Description

Technical Field

[0001] The utility model relates to the technical field of wind power gear box cooling devices, in particular to a detachable wind power gear box cooling device. Background Art

[0002] The wind turbine gearbox is an important component of the wind power generation system. Its main function is to convert the power of wind into electrical energy. It is located at the forefront of the wind power generation system and is a bridge connecting the wind wheel and the generator. During the wind power generation process, the gearbox will increase in temperature due to friction, heat and other factors. Overheating inside the gearbox will increase the thermal expansion of the metal material, thereby increasing the friction and wear between the various components of the gearbox. At the same time, an overheated gearbox will cause the speed to drop, thereby reducing the power generation. The high temperature environment will accelerate the fatigue damage and failure of the metal material, increase its maintenance cost, shorten its service life, and also cause equipment failure, affecting normal power supply. Therefore, in order to ensure the normal operation and extend the service life of the wind turbine gearbox, effective cooling measures must be taken to prevent overheating.

[0003] The cooling of wind turbine gearboxes includes air cooling and water cooling. However, the existing cooling devices and gearboxes are mostly integrated structures. When the cooling device is damaged, the gearbox needs to be disassembled as a whole, which has a high maintenance cost. It also increases the workload of cooling device maintenance and causes inconvenience to the maintenance process.

[0026] In this embodiment, during assembly, the cooling plate 203 is first clamped on the inner side of the cooling box 202, and then the two groups of cooling boxes 202 are fixed in the two groups of slots 201 at the outer end of the gear housing 1 using bolts.
