DETAILED DESCRIPTION

[0018] ​The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-3 As shown, a planetary gear module with good lubrication includes a gear ring 1, a sun gear 2 disposed inside the gear ring 1, a drive shaft 3 passing through the sun gear 2, the drive shaft 3 being fixed to the sun gear 2, and three planetary gears 4 meshing between the sun gear 2 and the gear ring 1. An oil filling groove 5 is formed on the top surface of the gear ring 1, a rotating block 6 is disposed within the oil filling groove 5, a threaded block 9 is disposed within the oil filling groove 5, a rubber plug 10 is fixedly installed below the threaded block 9, an arc-shaped channel 11 is provided below the oil filling groove 5, a lubrication hole 12 passes through the arc-shaped channel 11, an oil-absorbing felt 13 is fixedly installed within the lubrication hole 12, and an oil-absorbing felt 13 is fixedly installed above the oil-absorbing felt 13. There is a rubber plug 14, and a T-shaped rod 15 is fixedly installed below the oil-absorbing felt 13. The bottom of the rubber plug 10 is provided with a strip groove 16 that passes through the threaded block 9. Both ends of the gear ring 1 are provided with T-shaped grooves 17 that are the same as the arc-shaped channel 11. The bottom of the T-shaped groove 17 is fixedly installed with an oil-absorbing felt 18. A rubber plug 19 is provided on the outside of the oil-absorbing felt 18. A T-shaped rod 20 is provided in the T-shaped groove 17. A rubber plug 21 is fixedly installed at the front end of the T-shaped rod 20. A strip groove 22 is provided at the bottom of the rubber plug 21. A locking block 23 is fixedly installed at the outer end of the strip groove 22. The locking block 23 is engaged with the T-shaped groove 17.

[0020] Furthermore, the oil filling groove 5 is provided with internal threads, and the threaded block 9 is threadedly connected to the oil filling groove 5.

[0021] Through the above technical solution, the threaded connection ensures that the threaded block 9 and the oil filling groove 5 are tightly connected through the interlocking of the threads. During the operation of the planetary gear module, even when subjected to external forces such as vibration and impact, the threaded connection can provide reliable fastening force, effectively preventing the threaded block 9 from loosening or falling out of the oil filling groove 5.

[0022] Furthermore, a cylindrical groove 7 is provided on the top of the rotating block 6, and a cross groove 8 is provided in the cylindrical groove 7.

[0023] Through the above technical solution, the cylindrical groove 7 provides a specific installation position for the cross groove 8, and its cylindrical shape can restrict the movement of the cross groove 8 in the horizontal direction, so that the cross groove 8 can be accurately installed in the predetermined position.

[0024] Furthermore, the bottom of the oil filling groove 5 and the rubber plug 10 are in the shape of an inverted trapezoid.

[0025] Through the technical scheme, the inverted trapezoidal shape makes the contact area between the rubber plug and the oil injection groove gradually increase as the rubber plug goes deeper when being inserted into the bottom of the oil injection groove, and the rubber material itself has a certain elasticity. Under this shape cooperation, the rubber plug will be deformed by the extrusion of the oil injection groove wall, so as to be closely attached to the inner wall of the oil injection groove and effectively fill the small gap between them.

[0026] Further, the oil absorption felt two 18 is located outside the planetary gear 4.

[0027] Through the technical scheme, the oil absorption felt two 18 has the ability to absorb and store lubricating oil, and is located outside the planetary gear 4, so that it is closer to the friction part. When the planetary gear 4 operates, the oil absorption felt two 18 can release the absorbed lubricating oil to the surface of the planetary gear 4 in time, providing continuous lubrication for it.

[0028] Further, the T-shaped rod two 20 extends through the oil absorption felt two 18 and the rubber plug three 19 into the strip-shaped groove two 22.

[0029] Through the technical scheme, the T-shaped rod two 20 penetrates through the oil absorption felt two 18, which limits the movement of the oil absorption felt two 18 to a certain extent. The oil absorption felt two 18 itself is relatively soft, and may be displaced due to factors such as vibration and centrifugal force during the operation of the planetary gear module, affecting its normal oil absorption and lubrication function. The penetration of the T-shaped rod two 20 can position the oil absorption felt two 18 stably in a specific position, so that it can always maintain a relative positional relationship with components such as the planetary gear 4, ensuring the stability of the lubrication effect.

[0030] Working principle: first, when it is necessary to add lubricating oil to the planetary gear, the oil injection groove 5 is opened, the cross slot 8 above the rotating block 6 is rotated to drive the threaded block 9 to rotate, which drives the rubber plug one 10 to be taken out from the oil injection groove 5 along the inner wall of the strip-shaped groove one 16. After taking out, the T-shaped rod one 15 is pulled out, the T-shaped rod one 15 after being pulled out connects the oil absorption felt one 13 and is inserted into the lubricating hole 12 through the oil injection groove 5, then lubricating oil is injected, so that the lubricating oil contacts the oil absorption felt one 13, the oil absorption felt one 13 absorbs and stores the lubricating oil, then the rubber plug two 14 is inserted into the lubricating hole 12 through the T-shaped rod one 15, so that the lubricating hole 12 is sealed. At this time, the top surface of the rubber plug two 14 and the bottom of the inner wall of the arc-shaped channel 11 are located at the same horizontal plane. Lubricating oil is injected into the oil injection groove 5, the lubricating oil flows to the oil absorption felt two 18 through the arc-shaped channel 11, and when the oil absorption felt two 18 absorbs and stores the lubricating oil, the rotating block 6 is rotated in the opposite direction to seal the oil injection groove 5. Finally, the sun gear 2 is started to rotate, driving the planetary gear 4 to rotate, and the planetary gear 4 is extruded when rotating, extruding the oil absorption felt one 13 and the oil absorption felt two 18, and the extruded lubricating oil lubricates the outer wall of the planetary gear 4.

[0031] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
