Description

Technical Field

[0001] The utility model relates to the field of transmission chains, in particular to a high-strength deformation-resistant transmission chain. Background Art

[0002] Chains are generally metal links or rings, mostly used for mechanical transmission and traction. They are chain-shaped objects used to block traffic passages (such as in streets, rivers or harbor entrances). Chains used for mechanical transmission are classified according to the basic structure of the chain, that is, according to the shape of the components, the parts and positions that mesh with the chain, the size ratio between the parts, etc., belonging to the chain product series. There are many types of chains, and most chains are composed of chain plates, chain pins, bushings and other components. Chain plates will bend due to mutual accumulation, extrusion and collision, so the chain plates need to be leveled.

[0003] According to the published patent 202222078233.6, a high-strength and deformation-resistant transmission chain includes a chain connecting plate, the chain connecting plate is movably mounted with a chain body through a first latch, an oil storage tank is opened on the top of the chain body, oil storage cotton is arranged inside the oil storage tank, an oil brush is fixedly installed in the middle position inside the chain body, an anti-corrosion coating is provided on the chain connecting plate and the chain body, and a second latch is movably mounted on the chain body. In the process of realizing the utility model, the inventor found that at least The following problems have not been solved. The problem of chain rusting and jamming is solved by anti-corrosion coating, first latch, chain body, second latch, arc cover, fixing bolt, oil storage tank, oil storage cotton, connecting hole and oil brush. During use, the traditional transmission chain rivets both ends of the transmission shaft to the external connecting plate, which easily causes the transmission shaft to wear or break and is inconvenient to replace. The operator takes a long time to replace parts of the transmission chain and the labor intensity of the operator when replacing the transmission chain is relatively high, which reduces the convenience of the transmission chain when disassembling and assembling. For this reason, a new technical solution needs to be designed to solve it. Utility Model Content

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a high-strength and deformation-resistant transmission chain, including an external connecting plate and an internal connecting plate, both of which are provided with through holes of the same size, a transmission shaft is installed inside the through hole, a pressure-resistant sleeve is provided on the outside of the transmission shaft, threaded holes are provided at both ends of the transmission shaft, limiting sleeves are installed at both ends of the transmission shaft, countersunk holes are provided inside the limiting sleeves, and the inside of the countersunk holes is connected to limiting bolts through damping pads.

[0006] Preferably, the outer diameter of the transmission shaft matches the inner diameter of the insertion hole, and is slidably connected to the inner wall thereof.

[0007] Preferably, the inner diameter of the pressure-resistant sleeve matches the outer diameter of the transmission shaft and is rotatably connected to the outside thereof, and both ends of the pressure-resistant sleeve are rotatably connected between the two internal connection plates.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model combines threaded holes, limiting sleeves, countersunk holes, damping pads and limiting bolts. When the transmission chain is assembled, firstly, the through holes on a set of external connecting plates are made to correspond to the through holes on the internal connecting plates, then the transmission shaft is passed into the inside of the through holes, then the compression sleeve is sleeved on the outside of the transmission shaft, then the other end of the transmission shaft is passed through the through holes of another set of external connecting plates and the internal connecting plates, then the limiting sleeve is sleeved on the outside of the transmission shaft, then a countersunk hole is aligned with a threaded hole, and then the limiting bolt is passed through the inside of the damping pad. , then insert the limit bolt and the damping pad into the inside of one end of the countersunk hole, and finally tighten the limit bolt into the threaded hole to limit the position of the limit sleeve, thereby realizing the assembly installation of the transmission shaft on the transmission chain, avoiding the phenomenon that the transmission shaft is worn or broken due to riveting the two ends of the transmission shaft on the external connecting plate and is inconvenient to replace, saving the operator's time in replacing parts of the transmission chain and reducing the operator's labor intensity in replacing the transmission chain, and improving the convenience of disassembly and assembly of the transmission chain;

[0013] By adding a damping pad in the countersunk hole, the limit bolt can be prevented from loosening from the threaded hole due to long-term vibration of the transmission chain, thereby improving the firmness of the limit bolt after installation and fixation. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0019] Example 1: A high-strength, anti-deformation transmission chain, see Figures 1 to 3, including an external connecting plate 1 and an internal connecting plate 11, both of which are provided with insertion holes 12 of the same size, a transmission shaft 13 is installed inside the insertion hole 12, the outer diameter of the transmission shaft 13 is consistent with the inner diameter of the insertion hole 12, and is slidably connected to the inner wall thereof, and a pressure-resistant sleeve 14 is provided outside the transmission shaft 13, the inner diameter of the pressure-resistant sleeve 14 is consistent with the outer diameter of the transmission shaft 13, and is rotatably connected to the outside thereof, and the two ends of the pressure-resistant sleeve 14 are rotatably connected to two Between the internal connecting plates 11, threaded holes 15 are provided at both ends of the transmission shaft 13, and limit sleeves 16 are installed at both ends of the transmission shaft 13. The inner diameter of the limit sleeve 16 matches the outer diameter of the transmission shaft 13 and is slidably connected to the outside of the transmission shaft 13. A countersunk hole 17 is provided inside the limit sleeve 16, and the inside of the countersunk hole 17 is connected to a limit bolt 19 through a damping pad 18. When the transmission chain is assembled, firstly, the through holes 12 on a set of external connecting plates 1 are aligned with the internal connecting plates 11. The transmission shaft 13 is passed into the insertion hole 12, and the compression sleeve 14 is sleeved on the outside of the transmission shaft 13. The other end of the transmission shaft 13 is passed through the insertion holes 12 of another set of external connecting plates 1 and the internal connecting plates 11, and the limiting sleeve 16 is sleeved on the outside of the transmission shaft 13. A countersunk hole 17 is aligned with a threaded hole 15, and a limiting bolt 19 is passed through the inside of the damping pad 18, and then the limiting bolt 19 and the damping pad 18 are inserted into one end of the countersunk hole 17. Finally, the limiting bolt 19 is tightened inside the threaded hole 15 to limit the position of the limiting sleeve 16, thereby realizing the assembly installation of the transmission shaft 13 on the transmission chain, avoiding the phenomenon that the two ends of the transmission shaft 13 are riveted on the external connecting plate 1, which causes the transmission shaft to be worn or broken and is inconvenient to replace, saving the time of operators when replacing parts of the transmission chain and reducing the labor intensity of operators when replacing the transmission chain, and improving the convenience of disassembly and assembly of the transmission chain;
