AI Technical Summary
When the gear box is working, the exhaust structure causes oil to emerge, and the prior art is difficult to effectively control the amount of oil overflow.
The inclined surface around the exhaust port and the boss on the bottom surface of the exhaust port are designed to be straight planes, and the edges of the boss on the bottom surface of the exhaust port are not chamfered. The exhaust port structure is optimized to reduce the splash and siphoning of oil.
It effectively reduces the amount of oil coming out of the exhaust port during operation of the gearbox, and reduces the accumulation and overflow of oil.

Abstract
Description
Technical Field
[0001] The utility model relates to a gear box, in particular to an exhaust structure of the gear box. Background Art
[0002] When the gearbox is working, the gears inside rotate at high speed, and the friction between them will generate a lot of heat, causing the air inside the gearbox to expand due to the heat. Therefore, the gearbox needs to be designed with an exhaust structure to balance the pressure of the gas inside and outside the gearbox, but this will cause the oil inside the gearbox to escape along with the exhaust structure. Utility Model Content
[0003] The utility model provides a gear box exhaust structure, which aims to reduce the amount of oil escaping through the exhaust port when the gear box is working.
[0004] The utility model is realized by the following technical solutions:
[0005] A gearbox exhaust structure includes an exhaust port bottom boss, the exhaust port is located in the center of the exhaust port bottom boss, an inclined surface is designed around the exhaust port, the exhaust port bottom boss is a straight plane, and the boss edge is not chamfered.
[0006] The bevel angle is 3-5°.
[0007] The utility model can greatly reduce the amount of oil escaping through the exhaust port when the gear box is running. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is a schematic structural diagram of the utility model. DETAILED DESCRIPTION
[0009] like Figure 1 As shown, the gearbox exhaust structure described in the present invention reduces the amount of oil emerging through the exhaust port by optimizing and improving the structural design around the exhaust port. During the operation of the gearbox, the splashed oil falls around the exhaust port 1. The exhaust port is designed to be surrounded by a slope 2, which makes it easier for the oil attached to it to slide down, thereby preventing a large amount of oil from accumulating at the exhaust port and emerging through the exhaust port. For the oil splashed on the boss 3 on the bottom surface of the exhaust port, this structure designs the bottom boss as a straight plane, and the edge of the boss is not chamfered, which reduces the siphon effect at the edge of the bottom surface of the exhaust port during the exhaust process and effectively reduces the amount of oil emerging from the exhaust port.
