Description

Technical Field

[0001] The utility model relates to the technical field of speed reducers, in particular to a gear lubrication device for a right-angle speed reducer. Background Technique

[0002] A right-angle speed reducer, also known as a worm and worm gear speed reducer, is a speed reducer based on gear transmission. The internal gear device is the core component of the right-angle speed reducer. The power transmission and speed reduction are achieved through the meshing of the worm gear and the worm. In order to extend the service life of the gears in the right-angle speed reducer, a lubrication device is required to lubricate the gears. However, the existing gear lubrication devices still have certain deficiencies in use.

[0003] For example, a gear lubrication device for a speed reducer with the publication number of CN211398519U. By pouring lubricating oil into the lubrication box, the bottom of the lubricating gear is in contact with the lubricating oil. The speed reducer gear is driven to rotate through the handle, connecting rod, connecting plate and several support rods. Through the meshing connection between the speed reducer gear and the lubricating gear, it is convenient to evenly apply the lubricating oil wrapped on the outer wall of the lubricating gear on the teeth of the speed reducer gear, so that the deep part of the tooth groove of the speed reducer gear can contact the lubricating oil. And through the gear hole, it is convenient to take out the speed reducer gear coated with lubricating oil. The operation is simple and the coating is convenient, with good practicability and popularization. However, during the coating process, manually operating to apply lubricating oil takes a long time, reducing work efficiency. And the specifications of different gears are different, and it cannot adapt to gears with different hole diameters, restricting its versatility and flexibility. At the same time, if the module numbers of two gears are inconsistent, their tooth pitches will be different, resulting in incorrect meshing. During the transmission process, the lubricating oil may be contaminated by metal chips, impurities, etc. These contaminants may be carried to the upper-layer gears along with the lubricating oil, exacerbating the wear and damage of the gears.

[0004] Therefore, we propose a gear lubrication device for a right-angle speed reducer to solve the problems raised above. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] Embodiment 1: Please refer to Figures 1 - 4 As shown, the present invention provides a technical solution: a gear lubrication device for a right-angle reducer, including a device body 1, a driving motor 2 is fixedly connected inside the device body 1, and a rotating shaft 3 is fixedly connected to the output end of the driving motor 2. A lubricating oil tank 18 is fixedly connected inside the device body 1 on the side of the driving motor 2, and a pneumatic oil pump 19 is fixedly connected to the upper end of the lubricating oil tank 18.

[0026] This technical solution utilizes the settings of the driving motor 2 and the pneumatic oil pump 19. When in use, first place the device on a flat and open ground, then prepare the gear to be lubricated and place it inside the device body 1. Start the driving motor 2 and the pneumatic oil pump 19. The driving motor 2 will drive the gear to be lubricated to rotate, and the pneumatic oil pump 19 will pressurize the lubricating oil tank 18 with gas, so that the lubricating oil in the lubricating oil tank 18 flows out through the pipeline and is evenly applied to the surface of the gear. After the lubrication operation is completed, it can be taken off.

[0027] Embodiment 2: The technical content disclosed in this embodiment is an improvement based on Embodiment 1 above. In the existing process of smearing, manual operation of smearing lubricating oil takes a long time, reducing work efficiency. Moreover, the specifications of different gears are different, and it is impossible to adapt to gears with different apertures, restricting its versatility and flexibility. This technical solution is as Figure 1 and Figure 2As shown in the figure, a clamping assembly of a lubricating device is disclosed. A driving gear 4 is sleeved outside a rotating shaft 3. The top end of the rotating shaft 3 is fixedly connected with a fan 5. A box body 6 is fixedly connected to the inner wall of the device body 1 outside the fan 5. An auxiliary gear 7 that cooperates with the driving gear 4 is rotatably connected in the device body 1. A shaft rod 8 is fixedly connected inside the auxiliary gear 7. One end of the shaft rod 8 away from the auxiliary gear 7 is fixedly connected with a fixing block 9. A telescopic rod 13 is arranged in the middle of the fixing block 9. A straight groove 901 is formed in the fixing block 9. One end of the telescopic rod 13 penetrates into the fixing block 9 and is connected with a clamping mechanism. The driving gear 4 meshes with the auxiliary gear 7, and the diameter of the driving gear 4 is smaller than that of the auxiliary gear 7. The telescopic rod 13 is in threaded rotation connection with the fixing block 9. Four straight grooves 901 on the fixing block 9 are arranged in a circular array around the center point of the fixing block 9. The clamping mechanism includes a disc 10, a slider 11 and a clamping plate 12. The disc 10 is rotatably arranged in the fixing block 9 and is fixedly connected with the telescopic rod 13. A guide groove 1001 is formed in the disc 10. The slider 11 is slidably arranged in the straight groove 901. One end of the slider 11 is fixedly connected with the clamping plate 12. The end of the slider 11 away from the clamping plate 12 penetrates into the guide groove 1001. The guide groove 1001 is arranged in an arc structure. Four guide grooves 1001 and sliders 11 are arranged in a circular array around the center point of the disc 10, and the guide grooves 1001 and sliders 11 correspond to the straight grooves 901 one by one.

[0028] In the technical solution, as Figure 1 shown, by means of the arrangement of the guide groove 1001 and the straight groove 901, when the disc 10 rotates, the slider 11 will drive the clamping plate 12 to slide up and down along the guide groove 1001 and the straight groove 901, so as to clamp gears of different specifications. The structure is simple, can automatically adapt to gears of different specifications, and improves the working efficiency and clamping accuracy.

[0029] It adopts the technical solution as Figure 2 shown. First, place the gear to be lubricated on the fixing block 9 and rotate the telescopic rod 13. Since the telescopic rod 13 is in threaded connection with the fixing block 9, the telescopic rod 13 will rotate into the inside of the fixing block 9, and the telescopic rod 13 will drive the disc 10 to rotate, so that the slider 11 slides along the guide groove 1001 and the straight groove 901. Under the guidance of the straight groove 901, the slider 11 will drive the clamping plate 12 to move outwards, so as to fit with the inner wall of the gear and perform limit clamping on it. Then, turn on the driving motor 2. The driving motor 2 will drive the rotating shaft 3 to rotate. Then, the rotating shaft 3 will drive the driving gear 4 to rotate, so that the driving gear 4 meshes with the auxiliary gear 7, thereby driving the auxiliary gear 7 to rotate. Since the driving gear 4 is smaller than the auxiliary gear 7, the number of rotations of the driving gear 4 is greater than that of the auxiliary gear 7, and then drive the gear on the fixing block 9 to rotate slowly, ensuring that the lubricating oil can be evenly applied to the surface of the gear.

[0030] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1 and Embodiment 2. When the module numbers of two gears are inconsistent, their pitch will be different, resulting in incorrect meshing. During the transmission process, the lubricating oil may be contaminated by metal chips, impurities, etc. These contaminants may be carried to the upper gears along with the lubricating oil, exacerbating the wear and damage of the gears. To further solve this technical problem, the technical solution is as follows Figure 3 and Figure 4 shown. The impurity removal component of the lubricating device is disclosed. A rectangular block 14 is fixedly connected inside the device body 1 below the clamping mechanism. A rectangular groove 15 is formed in the rectangular block 14, and a threaded rod 16 is rotatably connected inside the rectangular groove 15. A set of moving parts 17 is sleeved outside the threaded rod 16. A blowing nozzle 20 is arranged on one of the moving parts 17, and a brush 21 is arranged on the other moving part 17. The threaded rod 16 is a double-threaded screw rod, and the threaded rod 16 is threadedly connected to the two moving parts 17. Both moving parts 17 are slidably connected to the rectangular groove 15, and the thread directions of the two moving parts 17 on the threaded rod 16 are opposite. The blowing nozzle 20 on the moving part 17 is inclined, and the blowing nozzle 20 is communicated with the box body 6 through a hose. The other moving part 17 is fixedly connected to the brush 21, and the brush 21 is communicated with the oil outlet end of the lubricating oil tank 18 through a hose. And the lubricating oil tank 18 is communicated with the air inlet end of the pneumatic oil pump 19.

[0031] In this technical solution, as Figure 3 shown, by setting the fan 5, when the rotating shaft 3 rotates, it will drive the fan 5 to rotate synchronously, thereby forming an air flow, and blowing the air flow into the blowing nozzle 20 and spraying it out from the blowing nozzle 20. The sprayed gas will blow off the impurities attached to the gear surface, realizing the automatic cleaning of the gear surface, thereby significantly improving the lubrication effect and reducing friction and wear.

[0032] It adopts the technical solution as Figure 4 shown. First, rotate the threaded rod 16 so that the threaded rod 16 meshes with the two moving parts 17, thereby driving the two moving parts 17 to slide close to or away from each other along the rectangular groove 15, and then adjusting the positions of the blowing nozzle 20 and the brush 21 to ensure that the blowing nozzle 20 is aligned with the surface of the gear to be lubricated, and the brush 21 is in contact with the gear. Immediately afterwards, when the rotating shaft 3 rotates, it will drive the fan 5 to rotate. The air flow generated by the rotation of the fan 5 is transported to the blowing nozzle 20 through a pipeline and then sprayed onto the surface of the gear by the blowing nozzle 20, thereby blowing off the impurities attached to the gear surface. Immediately afterwards, the pneumatic oil pump 19 will apply pressure to the lubricating oil tank 18, so that the lubricating oil flows into the brush 21 through a pipeline. Since the brush 21 is in contact with the gear, the lubricating oil can be evenly applied to the surface of the gear. After the application is completed, it can be removed.

[0033] The content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0034] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
