AI Technical Summary
Existing active bevel gears suffer from poor lubrication, increased wear, and reduced strength and lifespan because the lubricating oil cannot penetrate evenly into the tooth gaps during use.
An active bevel gear with an oiling shell and an oiling component was designed. By setting oil seepage holes on the side wall of the oiling shell and a detachable oil-absorbing sponge oiling component, the oil-absorbing sponge absorbs lubricating oil and compresses and deforms, so as to accurately seep into the gap between the teeth for lubrication.
This achieves uniform penetration of lubricating oil, reduces the amount of lubricating oil used, improves lubrication effect, extends the service life of bevel gears, and reduces costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of gear technology, specifically to a driving bevel gear. Background Technology
[0002] Gear transmission is a type of mechanical transmission. It offers high accuracy, efficiency, compact structure, reliable operation, and long service life. The driving bevel gear is one of the components that enables gear transmission.
[0003] The existing driving bevel gear includes a gear body and a mounting shaft. The end of the mounting shaft away from the gear body is provided with an external spline. The gear body is truncated cone-shaped, and its sidewalls are provided with a number of teeth arranged in a ring array.
[0004] In operation, two or more bevel gears typically mesh to achieve transmission. However, with increasing usage time, bevel gears inevitably experience wear, reducing transmission accuracy and shortening their strength and lifespan. The most common method to reduce wear is to apply lubricating oil to the surface of the bevel gears, allowing it to penetrate the gaps between the teeth and effectively reduce wear during use. However, due to the numerous, narrow, and deep gaps between the teeth, applying lubricating oil to the surface using existing methods results in a large amount of lubricating oil being blocked by the teeth, failing to penetrate evenly into each gap. Instead, it tends to run off the surface of the bevel gears, leading to uneven lubrication and poor lubrication effectiveness. Utility Model Content
[0005] The purpose of this invention is to provide an active bevel gear to solve the above-mentioned problems.
[0006] This utility model achieves the above-mentioned objective through the following technical solution: an active bevel gear, comprising a gear body and a mounting shaft, wherein the gear body includes a plurality of teeth, and the gear body is provided with a top-opening oil filling shell, the oil filling shell being frustoconical in shape, and a plurality of oil seepage holes being provided on the side wall of the oil filling shell, the oil seepage holes corresponding to the gap positions of adjacent teeth, and an oil filling component being detachably installed inside the oil filling shell, the oil filling component including an oil-absorbing sponge for embedding inside the oil filling shell, and a cover plate for sealing the oil filling shell being provided on the oil-absorbing sponge.
[0007] As a further feature of this invention, the total thickness of the oil-absorbing sponge and the cover plate is greater than the depth of the refill shell.
[0008] As a further feature of this invention, a threaded sleeve is provided at the center of the gear body, and a threaded tube matching the threaded sleeve is provided at the center of the cover plate.
[0009] As a further feature of this invention, a sealing ring is provided on the side wall of the cover plate, and the sealing ring is made of nitrile rubber.
[0010] As a further feature of this invention, the threaded tube is provided with a grip handle.
[0011] As a further feature of this invention, both the gear body and the mounting shaft are made of carburized steel.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] When lubricating oil needs to be added, this utility model simply requires removing the oiling component from the oiling shell, immersing the oil-absorbing sponge in the lubricating oil until it is saturated, and then reinstalling the oiling component into the oiling shell, allowing the oil-absorbing sponge to embed itself inside. The cover plate then compresses the sponge, squeezing out the lubricating oil from the sponge and allowing it to seep through the seepage holes, precisely flowing into the gaps between the gear teeth. This allows for lubrication of all gaps at once, is convenient to operate, reduces lubricating oil usage, lowers costs, and ensures uniform lubrication, thus guaranteeing the lubrication effect of the bevel gear.

[0019] 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.
[0020] Please see Figure 1-4 As shown, the driving bevel gear includes a gear body 1 and a mounting shaft 2. Both the gear body 1 and the mounting shaft 2 are made of carburized steel, which has good wear resistance, thus giving the driving bevel gear good durability. The gear body 1 includes several teeth 3, and a top-opening oil filling shell 4 is provided on the gear body 1. The oil filling shell 4 is frustum-shaped, and several oil seepage holes 5 are opened on the side wall of the oil filling shell 4, and the oil seepage holes 5 correspond to the gap positions of adjacent teeth 3. An oil filling component is detachably installed inside the oil filling shell 4. The oil filling component includes an oil-absorbing sponge 6 for embedding inside the oil filling shell 4, and a cover plate 7 for sealing the oil filling shell 4 is provided on the oil-absorbing sponge 6. When it is necessary to add lubricating oil, simply remove the oil filling component from the oil filling shell 4 and then immerse the oil-absorbing sponge 6 in the lubricating oil. The oil-absorbing sponge 6 is saturated with lubricating oil, and then the oil-lubricating component is reinstalled inside the oil-lubricating shell 4, allowing the oil-absorbing sponge 6 to embed inside the oil-lubricating shell 4. The cover plate 7 then absorbs the oil-absorbing sponge 6, causing it to compress and deform, thereby squeezing out the lubricating oil inside the sponge 6 and allowing it to seep out through the oil seepage hole 5, precisely flowing into the gaps of the teeth 3. This allows for lubrication of all gaps at once, making the operation convenient, reducing the use of lubricating oil, lowering costs, and ensuring uniform lubrication, thus guaranteeing the lubrication effect of the bevel gear. The total thickness of the oil-absorbing sponge 6 and the cover plate 7 is greater than the depth of the oil-lubricating shell 4. Therefore, when the oil-lubricating shell 4 is closed by the cover plate 7, the oil-absorbing sponge 6 will be compressed and deformed, squeezing out the absorbed lubricating oil and allowing it to seep out through the oil seepage hole 5, achieving lubrication. The operation is relatively convenient.
[0021] Please see Figure 2-4 As shown, a threaded sleeve 8 is provided at the center of the gear body 1, and a threaded tube 9 matching the threaded sleeve 8 is provided at the center of the cover plate 7. By screwing the threaded tube 9 into the threaded sleeve 8, the cover plate 7 can be fixedly installed onto the oil filling shell 4, thereby sealing the oil filling shell 4 and realizing the installation of the oil filling component. When it is necessary to disassemble the oil filling component, simply unscrew the threaded tube 9 from the threaded sleeve 8, making the disassembly and assembly of the oil filling component convenient and simple. A handle 11 is provided on the threaded tube 9. When it is necessary to screw the cover plate 7 into or out of the threaded sleeve 8, the handle 11 can be held to apply force. The handle 11 can be used as the force point for screwing the cover plate 7, making the operation easier and less strenuous. A sealing ring 10 is provided on the side wall of the cover plate 7, and the sealing ring 10 is made of nitrile rubber. After the oil filling shell 4 is closed by the cover plate 7, the sealing ring 10 can seal the gap between the cover plate 7 and the oil filling shell 4, preventing the lubricating oil inside the oil filling shell 4 from seeping out, thereby preventing the loss and waste of lubricating oil.
