[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-2 As shown, a gearbox lubrication structure includes a gearbox 1, the lower end of the gearbox 1 is fixedly connected to four matrix-distributed support columns 2, the lower left part of the front end of the gearbox 1 is fixedly connected to a mounting plate 3, and the upper end of the mounting plate 3 is fixedly installed with a circulation component 4. Through the provided circulation component 4, the lubricant inside the gearbox 1 can be sucked out with the assistance of the spray component 5, and then the lubricant is sprayed out at the upper end of the gearbox 1 through the spray component 5, thereby realizing the recycling of the lubricant and improving the utilization rate of the lubricant. The output end of the circulation component 4 is fixedly installed with a spray component 5. Through the provided spray component 5, after the lubricant inside the gearbox 1 is sucked out by the circulation component 4, it can be sprayed into the inner cavity of the gearbox 1 from the upper end of the gearbox 1 again, so that the surface of the parts inside the gearbox 1 can be evenly adhered to the lubricant, thereby improving the lubrication effect.

[0026] In order to achieve the purpose of continuous recycling of the lubricant in the inner cavity of the gear box 1, refer to Figure 1-5 The circulation component 4 includes a double-cavity box 1 41 fixedly connected to the upper end of the mounting plate 3, a gasket 42 fixedly connected to the rear end of the double-cavity box 1 41, and the inner cavity of the double-cavity box 1 41 is rotatably connected to two mutually meshing cylindrical gears 43, and the rear end of the gasket 42 is fixedly connected to the double-cavity box 2 44. The right side of the middle part of the rear end of the double-cavity box 2 44 is rotatably connected to a driving rod 45. The front surface of the driving rod 45 passes through the double-cavity box 2 44 and extends to the inner cavity of the cylindrical gear 43 on the right side and is fixedly connected to it. The two cylindrical The maximum outer diameter of the gear 43 is equal to the inner diameter of the inner cavity of the double-cavity box 1 41, the size of the gasket 42 is larger than that of the double-cavity box 1 41, the size of the double-cavity box 1 41 is equal to that of the double-cavity box 2 44, and the middle of the upper end of the double-cavity box 1 41 and the double-cavity box 2 44 are both provided with an output hole 46 communicating with the inner cavity of the two, and the middle of the lower end of the double-cavity box 1 41 and the double-cavity box 2 44 are both provided with an input hole 47 communicating with the inner cavity of the two, and the two cylindrical gears 43 are jointly located in the cavity formed by the output hole 46 and the double-cavity box 2 44.

[0027] Furthermore, the spray assembly 5 includes an output pipe 51, which is fixedly connected to the cavity formed by the two output holes 46. The front end of the output pipe 51 is fixedly connected to a three-outlet pipe 52, which passes through the middle of the upper end of the gear box 1 and extends to the inner cavity of the gear box 1. The lower end of the three-outlet pipe 52 is fixedly connected to three spray mechanisms 54 in a linear array. An input pipe 53 is fixedly connected to the cavity formed by the two input holes 47, and the other end of the input pipe 53 passes through the middle of the lower end of the gear box 1 and extends to the inner cavity of the gear box 1.

[0028] During installation, the present invention only requires the rear end of the driving rod 45 to be fixedly connected to any output end of the inner cavity of the gearbox 1, and this output end will not affect the operation of other components inside the gearbox 1.

[0029] When the output end drives the driving rod 45 to rotate, the driving rod 45 drives the cylindrical gear 43 fixedly connected thereto to rotate, thereby causing the two cylindrical gears 43 to mesh with each other. As can be seen from the above, the two cylindrical gears 43 are jointly located in the cavity formed by the output hole 46 and the double-cavity box 2 44, and the two cylindrical gears 43 are rotationally connected to the inner cavity of the double-cavity box 1 41. At the same time, the output tube 51 is fixedly connected to the cavity formed by the two output holes 46. The maximum outer diameter of the two cylindrical gears 43 is equal to the inner diameter of the inner cavity of the double-cavity box 1 41. The input tube 53 is fixedly connected to the cavity formed by the two input holes 47. Therefore, when the two cylindrical gears 43 are driven to mesh with each other and rotate, the meshing between the two cylindrical gears 43 will form a sealed cavity at the inlet formed by the two input holes 47.

[0030] During this process, the volume of the cavity gradually increases, generating negative pressure, which causes the lubricant in the inner cavity of the gearbox 1 to flow from the input pipe 53 into the cavity formed by the output hole 46 and the second double-chamber box 44;

[0031] As the two cylindrical gears 43 continue to rotate, the meshing between the two cylindrical gears 43 gradually moves to the cavity formed by the two output holes 46. During this process, the volume of the cavity gradually decreases, causing the lubricant to be pushed into the cavity formed by the two output holes 46. The lubricant can then be discharged from the output pipe 51 fixedly connected in the cavity formed by the two output holes 46, and then can be sprayed into the inner cavity of the gear box 1 through the three outlet pipes 52 in the three spraying mechanisms 54, thereby making the lubricant evenly sprayed on the surface of the components in the inner cavity of the gear box 1, thereby improving the lubrication effect;

[0032] When the lubricant sprayed on the surface of the component gradually flows to the bottom of the inner cavity of the gear box 1, as the two cylindrical gears 43 continue to rotate, the suction and discharge stages are continuously alternated, thereby achieving continuous delivery of the lubricant. The lubricant is sealed in the meshing gap between the two cylindrical gears 43 to prevent backflow;

[0033] As can be seen from the above, the size of the gasket 42 is larger than the size of the double chamber box 1 41, and the size of the double chamber box 1 41 and the double chamber box 2 44 are equal, so the overall sealing of the circulation component 4 is better.

[0034] It should be noted that the conveying capacity of the circulation assembly 4 depends on factors such as the size, meshing mode and rotation speed of the two cylindrical gears 43.

[0035] The spraying mechanism 54 mentioned above is a nozzle in the prior art. When the lubricating oil enters the nozzle, when the pressure in the nozzle reaches a sufficient pressure, the lubricant inside the nozzle can be sprayed out in the form of water mist, thereby making the lubricant sprayed more evenly on the surface of the components installed in the inner cavity of the gear box 1.

[0036] For this reason, the spraying mechanism 54 is of conventional design in the prior art and will not be elaborated in detail in this solution.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
