Abstract
Description
Technical Field
[0001] This utility model relates to the field of lubrication device technology, and in particular to a speed reducer lubrication device. Background Technology
[0002] A speed reducer is a mechanical transmission device mainly used to reduce the input speed and correspondingly increase the output torque to meet the specific requirements of different mechanical equipment for power transmission. The speed reducer transmits power through an internal gear device or chain drive device, and converts the high-speed rotation of the input shaft into the low-speed, high-torque rotation of the output shaft according to the designed reduction ratio.
[0003] During use, speed reducers need to be lubricated regularly. Lubricating oil is sprayed directly onto the gear meshing points through nozzles. However, the internal gear set structure of the speed reducer is complex, with too many gear meshing points. It is difficult for the nozzles to spray the lubricating oil evenly onto the gear meshing points. In addition, traditional speed reducer lubrication devices cannot circulate the lubricating oil, resulting in waste. Utility Model Content

[0021] 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.
[0022] This utility model provides, for example Figures 1-4 The illustrated gear reducer lubrication device includes a gear reducer body 1, an oil collection tank 3, and a reciprocating drive mechanism. A nozzle 18 is installed on top of the gear reducer body 1, which is used to spray lubricating oil into the interior of the gear reducer body 1. The oil collection tank 3 is fixedly connected to the bottom of the gear reducer body 1, and a pipe 6 is fixedly connected to the lower side of the outer wall of the oil collection tank 3. One end of the pipe 6 away from the oil collection tank 3 is fixedly connected to the top of the nozzle 18, and an oil pump 8 is fixedly connected to the middle of the pipe 6. The reciprocating drive mechanism is installed on top of the gear reducer body 1 and is used to drive the nozzle 18 to move back and forth. The nozzle 18 sprays lubricating oil into the interior of the gear reducer body 1. The reciprocating drive mechanism drives the nozzle 18 to move back and forth above the gear reducer body 1, increasing the spray range of the nozzle. The lubricating oil wets the gear meshing area, and the oil collection tank 3 recovers the excess lubricating oil, making the lubricating oil reusable and saving lubricating oil costs.
[0023] On one hand, a housing 7 is fixedly connected to the top of the reducer body 1, an oil pump 8 is fixedly connected to the outer wall of the housing 7, a base 2 is fixedly connected to the bottom of the oil collection tank 3, and a support rod 11 is fixedly connected between the base 2 and the housing 7. The support rod 11 assists in supporting the housing 7. When it is necessary to lubricate the internal structure of the reducer body 1, the oil pump 8 is started, the oil pump 8 draws out the lubricating oil inside the oil collection tank 3, and then sprays the lubricating oil from the nozzle 18 to complete the lubricating oil spraying work.
[0024] On the other hand, the reciprocating drive mechanism includes a slider 17, a housing 7 fixedly connected to the outer wall of the reducer body 1, a groove 16 opened at the bottom of the inner cavity of the housing 7, the outer wall of the slider 17 slidingly connected to the inner wall of the groove 16, and the slider 17 fixedly sleeved on the outer wall of the nozzle 18. A drive component 9 is fixedly connected to the top of the housing 7, the drive component 9 can be a motor, a rotating shaft 19 is rotatably connected to the top of the inner cavity of the housing 7, the drive component 9 is used to drive the rotating shaft 19 to rotate, an eccentric wheel 10 is fixedly connected to the bottom of the rotating shaft 19, a first connecting rod 14 is rotatably connected to the side of the eccentric wheel 10 opposite to the rotating shaft 19, and a second connecting rod 15 is fixedly connected to the outer wall of the slider 17. The end of the first connecting rod 14 is rotatably connected to the end of the second connecting rod 15. The eccentric wheel 10 is driven to rotate by the driving component 9. The eccentric wheel 10 drives the second connecting rod 15 to move through the first connecting rod 14. The second connecting rod 15 drives the slider 17 to move. The slider 17 can only move horizontally along the inner wall of the slide groove 16 under the limit of the slide groove 16. The eccentric wheel 10 continues to rotate, driving the second connecting rod 15 and the slider 17 to move horizontally back and forth. The slider 17 drives the nozzle 18 to move back and forth above the reducer body 1. The nozzle 18 can spray lubricating oil to the meshing points of different gears in the reducer body 1, thereby increasing the spray range of the nozzle 18.
[0025] Preferably, a circular tube 12 is fixedly connected to the bottom of the reducer body 1, and a filter screen 13 is fixedly connected to the inner wall of the circular tube 12. After the lubricating oil wets the gear meshing part inside the reducer body 1, the excess lubricating oil flows down from the surface of the gear set and drips to the bottom of the inner cavity of the reducer body 1. The excess lubricating oil flows into the oil collection tank 3 from the circular tube 12. At the same time, the filter screen 13 inside the circular tube 12 filters out the impurities mixed in with the lubricating oil inside the reducer body 1, preventing impurities from contaminating the lubricating oil and extending the service life of the lubricating oil cycle.
[0026] In addition, an oil change pipe 4 is fixedly connected to the outer wall of the oil collection tank 3. An end cap 5 is threadedly connected to the outer wall of the oil change pipe 4. After the lubricating oil has been used multiple times, the worker can open the end cap 5, insert the oil suction pipe through the oil change pipe 4 into the oil collection tank 3, start the oil suction equipment to extract the old lubricating oil in the oil collection tank 3, and after the oil suction work is completed, the new lubricating oil is pumped into the oil collection tank 3. After screwing on the end cap 5, the oil change work is completed.
[0027] In specific operation: When lubrication of the internal structure of the reducer body 1 is required, the oil pump 8 is started. The oil pump 8 draws out the lubricating oil from the oil collection tank 3 and then sprays the lubricating oil from the nozzle 18 to complete the lubrication work. The drive component 9 drives the eccentric wheel 10 to rotate. The eccentric wheel 10 drives the second connecting rod 15 to move through the first connecting rod 14. The second connecting rod 15 drives the slider 17 to move. The continuous rotation of the eccentric wheel 10 drives the second connecting rod 15 and the slider 17 to move back and forth horizontally. The slider 17 drives the nozzle 18 to move on the reducer. The nozzle 18 reciprocates above the main body 1, spraying lubricating oil onto different gear meshing points of the reducer body 1, thereby increasing the spray range of the nozzle 18. Excess lubricating oil flows into the oil collection tank 3 through the circular pipe 12. At the same time, the filter screen 13 inside the circular pipe 12 filters out impurities mixed into the lubricating oil inside the reducer body 1, preventing impurities from contaminating the lubricating oil. After the lubricating oil has been used multiple times, the worker can open the end cover 5, insert the oil extraction pipe through the oil replacement pipe 4 into the oil collection tank 3, and start the oil extraction equipment to extract the old lubricating oil from the oil collection tank 3.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
