Description

[0003] Existing gear casting boxes are often re-optimized and redesigned by increasing the wall thickness of the casting and adding reinforcements to the upper and lower box structures of the gear box. When new materials and manufacturing methods are used, the corresponding strength requirements can be met. However, there are the following defects: when the gear box is running under high load, the gears will generate a lot of heat. The gear box is prone to deformation in a high temperature environment, causing damage to the gear box; oil immersion lubrication can allow the heat of the gear to be transferred to the lubricating oil when used for a short period of time, but for a gear box that is used for a long time, it will still generate heat accumulation.
