Description

Technical Field

[0002] At present, in order to facilitate the motor to better achieve the transmission purpose, a gearbox will be equipped for the motor. The gearbox has a wide range of applications. For example, in the application of wind power generation sets, the gearbox is an important mechanical component widely used in wind power generation sets. Its main function is to transmit the power generated by the wind wheel under the action of wind force to the generator and make it obtain the corresponding rotation speed. Usually, the rotation speed of the wind wheel is very low, far from reaching the rotation speed required for the generator to generate electricity. It must be achieved through the speed-increasing effect of the gear pair in the gearbox. Therefore, the gearbox is also called a speed-increasing box.

[0003] At present, some motor gearboxes can achieve the purpose of steering and changing the rotation speed. Due to the meshing of the gears inside the gearbox, a large amount of heat will be generated during the rotation of the gears. In order to dissipate heat, the existing motor gearboxes mostly use external heat dissipation methods for heat dissipation, and the overall heat dissipation efficiency is average. For this reason, we propose a heat dissipation device and its motor gearbox. Content of the Utility Model
