[0002] Bevel gears, also known as bevel gears, are widely used in industrial transmission equipment, vehicle differentials, locomotives, ships, power plants, steel mills, railway track inspection, etc. When using bevel gears, a drive shaft mechanism needs to be installed.

[0003] In modern times, if lubricating oil is not added in a timely manner during the use of traditional integral spiral bevel gears, it will lead to greater wear and thus affect the service life of the integral spiral bevel gears. Utility Model Content

[0004] The purpose of this utility model is to provide a novel bevel gear and its transmission shaft mechanism. The oil tank of the lubrication assembly is connected to the first channel and the second channel through the oil inlet pipe and the oil outlet pipe, respectively, which can realize the directional delivery and circulation of lubricating oil, ensure the lubrication effect of the bevel gear, reduce friction loss, and improve transmission efficiency. The plug at the oil inlet of the oil outlet pipe can conveniently control the outflow of lubricating oil.

[0005] This utility model is achieved through the following technical solution:

[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 1-6 This utility model provides a technical solution: a novel bevel gear, including a bevel gear assembly 1, which includes two bevel gears 101. One end of each bevel gear 101 is provided with a first arc-shaped plate 102, and the other end of each bevel gear 101 is provided with two second arc-shaped plates 103. The first arc-shaped plate 102 is externally threaded with a first threaded sleeve 3, and the second arc-shaped plate 103 is externally threaded with a second threaded sleeve 4. An installation groove 106 is provided on the bevel gear 101, and an oil lubrication assembly 5 is installed and fitted in the installation groove 106. The first arc-shaped plate 102 at one end of the bevel gear 101 is threadedly engaged with the first threaded sleeve 3, and the two second arc-shaped plates 103 at the other end are threadedly engaged with the second threaded sleeve 4. This design achieves tight installation and fixation of components through threaded connection, which is convenient for disassembly and assembly, and facilitates maintenance and replacement of parts.

[0026] Each of the two bevel gears 101 has a slot 104 on one end of its sidewall, and a retaining plate 105 is installed on the other end of its sidewall. The retaining plate 105 fits into the slot 104. The slot 104 and retaining plate 105 on the sidewall of the two bevel gears 101 cooperate with each other, enabling the two bevel gears 101 to achieve precise positioning when connected, ensuring the meshing accuracy between the bevel gears, improving the stability and accuracy of the transmission, and reducing vibration and noise during the transmission process.

[0027] The bevel gear 101 has a first channel 107 and a second channel 108. The first channel 107 and the second channel 108 are connected and disposed on the mounting groove 106. The mounting groove 106 on the bevel gear 101 is used to install the lubrication assembly 5. The first channel 107 and the second channel 108 are connected to the mounting groove 106 to provide a channel for the delivery and circulation of lubricating oil, ensuring that the key parts of the bevel gear are well lubricated, reducing wear, and extending service life.

[0028] The lubrication assembly 5 includes an oil tank 501, with an oil inlet pipe 502 and an oil outlet pipe 503 connected to the oil tank 501. The oil inlet pipe 502 is installed inside the first channel 107, and the oil outlet pipe 503 is installed inside the second channel 108. The oil tank 501 of the lubrication assembly 5 is connected to the first channel 107 and the second channel 108 through the oil inlet pipe 502 and the oil outlet pipe 503, respectively, which can realize the directional delivery and circulation of lubricating oil, ensure the lubrication effect of the bevel gear, reduce friction loss, and improve transmission efficiency.

[0029] The oil outlet pipe 503 has a threaded seal 504 at the oil inlet. The seal 504 at the oil inlet of the oil outlet pipe 503 can conveniently control the flow of lubricating oil. When maintenance or to prevent lubricating oil leakage is required, the seal 504 can be tightened to stop the flow of lubricating oil and improve the controllability and reliability of the lubrication system.

[0030] A spring 6 is installed on the bottom surface inside the oil drum 501. A first movable plug 7 is installed on the top of the spring 6. The first movable plug 7 slides inside the oil drum 501. A connecting rod 8 is set on the top of the first movable plug 7. A second movable plug 9 is set on the top of the connecting rod 8. The cooperation between the spring 6 inside the oil drum 501, the first movable plug 7, the connecting rod 8, and the second movable plug 9 utilizes the elastic force of the spring 6 to push the first movable plug 7 to slide inside the oil drum 501. In turn, the connecting rod 8 drives the second movable plug 9 to move, thereby realizing the regulation of the lubricating oil pressure inside the oil drum 501 and ensuring that the lubricating oil can be stably supplied to the lubrication part of the bevel gear under different working conditions.

[0031] A drive shaft mechanism includes a drive shaft 2 disposed between two bevel gears 101. A side plate 201 is mounted on one end of the drive shaft 2, and a cylinder 202 is disposed on the side plate 201. The cylinder 202 is fitted between two second arc-shaped plates 103. A first threaded sleeve 3 and a second threaded sleeve 4 are both disposed on the drive shaft 2. The cylinder 202 disposed on the side plate 201 at one end of the drive shaft 2 and fitted between the two second arc-shaped plates 103 provides a stable support structure for the connection between the drive shaft 2 and the bevel gears 101, enhances the connection strength between the drive shaft and the bevel gears, and ensures that power can be reliably transmitted from the drive shaft to the bevel gears.

[0032] Both the first threaded sleeve 3 and the second threaded sleeve 4 are mounted on the transmission shaft 2. They not only tightly connect the bevel gear 101 to the transmission shaft 2, but also adjust the relative position between the bevel gear and the transmission shaft to a certain extent to adapt to different working requirements and improve the flexibility and adaptability of the entire mechanism.

[0033] When using the new bevel gear and its transmission shaft mechanism, the transmission shaft 2 is located inside the bevel gear assembly 1. The first threaded sleeve 3 and the second threaded sleeve 4 are rotated by the thread, so that the first threaded sleeve 3 is installed on the first arc plate 102 of the bevel gear assembly 1, and the second threaded sleeve 4 is installed on the second arc plate 103, ensuring the relative installation between the bevel gear assembly 1 and the transmission shaft 2. An oil lubrication assembly 5 is installed between the two bevel gears 101. When the bevel gear assembly 1 rotates, the second movable plug 9 inside the oil lubrication assembly 5 is pressed, so that the lubricating oil inside the oil lubrication assembly 5 is discharged, ensuring the lubrication operation of the bevel gear assembly 1 during use.

[0034] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
