Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3 As shown, the present invention includes a housing 1, a compression groove 2, a male rotor 3, a female rotor 4, and a bearing 5. The compression groove 2 is located on the left side of the inner wall of the housing 1. The bearing 5 is fixedly connected to the top and bottom of the left side of the inner wall of the compression groove 2. The male rotor 3 is located at the bottom of the inner wall of the compression groove 2, and the female rotor 4 is located at the top of the compression groove 2.

[0024] refer to Figure 3 Gear 7 is provided on the top left side of the inner wall of the movable groove 61. The inner wall of gear 7 is fixedly connected to the right side of the female rotor 4.

[0025] As a technical optimization of this utility model, by setting gear 7, when the male rotor 3 rotates, it will drive gear 8 to rotate, and when gear 8 rotates, it will drive gear 7 to rotate, and gear 7 will drive the female rotor 4 to rotate to work in coordination.

[0026] refer to Figure 3 Gear 2 8 is provided at the bottom left side of the inner wall of the movable groove 61, and the inner wall of gear 2 8 is fixedly connected to the right side of the male rotor 3.

[0027] As a technical optimization of this utility model, by setting gear 2 8, the male rotor 3 is driven to rotate by a motor, the male rotor 3 drives gear 2 8 and gear 3 9 to rotate, and gear 2 8 drives gear 1 7 to rotate.

[0028] refer to Figure 3 Gear 3 9 is provided at the bottom right side of the inner wall of the movable groove 61, and gear 3 9 is fixedly connected to the surface of the male rotor 3.

[0029] As a technical optimization of this utility model, by setting gear three 9, gear three 9 can drive gear four 10 to rotate synchronously when rotating. When the teeth of gear one 7 or gear two 8 are damaged, gear four 10 can drive the female rotor 4 to rotate synchronously, so that the female rotor 4 can continue to work together.

[0030] refer to Figure 3 A gear 4 10 is provided on the top right side of the inner wall of the movable groove 61. A bearing 3 11 is fixedly connected to the right side of the inner wall of the gear 4 10. A tooth groove 12 is provided on the left side of the inner wall of the gear 4 10.

[0031] As a technical optimization of this utility model, by setting gear four 10, bearing three 11 and tooth groove 12, after the teeth of gear one 7 or gear two 8 are damaged, the gear four 10 moves to the left, so that one side of the female rotor 4 is inserted into the tooth groove 12. When the gear four 10 rotates, it will drive the female rotor 4 to rotate.

[0032] refer to Figure 3 A fixing block 13 is fixedly connected to the right side of the inner wall of the storage slot 63. A limiting groove 14 is opened on the left side of the fixing block 13. A motor 15 is fixedly connected to the right side of the inner wall of the limiting groove 14. A screw 16 is fixedly connected to the output end of the motor 15.

[0033] As a technical optimization of this utility model, by setting a fixing block 13, a limiting groove 14, a motor 15 and a screw 16, the limiting groove 14 can fix the motor 15, the motor 15 can drive the screw 16 to rotate, and the rotation direction of the screw 16 can be controlled by controlling the rotation direction of the motor 15. At the same time, the limiting groove 14 can limit the fixing post 17.

[0034] refer to Figure 3A fixing post 17 is provided on the left side of the inner wall of the limiting groove 14. The left side of the fixing post 17 is fixedly connected to the inner ring of the bearing 11. The inner wall of the fixing post 17 is threadedly connected to the surface of the screw 16.

[0035] As a technical optimization of this utility model, by setting a fixed column 17, the fixed column 17 is pushed to the left by the screw 16 during use. Then, the rotation of the gear 4 10 is not affected by the bearing 3 11. The gear 4 10 is inserted into the tooth groove 12 on one side of the female rotor 4, so that the gear 4 10 can drive the female rotor 4 to rotate together, reducing the load on the gear 1 7 and the gear 2 8, and avoiding damage to the gear 2 8 and the gear 1 7.

[0036] The working principle and usage process of this utility model are as follows: During use, bearing 5 supports one side of the male rotor 3 and female rotor 4, allowing for smoother rotation of the two rotors. It also limits the rotation of the male rotor 3 and female rotor 4, preventing vibration. The movable slot 61 fixes bearing 62, which supports the other side of the male rotor 3 and female rotor 4. The storage slot 63 stores gear 10, providing space for its movement. When the male rotor 3 rotates, it drives gear 8 to rotate, which in turn drives gear 7. Gear 7 drives the female rotor 4 to rotate in synergy. The motor drives the male rotor 3 to rotate, which in turn drives gears 8 and 9 to rotate. Gear 8 drives gear 7 to rotate, and gear 9, in turn, drives gear 4 to rotate synchronously. When the teeth of gear 28 are damaged, gear 4 can drive the female rotor 4 to rotate synchronously, allowing the female rotor 4 to continue working together. After the teeth of gear 17 or gear 28 are damaged, gear 410 moves to the left, causing one side of the female rotor 4 to insert into the tooth groove 12. When gear 410 rotates, it will drive the female rotor 4 to rotate. The limiting groove 14 can fix the motor 15, which can drive the screw 16 to rotate. By controlling the rotation direction of the motor 15, the rotation direction of the screw 16 can be controlled. At the same time, the limiting groove 14 can limit the fixed column 17. In use, the screw 16 pushes the fixed column 17 to move to the left, and then the bearing 31 can prevent the rotation of gear 410 from being affected. By inserting one side of the female rotor 4 into the tooth groove 12, gear 410 can drive the female rotor 4 to rotate together, reducing the load on gear 17 and gear 28 and preventing damage to gear 28 and gear 17.

[0037] In summary, this water-cooled screw chiller unit's twin-screw synergistic compression structure, through the inclusion of bearing 5, supports one side of both the male rotor 3 and the female rotor 4, allowing for smoother rotation of the two rotors. Bearing 5 also limits the movement of the male and female rotors 3 and 4, preventing vibration during rotation. This solves the problem of existing synergistic compression mechanisms that typically rely on two gears for transmission to ensure the coordinated operation of the twin screws. However, this transmission method has a significant drawback: if one gear fails, the entire transmission system becomes paralyzed and unable to continue operation. This not only leads to equipment downtime, affecting normal production and cooling needs, but also significantly increases maintenance costs and time, making it extremely inconvenient to use.
