Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a reducer gear set. Background Art

[0002] The reducer gear set refers to the components that need to be lubricated, such as reducers, gears, rolling bearings, etc., and there are also some other components. Improving the lubrication efficiency of these components can improve the safety of production and increase the life of the equipment, reduce labor intensity, and improve the economic benefits of the enterprise. For example, the publication number "CN116557504A" proposes a compact reduction gearbox, including: a box shell, the box shell includes a first shell and a second shell connected together, the first shell is provided with a rotatable input shaft, and the second shell is provided with a rotatable first output shaft; a multi-stage reduction transmission assembly, which is distributed in the first shell and the second shell, and the input shaft is connected to the first output shaft. In the present invention, the multi-stage reduction transmission assembly is installed in the cavity formed by the first shell and the second shell, and the input shaft is connected to the first output shaft. The first shell and the second shell are detachably connected front and back. The overall structure is simpler and more compact, and it is easy to maintain. After the speed of the input shaft is multi-stage reduced by the multi-stage reduction transmission assembly, the first output shaft is controlled to rotate slowly. This graded reduction method can reduce the volume of the overall structure.

[0003] However, in the above technical solution, when lubricating the internal gear set of the above-mentioned gear reducer, although the first housing and the second housing can be disassembled to lubricate the internal gears, frequent disassembly of the gear box may cause dust in the outside air to be adsorbed on the gear surface, increasing the friction coefficient of the gear, causing the gear to generate greater heat and wear during operation, thereby reducing the transmission efficiency and service life of the gear. Utility Model Content

[0004] The main purpose of the utility model is to provide a reducer gear set, which can effectively solve the problem that when lubricating the internal gear set of the gear reducer in the background technology, although the first shell and the second shell can be disassembled to lubricate the internal gears, the frequent disassembly of the gear box may cause dust in the outside air to be adsorbed on the gear surface, increasing the friction coefficient of the gear, causing the gear to generate greater heat and wear during operation, thereby reducing the transmission efficiency and service life of the gear.

[0026] Support plates 6 are fixedly installed on both sides of the top of the gear box 1 , a storage box 9 is arranged between the two support plates 6 , and a dropper 10 is fixedly installed on the lower surface of the storage box 9 .

[0027] A threaded rod 7 is rotatably mounted on the opposite side, a top plate 8 is threadedly arranged on one side of the rod body of the threaded rod 7, and the lower surface of the top plate 8 is fixedly connected to the storage box 9;

[0028] A first motor 11 is fixedly mounted on one side of one of the support plates 6 away from the top plate 8 , and one end of the threaded rod 7 passes through the support plate 6 and is fixedly connected to the output shaft end of the first motor 11 .

[0029] A positioning rod 12 is fixedly installed between the two support plates 6 , and the top plate 8 is slidably arranged on one side of the rod body of the positioning rod 12 .

[0030] The staff connects the shaft end of the driving device with the input shaft 2, and then connects the shaft end of the output device with the output shaft 4, to achieve a deceleration function under the cooperation of the first gear 3 and the second gear 5. When the first gear 3 and the second gear 5 need to be lubricated, the staff starts the first motor 11 to make its output shaft end drive the threaded rod 7 to rotate, and the rotating threaded rod 7 drives the top plate 8 to move along the positioning rod 12 by screwing in the thread, so that the storage box 9 and the dropper 10 move along the direction of the positioning rod 12, so that the lubricant in the storage box 9 drops through the dropper 10 to the meshing position of the first gear 3 and the second gear 5, so that the staff can lubricate the first gear 3 and the second gear 5 without disassembling the gear box 1. There is no need for the staff to frequently disassemble the gear box 1 for lubrication, which prevents dust in the outside air from being adsorbed on the gear surface, ensuring that the transmission efficiency and service life of the gear are not affected.

[0035] In another embodiment of the utility model, a support groove 18 is penetrated through the bottom surface of the gear box 1, a slide groove 19 is penetrated through one side of the inner wall of the support groove 18, a recovery box 20 is slidably arranged in the slide groove 19, and a handle 21 is fixedly installed on one side of the recovery box 20.

[0036] The lubricant dropped from the gap between the first gear 3 and the second gear 5 enters the recovery box 20, and then the staff pulls the handle 21 to move the recovery box 20 along the slide 19, so that the recovery box 20 moves to the outside of the storage box 9, so that the staff can recycle and reuse the dripping lubricant.

[0037] In another embodiment of the present invention, a through slot 22 is formed through the top surface of the gear box 1 , and an observation window 23 is fixedly installed inside the through slot 22 .

[0038] The observation window 23 is provided to facilitate the staff to observe the lubrication progress of the first gear 3 and the second gear 5 inside the gear box 1 .

[0039] The working principle of this kind of reducer gear set:

[0040] When in use, the staff connects the shaft end of the driving device with the input shaft 2, and then connects the shaft end of the output device with the output shaft 4, and realizes the deceleration function under the cooperation of the first gear 3 and the second gear 5. When the first gear 3 and the second gear 5 need to be lubricated, the staff starts the first motor 11 to make its output shaft end drive the threaded rod 7 to rotate, and the rotating threaded rod 7 drives the top plate 8 to move along the positioning rod 12 by screwing in the thread, so that the storage box 9 and the dropper 10 move along the direction of the positioning rod 12, so that the lubricant in the storage box 9 drops through the dropper 10 to the meshing point of the first gear 3 and the second gear 5, so that the staff can lubricate the first gear 3 and the second gear 5 without disassembling the gear box 1, and the staff does not need to frequently disassemble the gear box 1 for lubrication, which prevents dust in the outside air from being adsorbed on the gear surface, ensuring that the transmission efficiency and service life of the gear are not affected.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention.
