Description

Technical Field

[0001] This utility model relates to the field of gearbox housing technology, specifically to a gearbox housing that prevents oil leakage. Background Technology

[0002] A speed reducer is an independent component consisting of gear drives, worm drives, or gear-worm drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a driven machine. It plays a role in matching speeds and transmitting torque between the prime mover and the driven machine or actuator, and its applications are extremely widespread in modern machinery.

[0003] In current gearboxes, the extended shaft is typically used to connect to other equipment. However, a common problem during operation is that once the oil seal on the gearbox housing wears excessively, internal oil will seep out along the shaft, causing oil leakage. The current solution is usually to replace the oil seal. While this effectively stops further leakage, it has significant drawbacks in practical use, such as:

[0004] While replacing the oil seal can effectively stop the continued leakage of oil, the oil seal itself is a consumable. Each replacement is only discovered and addressed after it has been damaged and caused oil leakage, which leads to a continuous decrease in the oil inside the reducer, thus affecting the operation of the reducer.

[0005] Therefore, a leak-proof gearbox housing designed to reduce oil waste is now being developed to address this defect. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an oil-leakage-proof gearbox housing, which solves the problem of easy oil leakage and reduced internal oil volume in existing gearboxes.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an oil leak-proof reducer housing, including a reducer body, a rotating shaft is provided on the surface of the reducer body through an opening, an oil seal cylinder is installed on the surface of the reducer body and is sleeved on the surface of the rotating shaft, a first rubber ring is fixedly installed at the rear of the inner cavity of the oil seal cylinder and the first rubber ring is in contact with the surface of the rotating shaft, and an oil storage part is provided at the bottom of the oil seal cylinder.

[0008] Preferably, the front part of the inner cavity of the oil seal cylinder is fixedly connected to an oil guide ring frame that cooperates with the oil storage part by a fixing block, and a plurality of oil guide ring frames are provided. A second rubber ring is fixedly installed on the inner side of the oil guide ring frame, and the second rubber ring is in contact with the surface of the rotating shaft. A drain pipe is fixedly installed at the bottom of the oil storage part by opening an opening.

[0009] Preferably, a liquid pump is fixedly connected to the upper part of the surface of the reducer body via a fixing block, a liquid pumping pipe is installed at the bottom of the liquid pump, a first threaded pipe that works with a drain pipe is fixedly connected to the end of the liquid pump away from the liquid pump, an injection pipe is installed at the top of the liquid pump, and a threaded sleeve is fixedly connected to the end of the injection pipe away from the liquid pump.

[0010] Preferably, a filter oil box is fixedly installed on the top of the reducer body, and a pull-out opening is provided on the right side of the filter oil box. A concave frame is slidably installed on the inner side of the pull-out opening, and a filter cloth is provided on the inner side of the concave frame.

[0011] Preferably, the top of the filter oil box is fixedly connected to a second threaded tube that cooperates with the guide port through an opening. Guide ports are provided on both sides of the top of the filter oil box. A curved sealing frame that cooperates with the concave frame is slidably installed between the inner sides of the two guide ports, and the curved sealing frame is sleeved on the surface of the second threaded tube.

[0012] Preferably, the bottom of the filter oil box is fixedly connected to a return oil pipe through an opening, and the bottom end of the return oil pipe passes through the reducer body and extends to the inside of the reducer body.

[0013] Beneficial effects

[0014] This utility model provides an oil leakage-proof gearbox housing. Compared with the prior art, it has the following advantages:

[0015] (1) The oil leakage-proof reducer housing is constructed by installing an oil seal cylinder on the surface of the reducer body, and setting a first rubber ring, an oil guide ring frame, and a second rubber ring inside the oil seal cylinder, which are used in conjunction with a concave frame and a filter cloth. The structure can protect and isolate the rotating shaft by using the first rubber ring and multiple second rubber rings to prevent oil leakage along the rotating shaft. The function of the oil guide ring frame is to allow the oil to accumulate in the oil storage part after the oil comes into contact with the second rubber ring, and then use a pump to draw the oil into the filter oil box, where the filter cloth filters the oil and re-injects it into the reducer body. This not only prevents oil leakage but also allows for oil recycling, ensuring the stability of the reducer body's operation.

[0016] (2) The oil leakage prevention reducer housing is equipped with a concave frame and filter cloth inside the filter oil box, and is used in conjunction with a second threaded pipe and a bent sealing frame. The structure can be disassembled by connecting the threaded sleeve and the second threaded pipe, and the bent sealing frame can be pressed to fix the concave frame. This makes it easy for the staff to quickly remove the concave frame and replace the filter cloth, ensuring the filtration quality and improving the overall practicality and functionality of the equipment.

[0024] 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.

[0025] Please see Figure 1-6This utility model provides a technical solution: an oil leak-proof reducer housing, including a reducer body 1, a rotating shaft 3 with an opening on the surface of the reducer body 1, an oil seal cylinder 2 installed on the surface of the reducer body 1, and the oil seal cylinder 2 sleeved on the surface of the rotating shaft 3, a first rubber ring 4 fixedly installed at the rear of the inner cavity of the oil seal cylinder 2, and the first rubber ring 4 is in contact with the surface of the rotating shaft 3, and an oil storage part 5 is provided at the bottom of the oil seal cylinder 2.

[0026] Furthermore, the front part of the inner cavity of the oil seal cylinder 2 is fixedly connected to an oil guide ring frame 6 that cooperates with the oil storage part 5 by a fixing block, and several oil guide ring frames 6 are provided. A second rubber ring 7 is fixedly installed on the inner side of the oil guide ring frame 6, and the second rubber ring 7 is in contact with the surface of the rotating shaft 3. A drain pipe 8 is fixedly installed at the bottom of the oil storage part 5 by opening. A liquid pump 9 is fixedly connected to the upper part of the surface of the reducer body 1 by a fixing block. A liquid pump pipe 10 is installed at the bottom of the liquid pump 9. The liquid pump pipe 10 is a retractable hose. A first threaded pipe 11 that cooperates with the drain pipe 8 is fixedly connected to the end of the liquid pump pipe 10 away from the liquid pump 9. An injection pipe 12 is installed at the top of the liquid pump 9, and a threaded sleeve 13 is fixedly connected to the end of the injection pipe 12 away from the liquid pump 9.

[0027] Before use, first install the oil seal cylinder 2 with the reducer body 1, and then put the oil seal cylinder 2 on the surface of the rotating shaft 3. Then, tighten the first threaded pipe 11 and the drain pipe 8 by rotation. At this time, the first rubber ring 4 and the second rubber ring 7 will wrap the surface of the rotating shaft 3. Then, pull the concave frame 16 out from the inside of the filter oil box 14 and put the filter cloth 17 into the inside of the concave frame 16. Then push the concave frame 16 back into the filter oil box 14. Then tighten the threaded sleeve 13 and the second threaded pipe 18. When the threaded sleeve 13 is completely turned to the bottom, the threaded sleeve 13 will press down the bent seal frame 20. After the bent seal frame 20 descends, it will insert into the inside of the concave frame 16, fixing the concave frame 16 to the inside of the filter oil box 14.

[0028] The filter oil box 14 is fixedly installed on the top of the reducer body 1. A pull-out port 15 is opened on the right side of the filter oil box 14. A concave frame 16 is slidably installed on the inner side of the pull-out port 15. A filter cloth 17 is provided on the inner side of the concave frame 16. A second threaded pipe 18 that cooperates with the guide port 19 is fixedly connected to the top of the filter oil box 14 through an opening. Guide ports 19 are opened on both sides of the top of the filter oil box 14. A bent sealing frame 20 that cooperates with the concave frame 16 is slidably installed between the inner sides of the two guide ports 19. The bent sealing frame 20 is sleeved on the surface of the second threaded pipe 18. A return oil pipe 21 is fixedly connected to the bottom of the filter oil box 14 through an opening. The bottom end of the return oil pipe 21 passes through the reducer body 1 and extends to the inner side of the reducer body 1.

[0029] During use, the rotating shaft 3 is driven to rotate. During the rotation of the rotating shaft 3, the first rubber ring 4 can block the oil on the surface of the rotating shaft 3 to prevent the oil from leaking along the rotating shaft 3. If the first rubber ring 4 is damaged and cannot effectively isolate the oil, when the oil flows along the rotating shaft 3 and is blocked by the second rubber ring 7, the oil will enter the oil guide ring frame 6 and drip into the oil storage part 5 for storage by the guide of the oil guide ring frame 6. Then, after the pump 9 is started, the oil inside the oil storage part 5 is extracted by the pumping pipe 10 and injected into the inside of the filter oil box 14 by the injection pipe 12. After the oil falls into the filter oil box 14, it is filtered by the filter cloth 17. Then the filtered oil flows back into the interior of the reducer body 1 through the return oil pipe 21.
