A dustproof component is installed on the outer wall of the output base, and a detection component is installed on the inner wall of the output base. A fixing sleeve is installed on the outer wall of the output base, and an input shaft is rotatably connected to the inner wall of the fixing sleeve.

Description

Technical Field

[0001] This utility model relates to the field of gear output seat technology, specifically a sealed and dustproof gear output seat. Background Technology

[0002] The sealed dustproof gear output seat uses an integrated, sealed structure to prevent external dust, impurities, and liquid contaminants from entering the gear meshing area. This device typically consists of a high-strength housing, precision-machined bearing seats, wear-resistant seals, and standardized flange / shaft hole interfaces. It not only achieves stable power transmission from the gear set to external equipment, but also extends the service life of the internal grease / lubricating oil through multiple barrier designs, significantly reducing the risk of tooth surface wear, jamming, or corrosion caused by foreign object intrusion. It is widely used in key output parts of reducers, power heads, and other equipment in high-dust environments such as metallurgy, mining, and building materials.

[0003] In existing gear output housing structures, the dustproof structure is prone to aging and deterioration after long-term use, resulting in a decline in sealing performance. External dust can then penetrate the internal cavity of the structure, causing abrasive effects on the gears and interfering with their normal operation. At the same time, if the lubricating oil in the gearbox cavity is not replenished in time and tends to dry out, it will cause direct dry friction between the metal tooth surfaces of the gears, resulting in wear and affecting the stability of gear operation.

[0004] Therefore, a sealed, dustproof gear output seat is needed to improve the above problems. Utility Model Content

[0005] To address the problem that the dustproof structure of a sealed dustproof gear output seat is prone to aging and deterioration after long-term use, resulting in a decline in sealing performance and allowing external dust to enter the internal cavity of the structure, thereby causing the dust to abrade the gears and interfere with their normal operation, this utility model provides a sealed dustproof gear output seat to solve the above-mentioned problems.

[0011] As a preferred embodiment of this utility model, a sliding guide rail is symmetrically arranged on one side of the fixing block and on the outer wall of the positioning base plate.

[0013] As a preferred embodiment of this utility model, the sealed drawer housing is pluggably installed on the side wall of the dustproof housing. A limiting block is installed on one side of the sealed drawer housing and on the outer wall of the dustproof housing, wherein the limiting block limits the sealing drawer housing. A handle is installed on the outer wall of the sealed drawer housing. A drain pipe is installed on the outer wall of the dustproof housing, wherein one end of the drain pipe is located on one side of the filter plate. A lubricating oil pump is installed on the outer wall of the dustproof housing, wherein the outlet of the lubricating oil pump is connected to the outer wall of the dustproof housing via a conduit, and the inlet of the lubricating oil pump is connected to the outer wall of the output base.

[0016] Compared with existing technologies, this utility model achieves the filtration of lubricating oil in a sealed dustproof gear output seat by setting a dustproof component, thereby improving the device's sealing performance. The lubricating oil pump is controlled by a controller to extract lubricating oil from the inner cavity of the output base. The lubricating oil is then discharged into the inner cavity of the dustproof housing. As the lubricating oil passes through the magnetic adsorption column, metal debris in the lubricating oil is magnetically adsorbed. Subsequently, a filter plate adsorbs impurities and dust in the lubricating oil. The lubricating oil is then discharged into the inner cavity of the output base through a drain pipe, further filtering the lubricating oil within the output base. This improves the device's sealing and dustproof effect, thus solving the problem of aging and deterioration of the dustproof structure after long-term use, which leads to a decline in sealing performance and allows external dust to penetrate the internal cavity, causing abrasive effects on the gears and interfering with their normal operation.

[0017] This invention enables the monitoring of lubricating oil in a sealed, dustproof gear output seat by incorporating a detection component. An oil sensor is installed within the output seat's inner cavity. When the lubricating oil level decreases, the sensor generates an electrical signal, which is transmitted to the controller via wires. When the set parameters are reached, the controller activates a warning light, prompting maintenance personnel to add lubricating oil promptly. This addresses the problem of insufficient lubricating oil in the gearbox cavity leading to dryness and direct dry friction between the gear teeth, causing wear and affecting gear stability.

The dustproof housing 201 is installed on the outer wall of the output base 1. A sealed top cover 203 is installed at the port of the dustproof housing 201. Fixed groove blocks 204 are symmetrically arranged on the inner wall of the dustproof housing 201. A filter plate 205 is inserted and removed from the inner wall of the fixed groove block 204. A fixed base plate 206 is installed on the inner wall of the dustproof housing 201. Magnetic adsorption columns 207 are arranged in an array on the base surface of the fixed base plate 206. A positioning block 208 is provided at the top port of the magnetic adsorption column 207. An annular scraper 209 is slidably connected to the outer wall of the magnetic adsorption column 207. A positioning base plate 210 is installed on the bottom outer wall of the annular scraper 209. A fixing block 211 is installed on the opposite outer wall of the positioning base plate 210. A rotating rod 212 is rotatably connected to the outer wall of the fixing block 211.

[0028] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 4 A sliding guide rail 213 is symmetrically arranged on one side of the fixed block 211 and on the outer wall of the positioning base plate 210. A limit block 214 is slidably connected to the inner wall of the sliding guide rail 213. A rotating rod 215 is rotatably connected to the outer wall of the limit block 214. An electric cylinder 216 is installed on the outer wall of the sealing cover 203. Multiple sets of electric cylinders 216 are arranged and are located on the outer wall of the sealing cover 203. A connecting rod 217 is installed at one end of the electric cylinder 216. One end of the connecting rod 217 penetrates the sealing cover 203 and extends into the inner cavity of the dustproof housing 201. The connection between the connecting rod 217 and the sealing cover 203 is a sliding connection. Multiple sets of connecting rods 217 are arranged and are located on the outer wall of the sealing cover 203. One end of each connecting rod 217 is connected to a rotating rod 215. 12 and rotating rod 215, sealed drawer housing 202 is plugged and installed on the side wall of dustproof housing 201, a limiting bottom block 218 is installed on one side of sealed drawer housing 202 and on the outer wall of dustproof housing 201, wherein the limiting bottom block 218 limits the sealed drawer housing 202, a handle 219 is installed on the outer wall of sealed drawer housing 202, a drain pipe 220 is installed on the outer wall of dustproof housing 201, wherein one end of drain pipe 220 is located on one side of filter plate 205, a lubricating oil pump 221 is installed on the outer wall of dustproof housing 201, wherein the outlet of lubricating oil pump 221 is connected to the outer wall of dustproof housing 201 through conduit 222, and the inlet of lubricating oil pump 221 is connected to the outer wall of output base 1, and conduit 222 is located on one side of magnetic adsorption column 207.

[0029] Based on the aforementioned structural features and connection relationships, when the lubricating oil dries up, the lubricating oil in the inner cavity of the dustproof housing 201 decreases, creating a cavity within the dustproof housing 201. Subsequently, the controller 301 controls the electric cylinder 216 to operate, causing one end of the electric cylinder 216 to push the rotating rod 212 and the rotating rod 215 to move via the connecting rod 217. When the rotating rod 212 moves the fixed block 211 upward, the fixed block 211 moves the positioning base plate 210 upward, causing the positioning base plate 210 to drive the annular scraper 209 to scrape off the debris on the surface of the magnetic adsorption column 207, thus removing the debris. The debris accumulates on the surface of the positioning base plate 210. Then, the controller 301 controls one end of the electric cylinder 216 on one side to move down, which causes the electric cylinder 216 to apply a downward force to the rotating rod 215 through the connecting rod 217. This causes the rotating rod 215 to drive the limiting block 214 to move, and then the limiting block 214 to move on the inner wall of the sliding guide rail 213. At the same time, the limiting block 214 applies a downward force to the positioning base plate 210, which causes the positioning base plate 210 to tilt to one side. This causes the debris on the surface of the positioning base plate 210 to slide down into the sealed drawer housing 202 for collection. Then, you can simply open the sealed drawer housing 202 to clean it.

[0030] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The detection component 3 includes a controller 301, a warning light 302, and an oil sensor 303. The controller 301 is installed on the top outer wall of the dustproof housing 201. The warning light 302 is installed on one side of the controller 301 and on the outer wall of the dustproof housing 201. The oil sensor 303 is installed on the inner wall of the output base 1 and is located on one side of the transmission gear 9.

[0031] The controller 301 is electrically connected to the electric cylinder 216, the warning light 302, and the oil sensor 303 via wires, thereby energizing the device and enabling the controller 301 to control the electric cylinder 216, the warning light 302, the lubricating oil pump 221, and the oil sensor 303 to operate.

[0032] When the sealed dustproof gear output seat of this solution is in operation, the switch of the controller 301 is turned on, which in turn causes the controller 301 to control the lubricating oil pump 221 to run. The lubricating oil pump 221 draws out the lubricating oil from the inner cavity of the output base 1, and then the lubricating oil pump 221 discharges the lubricating oil into the inner cavity of the dustproof housing 201. Since the lubricating oil is discharged into the inner cavity of the dustproof housing 201, when the lubricating oil passes through the magnetic adsorption column 207, the metal debris in the lubricating oil is magnetically adsorbed by the magnetic adsorption column 207. Then the filter plate 205 adsorbs the impurities and dust in the lubricating oil. Finally, the lubricating oil is discharged into the inner cavity of the output base 1 through the drain pipe 220, thus filtering the lubricating oil in the inner cavity of the output base 1, so as to make the device have a good sealing and dustproof effect.

[0033] By turning on the switch of controller 301, controller 301 controls the operation of electric cylinder 216, which in turn causes one end of electric cylinder 216 to push rotating rod 212 and rotating rod 215 to move via connecting rod 217. When rotating rod 212 moves fixed block 211 upward, fixed block 211 moves positioning base plate 210 upward, causing positioning base plate 210 to drive annular scraper 209 to scrape off debris from the surface of magnetic adsorption column 207, causing debris to accumulate on the surface of positioning base plate 210. Subsequently, controller 301 controls one end of electric cylinder 216 to move downward, causing electric cylinder 216 to rotate via connecting rod 217. When rod 215 applies a downward pushing force, it causes the rotating rod 215 to move the limiting block 214, which in turn moves on the inner wall of the sliding guide rail 213. At the same time, the limiting block 214 applies a downward pushing force to the positioning base plate 210, causing the positioning base plate 210 to tilt to one side. This causes debris on the surface of the positioning base plate 210 to slide down into the sealed drawer housing 202 for collection. Then, cleaning can be performed simply by opening the sealed drawer housing 202. This solves the problem that the dustproof structure is prone to aging and deterioration after long-term use, resulting in a decline in sealing performance. External dust can then enter the internal cavity of the structure, causing the dust to have an abrasive effect on the gears and interfering with the normal operation of the gears.

[0034] By installing an oil sensor 303 inside the output base 1, when the lubricating oil in the output base 1 decreases, the oil sensor 303 will generate an electrical signal. At the same time, the electrical signal generated by the oil sensor 303 is transmitted to the controller 301 through the wire. When the set parameters are reached, the controller 301 will control the warning light 302 to operate, thereby prompting maintenance personnel to add lubricating oil in time. This solves the problem that if the lubricating oil in the gearbox cavity is not replenished in time and tends to dry out, it will cause direct dry friction between the metal tooth surfaces of the gears, resulting in wear and affecting the stability of gear operation.

[0035] The electrically controlled cylinder 216, warning light 302, oil sensor 303, lubricating oil pump 221, and controller 301 used in this utility model are all existing known electrical devices, and all can be purchased and used directly on the market. Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the electrically controlled cylinder 216, warning light 302, lubricating oil pump 221, oil sensor 303, and controller 301 will not be described in detail here.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.
