[0028] As Figures 1-4 shown, a lateral shock-absorbing toothed chain drive system proposed by the present utility model includes a toothed disc 1. The connecting shaft at the center of the toothed disc 1 is connected to an external driving device. It also includes a chain 2, and the chain 2 meshes with the toothed disc 1. The chain 2 includes multiple sets of link plate structures 3. The link plate structure 3 includes an installation box 4 and a connecting plate 5. When the toothed disc 1 rotates, the chain 2 rotates accordingly. When the chain 2 rotates, each set of link plate structures 3 contacts the tooth blocks on the toothed disc 1 respectively.
[0029] Among them, the link plate structure 3 further includes a moving plate 6 slidably installed on one side of the installation box 4. One side of the installation box 4 is open, and the moving plate 6 is slidably installed on the open side of the installation box 4. First connection holes 41 are opened on both sides of the installation box 4. There are two sets of connecting plates 5, and second connection holes 51 are opened on both sides of the connecting plate 5. Third connection holes 61 are opened at the corresponding positions of the moving plate 6. The first connection holes 41, the second connection holes 51, and the third connection holes 61 are all used for installing connection pins 7.
[0030] In addition, a connection pin 7 is rotatably installed between the two sets of connecting plates 5. The connection pin 7 passes through the second connection holes 51, the third connection holes 61, and the first connection holes 41. Block 71 is provided at both ends of the connection pin 7, and the block 71 is used to prevent the connection pin 7 from slipping off.
[0031] In this embodiment, the shock-absorbing component includes a fixing plate 8 fixedly installed in the installation box 4. The shock-absorbing component further includes fixing rods 11 fixedly installed on both sides of the fixing plate 8. Moving cylinders 9 are slidably installed at the ends of the two sets of fixing rods 11 away from the fixing plate 8. Pressure plates 10 are fixedly installed on the sides of the moving cylinders 9 away from the fixing plate 8. When the moving plate 6 slides on one side of the installation box 4, the pressure plates 10 also move, driving the moving cylinders 9 to slide on the fixing rods 11, thereby applying force to the spring 12 fixedly connected between the fixing plate 8 and the limiting plate 91.
[0032] Among them, one set of pressure plates 10 tightly presses against the inner side of the moving plate 6, and the other set of pressure plates 10 tightly presses against the side of the installation box 4 away from the moving plate 6. A rubber ring 62 is fixedly installed on the inner side of the moving plate 6, and the rubber ring 62 is used to absorb the force generated when the moving plate 6 contacts the installation box 4, thereby reducing the wear of the moving plate 6.
[0033] In addition, circular plates 111 are fixedly installed at one ends of the fixed rods 11 far away from the fixed plate 8. A limiting plate 91 is fixedly installed at one end of the moving cylinder 9 close to the fixed rod 11. The limiting plate 91 is used to prevent the moving cylinder 9 from slipping off the fixed rod 11 and improve the stability during use.
[0034] Finally, the diameter of the circular plate 111 is 1-2 mm larger than the diameter of the fixed rod 11. A circular hole through which the fixed rod 11 can pass is formed in the center of the limiting plate 91. Springs 12 are fixedly installed between the limiting plate 91 and the fixed plate 8. The springs 12 are sleeved on the outer sides of the fixed rods 11. Under the action of the springs 12, the moving plate 6 and the connecting plate 5 always squeeze the tooth blocks at the corresponding positions on the tooth disc 1, reducing the gap between the link plate structure 3 and the tooth blocks, thereby reducing the lateral impact and vibration generated when the chain 2 and the tooth disc 1 rotate, reducing the wear of the chain 2, and increasing the service life of the toothed chain.
[0035] Working principle: During the working process of the present utility model, the connecting shaft at the center of the tooth disc 1 is connected to an external driving device to drive the rotation of the tooth disc 1, thereby causing the chain 2 meshing with the tooth disc 1 to rotate. When the chain 2 rotates, each link plate structure 3 contacts the tooth blocks on the tooth disc 1 respectively, causing the moving plate 6 to slide on one side of the installation box 4, thereby causing the pressure plate 10 pressed against the inner side of the moving plate 6 to move, driving the moving cylinder 9 fixedly connected to the pressure plate 10 to slide on the fixed rod 11, applying force to the spring 12 fixedly connected between the fixed plate 8 and the limiting plate 91. Under the action of the spring 12, the moving plate 6 and the connecting plate 5 always squeeze the tooth blocks at the corresponding positions on the tooth disc 1, reducing the gap between the link plate structure 3 and the tooth blocks, thereby reducing the lateral impact and vibration generated when the chain 2 and the tooth disc 1 rotate, reducing the wear of the chain 2, and increasing the service life of the toothed chain. At the same time, during assembly, the damping component can be assembled outside the installation box 4 and then the fixed plate 8 can be fixedly installed in the installation box 4, reducing the inconvenience of assembly caused by the small size of the installation box 4 and improving the convenience during assembly and processing.
[0036] The above specific embodiments are only several alternative embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
