Description

Technical Field

[0002] Gear reducer motors use an electric motor as a power source to drive gear reducers and control the deceleration of working equipment. Gear reduction works by controlling the gear reducer motor through different gears, and while reducing speed, it amplifies torque to meet the load requirements. However, during use, it is easy to generate debris, which can damage the gear reducer and affect the service life of the equipment.

During the operation of the device, through the action of the protrusion, mounting rod, ball and spring, the brush plate can move up and down in an orderly manner while rotating, thereby ensuring the cleaning effect of the brush plate on the driven wheel and effectively avoiding wear debris from increasing friction and affecting the service life of the device. Although the existing technology can complete quantitative feeding, if the lubricating oil is not added or replaced in time during operation, it is very easy to damage the gear reduction mechanism, affecting the safety and service life. Moreover, the lubricating oil is generally added manually, which affects the normal operation of the gear reduction equipment, and the slow replacement can easily cause leakage.

[0024] 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.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a novel low-wear gear reduction motor, comprising a drive motor 1 for driving operation, wherein an output shaft 2 is rotatably connected to the central shaft of the drive motor 1, and a reduction gear set 3 is assembled at the end of the output shaft 2 via a coupling.

[0026] Example 1: As Figures 1-4The technical solution shown is provided by this utility model as follows: A novel low-wear gear reduction motor is disclosed, comprising: a first bevel gear 4, mounted on the outer surface of an output shaft 2, with a second bevel gear 5 meshing with the front side of the outer surface of the first bevel gear 4; a splined shaft 6 is slidably connected to the central shaft of the second bevel gear 5; a moving component 7 is rotatably connected to the outer surface of the splined shaft 6; and the moving component 7 is provided with a moving docking mechanism; the second bevel gear 5 forms a meshing rotation structure with the output shaft 2 through the first bevel gear 4, and the second bevel gear 5 forms a meshing rotation structure with the moving component 7 through the splined shaft 6. The moving assembly 7 has a positioning and rotating structure, and the second bevel gear 5 and the spline shaft 6 form a nested sliding structure. The moving docking mechanism includes a telescopic assembly 10 installed on the inner surface of the moving assembly 7, and a telescopic rod 9 is telescopically connected to the inner surface of the telescopic assembly 10. A nested ring 8 is installed on the outer surface of the telescopic rod 9, and the side of the nested ring 8 is slidably connected to the inner surface of the moving assembly 7. At the same time, the second bevel gear 5 is nested and rotatably connected to the rear side of the outer surface of the nested ring 8. The moving assembly 7 forms a limiting telescopic structure with the nested ring 8 through the telescopic assembly 10 and the telescopic rod 9, and the nested ring 8 and the second bevel gear 5 form a nested rotating structure.

[0027] When lubricating oil needs to be added to the reduction gear set 3, it will be added at regular intervals using a timer. When it is time to replace it, the telescopic component 10 built into the moving component 7 can be activated to adjust the telescopic rod 9 to unfold it. The telescopic rod 9 drives the installed nested ring 8 to approach the output shaft 2, and drives the second bevel gear 5 connected to the nested ring 8 to mesh with the first bevel gear 4 on the output shaft 2. The output shaft 2 rotates stably under the drive of the drive motor 1, which can stably control the spline shaft 6 assembled with the second bevel gear 5 to rotate, and drive the third bevel gear 11 assembled on the rear side of the spline shaft 6 to rotate.

[0028] Example 2: Figures 1-4The technical solution shown, based on Embodiment 1, further discloses an oil delivery assembly 13 for extruding and delivering lubricating oil. The specific details are as follows: a telescopic assembly 10 is rotatably connected to a third bevel gear 11 via a splined shaft 6, and a fourth bevel gear 12 is meshed with the lower surface of the third bevel gear 11. The oil delivery assembly 13 is nested and rotated on the outer surface of the fourth bevel gear 12. Simultaneously, a threaded rod 14 is slidably connected to the outer surface of the oil delivery assembly 13, and the threaded rod 14 is threaded onto the inner surface of the fourth bevel gear 12. An extrusion plate 1 is mounted on the lower surface of the threaded rod 14. 5. The extrusion plate 15 is nested on the inner surface of the oil delivery assembly 13. The telescopic assembly 10 forms a rotating structure with the third bevel gear 11 through the spline shaft 6. The third bevel gear 11 and the second bevel gear 5 form a coaxial rotating structure. The third bevel gear 11 and the fourth bevel gear 12 form a meshing structure. At the same time, the fourth bevel gear 12 and the oil delivery assembly 13 form a nested rotation. The fourth bevel gear 12 and the threaded rod 14 form a threaded structure. The threaded rod 14 and the oil delivery assembly 13 form a limiting lifting structure. At the same time, the threaded rod 14 and the extrusion plate 15 form an integrated structure.

[0029] When the third bevel gear 11 rotates, the meshing adjustment fourth bevel gear 12 is nested and rotated on the upper side of the oil delivery assembly 13. This allows the threaded adjustment rod 14 of the fourth bevel gear 12 to be threaded and controlled. Under the limit of the oil delivery assembly 13, the threaded rod 14 is adjusted to descend vertically, and the extrusion plate 15 installed on the threaded rod 14 is driven to extrude the lubricating oil and deliver the lubricating oil to the reduction gear set 3 for adding or replacing.

[0030] Example 3: Figure 1 , Figure 2 , Figure 5 and Figure 6The technical solution shown, based on Embodiment 2, further discloses the assembly and replacement of the oil storage tank 16, the specific details of which are as follows: The oil storage tank 16 is nested and connected to the inner surface of the oil delivery assembly 13 on which the movable assembly 7 is installed, and the oil delivery assembly 13 is provided with a limit locking mechanism; the limit locking mechanism includes a locking block 17 slidably connected to the inner surface of the oil delivery assembly 13, and a return spring 18 elastically connected between the locking block 17 and the oil delivery assembly 13, and a compression block 19 is installed on the rear side of the outer surface of the locking block 17, while a compression block 20 is obliquely compressed and connected to the upper side of the outer surface of the compression block 19, and a connecting rod 21 is installed on the outer surface of the compression block 20, and the connecting rod 21 is connected to... A compression spring 22 is elastically connected between the oil delivery components 13. At the same time, a one-way valve 23 is installed on the lower side of the inner surface of the oil storage tank 16, and an oil delivery pipe 24 is connected to the lower surface of the one-way valve 23. The two ends of the oil delivery pipe 24 are respectively installed on the sides of the reduction gear set 3 and the oil delivery component 13. The oil delivery component 13 forms an elastic limiting engagement structure with the oil storage tank 16 through the return spring 18 and the locking block 17. The locking block 17 forms a compression structure with the connecting rod 21 through the compression block one 19 and the compression block two 20. The connecting rod 21 forms an elastic sliding structure with the oil delivery component 13 through the compression spring 22. At the same time, the oil delivery component 13 forms a linkage structure with the reduction gear set 3 through the oil delivery pipe 24.

[0031] When the oil delivery assembly 13 controls the extrusion plate 15 to extrude oil into the oil storage tank 16, the lubricating oil inside the oil storage tank 16 is stably delivered to the reduction gear set 3 through the use of the one-way valve 23 and the oil delivery pipe 24. After a set of oil storage tanks 16 containing a large amount of lubricating oil is used up, the extrusion plate 15 is driven to retract to the top of the inner surface of the oil delivery assembly 13, and the control linkage 21 drives the second extrusion block 20 to move down, extruding the first extrusion block 19 connected to the second extrusion block 20 at an angle, and controlling the locking block 17 installed on the first extrusion block 19 to disengage. The oil reservoir 16 is limited, and the oil reservoir 16 is removed and replaced with another set of oil reservoirs 16 with a large amount of lubrication. After the new oil reservoir 16 is placed, the connecting rod 21 is loosened, and the compression spring 22 between the connecting rod 21 and the oil delivery assembly 13 will control it to move upward and reset. The compression block 20 is released from the compression of the compression block 19. By using the reset spring 18, the locking block 17 is controlled to limit the oil reservoir 16 for subsequent lubrication addition work and to increase the low wear effect of the gear reduction motor.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
