Description

Technical Field

[0001] The utility model relates to the technical field of inner oil hole gear heat dissipation, in particular to an inner oil channel heat dissipation gear. Background Art

[0002] The reduction box is also called a speed reducer or a reducer. It works on the principle that the prime mover is connected to the reduction box, and the reduction box is then connected to the working machine. It is a power transmission device. The function of the reduction box is mainly to use a multi-stage gear structure to reduce the output of the motor or increase the output of the motor. When there is a reduction transmission, the prime mover provides high-speed, low-torque power. Conversely, when there is a speed increase transmission, the prime mover provides low-speed, high-torque power. In mechanical transmission, the reduction box needs to drive its working object - the working machine to achieve the predetermined purpose.

[0003] Existing reducers basically lubricate gears by oil immersion lubrication. The lubricating oil not only protects the gears, but also helps the gears dissipate heat. However, the existing reducer gears generally use lubrication and heat exchange by immersion in lubricating oil. This method requires a large amount of oil to be filled in the reducer, and the reducer needs to be thermally treated in a low temperature environment to ensure that the oil can be evenly wrapped during the rotation of the gears. The oil only exchanges heat through contact with the gear surface, and the cooling effect is low, which has certain defects. For this reason, we propose an internal oil channel heat dissipation gear.

[0024] The following will be combined with the drawings in 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 in 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.

[0025] See also Figure 1-4 In this embodiment, an inner oil channel heat dissipation gear comprises a gear body 100, a heat dissipation roller 110 is movably connected inside the gear body 100, an evacuation hole 120 is opened at the bottom of the gear body 100, and an oil-repellent component 200 is fixedly connected inside the gear body 100;

[0026] The oil-repellent assembly 200 includes an oil-repellent chamber 210, to which the gear body 100 is fixedly connected, a movable groove 220 is provided inside the oil-repellent chamber 210, a centrifugal ball 230 is movably connected inside the movable groove 220, an auxiliary ball 240 is movably connected to the outer surface of the centrifugal ball 230, and oil inlet holes 250 are provided at the top and bottom of the oil-repellent chamber 210.

[0027] When implementing it, Figure 3 to Figure 4 As shown, an oil drain hole is opened on the outside of the oil drain tank 210, and the oil drain hole is connected with the evacuation hole 120 through the oil drain tank 210, the gear body 100, so that the oil inside the oil drain tank 210 can be transported to the surface of the gear body 100, so that the gear body 100 and other gears do not affect the meshing, while ensuring the smoothness of the rotation between the gears.

[0028] like Figure 2As shown, the movable groove 220 is connected to the oil hole 320 through the oil drain tank 210. Therefore, when the gear body 100 is running, the oil inside the oil drain tank 210 can be guided to the inside of the oil hole 320 through the relative rolling effect between the centrifugal balls 230 and the auxiliary balls 240 inside the movable groove 220.

[0029] like Figure 4 As shown, the shaft column 410 is connected to the gear body 100 through the connecting rib 330, the turbine disk 310, and the oil trap 210. The outer side of the connecting hole 420 is fixedly connected with the connecting rib 330. When the gear body 100 is running, the connecting hole 420 can transfer the heat inside the shaft hole 430 to the connecting rib 330, and then disperse it through the heat dissipation blades 340.

[0030] In summary, the inner oil channel heat dissipation gear is provided with an oil-repellent component 200, so that in daily use of the gear body 100, when the lubricating oil enters the oil-repellent chamber 210, the lubricating oil can be evenly diffused to other components through the linkage design of the centrifugal ball 230 and the auxiliary ball 240, thereby enhancing the lubricating oil infiltration efficiency. At the same time, when the gear rotates at high speed, the balls roll relatively inside the oil-repellent chamber 210, which can disperse the heat.

[0031] Furthermore, by providing the heat dissipation blades 340 and the heat dissipation rollers 110, when the gear body 100 rotates at a high speed, frictional heat is generated between the gears, which in turn drives the heat dissipation rollers 110 to rotate inside the gear body 100, thereby minimizing the surface wear of the gear body 100 and extending the service life of the gear body 100. At the same time, good heat dissipation can be maintained, thereby reducing the temperature of the tooth surface of the meshing gears and eliminating the heat inside the gears.
