Description

Technical Field

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

[0002] A gearbox is a device that changes the operating speed or traction of machines such as machine tools, automobiles, and tractors. It is usually composed of many gears of different diameters. The power output gear in the gearbox, as a key component for transmitting power, is subjected to tremendous pressure and friction during operation. Therefore, its heat dissipation performance and structural strength are particularly important. However, the traditional power output gear design often focuses on the transmission efficiency and structural stability of the gear. In a high-load, high-speed working environment, the heat dissipation problem of the gear has become a key factor affecting its service life and stability. Although lubricating oil can lubricate and cool to a certain extent, due to the limitations of the gear structure, the flow of lubricating oil inside the gear is not uniform, resulting in limited heat dissipation effect. Therefore, we propose a gearbox power output gear to solve the above problems. Utility Model Content

[0003] The main purpose of the utility model is to provide a gearbox power output gear, which solves the problem that traditional power output gear design often focuses on the transmission efficiency and structural stability of the gear. Under high-load and high-speed working environments, the heat dissipation problem of the gear becomes a key factor affecting its service life and stability. Although the lubricating oil can play a role in lubrication and cooling to a certain extent, due to the limitations of the gear structure, the flow of the lubricating oil inside the gear is not uniform, resulting in limited heat dissipation effect.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A gearbox power output gear comprises a gear, wherein a plurality of auxiliary mechanisms are arranged inside the gear, wherein the auxiliary mechanisms comprise guide holes, wherein the guide holes are respectively arranged through the interior of the gear, wherein reinforcing plates are respectively installed inside the guide holes, wherein a plurality of heat-conducting tubes are respectively movably installed between the guide holes and the reinforcing plates, wherein a plurality of heat-conducting plates are respectively installed outside the heat-conducting tubes, and wherein the heat-conducting plates are respectively movably installed between the guide holes and the reinforcing plates.

[0006] Preferably, the guide hole is arranged to be inclined, and the guide hole is semi-arc-shaped.

[0007] Preferably, a plurality of guide grooves are respectively provided inside the guide holes, and a plurality of reinforcing rods are fixedly installed between the guide grooves and the reinforcing plates.

[0008] Preferably, the heat-conducting tubes are movably installed through the outside of the rod body of the reinforcing rod.

[0009] Preferably, limit plates are fixedly mounted on both ends of the rod body of the reinforcing rod, and the limit plates are in close contact with the heat conducting tube.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] (1) In the utility model, during the rotation of the gears, the lubricating oil and air inside the gearbox can flow through the guide holes, thereby increasing the contact area between the lubricating oil, the air and the gears and improving the heat dissipation efficiency. At the same time, the reinforcing plates and reinforcing rods in the guide holes can increase the overall strength and rigidity of the gears, so that the gears can always maintain a stable state during operation.

[0012] (2) In the utility model, when wind or lubricating oil flows in the guide hole, the wind or lubricating oil contacts the heat-conducting tube and the heat-conducting plate, thereby further improving the heat dissipation efficiency of the lubricating oil and wind on the gear, reducing the heat of the gear and extending its service life. At the same time, through the positioning of the limit plate, the collision between the heat-conducting plate and the guide hole and the reinforcing plate is avoided, thereby better protecting them.

[0019] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, an embodiment of the utility model proposes a transmission power output gear, including a gear 1, a plurality of auxiliary mechanisms 2 are arranged inside the gear 1, the auxiliary mechanisms 2 include guide holes 201, the guide holes 201 are respectively penetrated through the interior of the gear 1, reinforcing plates 202 are respectively installed inside the guide holes 201, a plurality of heat-conducting tubes 206 are respectively movably installed between the guide holes 201 and the reinforcing plates 202, a plurality of heat-conducting plates 207 are respectively installed on the outer sides of the heat-conducting tubes 206, and the heat-conducting plates 207 are respectively movably installed between the guide holes 201 and the reinforcing plates 202.

[0021] like Figure 2 and Figure 5 As shown, in another embodiment of the utility model, the guide hole 201 is set to be inclined, and the guide hole 201 is semi-arc-shaped, and a plurality of guide grooves 203 are respectively provided inside the guide hole 201, and a plurality of reinforcing rods 204 are fixedly installed between the guide grooves 203 and the reinforcing plate 202, and the heat-conducting tube 206 is movably installed through the outside of the rod body of the reinforcing rod 204, and the limiting plates 205 are respectively fixedly installed at both ends of the rod body of the reinforcing rod 204, and the limiting plates 205 are fitted with the heat-conducting tube 206.

[0022] When the gear 1 rotates, if the lower half of the gear 1 can be immersed in the lubricating oil, as the gear 1 rotates, when the guide hole 201 enters the lubricating oil, the lubricating oil can flow along the inside of the guide hole 201 to increase the contact area between the lubricating oil and the gear 1, and can push the heat-conducting tube 206 and the heat-conducting plate 207 to rotate, so as to further increase the contact area between the lubricating oil and the heat-conducting tube 206 and the heat-conducting plate 207, and improve the heat dissipation efficiency. Then, when the guide hole 201 is separated from the lubricating oil, the inclined guide hole 201 allows the air to flow into the inside of the guide hole 201 along the lower end of the guide hole 201, thereby increasing the contact area between the air and the gear 1, allowing the air to continuously flow inside the guide hole 201, so as to perform dual heat dissipation through the lubricating oil and the air.

[0023] When the gear 1 rotates, if the gear 1 cannot be immersed in the lubricating oil and can only dissipate heat through the lubricating oil splashed during the rotation, the heat can be dissipated through the cooperation of air and the guide hole 201. Although it is not as good as the dual heat dissipation of lubricating oil and air, it can also reduce the temperature of the gear 1 and extend the service life of the gear 1.

[0024] The reinforcing plate 202 and the reinforcing rod 204 are used to increase the overall strength and rigidity of the gear 1 , which can cooperate with the guide hole 201 to assist the gear 1 in heat dissipation and also enable the gear 1 to transmit power more stably.

[0025] The working principle of the power output gear of this gearbox:

[0026] When in use, first, when the gear 1 rotates, if the lower half of the gear 1 can be immersed in the lubricating oil, as the gear 1 rotates, when the guide hole 201 enters the lubricating oil, the lubricating oil can flow along the inside of the guide hole 201 to increase the contact area between the lubricating oil and the gear 1, and can push the heat-conducting tube 206 and the heat-conducting plate 207 to rotate, so as to further increase the contact area between the lubricating oil and the heat-conducting tube 206 and the heat-conducting plate 207, and improve the heat dissipation efficiency. Then, when the guide hole 201 is separated from the lubricating oil, the inclined guide hole 201 allows air to flow into the inside of the guide hole 201 along the lower end of the guide hole 201, thereby increasing the contact area between the air and the gear 1, allowing the air to continuously flow inside the guide hole 201, so as to perform dual heat dissipation through the lubricating oil and the air.

[0027] When the gear 1 rotates, if the gear 1 cannot be immersed in the lubricating oil and can only dissipate heat through the lubricating oil splashed during the rotation, the heat can be dissipated through the cooperation of air and the guide hole 201. Although it is not as good as the dual heat dissipation of lubricating oil and air, it can also reduce the temperature of the gear 1.

[0028] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
