Technical Field

[0001] This utility model relates to the field of gear production equipment technology, specifically to an oil immersion device for gear production. Background Technology

[0002] Before leaving the factory after processing, gears need to undergo an oil immersion process. The purpose is to attach a layer of oil film to the surface of the gears to enhance their protection and prevent wear, corrosion, oxidation and other problems during transportation and use.

[0003] A search revealed a Chinese patent with publication number CN220195335U that discloses an oil-immersing device for gear production, comprising a housing and a placement basket. The housing has vertical rods on both the left and right sides, and a horizontal rod between the tops of the two vertical rods. Several hydraulic cylinders are located at the bottom of the horizontal rod, and piston rods are located at the bottom of the hydraulic cylinders. A connecting plate is located at the bottom of the piston rods, and electromagnets are located on both the left and right sides of the bottom of the connecting plate. The number of placement baskets corresponds to the number of hydraulic cylinders, and iron blocks corresponding to the electromagnets are located on the top of the left and right sides of the placement baskets.

[0004] In traditional devices, gears are mostly stationary or can only achieve simple movement in one direction. It is difficult for oil to fully penetrate the complex structures such as the tooth grooves and channels of the gears, which easily leads to incomplete local oil immersion and affects the quality of oil immersion. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0017] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0018] Please see Figure 1 , Figure 2 , Figure 3 The present invention relates to an oil immersion device for gear production, comprising an oil immersion tank 1, a fixing frame 4 inside the oil immersion tank 1, one end of the fixing frame 4 being rotatably mounted on the oil immersion tank 1 via a sleeve 2, a drive source 13 being provided between one end of the sleeve 2 and the oil immersion tank 1, a vertical rod 5 being rotatably mounted on the fixing frame 4, a fixing component being provided at one end of the vertical rod 5, the fixing component including a fixing plate 8 being mounted on the vertical rod 5 and inserted into the vertical rod 5.

[0019] See Figure 3 , Figure 4 As shown, a fixing bolt 11 is provided between the fixing plate 8 and the vertical rod 5. One end of the fixing bolt 11 passes through the fixing plate 8 and the vertical rod 5, and a hexagonal nut 12 is provided on the fixing bolt 11. The fixing bolt 11 and the hexagonal nut 12 are threadedly connected. A support rod 9 is fixedly installed on the fixing plate 8. The surface of the support rod 9 is chrome-plated to enhance wear resistance and smoothness and reduce scratches when the gear inner hole contacts the support rod 9. The end is provided with a rounded transition to facilitate quick gear insertion.

[0020] In this embodiment, a fastening nut 10 is provided on the support rod 9. The fastening nut 10 is threadedly connected to the support rod 9. Rubber gaskets are provided on the side of the fastening nut 10 that is close to the fixing plate 8. By increasing the friction, the nut is prevented from loosening during the rotation of the gear, and the metal nut is prevented from directly pressing the gear surface and causing indentation, thus protecting the gear precision. A drive assembly is provided at the other end of the vertical rod 5. The drive assembly includes a drive shaft 3.

[0021] See Figure 1 , Figure 2 , Figure 4As shown, one end of the drive shaft 3 is rotatably connected to the sleeve 2, and the other end of the drive shaft 3 is set on the oil immersion tank 1. The height of the drive shaft 3 is slightly higher than the oil level in the oil immersion tank 1. The sleeve 2 and the drive shaft 3 are coaxially arranged. The drive shaft 3 is rotatably connected to the oil immersion tank 1. The oil immersion tank 1 is equipped with a controller 15. An angle sensor is set between the sleeve 2, the drive shaft 3 and the oil immersion tank 1.

[0022] A second drive source 14 is provided between the oil immersion tank 1 and the drive shaft 3. Both the first drive source 13 and the second drive source 14 are preferably AC servo motors, which have the characteristics of adjustable speed, precise positioning and stable output torque, and can meet the fine adjustment requirements of revolution angle and rotation speed. The servo motor is connected to the sleeve 2 and the drive shaft 3 through a reduction gearbox. By reducing the speed and increasing the torque, drive jamming caused by excessive gear weight is avoided, ensuring smooth revolution and rotation.

[0023] See Figure 2 , Figure 3 , Figure 4 As shown, a bevel gear 6 is mounted on the drive shaft 3, and a bevel gear 7 is mounted on the vertical rod 5. The bevel gear 6 and the bevel gear 7 mesh and drive each other. There are multiple vertical rods 5, which are evenly distributed. A horizontal plate 16 is provided at one end of the vertical rod 5 near the bevel gear 7. The two ends of the horizontal plate 16 are fixedly mounted on the fixed frame 4. The vertical rod 5 is rotatably connected to the horizontal plate 16. The two ends of the vertical rod 5 are restricted by the horizontal plate 16 and the fixed frame 4, thereby improving the stability of the vertical rod 5 during operation.

[0024] The implementation principle is as follows: According to the specifications of the gear to be immersed in oil, the fixing components are replaced. By pulling out the fixing bolt 11, the fixing plate 8 is removed from the vertical rod 5. Then, the fixing plate 8 of the corresponding specifications is replaced, the fixing bolt 11 is reinserted and the hexagonal nut 12 is tightened to secure the fixing plate 8 to the vertical rod 5, ensuring that the gear can be completely immersed in the oil in the immersion tank 1. The inner hole of the gear is fitted onto the support rod 9, and the fastening nut 10 is rotated to make it fit against the surface of the gear. The pre-tightening force of the threaded connection firmly fixes the gear to the support rod 9, preventing the gear from falling off or shaking during the immersion process. The controller 15 on the oil immersion tank 1 presets parameters such as immersion time, revolution angle, and rotation speed. The controller 15 synchronously activates the angle sensors at the sleeve 2 and drive shaft 3 to monitor the motion angle in real time and provide feedback data. The controller 15 controls the first drive source 13 to work, which drives the sleeve 2 to rotate around its axis, thereby driving the fixed frame 4 to revolve around the sleeve 2. The multiple vertical rods 5 and gears on the fixed frame 4 revolve synchronously with the fixed frame 4, causing the gears to move along a circular trajectory in the oil, expanding the contact range with the oil. At the same time, the controller 15 controls the second drive source 14 to work, which drives the drive shaft 3 to rotate. The first bevel gear 6 on the drive shaft 3 meshes with the second bevel gear 7 on the vertical rod 5, causing the vertical rod 5 to rotate around its own axis, thereby causing the gears fixed on the support rod 9 to rotate synchronously. The angle sensor transmits the rotational data of the sleeve 2 and the drive shaft 3 to the controller 15 in real time. The controller 15 dynamically adjusts the output power of the drive source 13 and the drive source 2 14 according to the preset parameters, accurately controls the orbital trajectory range and rotational speed, ensures that all parts of the gear are evenly immersed in oil, and avoids oil splashing or gear loosening caused by excessive movement.

[0025] After the oil immersion time reaches the preset value, the controller 15 controls the drive source 13 and drive source 2 14 to stop working, and the fixed frame 4 is reset to the initial position under the action of the sleeve 2; the operator unscrews the fastening nut 10 and removes the oil-immersed gear from the support rod 9 to complete one oil immersion operation.

[0026] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
