Abstract

The invention discloses a drive motor heat-dissipation device for a mining electric locomotive, and the device comprises a heat-dissipation device housing, gears, transmission shafts, rolling bearings, fan blades, and a rack. A drive motor is disposed in the heat-dissipation device housing, and a drive motor output shaft is provided with the drive motor, the first gear and the first rolling bearing from the left to the right. The first transmission shaft is connected with the third rolling bearing, the third gear, the second gear and the second rolling bearing from the left to the right. The second transmission shaft is provided with the fourth rolling bearing, the fourth gear, the fifth rolling bearing and the fan blades from the left to the right. The first gear is engaged with the second gear, and the third gear is engaged with the fourth gear. The device can be suitable for an occasion with the high gas density, cannot generate a large amount of heat after long-time operation, and can save the electric energy.

Description

technical field

[0001] The invention relates to a cooling device for a driving motor of a mining electric locomotive. Background technique

[0002] The working environment of mining electric locomotives is generally complex and chaotic, and the environment is underground with poor ventilation. In order to improve industrial efficiency and work progress, overloading often occurs, which will cause the temperature of the drive motor to rise. When it is overheated, it will seriously affect the service life of the electric locomotive. A common solution is to use a blower to dissipate heat from the drive motor, but there are some drawbacks in this way. One is that the blower is driven by electric energy, so the gas concentration in the mine must be taken into account, and explosion-proof measures need to be added. The 2nd, blower also utilizes electric motor to work, also can generate heat, can't carry out long-time work. Contents of the invention
