[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figure 1-4As shown, a transversely mounted reduction gearbox includes a housing 1 and a gear assembly 2. The gear assembly 2 includes a first transmission gear 21, a second transmission gear 22, a third transmission gear 23, a fourth transmission gear 24, and a fifth transmission gear 25. The first transmission gear 21, the second transmission gear 22, the third transmission gear 23, the fourth transmission gear 24, and the fifth transmission gear 25 are sequentially meshed and arranged laterally side by side within the housing 1. The first transmission gear 21 meshes with the drive gear 31 of a motor 3. One end of the fifth transmission gear 25 has an output gear 251 protruding outside the housing 1. The housing 1 and the output shaft 30 of the motor 3 are arranged spatially perpendicularly, so that the motor 3 and the housing 1 together form an L-shaped structure. The other end of the fifth transmission gear 25 has a large gear 252 that meshes with the fourth transmission gear 24. The upper surfaces of the large gear 252 and the second transmission gear 22 are respectively provided with spiral-shaped oil reservoirs 200. The oil reservoir adopts a spiral structure design, which guides the lubricant from one side to the other, resulting in better lubrication and cooling, thus improving the lubrication effect of the gear assembly. The height of the first transmission gear 21 is the same as that of the second transmission gear 22, the height of the third transmission gear 23 is the same as that of the fourth transmission gear 24, the height of the second transmission gear 22 is greater than that of the fourth transmission gear 24, and the height of the fifth transmission gear 25 is greater than that of the fourth transmission gear 24. This staggered distribution of the five transmission gears makes the entire gearbox structure more compact and balanced. This ensures the stability of the meshing of the five transmission gears, thereby reducing vibration and noise and extending the service life of the reduction gearbox.

[0022] like Figure 1-3As shown, the housing 1 includes a base 11 and a cover 12 detachably connected to the base 11. A receiving cavity 100 for housing the gear assembly 2 is formed between the base 11 and the cover 12. The base 11 is provided with a sealing groove 111 surrounding the gear assembly 2. A sealing ring 13 is provided in the sealing groove 111 to abut against the cover 12, forming a sealing fit between the base 11, the cover 12, and the sealing ring 13. The cover and the base are detachably connected, which facilitates the assembly of the reduction gearbox. The sealing ring enhances the sealing performance of the housing, effectively preventing lubricant leakage and improving lubrication. Multiple fixing ears 112 are provided on the base 11 corresponding to the outer side of the sealing groove 111. Multiple screws 113 connected to the cover 12 are provided on the fixing ears 112. Placing the fixing ears on the outer side of the sealing groove improves the sealing performance of the housing. The cover 12 has an opening 121 for exposing the output gear 251. Multiple mounting ears 122 are provided on the cover 12, and each mounting ear 122 has a mounting hole 123. The multiple mounting holes on the cover facilitate the installation of the reduction gearbox, making installation more convenient. The base 11 has a through hole 113 through which the output shaft 30 of the motor 3 passes. The output shaft 30 passes through the through hole 113 and extends into the receiving cavity 100. The base 11 has multiple snap-fit ​​posts 114 that engage with the motor 3. The drive gear 31 is mounted on the output shaft 30. The motor and base are assembled using a snap-fit ​​method, facilitating assembly. A sealing groove 115 is provided inside the base 11 corresponding to the output shaft 30 of the motor 3. A sealing gasket 116 is provided in the sealing groove 115 to seal against the base 11 and the output shaft 30. The sealing gasket enhances the sealing performance of the gearbox, preventing lubricating oil leakage and thus improving the lubrication effect of the gear assembly. An annular boss 117 is provided inside the housing 11 at the gear shafts 201 of the first transmission gear 21, second transmission gear 22, and fifth transmission gear 25. One end of the gear shafts 201 of the first transmission gear 21, second transmission gear 22, and fifth transmission gear 25 passes through the annular boss 117, which also contains an oil reservoir 118. The oil reservoir stores lubricating oil, ensuring the lubrication effect of the gear assembly. Furthermore, the annular boss strengthens the housing, enabling it to withstand greater torque on the gear shafts and extending the service life of the reduction gearbox.

[0023] like Figure 4 As shown, a spiral-shaped oil storage groove 202 is provided on the outer peripheral wall of one end of the gear shaft 201. The oil storage groove adopts a spiral structure design. When the gear shaft rotates, the oil storage groove can guide the lubricating oil in the oil storage chamber to the second transmission gear and the fifth transmission gear, thereby improving the lubrication effect of the gear assembly.

[0024] The gear assembly of this reduction gearbox adopts a transverse structure design, with the gearbox and motor forming an L-shape. This effectively reduces the axial space occupied, and the five transmission gears are arranged horizontally side by side, facilitating automated assembly of the gearbox. Furthermore, the oil reservoir features a spiral design, which not only stores lubricating oil but also guides it from one side to the other, resulting in better lubrication and cooling, thus enhancing the lubrication performance of the gear assembly.
