Description

Technical Field

[0001] This utility model belongs to the technical field of gear reducers, specifically relating to a gear reducer that can provide uniform and sufficient lubrication. Background Technology

[0002] A gear reducer is a mechanical device that uses multiple gears to reduce speed. It achieves this by using a small gear to drive a large gear, and is typically supplied as a complete set by specialized gear reducer manufacturers. Gear reducers are widely used in various mechanical equipment to improve production efficiency, reduce energy consumption, and ensure stable equipment operation.

[0003] When using a gear reducer, lubricating oil needs to be added for lubrication to reduce wear between gears and reduce temperature. To achieve circulating lubrication, a circulating oil supply device is generally installed. For example, Chinese patent document CN219994351U discloses a gear reducer with a lubrication function, which uses a suction pump to circulate the lubricating oil in the gearbox and filters impurities in the lubricating oil through a filter screen.

[0004] However, the above technical solutions have the following drawbacks: 1. Impurities will be generated during the circulating filtration process. Since the filter components are generally located inside the reducer housing, they are not easy to clean. 2. Since the reduction gear set inside the reducer housing generally covers a large area, it is difficult to spray lubrication evenly. Utility Model Content

When the filter needs to be cleaned, the screws can be opened, the cover plate can be removed, and the retainer and filter can be taken out for cleaning. At the same time, the screws can be unscrewed to open the top cover plate and clean the flow divider plate. The lubricating oil enters the gap cavity and is then sprayed out through the flow divider hole under pressure to uniformly spray the reduction gear assembly below, thereby solving the problems mentioned in the background art.

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.

[0023] Please see Figure 1-5 This utility model provides a gear reducer that can provide uniform and sufficient lubrication, including a reducer housing 1, on which a reduction gear assembly 2 is mounted; the inner cavity of the reducer housing 1 has a funnel-shaped collection groove 3 at the bottom, and a filter assembly is mounted at the bottom of the reducer housing 1, with one end of the filter assembly extending to the bottom of the collection groove 3; an oil pump 4 is mounted on the outside of the reducer housing 1, and the oil pump 4 is connected to the filter assembly via a hose 5; the oil pump 4 is connected to the top of the reducer housing 1 via the hose 5, and a diversion mechanism is mounted on the top of the reducer housing 1; in use, the reduction gear assembly 2 is driven by a power motor and an actuator for speed reduction transmission. During this process, sufficient lubricating oil is added to the reducer housing 1, and the lubricating oil is collected at the bottom of the collection groove 3. After the oil pump 4 is started, a negative pressure suction is generated in the mounting groove through the hose 5, which draws the lubricating oil at the bottom of the collection groove 3 through the filter 6 and into the top gap cavity through the hose 5, and then diverts and sprays it out to the reduction gear assembly 2 below for uniform spraying.

[0024] Specifically, the filter assembly includes a filter 6 and a retainer 7. The reducer housing 1 has a mounting groove on one side of its bottom. A filter groove is provided between the mounting groove and the collection groove 3. The filter 6 is installed in the filter groove, with its head extending into the collection groove 3. The filter 6 has a blocking edge 8. The retainer 7 is installed in the mounting groove and abuts against the blocking edge 8. A cover plate 9 is fixed to the outside of the reducer housing 1 by screws. In this embodiment, after the oil pump 4 is started, a negative pressure suction is generated in the mounting groove covered by the cover plate 9 through the hose 5, which will filter the lubricating oil at the bottom of the collection groove 3 through the filter 6. When it is necessary to clean the filter 6, the screws are opened, the cover plate 9 is removed, and then the retainer 7 and the filter 6 are taken out for cleaning.

[0025] Specifically, the retainer 7 is a silicone sealing ring; in this embodiment, the silicone sealing ring is designed to work with the blocking edge 8 to position the filter 6 without interfering with the flow of lubricating oil.

[0026] Specifically, the filter 6 has a central cavity 10, one end of which is closed and the other end is open when it extends into the collection tank 3. The outer wall of the end of the filter 6 that extends into the collection tank 3 has a filter hole 11. In this embodiment, after the oil pump 4 is started, the negative pressure suction force is generated in the mounting groove covered by the cover plate 9 through the hose 5, which will draw the lubricating oil at the bottom of the collection tank 3 into the central cavity 10 through the filter hole 11 of the filter 6, and then into the retainer 7, and then into the top gap cavity through the hose 5.

[0027] Specifically, the diversion mechanism includes a mounting groove on the top of the reducer housing 1, in which a diversion plate 12 is installed. A top cover plate 13 is fixed to the top of the reducer housing 1 by screws. There is a gap cavity between the top cover plate 13 and the diversion plate 12. The oil pump 4 is connected to the top cover plate 13 through the hose 5. In this embodiment, the lubricating oil is drawn into the central cavity 10 through the filter hole 11 of the filter 6, then enters the retainer 7, and then enters the gap cavity between the top cover plate 13, the diversion plate 12, and the second retainer 14 through the hose 5, and then is diverted and sprayed.

[0028] Specifically, the flow divider 12 and the top cover plate 13 are fixed together by a second retainer 14, which is a silicone sealing ring. In this embodiment, the silicone sealing ring is designed to cooperate with the top cover plate 13 to position the flow divider 12 without interfering with the flow of lubricating oil.

[0029] Specifically, the diverter plate 12 has uniformly arranged diverter holes 15 on the top of the corresponding reduction gear assembly 2; in this embodiment, lubricating oil enters the gap cavity and is then sprayed out through the diverter holes 15 under pressure to uniformly spray the reduction gear assembly 2 below.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] Working principle: During use, the reduction gear assembly 2 reduces speed by connecting the power motor and the actuator. During this process, sufficient lubricating oil is added to the reducer housing 1. The lubricating oil is collected at the bottom through the collection tank 3. After the oil pump 4 is started, a negative pressure suction is generated in the mounting groove covered by the cover plate 9 through the hose 5. The lubricating oil at the bottom of the collection tank 3 is sucked into the central cavity 10 through the filter hole 11 of the filter 6, and then enters the retainer 7. It then enters the gap cavity between the top cover plate 13, the diverter plate 12, and the second retainer 14 through the hose 5. Under pressure, it is sprayed out through the diverter flow hole 15 to spray the reduction gear assembly 2 below evenly. When the filter 6 needs to be cleaned, the screws are loosened, the cover plate 9 is removed, and the retainer 7 and filter 6 are taken out for cleaning. At the same time, the screws are loosened to open the top cover plate 13 and clean the diverter plate 12.
