Description

Technical Field

[0001] The invention relates to the technical field of reducers, and in particular to an oil leakage-proof vertical reducer. Background Art

[0002] The reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator. It is widely used in modern machinery. At the same time, there are many types of reducers, such as some vertical reducers, planetary reducers, etc.

[0003] According to publication number CN202110533793.3, a strong and stable mobile industrial robot reducer includes a motor housing, a junction box and a connecting flange. The junction box is fixedly connected to the upper right side of the motor housing, the left side of the motor housing is fixedly connected to the connecting flange, the left side of the connecting flange is fixedly connected to the reducer housing, a lifting ring is fixedly connected to the upper left side of the reducer housing, a refueling hole is fixedly connected to the upper right side of the reducer housing, and an output shaft is fixedly connected to the middle of the front of the reducer housing. The present invention overcomes the shortcomings of the prior art. When the robot reducer rotates through the helical teeth in the reducer housing, the high-speed reducer can dissipate heat from the output shaft passing through the keyway and the shaft hole through the heat dissipation holes, and then the oil seal seals the output shaft in the keyway and the shaft hole. This can prevent oil leakage from the workpiece in the reducer, and the sealing performance inside the reducer housing will not be reduced due to the high temperature. In this application, the reducer is prevented from oil leakage through the heat dissipation holes and the oil seal. However, when the reducer is operating, the gears inside the reducer will mesh with each other for transmission, thereby achieving a lubrication effect. However, when the gears rotate for transmission, the fluidity of the lubricating oil inside the reducer will increase, thereby increasing the risk of the lubricating oil leaking from the reducer input shaft.

[0004] To solve the above problems, a vertical speed reducer with oil leakage prevention is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an oil leakage-proof vertical reducer. When the drive shaft rotates clockwise, the bevel disk arranged on one side of the outer surface of the drive shaft can rotate together. Therefore, after the bevel disk rotates clockwise, the lubricating oil located in the inner cavity of the box seat can enter the inner cavity of the oil drain pipe through the oil inlet pipe. At the same time, with the high-speed rotation of the bevel disk, the oil in the inner cavity of the oil drain pipe can be discharged at a high speed through the horizontal guide pipe and the vertical guide pipe. Since the horizontal guide pipe and the vertical guide pipe are evenly distributed on the surface of the bevel disk, when the bevel disk rotates at a high speed, the lubricating oil flowing out can form a high-speed flowing lubricating oil anti-skid layer through the horizontal guide pipe and the vertical guide pipe, thereby reducing the leakage of the lubricating oil from the opening of the rotating groove, which can solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an oil-leakage-proof vertical reducer, comprising a driving motor and a reducer connected to an output end on one side of the driving motor, the reducer comprising a box seat with a hollow inner cavity and an upper opening and a box cover fixedly connected to the upper opening of the box seat, a rotating groove is formed through one side of the outer surface of the box seat and the box cover, and an input shaft assembly coaxially fixedly connected to the output end of the reducer is provided in the inner cavity of the rotating groove;

[0013] Furthermore, an air inlet pipe is provided at the axis center of the inner cavity of the driving shaft extending to the inner cavity of the rotating disk. The air inlet pipe located in the inner cavity of the rotating disk extends outward along its axis center to provide a groove. An expandable expansion ring is sealed at the edge of the inner cavity wall of the groove, and a floating ring is sleeved on the outer surface of the expansion ring so as to expand and deform with the expansion ring.

[0014] Furthermore, a rotating shaft is arranged at the axis center of the inner cavity of the air intake pipe, a connecting rod is fixedly arranged between one side of the outer surface of the rotating shaft extending outward to the inner cavity wall of the air intake pipe, and a fan blade is fixedly arranged on one side of the outer surface of the rotating shaft.

[0015] Furthermore, an air inlet hole is provided on one side of the outer surface of the driving shaft and penetrates through the inner cavity of the rotating shaft, and an air inlet component with a right-angle structure is fixedly arranged at the upper opening of the air inlet hole.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention proposes an oil leakage-proof vertical reducer. When the driving shaft rotates clockwise, the bevel plate arranged on one side of the outer surface of the driving shaft can rotate together. Therefore, after the bevel plate rotates clockwise, the lubricating oil located in the inner cavity of the box seat can enter the inner cavity of the oil drain pipe through the oil inlet pipe. At the same time, with the high-speed rotation of the bevel plate, the oil in the inner cavity of the oil drain pipe can be discharged at a high speed through the horizontal guide pipe and the vertical guide pipe. Since the horizontal guide pipe and the vertical guide pipe are evenly distributed on the surface of the bevel plate, when the bevel plate rotates at a high speed, the lubricating oil flowing out can form a high-speed flowing lubricating oil anti-skid layer through the horizontal guide pipe and the vertical guide pipe, thereby reducing the leakage of the lubricating oil from the opening of the rotating groove.

[0020] 2. The present invention proposes an oil leakage-proof vertical reducer. When the inclined plate rotates, the rotation resistance of the horizontal guide pipe and the vertical guide pipe in the lubricating oil can be reduced through the oil inlet holes and the guide blocks arranged in an inclined structure. At the same time, part of the lubricating oil can enter the inner cavity of the horizontal guide pipe and the vertical guide pipe through the oil inlet holes, further improving the formation of a flowing lubricating oil anti-skid layer.

[0021] 3. The present invention proposes an oil-leakage-proof vertical reducer. When the driving shaft rotates at a high speed, the air intake component in a right-angle structure can automatically intake air under the high-speed rotation of the driving shaft. At the same time, as the rotating shaft rotates at a high speed, the fan blades continuously press the air pressure into the groove, thereby facilitating the expansion of the expansion ring, thereby facilitating the edge of the floating ring to fit and clamp with the inner wall of the sealing groove, thereby achieving a certain sealing effect.

[0022] 4. The present invention proposes an oil leakage-proof vertical reducer. After the driving shaft rotates, the right-angle tube in centrifugal telescopic state can lift the top block upward. After the top block moves upward, the dust cap can be driven to move upward through the connecting rod. After the dust cap moves upward, the dredging rod can be driven to move, thereby preventing the lubricating oil from leaking due to excessive pressure in the reducer cavity. After the driving shaft stops rotating, the right-angle tube retracts, thereby allowing the dust cap to automatically fall back, thereby preventing dust. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1 An oil-leakage-proof vertical reducer comprises a rotatable driving motor 1 and a reducer 2 connected to an output end on one side of the driving motor 1. The reducer 2 can reduce the power output of the high-speed rotating driving motor 1.

[0040] In order to solve the technical problem of oil leakage in the existing reducer 2, please refer to Figure 1-4 and Figure 9-10 , providing the following technical solutions:

[0041] The reducer 2 includes a box seat 21 with a hollow inner cavity and an open upper end, and a box cover 22 located at the upper end opening of the box seat 21 and fixedly connected by bolts. A rotating groove 23 coaxial with the output end of the reducer 2 is penetrated on one side of the outer surface of the box seat 21 and the box cover 22. The inner cavity of the rotating groove 23 is provided with an input shaft assembly 24 coaxially fixedly connected to the output end of the reducer 2. The inner cavities of the box seat 21 and the box cover 22 are meshed with each other and provided with a reduction gear set 25, and the reduction gear set 25 is meshed and connected with the input shaft assembly 24. The other side of the inner cavity of the rotating groove 23 is provided with an output shaft 26 that is decelerated by the reduction gear set 25. Therefore, after the input shaft assembly 24 rotates at a high speed, the reduction gear set 25 provided in the inner cavity of the box seat 21 and the box cover 22 can then reduce the power of the high-speed drive and output it from the output shaft 26.

[0042] The input shaft assembly 24 includes a drive shaft 241 located in the inner cavity of the rotating groove 23 and rotating coaxially. An end cover 246 that can seal the seam is clamped at an opening on one side of the outer surface of the rotating groove 23. A gasket 245 is provided at a fitting position on one side of the outer surface of the end cover 246, and one end of the drive shaft 241 passes through the axis of the gasket 245 and the end cover 246 in sequence.

[0043] The outer surface of the rotating groove 23 has an opening extending toward the inner wall of the box seat 21 to form a sealing groove 231. The outer surface of the driving shaft 241 located in the inner cavity of the sealing groove 231 is provided with a rotating disk 243. When the driving shaft 241 rotates at a high speed, the rotating disk 243 can rotate at a high speed. The outer surface of the rotating disk 243 has a bevel disk 2432 extending toward one end of the output shaft 26. The surface of the bevel disk 2432 is evenly distributed with oil inlet pipes 2433 with openings at both ends around the circumference thereof. The inner cavity of the oil inlet pipe 2433 is hollow. When the bevel disk 2432 rotates at a high speed, the lubricating oil in the inner cavity of the box seat 21 can pass through the oil inlet pipe 2433. A pair of oil drain pipes 2434 arranged in opposite directions are sealed at the end opening of the oil inlet pipe 2433 where the oil flows out. The bottom surface of the oil drain pipe 2434 is in contact with the surface of the inclined plate 2432, and the angle between the oil drain pipe 2434 and the oil inlet pipe 2433 is ninety degrees. The high-speed oil flowing in the inner cavity of the oil inlet pipe 2433 can be guided by the pair of oil drain pipes 2434.

[0044] A horizontal guide pipe 2438 and a vertical guide pipe 2439 are respectively arranged at the end openings of a pair of oil drain pipes 2434 for oil to flow out. Therefore, when the reducer 2 is in use, the driving motor 1 drives the driving shaft 241 to rotate at a high speed, so that the driving shaft 241 rotates clockwise. When the driving shaft 241 rotates clockwise, the inclined disk 2432 arranged on one side of the outer surface of the driving shaft 241 can rotate together. Therefore, after the inclined disk 2432 rotates clockwise, the lubricating oil in the inner cavity of the box seat 21 can pass through the oil inlet pipe 243 3 enters the inner cavity of the oil drain pipe 2434, and with the high-speed rotation of the inclined plate 2432, the oil in the inner cavity of the oil drain pipe 2434 can be discharged at a high speed through the horizontal guide pipe 2438 and the vertical guide pipe 2439. Since the horizontal guide pipe 2438 and the vertical guide pipe 2439 are evenly distributed on the surface of the inclined plate 2432, when the inclined plate 2432 rotates at a high speed, the outflowing lubricating oil can form a high-speed flowing lubricating oil anti-skid layer through the horizontal guide pipe 2438 and the vertical guide pipe 2439, thereby reducing the leakage of the lubricating oil from the opening of the rotating groove 23.

[0045] A guide block 2435 is fixedly installed on the surface of the rotating lubricating oil meeting surface of the horizontal guide pipe 2438 and the vertical guide pipe 2439, and an oil inlet hole 2436 with an inclined structure is opened on the front side of the guide block 2435 and penetrates into the inner cavity of the horizontal guide pipe 2438 and the vertical guide pipe 2439. Therefore, when the inclined plate 2432 rotates, the oil inlet hole 2436 and the guide block 2435 with an inclined structure can reduce the rotational resistance of the horizontal guide pipe 2438 and the vertical guide pipe 2439 in the lubricating oil. At the same time, part of the lubricating oil can enter the inner cavity of the horizontal guide pipe 2438 and the vertical guide pipe 2439 through the oil inlet hole 2436, further improving the formation of a flowing lubricating oil anti-skid layer.

[0046] To solve the existing technical problems of high pressure oil leakage, please refer to Figure 5 , Figure 6-9 and Figure 11-14 , providing the following technical solutions:

[0047] An air inlet pipe 2412 is provided at the axis center of the inner cavity of the driving shaft 241 and extends to the inner cavity of the rotating disk 243. The air inlet pipe 2412 located in the inner cavity of the rotating disk 243 extends outward along its axis center and is provided with a groove 2431. The groove 2431 is located in the inner cavity of the sealing groove 231, and an expandable expansion ring 2437 is sealed at the edge of the inner cavity wall of the groove 2431. A floating ring 244 that can expand and deform with the expansion ring 2437 is sleeved on the outer surface of the expansion ring 2437.

[0048] A rotating shaft 2413 is provided at the inner axis of the air inlet pipe 2412, and a connecting rod 2415 is fixedly provided between the outer surface of the rotating shaft 2413 and the inner wall of the air inlet pipe 2412. When the driving shaft 241 is rotated by the connecting rod 2415, the connecting rod 2415 can drive the rotating shaft 2413 to rotate together. A fan blade 2414 is fixedly provided on one side of the outer surface of the rotating shaft 2413. When the driving shaft 241 is rotated at a high speed, the fan blade 2414 can be driven to rotate at a high speed by the rotating shaft 2413. After the fan blade 2414 rotates, the inner cavity of the groove 2431 can be continuously pressurized. After the inner cavity pressure of the groove 2431 is continuously increased, the expansion ring 2437 can expand outwards. After the expansion ring 2437 expands outwards, the floating ring 244 can be expanded together.

[0049] An air inlet hole 2411 is provided on one side of the outer surface of the drive shaft 241, which penetrates through the inner cavity of the rotating shaft 2413. Through the air inlet hole 2411, the gas outside the drive shaft 241 can enter the inner cavity of the air inlet pipe 2412, thereby facilitating the expansion of the expansion ring 2437. An air inlet component 242 with a right-angle structure is fixedly provided at the upper opening of the air inlet hole 2411. When the drive shaft 241 rotates at a high speed, the air inlet component 242 with a right-angle structure can automatically inlet air under the high-speed rotation of the drive shaft 241. At the same time, as the rotating shaft 2413 rotates at a high speed, the fan blades 2414 continuously press the air pressure into the groove 2431, thereby facilitating the expansion of the expansion ring 2437, thereby facilitating the edge of the floating ring 244 and the inner cavity wall of the sealing groove 231 to fit and clamp each other, thereby achieving a certain sealing effect.

[0050] The air intake assembly 242 includes a connecting tube 2421 coaxially arranged with the upper end opening of the air intake hole 2411, and a pair of limiting grooves 2424 are respectively opened on the opposite walls of the inner cavity of the connecting tube 2421, and the inner cavity of the connecting tube 2421 is provided with a right-angle tube 2422 which can be telescopically displaced along its inner cavity, and a limiting block 2425 with one end clamped in the inner cavity of the limiting groove 2424 is provided at the lower edge of the right-angle tube 2422 located in the inner cavity of the connecting tube 2421. When the right-angle tube 2422 is rotated by the driving shaft 241 under the action of the centrifugal force, the right-angle tube 2422 can be telescopically displaced along the inner cavity of the connecting tube 2421 through the limiting groove 2424 and the limiting block 2425, thereby preventing it from rotating during telescoping. A spring 2423 is fixedly provided from the outer surface of the connecting tube 2421 to the upper end of the connecting tube 2421. When the driving shaft 241 rotates at a high speed, the rotating centrifugal force of the driving shaft 241 can extend the right-angle tube 2422. The stretching resilience of the spring 2423 can realize that when the right-angle tube 2422 is extended and the centrifugal force is smaller than the spring 2423, the spring 2423 can pull the right-angle tube 2422 to retract.

[0051] A pressure relief pipe 221 is provided at the top of the box cover 22 to relieve the pressure in the inner cavity of the reducer 2. A telescopically movable dust cap 222 is sleeved at the upper opening of the pressure relief pipe 221. The dust cap 222 covers the upper opening of the pressure relief pipe 221 to prevent dust from entering the inner cavity of the pressure relief pipe 221, thereby preventing dust from affecting the lubricity of the lubricating oil inside the reducer 2. A dredging rod 223 whose end is plugged into the inner cavity of the pressure relief pipe 221 is provided on the bottom surface of the dust cap 222 located at the upper opening of the pressure relief pipe 221. After the dust cap 222 is telescopically moved, the dredging rod 223 can move up and down with the dust cap 222. After the dredging rod 223 moves up and down, the dredging rod 223 can prevent the inner cavity of the pressure relief pipe 221 from being blocked, thereby achieving a dredging effect.

[0052] A limiting ring 225 coaxial with the driving shaft 241 is provided on one side of the outer surface of the box cover 22, and a connecting rod 224 with one end penetrating the limiting ring 225 is fixedly provided at the top of the dust cap 222. When the connecting rod 224 is telescopically displaced up and down, the inner ring diameter of the limiting ring 225 matches the diameter of the connecting rod 224, thereby achieving a telescopic limiting effect on the connecting rod 224. A top block 226 whose bottom surface is attached to the upper end of the right-angle tube 2422 is fixedly provided at the end of the connecting rod 224, and both ends of the top block 226 are arranged in an arc-shaped structure, thereby facilitating the right-angle tube 2422 in centrifugal telescoping to push the top block 226 to move upward. After the driving shaft 241 rotates, the right-angle tube 2422 in centrifugal extension can lift the top block 226 upward. After the top block 226 moves upward, the dust cap 222 can be driven to move upward together through the connecting rod 224. After the dust cap 222 moves upward, the unblocking rod 223 can be driven to move, thereby preventing the lubricating oil from leaking due to excessive pressure in the inner cavity of the reducer 2. At the same time, when the unblocking rod 223 moves up and down, the unblocking rod 223 can prevent the inner cavity of the pressure relief pipe 221 from being blocked, thereby achieving the effect of unblocking. After the driving shaft 241 stops rotating, the right-angle tube 2422 retracts, thereby allowing the dust cap 222 to automatically fall back and cover the upper end opening of the pressure relief pipe 221, thereby preventing dust.
