Description

Technical Field

[0001] This utility model belongs to the field of coupling technology, and in particular relates to a diaphragm coupling that facilitates component disassembly and replacement. Background Technology

[0002] Diaphragm couplings are high-performance flexible couplings that use one or more sets of thin, flexible metal diaphragms (called diaphragm discs) to transmit torque while compensating for various misalignments between the two connected shafts. They have significant advantages such as zero backlash, high rigidity, maintenance-free operation, resistance to harsh environments, good high-speed performance, and long service life. Although the cost is relatively high, they are an irreplaceable ideal choice for critical applications requiring precise transmission, high reliability, high speed, and maintenance-free operation, such as turbomachinery, energy, marine, and precision servo systems.

[0003] A search revealed a diaphragm disc coupling, disclosed in publication number CN219510037U, with an application date of March 1, 2023. The coupling includes an input shaft and an output shaft at both ends, and a middle component. An input diaphragm disc assembly and an output diaphragm disc assembly are fixedly connected to each other at their respective ends. A retaining sleeve is fixedly connected to the end faces of both the input and output diaphragm disc assemblies. The middle component connects between the retaining sleeves on both sides, and both ends of the middle component are equipped with limiting mechanisms and fixing mechanisms between them and the retaining sleeves. The assembly structure formed by the input shaft, output shaft, and middle component allows for disassembly. The middle component is connected to the retaining sleeves on both sides via two sets of connecting bolts to transmit torque. The connection structure is simple, easy to assemble and disassemble, and convenient for maintenance. Simultaneously, the limiting and fixing mechanisms improve the strength of the diaphragm disc connection and enhance torque transmission, effectively improving the axial load-bearing capacity of the diaphragm disc and increasing the torque of the drive shaft.

[0004] However, it still has the following drawbacks in practical use: Existing diaphragm couplings that facilitate component disassembly and replacement use bolts to connect the input shaft, output shaft, and intermediate components. However, this method is cumbersome, time-consuming, labor-intensive, and inefficient for workers, making it difficult to quickly disassemble and replace components. 2. Existing diaphragm couplings that facilitate component disassembly and replacement connect the input and output shafts via an intermediate component. However, this method cannot adjust the shaft length as needed, limiting its applicability. Therefore, we provide a diaphragm coupling that facilitates component disassembly and replacement to address the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a diaphragm disc coupling that facilitates component disassembly and replacement. By setting the installation components, four bolts can be synchronously and stably screwed into the corresponding nuts, improving disassembly and assembly efficiency, facilitating component disassembly and replacement, and the shaft length can be changed according to requirements by using the extension shaft, increasing the scope of application.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a diaphragm disc coupling that facilitates component disassembly and replacement. It includes an extension shaft and a connecting shaft inserted at both ends thereto. A second flange and a third flange are respectively fixed at both ends of the outer wall of the connecting shaft, and an installation component is provided at the outer end of the outer wall of the connecting shaft. The mounting components include a gear ring that rotates and is fitted onto the outer wall of the connecting shaft, and a gear disc that meshes around the outer wall of the gear ring.

[0007] The present invention is further configured such that a first flange is fixedly provided at both ends of the outer wall of the extension shaft, and a first insert is fixedly provided at the center of both sides of the extension shaft.

[0008] The present invention is further configured such that a first slot is provided at the center of one side wall of the connecting shaft, and a second plug is fixed at the center of the other side wall of the connecting shaft.

[0009] The present invention is further configured such that an output shaft is provided at the outer end of the connecting shaft, and a fourth flange is fixedly provided at one end of the outer wall of the output shaft.

[0010] The present invention is further configured such that a second slot is provided at the center of one side wall of the output shaft, and protective sleeves are provided on the outer sides of the third flange and the fourth flange.

[0011] The present invention is further configured such that the first plug-in is slidably inserted into the inside of the first slot, and the second plug-in is slidably inserted into the inside of the second slot.

[0012] The present invention is further configured such that the toothed disc is sleeved on the outer wall of the bolt, and the bolt is rotatably mounted in the bearing on the third flange.

[0013] The present invention is further configured such that one end of the bolt passes through the through hole on the fourth flange and the through hole on the sleeve in sequence and is connected to the nut, and the four nuts are respectively fixed on the outer wall of the ring plate.

[0014] This utility model has the following beneficial effects: This invention, through the installation component, utilizes a gear ring that meshes with four gear discs. Rotating the four bolts sequentially causes the remaining three bolts to rotate synchronously, ensuring the bolts are screwed into their corresponding nuts. This allows the four bolts to be stably screwed into their respective nuts, improving assembly and disassembly efficiency and facilitating component removal and replacement. It solves the problem that existing diaphragm couplings, which facilitate component removal and replacement, use bolts to connect the input shaft, output shaft, and intermediate components. However, this method is cumbersome, time-consuming, labor-intensive, inefficient, and inconvenient for quick component removal and replacement.

[0015] This invention, by setting an extension shaft and using bolts to install the extension shaft between two connecting shafts, allows the shaft length to be changed according to needs, thus increasing the scope of application. It solves the problem that existing diaphragm couplings, which facilitate component disassembly and replacement, connect the input and output shafts through an intermediate component, but this method cannot change the shaft length according to needs and has a limited scope of application.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1, please refer to Figures 1 to 3 This utility model is a diaphragm disc coupling that facilitates component disassembly and replacement. It includes an extension shaft 100 and a connecting shaft 200 inserted at both ends thereon. A second flange 201 and a third flange 202 are respectively fixed at both ends of the outer wall of the connecting shaft 200.

[0024] Specifically, both ends of the outer wall of the extension shaft 100 are fixed with a first flange 101, and the center of both side walls of the extension shaft 100 are fixed with a first insert 102; the center of one side wall of the connecting shaft 200 is provided with a first slot 203, and the center of the other side wall of the connecting shaft 200 is fixed with a second insert 204; the outer end of the connecting shaft 200 is provided with an output shaft 205, and one end of the outer wall of the output shaft 205 is fixed with a fourth flange 205a; the center of one side wall of the output shaft 205 is provided with a second slot 205b, and the outer sides of the third flange 202 and the fourth flange 205a are fitted with a protective sleeve 206; the first insert 102 is slidably inserted into the inside of the first slot 203, and the second insert 204 is slidably inserted into the inside of the second slot 205b.

[0025] Furthermore, by adding an extension shaft 100, the length of the shaft can be changed according to requirements. The first flange 101 on the extension shaft 100 is connected to the second flange 201 on the connecting shaft 200 by bolts 302. The first plug and the first slot 203 cooperate to realize the docking of the extension shaft 100 and the connecting shaft 200. The second plug and the second slot 205b cooperate to realize the docking of the connecting shaft 200 and the output shaft 205. Since the sheath 206 is sleeved on the outside of the third flange 202 and the fourth flange 205a, it can play a protective role.

[0026] The operation process of this embodiment is as follows: Since the extension shaft 100 is provided with a first flange 101 at both ends of its outer wall, and the connecting shaft 200 is provided with a second flange 201 and a third flange 202 at both ends of its outer wall, when the diaphragm coupling is assembled normally, it is only necessary to connect and install the second flanges 201 on the two adjacent connecting shafts 200 by bolts 302. If it is necessary to increase the shaft length, the extension shaft 100 is placed in the middle of the two adjacent connecting shafts 200, and the first flange 101 and the corresponding second flange 201 are connected and installed by bolts 302, so that the shaft length can be changed according to the requirements and the applicable range can be increased.

[0027] Example 2, please refer to Figure 3 and Figure 4 Based on Embodiment 1, unlike the first embodiment, an installation component 300 is provided. The installation component 300 includes a gear ring 301 rotatably sleeved on the outer wall of the connecting shaft 200, and a gear disc 303 meshing around the outer wall of the gear ring 301. This solves the problem that existing diaphragm couplings that facilitate component disassembly and replacement use bolts to connect the input shaft, output shaft and intermediate component, but this method is cumbersome, time-consuming and labor-intensive, with low work efficiency and is not convenient for quick disassembly and replacement of components.

[0028] Specifically, the gear plate 303 is sleeved on the outer wall of the bolt 302, and the bolt 302 is rotatably installed in the bearing on the third flange 202; one end of the bolt 302 passes through the through hole on the fourth flange 205a and the through hole on the sleeve 206 in sequence and is connected to the nut 305, and the four nuts 305 are respectively fixed on the outer wall of the ring plate 304.

[0029] Furthermore, four of each of the following are provided: gear disc 303, bolt 302, and nut 305. The rack on the outer wall of the gear ring 301 meshes with the rack on the outer wall of the gear disc 303, which serves as a transmission mechanism. The four nuts 305 are all provided on the ring plate 304 to achieve synchronous screwing of bolt 302 and nut 305, thereby improving stability. When screwing bolt 302, force needs to be applied to the four bolts 302 in sequence to avoid uneven force on the four bolts 302, which would affect the screwing efficiency. The bolt 302 is rotatably mounted in the bearing on the third flange 202.

[0030] The operation process of this embodiment is as follows: When it is necessary to disassemble and assemble the connecting shaft 200 and the output shaft 205, firstly, the through hole on the fourth flange 205a on the output shaft 205 is fitted onto the outside of the bolt 302. Then, the sheath 206 is inserted into the output shaft 205, and its through hole is inserted into the outer wall of the bolt 302. Next, the ring plate 304 is fitted onto the outer wall of the output shaft 205, and at the same time, the nut 305 is aligned with the corresponding end of the bolt 302. Then, force is applied to one of the bolts 302, and the bolt 302 is subjected to... The force of rotation will cause the gear disk 303 to rotate, and the gear disk 303 meshes with the gear ring 301. Therefore, the rotation of the gear disk 303 will cause the gear ring 301 to rotate synchronously, and also cause the remaining three gear disks 303 and bolts 302 to rotate synchronously. This allows the bolts 302 to be screwed into the corresponding nuts 305. When applying force to the bolts 302, force can be applied to all four bolts 302 in sequence, so that the four bolts 302 can be stably screwed into the corresponding nuts 305, improving the efficiency of disassembly and assembly, and facilitating the disassembly, assembly and replacement of components.
