[0002] A coupling is a mechanical part used to connect the driving shaft and the driven shaft in different mechanisms so that they rotate together to transmit torque. In high-speed and heavy-load power transmission, some couplings, such as elastic couplings, also have the functions of buffering, vibration reduction and improving the dynamic performance of the shaft system.
[0003] Due to the unevenness of the output torque, the torsional vibration of the shaft system is caused, so a highly elastic coupling is needed to reduce wear. However, most couplings have poor buffering effect when in use, and the output torque is low, and they cannot effectively play a buffering role. The equipment is easily damaged, which brings inconvenience to the user and is not conducive to use. Therefore, an elastic coupling with good buffering effect is proposed to solve the above problem.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-2 In this embodiment, an elastic coupling with good buffering effect includes two mounting seats 1, and the mounting seats 1 are used to position the driving shaft 8 and the driven shaft 9, so as to facilitate fixation and effectively improve the overall practicality. The internal sliding connection of the mounting seat 1 is provided with a fixing component 2 for fixing. The fixing component 2 includes a push rod slidably connected to the mounting seat 1, and a control block is fixed on the top of the push rod. A friction strip is fixed on the outer surface of the control block. The control block and the friction strip make it more convenient to push the push rod to rotate, further improving the overall practicality.
[0022] In addition, the outer surface of the push rod is threadedly connected with two push blocks that are slidably connected to the mounting seat 1. Two sections of threaded strips with opposite threads are fixed on the outer surface of the push rod. Threaded holes matching the threaded strips are provided inside the two push blocks. Because the two sections of threaded strips are opposite, when the push rod rotates, the two non-rotatable push blocks will move in relative directions along the push rod, thereby fixing the active shaft 8 and the driven shaft 9. The interior of the push block is fixed with a fixing rod that passes through the inner cavity of the mounting seat 1. Rubber pads are fixed on the opposite sides of the two fixing rods. The rubber pads are natural rubber pads, which can effectively prevent damage when fixing the active shaft 8 and the driven shaft 9, and effectively improve the stability of the fixation.
[0023] Furthermore, sliding blocks are fixed on the opposite sides of the two fixed rods, and a sliding groove slidably connected to the sliding block is opened inside the mounting seat 1. The sliding groove and the sliding block effectively improve the stability of the movement of the fixed rod. A connecting seat 3 is fixed on the opposite side of the two fixed components 2. The connecting seat 3 effectively plays a connecting role, and the diameter of the connecting seat 3 is larger than the diameter of the driving shaft 8 and the driven shaft 9, thereby effectively reducing the impact of vibration. A buffer component 4 is fixed on the right side of the left connecting seat 3, and the buffer component 4 is used to play a buffering role.
[0024] In addition, a positioning rod 5 is fixed to the right side of the left connecting seat 3, and the positioning rod 5 effectively plays a positioning role. The outer surface of the positioning rod 5 is plugged with an elastic body 6 fixed to the right connecting seat 3. When the positioning rod 5 pushes the elastic body 6 to rotate, the elastic force of the elastic body 6 can effectively play a certain buffering role. A buffer groove compatible with the positioning rod 5 is opened on the left side of the elastic body 6. A plug rod 7 plugged with the buffer assembly 4 is fixed to the left side of the right connecting seat 3. A limit block is fixed on the outer surface of the plug rod 7. The buffer rod 404 can push the limit block to move, so that normal transmission can be achieved. An inclined surface is provided on the left side of the limit block. The inclined surface is convenient for pushing the buffer rod 404 to move, so that the whole is more stable. A driving shaft 8 is fixed inside the left mounting seat 1, and a driven shaft 9 is fixed inside the right mounting seat 1. Fixed grooves are opened on the upper and lower sides of the driving shaft 8 and the driven shaft 9. The fixed grooves make the fixation of the fixing rod more stable, so that the driving shaft 8 and the driven shaft 9 are not easy to separate from the whole.
[0025] In general, by rotating the push rod, the two fixing rods can fix the driving shaft 8 and the driven shaft 9, and because the two fixing rods move the same distance, the driving shaft 8 and the driven shaft 9 can be fixed at the center of the mounting base 1, and the arranged elastomer 6 can effectively play a buffering role. The overall structure is simple, which makes the overall operation more stable and effectively improves the overall practicality.
[0026] See also Figure 3 In order to improve the overall buffering performance, the buffer component 4 in this embodiment includes an insert block 401 fixed to the connecting seat 3. The insertion of the insert block 401 and the insert rod 7 can play a certain positioning effect. A buffer block 402 is fixed inside the insert block 401, and a buffer spring 403 is fixed inside the buffer block 402. The elastic force of the buffer spring 403 can play a certain buffering role. A buffer rod 404 that penetrates to the outside of the buffer block 402 is fixed on the side of the buffer spring 403 away from the buffer block 402. The buffer rod 404 is inside the buffer block 402, so that the buffer rod 404 has a certain moving space, so that the buffer spring 403 can play a normal buffering role. A sponge pad 405 is fixed on the side of the buffer rod 404 away from the buffer spring 403.
[0027] In general, when the buffer rod 404 pushes the limit block on the insertion rod 7 to rotate, the buffer spring 403 will contract, thereby playing a normal buffering role. The overall structure is simple, and it can effectively play a buffering role together with the elastomer 6, thereby making the transmission more stable, effectively protecting the equipment, and making the overall more stable.
[0028] The working principle of the above embodiment is:
[0029] First, the two mounting seats 1 are respectively sleeved on the outer surfaces of the active shaft 8 and the driven shaft 9. By rotating the pushing rod inside the left mounting seat 1, the two pushing blocks can drive the two fixing rods to move, thereby fixing the active shaft 8. At this time, move the mounting seat 1 on the right side to make the positioning rod 5 and the elastic body 6 plugged in. During the movement, the plug rod 7 and the plug block 401 are plugged in. After the connection is completed, the driven shaft 9 can be fixed by the fixing component 2. When the active shaft 8 rotates and drives the driven shaft 9 to rotate, the elastic force of the buffer spring 403 and the elastic body 6 can play a certain buffering role together. The overall structure is simple, which effectively improves the buffering effect and effectively protects the equipment, making the overall structure more convenient to use.
