Description

Technical Field

[0001] This utility model relates to the field of buffer couplings, and more particularly to a buffer coupling. Background Technology

[0002] In modern industrial production, couplings are widely used in the transmission systems of mechanical equipment to connect the power source and the working machine. The main functions of couplings are to transmit torque, compensate for relative displacement between the two shafts, buffer and dampen vibrations, and absorb impact loads. With the development of industrial technology, the performance requirements for couplings are becoming increasingly stringent, especially in high-speed, heavy-load, and high-impact and high-vibration working environments, where traditional rigid couplings can no longer meet the requirements.

[0003] A search revealed Chinese Patent Publication No. CN213575234U, which discloses a buffer coupling, relating to the field of coupling technology. This utility model includes an upper coupling, an inner buffer device, a lower coupling, a connecting device, and an outer buffer device. The upper coupling includes an upper shaft seat, which is a hollow cylinder. The lower surface of the upper shaft sleeve has a first retaining tooth. The inner buffer device includes a first gasket, a diaphragm, and a second gasket. The side surface of the first gasket connects to the inner surface of the upper shaft seat. Both the upper and lower surfaces of the diaphragm have grooves, and the groove on the upper surface of the diaphragm slides in engagement with the first retaining tooth. The lower coupling includes a lower shaft seat, one surface of which has a mounting hole. This utility model provides a buffer coupling by using gaskets to reduce axial impact during the engagement of two shafts, using springs to mitigate axial impact, and using diaphragms and buffer cylinders to reduce radial load damage to the shafts. A connecting shell facilitates disassembly of the coupling.

[0004] The above-mentioned device has the following defects: when the coupling collides with the external equipment, it will shake due to the impact of kinetic energy, causing the components on the equipment to fall off, which reduces the vibration resistance and buffering effect of the equipment. Therefore, a buffer coupling is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a buffer coupling, which aims to improve the problem that poor buffering after collision in the prior art couplings may cause some electronic components to fall off.

[0007] As a further description of the above technical solution: the auxiliary component includes an auxiliary seat, the upper surface of which has multiple sets of evenly distributed positioning grooves, and limit blocks are fixedly installed at both ends of the lower surface of the auxiliary seat. A button is detachably connected to the upper surface of the limit block, and a gasket is detachably connected to the lower surface of the limit block.

[0008] As a further description of the above technical solution: the top end of the spring is fixedly connected to the lower surface of the adjusting plate, and the bottom end of the spring is fixedly connected to the upper surface of the fixed plate.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 - Figure 2 One embodiment of this utility model is a buffer coupling, including a mounting base 1, which supports and positions the equipment. An output shaft 2 is provided at the center of the mounting base 1, which serves as a power source for the equipment. An auxiliary component 4 is provided on the upper surface of the mounting base 1, and a buffer component 3 is provided at the upper end of the auxiliary component 4.

[0024] Reference Figure 1 - Figure 3The buffer assembly 3 includes an electric telescopic rod 32, which is detachably connected to the upper surface of the adjusting disc 33. The impact force is transmitted through the electric telescopic rod 32 to the adjusting disc 33. The adjusting disc 33 is fixedly mounted at the bottom end of the electric telescopic rod 32, causing the adjusting disc 33 to shift under the impact force. A through-post 34 is connected through a groove on the upper surface of the adjusting disc 33, exerting a compressive force on the spring 35. The through-posts 34 are evenly distributed in a circumferential array on the lower surface of the adjusting disc 33. The bottom of the through-post 34 is engaged in the inner wall groove of the positioning groove 42, causing the spring... The spring 35 deforms to generate elastic force, absorbing the impact force. The lower surface of the adjusting plate 33 is elastically connected to the fixed plate 36 via the spring 35. The top end of the spring 35 is fixedly connected to the lower surface of the adjusting plate 33, and the bottom end of the spring 35 is fixedly connected to the upper surface of the fixed plate 36. This buffers and absorbs the vibration of the output shaft 2, improving the stability of the equipment. The outer wall of the output shaft 2 is connected through the inner ring of the adjusting plate 33, preventing the impact force from directly acting on the output shaft 2 and causing the output shaft 2 to break. This enhances the protective effect of the equipment on the output shaft 2.

[0025] Reference Figure 1 - Figure 3 The auxiliary component 4 includes an auxiliary seat 41, which is detachably connected to the inner wall of a groove on the upper surface of the mounting base 1. When the operator needs to maintain the equipment, by pressing the button 431, multiple evenly distributed positioning grooves 42 are opened on the upper surface of the auxiliary seat 41. Limiting blocks 43 are fixedly installed at both ends of the lower surface of the auxiliary seat 41, so that the button 431 pushes the gasket 432 in the limiting block 43, thereby unlocking the limiting block 43 in the groove of the mounting base 1. The upper surface of the limiting block 43 is detachably connected to the button 431, which realizes the function of quick disassembly of the auxiliary seat 41. The separation of the auxiliary seat 41 realizes the function of disassembling the buffer component 3. The lower surface of the limiting block 43 is detachably connected to the gasket 432, which improves the convenience of the operator in maintaining the equipment parts, so that the entire equipment does not need to be replaced when repairing or replacing parts, reducing the maintenance cost of the equipment and increasing the service life of the parts in the equipment.

[0026] Working principle: When the output shaft 2 is impacted, the adjusting disc 33 absorbs the impact force and compresses the spring 35, causing the spring 35 to deform and generate elastic force, which absorbs the impact force and buffers the vibration of the output shaft 2, improving the stability of the equipment and preventing the output shaft 2 from breaking due to direct impact force. This enhances the protective effect of the equipment on the output shaft 2. When the operator needs to maintain the equipment, pressing the button 431 causes the button 431 to push the gasket 432 in the limit block 43, unlocking the limit block 43 in the groove of the mounting seat 1. This enables the quick disassembly of the auxiliary seat 41. The separation of the auxiliary seat 41 allows the buffer assembly 3 to be disassembled, improving the convenience of the operator in maintaining the equipment parts. When repairing or replacing parts, the entire equipment does not need to be replaced, reducing maintenance costs and increasing the service life of the parts.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
