At the same time, the rotating horizontal axis drives the gear to be coated to rotate, so that the spray nozzle can continuously apply grease to the gear to be coated, ensuring that the grease is applied to the gear more evenly, ensuring that the gear surface is fully lubricated, and reducing the wear of the gear during use.

[0018] 3. The present invention fixes the gear to be coated on the rotating horizontal axis by setting a positioning component, and places the gear to be coated on the supporting arc plate at the top. When gear 2 drives the threaded rod to rotate, the transmission structure drives several supporting arc plates to move simultaneously, and the gear to be coated is pressed tightly by several supporting arc plates, so that the gear to be coated remains fixed, which helps to make the gear to be coated more stable when grease is applied, ensures that a consistent amount of grease can be applied each time, and reduces the risk of insufficient or excessive lubrication.

[0019] 4. The present invention sets a driving component to first drive the positioning component to fix the gear to be coated on the rotating horizontal axis, and then synchronously drives the rotating horizontal axis and the extrusion coating component to operate, so that grease is applied while the gear to be coated rotates. By simultaneously driving the operation of multiple structures by a servo motor, the design of the entire coating device can be simplified, the complexity of production and maintenance can be reduced, and the coating device can ensure the reliability and stability of the device while improving efficiency.

[0039] When the rotating horizontal axis 22 rotates, the connecting shaft 2373 is driven to rotate through the transmission belt 2375, and the connecting shaft 2373 drives the movable turntable 2372 at one end thereof to rotate. The movable turntable 2372 drives the bottom end of the movable pull rod 2371 to rotate around the connecting shaft 2373, and the movable pull rod 2371 drives the movable connecting rod 236 at its top to slide downward, and the movable connecting rod 236 drives the L-shaped plate 235 to move downward in the spray tank 234, and the L-shaped plate 235 discharges the grease through the spray nozzle 231.
