasing the company's downtime costs. At the same time, the bolt disassembly and assembly process is cumbersome and may cause problems such as stripped bolts or damage due to improper operation, further affecting the equipment maintenance efficiency and service life.

[0005] Therefore, it is necessary to provide a new, quick-disassembly and reassembly granulator clutch coupling to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a granulator clutch coupling that is suitable for the transmission system of a granulator, which can significantly shorten the online maintenance and component replacement time, reduce the downtime cost of enterprises, and has a reliable structure, convenient maintenance, strong adaptability and quick disassembly.

[0007] To solve the above-mentioned technical problems, the granulator clutch coupling that can be quickly disassembled and assembled provided by this utility model includes: a connecting gear sleeve, a pneumatic clutch assembly, a left claw disc of the coupling, an inner inclined locking clamp, a rubber elastomer, a right claw disc assembly of the coupling, a cover and a retaining spring. The coupling right jaw plate assembly includes a right jaw plate, a snap ring, a left support ring, a right support ring, an outer inclined locking clamp, and a bushing.

[0008] As a further embodiment of this utility model, the outer side of the connecting tooth sleeve is provided with a beveled flange and the inner side is provided with an internal spline; the outer side of the pneumatic clutch assembly is provided with an external spline; the outer side of the left claw disc of the coupling is provided with a beveled flange and the left side of the beveled flange is provided with an external spline.

[0009] As a further embodiment of this utility model, the inner inclined surface locking hoop has a double inclined surface on its inner side and a tightening bolt on its outer side, and the outer inclined surface locking hoop has an inclined surface on its inner side.

[0010] As a further embodiment of this utility model, a bushing is provided on the inner side of the right claw disk, a left support ring is provided on the left side, a retaining spring is provided on the left side of the left support ring, a right support ring is provided on the right side of the right claw disk, and an outer inclined locking clamp is provided on the right side of the right support ring.

[0011] As a further embodiment of this utility model, the outer side of the bushing is provided with a retaining ring groove, the left side of the retaining ring groove is provided with a locking groove, the locking groove is provided with an inclined surface, the inner inclined surface of the outer inclined locking hoop is in close contact with the inclined surface of the outer locking groove of the bushing, and the left side of the outer inclined locking hoop is in close contact with the left side of the right support ring.

[0012] As a further embodiment of this utility model, the rubber elastomer is radially installed between the left and right jaw discs of the coupling, the cover is installed on the outside of the rubber elastomer and the right jaw disc, and a retaining spring is provided on the left side of the cover for secondary positioning.

[0013] As a further embodiment of this utility model, the inner spline of the connecting gear sleeve is engaged with the outer splines of the left and right claw discs of the coupling, and the double bevels of the inner bevel locking clamp are respectively attached to and locked in position with the bevel flange of the connecting gear sleeve and the bevel flange of the left claw disc of the coupling.

[0014] Compared with related technologies, the quick-disassembly and assembly granulator clutch coupling provided by this utility model has the following advantages: 1. This utility model replaces a large number of traditional fastening bearing bolts by setting a spline torque transmission structure (connecting the inner spline of the gear sleeve with the outer spline of the left and right claw discs of the coupling, and the right claw disc with the bushing). With the inclined locking method of the inner and outer inclined locking hoops, as well as the positioning function of the snap rings one and two, the disassembly and assembly process is greatly simplified. During online disassembly and assembly, there is no need to remove a large number of bolts. When inspecting and replacing parts offline (such as the pneumatic clutch assembly, the left and right claw discs of the coupling), only the corresponding locking hoop or snap ring needs to be loosened or removed. This significantly shortens the disassembly and assembly cycle and reduces the downtime cost of the granulator. 2. This utility model has a simple and reliable structure. The components are connected by inclined plane fit, spline engagement and snap ring positioning, which has high connection stability and is not prone to problems such as bolt stripping and loosening in traditional bolt connections. At the same time, the rubber elastomer can not only absorb vibration and ensure smooth transmission, but also provide a large installation compensation amount, which can effectively compensate for coaxiality errors during installation and improve the flexibility and adaptability of equipment installation. 3. This utility model can effectively protect key internal components (such as rubber elastomers and right claw discs) through the cover, preventing external dust and impurities from entering the interior and affecting the performance and service life of the components, thus extending the overall service life of the coupling and reducing the frequency and cost of equipment maintenance.

[0020] The inner inclined surface locking hoop 4 has a double inclined surface on its inner side and a tightening bolt on its outer side. The outer inclined surface locking hoop 6-5 has an inclined surface on its inner side.

[0021] The right claw disk 6-1 has a bushing 6-6 on its inner side and a left support ring 6-3 on its left side. The left support ring 6-3 has a retaining spring 6-2 on its left side. The right claw disk 6-1 has a right support ring 6-4 on its right side and an outer inclined locking band 6-5 on its right side.

[0022] The bushing 6-6 has a retaining ring groove on its outer side, and a locking groove on the left side of the retaining ring groove. The locking groove has an inclined surface.

[0025] The working principle of the quick-disassembly granulator clutch coupling provided by this utility model is as follows: This utility model allows for quick assembly before use: Step 1: Install the pneumatic component 2-1 of the pneumatic clutch assembly 2 onto the output shaft 9 of the granulator, ensuring that the pneumatic clutch assembly 2 is firmly connected to the output shaft 9 to guarantee the stability of subsequent power transmission; Step 2: Fix the bushing 6-6 onto the input shaft 10 of the granulator, ensuring that the bushing 6-6 rotates synchronously with the input shaft 10; then, sequentially put the outer inclined locking clamp 6-5, the right support ring 6-4, the cover 7, the right claw disc 6-1, and the left support ring 6-3 onto the bushing 6-6, without locking them for the time being; finally, install the snap ring 6-2 into the snap ring groove on the left side of the bushing 6-6 to initially limit the left support ring 6-3 and prevent it from falling off the left side of the bushing 6-6. Step 3: In offline mode, install the left claw disc 3 of the coupling on the right end of the clutch assembly of the pneumatic clutch assembly 2, ensuring that the two are connected and close together; then, put the connecting gear sleeve 1 on the external spline of the pneumatic clutch assembly 2 and the external spline of the left claw disc 3 of the coupling, so that the internal spline of the connecting gear sleeve 1 is fully engaged with the external splines of both, ensuring that the torque can be effectively transmitted; then, put the inner inclined locking clamp 4 on the inclined flange of the connecting gear sleeve 1 and the inclined flange of the left claw disc 3 of the coupling, and tighten the tightening bolts on the outside of the inner inclined locking clamp 4, so that the double inclined surfaces of the inner inclined locking clamp 4 are tightly engaged with the inclined flanges of the connecting gear sleeve 1 and the left claw disc 3 of the coupling, respectively, to achieve quick locking and positioning of the two; after completing the above offline assembly, hoist the assembled whole to the granulator installation position, assemble it with the pneumatic component 2-1 that has been installed on the output shaft 9, and tighten it with a few connecting bolts 2-3 to ensure that the overall structure is stably connected to the output shaft 9; Step 4: Connect the left side of the inner hole of the right claw disc 6-1 of the coupling to the left support ring 6-3, and the right side to the right support ring 6-4, and quickly lock and fix it to the bushing 6-6 with the outer inclined locking clamp 6-5; Step 5: Install the rubber elastomer 5 radially between the claws of the left claw plate 3 and the right claw plate 6-1 of the coupling, ensuring that the rubber elastomer 5 is fully fitted with the claws of the left and right claw plates, so as to effectively transmit torque and absorb vibration; finally, move the cover 7 to the left so that it is completely fitted on the outside of the rubber elastomer 5 and the right claw plate 6-1, and install the snap ring 8 on the outside of the right claw plate 6-1 to axially position the cover 7 and prevent the cover 7 from axially moving during equipment operation. This completes the assembly of the entire coupling.

[0026] The quick disassembly of this utility model: Step 1: When it is necessary to repair or replace some parts of the easily damaged clutch assembly, such as the pneumatic clutch assembly 2, first loosen the locking part of the outer inclined locking ring 6-5 to separate the outer inclined locking ring 6-5 from the inclined locking groove of the bushing 6-6; then remove the snap ring 8, move the cover 7 to the right to expose the rubber elastomer 5; then remove the rubber elastomer 5, move the right claw plate 6-1 to the right and back to make enough space, and the pneumatic clutch assembly 2 and the coupling left claw plate 3 and connecting gear sleeve 1 connected to it can be directly lifted radially for repair or replacement without disassembling the input shaft 10, output shaft 9 and other large components; Step 2: When it is necessary to replace the right claw disc 6-1, simply remove the snap ring 6-2 and loosen the outer inclined locking band 6-5. Then, the left support ring 6-2, right claw disc 6-1, and right support ring 6-4 can be removed from the bushing 6-6. After replacing the new right claw disc 6-1, install it in reverse according to the above assembly steps. Step 3: When it is necessary to remove the left jaw disc 3 of the coupling, simply remove a few connecting bolts 2-3 connected to the pneumatic clutch assembly 2, loosen the tightening bolts of the inner inclined locking clamp 4, so that the inner inclined locking clamp 4 is separated from the inclined flange of the connecting gear sleeve 1 and the left jaw disc 3 of the coupling, and then remove the connecting gear sleeve 1 from the outer spline of the left jaw disc 3 of the coupling and the pneumatic clutch assembly 2. The left jaw disc 3 of the coupling can then be removed from the clutch assembly of the pneumatic clutch assembly 2. The operation is convenient and quick, greatly reducing downtime maintenance time.
