Description

Technical Field

[0001] The utility model relates to the technical field of gearbox gears, in particular to a heat dissipation type gearbox gear. Background Art

[0002] The gearbox is a common mechanical device used to transmit power in vehicles or mechanical equipment and control the speed and torque of the output wheel shaft. When high power output or high torque is required, the gearbox gears can achieve different speed and torque output of the vehicle. Through the combination of gears of different sizes, the transmission ratio of the vehicle can be adjusted to achieve performance requirements under different working conditions such as low speed and high torque and high speed and low torque.

[0003] After searching, the Chinese patent document announcement number: CN212004159U discloses a heat dissipation type gearbox, which belongs to the technical field of gearbox gears. It solves the problem of large mass and poor heat dissipation effect of existing gearbox gears. The heat dissipation type gearbox gear is split and consists of a left half gear body formed by aluminum die casting and a right half gear body formed by cast iron casting. The left half gear body and the right half gear body are provided with a plurality of gear teeth corresponding to each other. A convex shaft portion is axially protruded outward from the middle of the left half gear body, and an axial hole for the convex shaft portion to be inserted and engaged is provided in the middle of the right half gear body. A plurality of reinforcing connecting portions are uniformly protruded on the outer peripheral wall of the convex shaft portion in the circumferential direction, and a plurality of reinforcing connecting grooves uniformly distributed in the circumferential direction and connected to the axial hole for the corresponding reinforcing connecting portion to be inserted and engaged are provided on the right half gear body. A convex ring is convexly provided between the gear teeth and the convex shaft portion on the inner end surface of the left half gear body. The utility model has the advantages of achieving lightweight requirements and good heat dissipation effect.

[0004] The beneficial effects of the above patent specification mention that "the gearbox gear is separated to form a left half gear body and a right half gear body. The left half gear body is formed by aluminum die casting, and the right half gear body is formed by cast iron casting. This reduces the overall product quality and achieves a lightweight effect. Traditional aluminum and iron are difficult to weld through conventional welding technology. Therefore, the left half gear body and the right half gear body are initially fixed by the engagement of the convex ring and the concave ring groove, the engagement of the convex shaft part and the shaft hole, and the engagement of the reinforced connecting part and the reinforced connecting groove, and then an integrated gear can be formed through conventional welding methods." Although the above patent can solve the problem that aluminum and iron are difficult to weld and achieve product lightweighting through structural engagement, in some existing technologies, it is difficult to add lubricating oil to the gear in time during operation, which leads to increased friction between the gear tooth surfaces and generates a lot of heat, thereby causing wear on the gear surface, shortening the service life of the gear, and causing equipment damage or shutdown. Therefore, in response to the above shortcomings, a heat dissipation type gearbox gear is proposed. Utility Model Content

The top of the oil inlet pipe 15 is fixedly connected to the bottom of the oil tank 13, and the bottom of the oil inlet pipe 15 contacts the top of the oil delivery block 7. Through the centrifugal force generated when the gear body 1 rotates, the sliding of the square slider 3 and the sliding rod 4, and then through the cooperation of the connecting pipe 8, the oil inlet pipe 15 and the oil outlet pipe 11, the lubricating oil is added when the gear is running. The lubricating oil has a cooling effect when the gear is running, and can effectively absorb and take away the heat generated when the gear moves, and reduce friction and wear, extend the life of the gear, and maintain the stability and reliability of the system. Annular grooves 12 are provided on the upper and lower sides of the gear body 1, and the bottom inner wall of the upper annular groove 12 is fixedly connected to a plurality of oil tanks 13 for storing lubricating oil. The top of the oil tank 13 is rotatably connected to a cover plate 14 for opening the oil tank 13 to refuel when the lubricating oil is used up. A heat dissipation component is fixedly connected to the top of the gear body 1.

[0027] The inner wall of the upper annular groove 12 is fixedly connected with a plurality of inclined plates 16, which are used to stir the air to dissipate heat for the gear body 1 when the gear rotates. A groove 17 is provided inside the gear body 1 for engaging the rotating shaft. The proximal sides of the plurality of springs 5 ​​are respectively fixedly connected to the distal sides of the plurality of square sliders 3, and the distal sides of the plurality of springs 5 ​​are respectively fixedly connected to the proximal sides of the plurality of fixed blocks 6. The proximal sides of the plurality of buffer rings 10 are in contact with the distal sides of the plurality of oil delivery blocks 7.

[0028] like Figure 1 , Figure 4 and Figure 5The heat dissipation component includes a protective ring 18, and a plurality of fan blades 19 are fixedly connected to the inside of the protective ring 18. The protective ring 18 is used to protect the fan blades 19 to prevent damage. A connecting ring 20 is fixedly connected to the adjacent side of the plurality of fan blades 19, and a plurality of connecting plates 21 are fixedly connected to the outside of the protective ring 18 for connecting the gear body 1 and the protective ring 18. The internal rotation of the connecting plate 21 is connected with a bolt 22. Through the rotation of the fan blade 19 and the connection between the connecting plate 21 and the bolt 22, the heat dissipation of the gear body 1 is achieved, thereby reducing the temperature, maintaining the performance of the lubricating oil stable, improving the lubrication effect, thereby improving the transmission efficiency, and reducing energy loss. A nut 23 is fixedly connected to the top of the bolt 22. The bottom end of the protective ring 18 contacts the top of the gear body 1, and the plurality of bolts 22 are threadedly connected to the gear body 1.

[0029] Working principle: when the gear body 1 rotates, the square slider 3 slides due to the centrifugal force generated by the rotation of the gear body 1. When the square slider 3 slides through the cavity 2, it drives the sliding rod 4 to slide outward. At this time, the oil delivery block 7 will be subjected to the pressure of the sliding rod 4 and move outward, and the spring 5 will also be compressed by the pressure of the sliding rod 4. When the oil delivery block 7 moves to contact the buffer ring 10, the connecting pipe 8 and the oil inlet pipe 15 are connected, and the lubricating oil in the oil tank 13 flows into the buffer ring 10 through the oil inlet pipe 15 and the connecting pipe 8, and then flows out through the oil outlet pipe 11. When the gear body 1 stops rotating, as the centrifugal force disappears, the square slider 3 will slide back to its original position due to the pressure generated by the compression of the spring 5, thereby driving the oil delivery block 7 back to its original position and causing the oil inlet pipe 15 and the connecting pipe 8 to be misaligned, thereby achieving the control of the lubricating oil from flowing out, and realizing the addition of lubricating oil when the gear body 1 is running. The lubricating oil has a cooling effect when the gear is running, which can effectively absorb and take away the heat generated when the gear moves, and reduce friction and wear, extend the life of the gear, and maintain the stability and reliability of the system.

[0030] When the gear body 1 rotates, the inclined plate 16 arranged in the annular groove 12 can stir the airflow to reduce the heat on the surface of the gear body 1. The connecting plate 21 is connected to the gear body 1 through the bolts 22 to drive the protection ring 18 to rotate, thereby driving the rotation of the fan blade 19. The air is blown to the surface of the gear body 1 through the rotation of the fan blade 19, and the excess lubricating oil on the gear body 1 is blown off, so that only a layer of lubricating oil protective film is formed, thereby preventing the high pressure generated when the gears are meshing from damaging the tooth surface due to the excess lubricating oil, thereby achieving heat dissipation through the fan blade 19, which can reduce the temperature, maintain the stability of the performance of the lubricating oil, improve the lubrication effect, thereby improving the transmission efficiency and reducing energy loss.
