[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This application provides a coupling for a tape reel truck, which solves the problem that common couplings on the market are prone to thermal deformation and detachment during use due to the high pressure, high temperature and high torque characteristics of the hydraulic tape reel truck's working environment, resulting in high overall replacement costs.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] This utility model discloses a tape-wound automotive coupling, according to the attached... Figures 1-4 As shown, the coupling includes two sets of half-couplings 1 and an intermediate disc 2 installed between the two sets of half-couplings 1. Both sides of the intermediate disc 2 are provided with protruding teeth 22, and the two sets of protruding teeth 22 are perpendicular to each other. The end of the protruding teeth 22 away from the intermediate disc 2 expands to both sides so that the cross section of the protruding teeth 22 is trapezoidal. The half-coupling 1 includes a fitting 11 and a toothed disc 12 integrally formed at the end of the fitting 11. The toothed disc 12 is provided with a trapezoidal slot 16 adapted to the protruding teeth 22, so that the intermediate disc 2 is assembled with the trapezoidal slot 16 on the half-coupling 1 through the trapezoidal protruding teeth 22 on both sides. This prevents the two sets of half-couplings 1 and the intermediate disc 2 from axially moving, avoiding the situation where axial movement impacts the half-couplings 1 and the intermediate disc 2, causing deformation and increasing the assembly gap, thus preventing them from falling off.

[0026] The intermediate disk 2 has a heat-conducting component 23 inside, and multiple heat-conducting pipes 25 arranged in a ring array on the outer wall of the intermediate disk 2. The inner end of the heat-conducting pipe 25 contacts the heat-conducting component 23 to conduct heat from the intermediate disk 2 outward, so that the heat from the intermediate disk 2 can be transferred to the heat-conducting pipe 25 through the heat-conducting component 23 and diffused outward, improving the heat dissipation effect. At the same time, the modular assembly design reduces replacement costs.

[0027] A shaft slot 13 is provided through the middle of the assembly 11 and the gear plate 12, and transmission grooves 14 are symmetrically opened on both sides of the inner wall of the shaft slot 13. The design of two sets of transmission grooves 14 allows the other set of transmission grooves 14 to be used when one set of transmission grooves 14 is worn, thereby extending the service life of the half coupling 1.

[0028] The outer diameter of the fitting 11 near the chainring 12 increases gradually to provide a stronger anti-torsional deformation effect between the fitting 11 and the chainring 12, thus preventing the fitting 11 from tortuous deformation and tearing during high torque use.

[0029] A retaining ring 15 is integrally formed inside the shaft slot 13 near the middle disk 2. The retaining ring 15 abuts against the end of the heat-conducting component 23, so that the heat-conducting component 23 can be kept inside the middle disk 2 and prevent it from sliding into the shaft slot 13.

[0030] The middle plate 2 has an assembly groove 26 adapted to the heat-conducting component 23 in the middle part, and multiple heat-conducting grooves 24 adapted to the heat-conducting pipe 25 are formed on the outer wall of the middle plate 2. The inner end of the heat-conducting groove 24 extends into the assembly groove 26. The diameter of the assembly groove 26 is larger than the length of the heat-conducting pipe 25. The inner diameter of the heat-conducting groove 24 is tapered from the inside to the outside. The outer diameter of the heat-conducting pipe 25 is adapted to the inner diameter of the heat-conducting groove 24, so that the heat-conducting pipe 25 can be directly put into the assembly groove 26 and then assembled from the assembly groove 26 into the heat-conducting groove 24. The heat-conducting groove 24 is thicker inside and thinner outside, so that the heat-conducting pipe 25 can be stuck in the heat-conducting groove 24 to prevent it from falling off.

[0031] Both the heat pipe 25 and the heat-conducting component 23 are made of pure copper, which has a better heat conduction effect. The half coupling 1 and the intermediate plate 2 are made of tungsten steel or alloy steel, which has stronger hardness and anti-torsional deformation effect.

[0032] Working principle: In use, the two sets of half-couplings 1 are connected to the drive shaft and driven shaft of the winding cart respectively through shaft slots 13. At the same time, the intermediate plate 2 is assembled with the trapezoidal slots 16 on the half-couplings 1 through trapezoidal protrusions 22 on both sides. This prevents the two sets of half-couplings 1 and the intermediate plate 2 from axially moving, avoiding axial movement and impact that could cause deformation of the half-couplings 1 and the intermediate plate 2, resulting in increased assembly gaps and detachment. At the same time, a heat-conducting component 23 is set in the middle of the intermediate plate 2, and a heat-conducting pipe 25 is set on the outer wall of the intermediate plate 2. The heat-conducting pipe 25 is inserted outward from the assembly slot 26 into the heat-conducting groove 24. The retaining ring 15 inside the shaft slot 13 positions the heat-conducting component 23, so that the heat on the intermediate plate 2 can be transferred to the heat-conducting pipe 25 through the heat-conducting component 23 and diffused outward, improving the heat dissipation effect. The modular assembly design reduces replacement costs.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
