[0023] The utility model provides a coupling cover, such as Figure 1-Figure 3 As shown, it includes an outer cover 1 and an inner cover 2. The outer cover 1 includes a small connecting ring 11 and a large connecting ring 12. The small connecting ring 11 and the large connecting ring 12 form a stepped structure, which greatly reduces the weight of the coupling cover, reduces costs and makes installation more convenient. The small connecting ring 11 and the large connecting ring 12 are connected by a side sealing plate 13. The small connecting ring 11 slides with the inner cover 2 and is locked and fixed by a hexagonal head bolt 4. A waist-shaped hole 21 is provided on the side of the inner cover 2 to facilitate free adjustment of the installation length of the coupling cover and eliminate the installation influence caused by the assembly error in the length direction of the coupling. The end of the inner cover 2 away from the outer cover 2 is fixed on the gear box housing, and the end of the outer cover 1 away from the inner cover 2 is fixed on the flywheel housing of the diesel engine. The coupling cover adopts a stepped structure formed by the small connecting ring 11 and the large connecting ring 12. This design greatly reduces the overall weight of the coupling cover, not only reduces the manufacturing cost, but also makes the installation and operation process more convenient. Due to the adoption of a lightweight stepped structure, the use of materials is reduced, thereby effectively reducing production costs and improving the market competitiveness of the product. The sliding fit design between the small connecting ring 11 and the inner cover 2, and the locking fixation achieved by the hexagonal head bolt 4, make the installation process of the coupling cover simpler and faster, and improve the installation efficiency. The waist-shaped hole 21 set on the side of the inner cover 2 allows the installation length of the coupling cover to be freely adjusted. This design effectively eliminates the installation impact caused by the assembly error in the length direction of the coupling, and improves the adaptability and versatility of the product. One end of the inner cover 2 of the coupling cover is fixed to the gearbox housing, and one end of the outer cover 1 is fixed to the flywheel housing of the diesel engine, forming a stable and reliable protective structure, which effectively prevents the coupling from accidentally flying out during operation and protects the personal safety of the operator.

[0024] In this embodiment, the outer cover 1 and the inner cover 2 are composed of two symmetrical parts, and the sides of the two parts are integrally formed with connecting plates. The connecting plates of the upper and lower parts are fixed by bolts to facilitate disassembly and assembly operations.

[0025] Specifically, a flange plate 14 is installed on one side of the large connecting ring 12 , and the flange plate 14 is fixed to the flywheel housing of the diesel engine by bolts, so as to facilitate the installation and fixation of the outer cover 1 .

[0026] Furthermore, a plurality of through holes are provided on the surface of the side sealing plate 13 to facilitate observation of whether the rotating component rotates normally.

[0027] Furthermore, a baffle 22 is installed at one end of the inner cover 2, a circular hole is provided in the middle of the baffle 22, and a sealing ring 3 is installed in the circular hole to ensure a tight fit when connected to the gear box, thereby forming a firm and safe protection.

[0028] Furthermore, the outer diameter of the inner cover 2 is adapted to the inner diameter of the outer cover 1, and the outer wall of one end of the inner cover 2 is fitted on the inner wall of the outer cover 1, which facilitates the relative sliding of the inner cover 2 and the outer cover 1 and the flexible length adjustment of the coupling cover.

[0029] Furthermore, the waist-shaped hole 21 is a long strip structure, and the waist-shaped hole 21 is slidably matched with the side hexagonal head bolt 4 of the inner cover 2, and one end of the hexagonal head bolt 4 is locked and fixed by a washer and a nut.

[0030] Furthermore, the outer cover 1 and the inner cover 2 are both welded with spark-free copper alloy plates to ensure the strength of the outer cover 1 and the inner cover 2.

[0031] The coupling cover of this utility model is composed of an outer cover 1 and an inner cover 2, both of which are designed as two symmetrical parts, making them easy to disassemble and repair. The outer cover 1 includes a small connecting ring 11 and a large connecting ring 12, forming a stepped structure that reduces weight and costs. The small connecting ring 11 slides with the inner cover 2 and can be locked and fixed with hexagonal bolts 4, allowing for flexible length adjustment.

[0032] Installation process:

[0033] First, fix one end of the inner cover 2 to the gearbox housing to ensure a tight fit. Then, slide the small connecting ring 11 of the outer cover 1 with the inner cover 2, and adjust the installation length of the coupling cover as needed to eliminate the assembly error in the length direction of the coupling. The waist-shaped hole 21 is designed to facilitate sliding between the small connecting ring 11 and the inner cover 2. Use the hexagonal head bolt 4 to pass through the waist-shaped hole 21 on the side of the inner cover 2, and add a washer and nut to lock and secure it to ensure the stability and safety of the coupling cover. Finally, bolt the end of the outer cover 1 away from the inner cover 2 to the diesel engine flywheel housing through the flange plate 14 to complete the installation of the entire coupling cover.

[0034] During use, the coupling cover can effectively prevent the coupling from accidentally flying out and protect the personal safety of the operator.

[0035] The through holes on the side sealing plate 13 allow easy observation of whether the rotating components are rotating normally. If the coupling cover needs to be disassembled or repaired, the inner cover 2 and the outer cover 1 can be easily separated by simply loosening the hexagonal bolts 4.
