Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0033] As shown in Figures 1 to 8 The oiling and lubricating device for gear comprises a mechanical arm 1, a flow valve 2 connected to the mechanical arm 1, and a brush oil assembly 3 connected to the flow valve 2.

[0034] The brush oil assembly 3 comprises a brush oil base 17 provided with a containing groove 10, an oil outlet seat 6 arranged in the containing groove 10, a porous brush cloth 7 connected to the oil outlet seat 6, and an oil conveying pipe 8 connected to the brush oil base 17 in an extendable and retractable manner.

[0035] The porous brush cloth 7 is detachably connected to the oil outlet seat 6. The oil outlet seat 6 is detachably arranged in the containing groove 10. The oil outlet seat 6 is provided with an oil inlet 20 and a plurality of oil outlets 21 connected to the oil inlet 20. The oil conveying pipe 8 is detachably connected to the oil inlet 20. The porous brush cloth 7 is configured to allow the lubricating oil flowing out of the oil outlets 21 to flow from one side connected to the oil outlet seat 6 to the other side away from the oil outlet seat 6.

[0036] The mechanical arm 1 is capable of moving the porous brush cloth 7 along the tangent direction of the gear when the gear rotates, so that the lubricating oil on the porous brush cloth 7 is evenly coated on the gear.

[0037] The oiling and lubricating device further comprises a gear rotating assembly. The gear rotating assembly comprises a rotating driving member 19 and a three-jaw chuck 18 connected to the rotating driving member 19. The three-jaw chuck 18 is adapted to be clamped to the area outside the transmission teeth of the gear. The rotating driving member 19 is adapted to drive the three-jaw chuck 18 to rotate.

[0038] This utility model discloses a gear oiling and lubrication device that evenly distributes lubricating oil onto a porous brush cloth 7 via an oil outlet 6. The brush cloth then rubs along the tangential direction of the rotating gear, thus evenly coating the transmission teeth with lubricating oil and ensuring uniform application without localized accumulation.

[0039] Based on the above embodiments, in an optional embodiment of the present invention, such as... Figure 6 As shown, the side wall of the receiving groove 10 is provided with an oil seat disassembly port 9. An oil seat sliding groove is provided along the oil seat disassembly port 9 toward the interior of the receiving groove 10. The oil outlet seat 6 is configured to slidably engage with the oil seat sliding groove. An oil seat baffle 13 is provided on the side of the receiving groove 10 away from the oil seat disassembly port 9.

[0040] Specifically, the oil seat groove and oil seat baffle 13 restrict the freedom of the oil outlet 6, preventing it from detaching from the receiving groove 10 when applying lubricating oil. Preferably, a porous brush cloth 7 covers the upper surface of the oil outlet 6, with its edges embedded between the oil outlet 6 and the oil seat groove to further secure the porous brush cloth 7. The porous brush cloth 7 includes a base fabric with multiple through holes and brush bristles disposed on the base fabric. The through holes allow lubricating oil to pass through and flow to the brush bristles; the brush bristles can contact the transmission gears, further ensuring that the lubricating oil is evenly distributed on the transmission gears.

[0041] Based on the above embodiments, in an optional embodiment of the present invention, such as... Figures 4 to 6 As shown, the brushing assembly 3 further includes a side top block 15 located in the oil seat groove. The side top block 15 is configured to slidably engage with the brushing base 17 along the vertical direction of the oil seat groove, for abutting against the oil outlet 6. Preferably, the brushing base 17 is provided with a side slide 5 for the side top block 15 to slide, and a side limiting portion 4 located in the side slide 5. The side top block 15 is provided with a first elastic portion 14 and a second elastic portion 16. The first elastic portion 14 and the second elastic portion 16 can abut against the side limiting portion 4, for driving the side top block 15 toward the interior of the receiving groove 10.

[0042] In this embodiment of the invention, the first elastic part 14 and the second elastic part 16 integrated into the side top block 15 drive the side top block 15 to move toward the receiving groove 10, which can reduce the number of parts and lower production costs. In other embodiments, an elastic element 11 such as a spring can be used instead of the elastic part, and this invention does not specifically limit this.

[0043] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 6As shown, the oil-brushing component 3 further includes an elastic member 11 located at the bottom of the accommodation groove 10, and a bottom block 12 joined to the bottom of the elastic member 11. The bottom block 12 is adapted to abut against the oil outlet seat 6 from the bottom of the accommodation groove 10. Preferably, the number of the bottom blocks 12 is 4. Each bottom block 12 is joined to 2 elastic members 11. By driving the bottom block 12 with the elastic member 11 to clamp the oil outlet seat 6, the oil outlet seat 6 can be well fixed.

[0044] Based on the above embodiments, in an optional embodiment of the present invention, as Figure 8 shown, the circumference of the gear to be coated with lubricating oil is set as d. The working length of the porous brush cloth 7 is The working width of the porous brush cloth 7 is not less than the tooth width of the gear to be coated with lubricating oil. Preferably, the distance between two adjacent oil outlet holes 21 along the length direction of the oil outlet seat 6 is

[0045] As Figure 8 shown, the oil inlet 20 is configured as a flared structure (i.e., Y-shaped design) so that the lubricating oil can flow out evenly to the left and right sides. A flow channel connecting the oil inlet 20 and the oil outlet holes 21 is arranged in the oil outlet seat 6; the flow channel is configured as a "field" - shaped structure; the diameters of the 2 cross - shaped flow channels in the middle are larger than the flow channels surrounded by the outer circle, so that the lubricating oil can flow evenly to each oil outlet hole 21, and the coordinated design of the aperture and the hole depth position ensures that the lubricating oil efficiently covers the felt.

[0046] Preferably, the working length of the porous brush cloth 7 is so that there is enough coating distance during the gear coating process, ensuring that the grease adheres more evenly to the gear to be coated. The design of the spacing of the oil outlet holes 21 simultaneously satisfies the uniform oil seepage and ensures the consistency of the oil supply amount for each part during the gear coating process.

[0047] The diameters of the 2 cross - shaped flow channels in the middle are to ensure sufficient oil supply at the center of the felt and ensure that the oil seepage state of the felt expands from the center to the outside. The diameters of the flow channels surrounded by the outer circle are to cooperate with the oil outlet to ensure the uniformity of the oil seepage of the felt. The thickness of the porous brush cloth 7 plus the oil outlet seat 6 is to ensure that during the oil seepage process, the grease adheres to the upper surface without penetrating to the bottom surface.

[0048] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
