[0021] The embodiments provided by this utility model are as follows: Figures 1-5 As shown, a multi-axis reducer for stirring includes a housing 1. The top of the housing 1 has several first input ports 2, and the bottom has several output ports 3. The number and position of the first input ports 2 and output ports 3 are matched. Several first drive motors 4 are fixedly mounted on the top of the housing 1. Couplings 5 ​​are fixedly connected to the output ends of the first drive motors 4. The couplings 5 ​​pass through the housing 1 and extend to the bottom of the housing 1. The couplings 5 ​​are rotatably connected to the first input ports 2 and output ports 3 respectively. Extension portions 9 are integrally formed on the left and right sides of any end of the housing 1. The top of the extension 9 is provided with a second input port 11. A second drive motor 12 is fixedly installed on the top of the extension 9. The output end of the second drive motor 12 passes through the second input port 11 and extends into the extension 9. Worms 6 are horizontally arranged on both sides inside the housing 1. A first bevel gear 13 is fixedly sleeved on the output end of the second drive motor 12. A second bevel gear 14 that meshes with the first bevel gear 13 is fixedly sleeved on the worm 6. A first helical gear 8 is fixedly sleeved on the coupling 5. Any worm 6 meshes with the adjacent first helical gear 8.

[0022] In use, the operator starts several first drive motors 4 fixed to the top of the housing 1. The output shaft of each motor begins to rotate, and the power is directly transmitted through the coupling 5. The upper end of the coupling 5 is rotatably connected to the housing 1 through the first input port 2, and the lower end is connected to the output port 3, extending outward. The lower extension of each coupling 5 can be directly connected to a stirring element. Therefore, each first drive motor 4 independently drives a stirring element to rotate, realizing multi-axis stirring. At the same time, or one of the second drive motors 12 fixed to the top of the extensions 9 on the left and right sides of the housing 1 is started. The output shaft of the second drive motor 12 rotates, and the first bevel gear 13 fixed on the output shaft of the second drive motor 12 rotates accordingly, driving the second bevel gear 14 meshing with it and fixed on the worm gear 6. This meshing will... The vertical rotational motion is converted into horizontal rotational motion, driving two worm gears 6 arranged horizontally inside the housing 1 to rotate. Each rotating worm gear 6 meshes with a first helical gear 8 fixed on several adjacent couplings 5. Through the meshing transmission between the worm gear 6 and the first helical gear 8, the rotational power of the worm gear 6 is transmitted to each coupling 5 that meshes with it, thereby driving the stirring components on these couplings 5 ​​to rotate further at high speed. This multi-axis reducer realizes multi-axis output in a compact space, can install multiple stirring components at the same time, quickly mix materials, shorten the mixing time, reduce the original 2 hours of mixing to 0.5 hours, improve work efficiency, and can provide different speeds for different stirring components according to actual use requirements to meet the mixing needs under different working conditions.

[0023] Preferably, a hollow sleeve 15 that rotates around its own axis is vertically arranged on the housing 1.

The second helical gear 16 is arranged inside the housing 1. A third helical gear 17 that matches the second helical gear 16 is fixedly sleeved on any coupling 5. The sleeve 15 is used to connect the stirring component. Through the transmission of the second helical gear 16 and the third helical gear 17, the stirring component connected to the sleeve 15 is driven to rotate. Through this transmission method, the stirring component on the sleeve 15 rotates slowly.

[0024] Preferably, the sleeve rod 15 is located at the center of the housing 1, and several first drive motors 4 are arranged around the sleeve rod 15. The centrally symmetrical layout makes the force on each transmission component uniform, reduces vibration and wear caused by off-center load, significantly improves the stability and life of the equipment operation, and this arrangement makes the overall structure more compact, the power transmission path is the shortest, and the energy loss is minimal. It is particularly suitable for high-performance mixing equipment with extremely high requirements for mixing uniformity.

[0025] Preferably, two rolling bearings 18 are fixedly sleeved on the coupling 5. The coupling 5 is connected to the first input port 2 and the output port 3 respectively through the rolling bearings 18, which ensures high precision and low resistance in the rotation of the coupling 5.

[0026] Preferably, a plurality of support bearings 20 are fixedly sleeved on the worm 6. The support bearings 20 are fixedly installed inside the housing 1. The support bearings 20 provide additional support points for the worm 6, effectively reducing the deflection deformation of the worm 6 under heavy load and the vibration problem at the critical speed, and effectively improving the reliability and torque bearing capacity of the equipment.

[0027] Preferably, handles 21 are fixedly provided at the front and rear ends of the top of the housing 1. The handles 21 enable the reducer to be easily hoisted, positioned and moved, which greatly reduces the difficulty of installation and the workload of maintenance.

[0028] The multi-axis reducer for mixing of this utility model has several first drive motors 4 fixedly installed on the top of the housing 1. The output end of the first drive motor 4 is fixedly connected to the coupling 5. Worms 6 are horizontally arranged on both sides inside the housing 1.
