Description

Technical Field

[0001] This utility model relates to the field of coupling technology, specifically to an assembly structure for a high-horsepower coupling. Background Technology

[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, allowing them to rotate together during motion and power transmission, and remaining connected under normal conditions. Sometimes it is also used as a safety device to prevent the connected components from bearing excessive loads, thus providing overload protection.

[0003] In the field of agricultural machinery, the power transmission system of equipment such as harvesters is crucial. With the increasing scale and mechanization of agricultural production, the demand for high-horsepower engines in agricultural machinery is constantly growing. As a key component for transmitting power between the engine and working parts, the performance of the coupling directly affects the working efficiency and reliability of the equipment. Under high-horsepower transmission conditions, the elastic elements of traditional couplings, particularly the design of the driving and driven discs, are not well adapted to the power output characteristics of high-horsepower engines, resulting in low power transmission efficiency. Utility Model Content

[0026] Please see Figure 1-6 This utility model provides a technical solution: an assembly structure for a high-horsepower coupling, including a driving disc structure 1, a driven disc structure 2, and an elastic element structure 3 disposed between the driving disc structure 1 and the driven disc structure 2.

[0027] The active disc structure 1 includes an active disc body 101. A plurality of first locking blocks 102 are evenly arranged on the inner side of the active disc body 101, and a reinforcing ring 103 is arranged on the outer side of the active disc body 101. A first reinforcing rib 104 is arranged between the reinforcing ring 103 and the active disc body 101. By adding the outer reinforcing ring 103 and the first reinforcing rib 104, it can better connect with the high-horsepower engine shaft for power output, making it better suited to the power output of the high-horsepower engine, improving power transmission efficiency, and avoiding power loss due to connection problems.

[0028] The passive disk structure 2 includes a passive disk body 201. Several second locking blocks 202 are evenly arranged on the inner side of the passive disk body 201. A docking groove 203 is provided in the middle of the passive disk body 201. A second reinforcing rib 204 is provided between the outer side of the docking groove 203 and the passive disk body 201. By providing the second reinforcing rib 204 on the outer side of the docking groove 203, stability can be further improved.

[0029] The elastic element structure 3 includes an elastic body 301, with several elastic protrusions 302 disposed on the outer side of the elastic body 301. The elastic element addresses the problem of excessive vibration and impact during high-horsepower transmission in the coupling, protecting the engine and working parts, and extending the equipment's service life.

[0030] Furthermore, the first card block 102 has a first card slot 1021 on both sides, and a first limiting stop 1022 is provided on the inner side of the first card slot 1021. The first card slot 1021 is used to cooperate with the elastic protrusion 302, and the first limiting stop 1022 is used to limit the elastic protrusion 302.

[0031] Furthermore, the second locking block 202 has a second locking groove 2021 on both sides, and a second limiting stop 2022 is provided on the inner side of the second locking groove 2021. The second locking groove 2021 is used to cooperate with the elastic protrusion 302, and the second limiting stop 2022 is used to limit the elastic protrusion 302.

[0032] Furthermore, there are six first locking blocks 102, two second locking blocks 202, and twelve elastic protrusions 302. The first locking blocks 102 and the second locking blocks 202 are arranged in an interleaved manner, and the elastic protrusions 302 are located between adjacent first locking blocks 102 and second locking blocks 202. This staggered arrangement improves the buffering effect.

[0033] Furthermore, the reinforcing ring 103 is provided with several mounting holes 1031, which are used to fix the coupling to external equipment with bolts.

[0034] Furthermore, a positioning keyway is provided on the inner side of the mating groove 203 to cooperate with the spline of the connecting shaft for easy installation.

[0035] In summary, the active disc employs a combination of an outer reinforcing ring 103 and a radial first reinforcing rib 104, significantly improving the connection rigidity with the high-horsepower engine shaft. The passive disc enhances structural stability through a second reinforcing rib 204 surrounding the mating groove 203. A dual-limiting system, with the first and second limit stops 1022 precisely constraining the movement of the elastic element, is used. Twelve elastic protrusions 302, along with six plus two staggered locking blocks, form a multi-level buffer unit. The elastic body 301 uses a double-sided slot design to achieve three-dimensional vibration absorption, and the asymmetrical locking block layout (6:2) creates the optimal damping gradient. The reinforcing ring 103 has pre-set standardized mounting holes 1031, supporting quick bolt fixing. The positioning keyway enables center-alignment installation of the spline shaft without adjustment.
