Description

Technical Field

[0001] This utility model specifically relates to a coupling with high assembly efficiency. Background Technology

[0002] In modern mechanical transmission systems, couplings are crucial components that connect two shafts or a shaft to a rotating part to achieve motion and power transmission and remain connected under normal circumstances. Their performance significantly impacts the overall system's operating efficiency and stability. With the rapid development of industrial production towards higher precision, higher speed, and higher automation, various industries have placed extremely stringent demands on the assembly efficiency of mechanical equipment, making coupling assembly efficiency one of the important indicators for evaluating its performance.

[0003] Traditional couplings come in many types. Rigid couplings, for example, are simple in structure and inexpensive, but require extremely high coaxiality between the two shafts during assembly. Even a slight deviation between the two shafts not only makes assembly extremely difficult but also generates significant additional stress during operation, severely impacting the equipment's lifespan. While flexible couplings can compensate for relative displacement between the two shafts and provide cushioning and vibration reduction to some extent, their complex structural design makes assembly cumbersome. With numerous parts, precise alignment and installation require considerable time and manpower.

[0004] Therefore, it is necessary to invent a coupling with high assembly efficiency to solve the above problems. Utility Model Content

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-4 To achieve the above objectives, the present invention provides the following technical solution: a coupling with high assembly efficiency, comprising a drive shaft connecting disc 1 and a driven shaft connecting disc 2, with a connecting component 3 installed between the two;

[0030] Specifically, both the drive shaft connecting plate 1 and the driven shaft connecting plate 2 are provided with connecting holes 4, and the driven shaft connecting plate 2 is provided with a fixing groove 41 at the connecting hole 4;

[0031] Specifically, the connecting assembly 3 includes a mounting ring 31, on which a plurality of connecting rods 32 are provided. The plurality of connecting rods 32 pass through the connecting holes 4 on the drive shaft connecting plate 1 and into the connecting holes 4 on the driven shaft connecting plate 2. A fastening nut 33 is provided in the fixing groove 41. The fastening nut 33 is located outside the connecting rod 32. Elastic buffer assemblies 5 are installed on both sides of the outer wall of the connecting rod 32. The elastic buffer assemblies 5 are placed between the mating surfaces of the drive shaft connecting plate 1 and the driven shaft connecting plate 2.

[0032] In this embodiment, before installation, it is necessary to check the integrity and good condition of each component. The focus is on checking whether the connecting holes 4 on the drive shaft connecting plate 1 and the driven shaft connecting plate 2 are smooth and burr-free, and whether the size of the fixing groove 41 at the connecting hole 4 on the driven shaft connecting plate 2 matches the fastening nut 33. It is also necessary to check whether the grooves 34 and telescopic grooves 35 on both sides of the outer wall of the connecting rod 32 meet the requirements, ensuring that the elastic buffer assembly 5 can be smoothly installed and move normally. Simultaneously, it is checked whether the compression spring 52 and buffer spring 58 in the elastic buffer assembly 5 have good elasticity and are free from deformation, breakage, etc., and whether the size and shape of components such as the moving block 51 and buffer block 55 meet the design standards, such as whether the arc at one end of the moving block 51 is regular, and whether the arcs of the buffer block 55 and the buffer groove 54 match.

[0033] Specifically, the outer wall of the connecting rod 32 is provided with grooves 34 on both sides, and a telescopic groove 35 is provided in the grooves 34. An elastic buffer component 5 is installed in the telescopic groove 35, and the elastic buffer component 5 moves in the grooves 34 and the telescopic groove 35.

[0034] Specifically, the elastic buffer assembly 5 includes a movable block 51, a compression spring 52 is installed between the bottom of the movable block 51 and the bottom of the telescopic groove 35, a movable limit strip 53 is provided on the bottom edge of the movable block 51, a telescopic limit frame 36 is provided at the opening of the telescopic groove 35, buffer grooves 54 are provided at the upper and lower ends of the movable block 51, and buffer blocks 55 are installed in the buffer grooves 54. The upper and lower buffer blocks 55 respectively contact the bottom surfaces of the drive shaft connecting plate 1 and the driven shaft connecting plate 2.

[0035] Specifically, a buffer limit strip 56 is provided at the bottom edge of the buffer block 55, a buffer limit frame 57 is provided at the opening of the buffer groove 54, and a buffer spring 58 is fixed between the bottom of the buffer block 55 and the bottom of the buffer groove 54.

[0036] Specifically, the buffer block 55 and the buffer groove 54 are both arc-shaped, the buffer limit strip 56 and the buffer limit frame 57 are also arc-shaped, and the top of the buffer block 55 is also provided with a buffer pad 59.

[0037] Specifically, one end of the movable block 51 is arc-shaped, and the bottom of the movable block 51 is provided with a positioning groove 511 for mounting the compression spring 52.

[0038] Specifically, the mounting ring 31 is fitted onto the front of the drive shaft connecting plate 1, and multiple connecting rods 32 are inserted into the connecting holes 4 and matched and fixed with the fastening nuts 33.

[0039] In this embodiment, the elastic buffer assembly 5 is installed on the connecting rod 32. First, the compression spring 52 is placed in the positioning groove 511 at the bottom of the moving block 51. Then, the moving block 51 together with the compression spring 52 is placed into the telescopic groove 35 of the connecting rod 32. At this time, the movement limiting strip 53 at the bottom edge of the moving block 51 should cooperate with the telescopic limiting frame 36 at the opening of the telescopic groove 35 to limit the movement range of the moving block 51 and prevent it from falling out of the telescopic groove 35.

[0040] Specifically, buffer blocks 55 are installed in the buffer grooves 54 at both ends of the movable block 51. A buffer spring 58 is fixed between the bottom of the buffer block 55 and the bottom of the buffer groove 54. The buffer limiting strip 56 at the bottom edge of the buffer block 55 must cooperate with the buffer limiting frame 57 at the opening of the buffer groove 54 to ensure stable movement of the buffer block 55 within the buffer groove 54. Finally, a buffer pad 59 is installed on top of the buffer block 55. Following the same method, elastic buffer components 5 are installed in the grooves 34 and telescopic grooves 35 on both sides of the outer wall of each connecting rod 32.

[0041] In this embodiment, the mounting ring 31 is fitted onto the front of the drive shaft connecting plate 1, so that the multiple connecting rods 32 on the mounting ring 31 are respectively aligned with the connecting holes 4 on the drive shaft connecting plate 1. Then, the multiple connecting rods 32 are inserted into the corresponding connecting holes 4 one by one, and the connecting rods 32 continue to pass through the connecting holes 4 on the driven shaft connecting plate 2.

[0042] Specifically, after all connecting rods 32 have passed through the corresponding connecting holes 4, the fastening nut 33 is tightened into the fixing groove 41 at the connecting hole 4 on the driven shaft connecting plate 2, and the driving shaft connecting plate 1 and the driven shaft connecting plate 2 are fixed by the threaded engagement of the fastening nut 33 and the connecting rod 32. During the tightening of the fastening nut, care must be taken to keep the mating surfaces of the driving shaft connecting plate 1 and the driven shaft connecting plate 2 parallel, ensuring that the buffer block 55 in the elastic buffer assembly 5 contacts the bottom surfaces of the driving shaft connecting plate 1 and the driven shaft connecting plate 2 on its upper and lower sides respectively.

[0043] In this embodiment, the assembly process of the coupling is clear, and the connection between the components is simple and reliable. The mounting ring 31 in the connecting assembly 3 can simultaneously drive multiple connecting rods 32 for installation, eliminating the need to position each connecting rod individually and reducing positioning time during installation. The fastening nut 33 is located in the fixing groove 41 at the connecting hole 4 on the driven shaft connecting plate 2, with a clear installation position, facilitating quick location of the installation point and tightening operation.

[0044] Specifically, the installation structure of the elastic buffer component 5 is reasonably designed, and the limiting fit between the components makes the installation process smooth, without the need for complicated adjustment procedures, which greatly shortens the overall assembly time and significantly improves the assembly efficiency.

[0045] In this embodiment, the elastic buffer assembly 5 plays a good buffering role during use. When the coupling is running, a certain relative movement or vibration will occur between the drive shaft connecting plate 1 and the driven shaft connecting plate 2. At this time, the compression spring 52 and the buffer spring 58 in the elastic buffer assembly 5 will undergo elastic deformation. The moving block 51 moves in the telescopic groove 35, and the buffer block 55 moves in the buffer groove 54. Through the synergistic effect of these components, vibration energy can be effectively absorbed and mitigated, reducing the impact and vibration transmission between the drive shaft and the driven shaft, and reducing the noise during equipment operation.

[0046] Specifically, the buffer pad 59 on the top of the buffer block 55 increases the contact area with the bottom surfaces of the drive shaft connecting plate 1 and the driven shaft connecting plate 2, avoiding excessive local wear. The arc design of the buffer block 55 and the buffer groove 54 also makes the buffering effect more uniform, further extending the service life of the coupling.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
