Abstract

The invention discloses a motor heat dissipation device of an electric locomotive. The motor heat dissipation device comprises a cooling device shell, a gear, a transmission shaft, a rolling bearing,fan blades and a rack. The driving motor is installed in the heat dissipation device shell. A driving motor, a first gear and a first rolling bearing are respectively mounted on the output main shaftof the driving motor from left to right; the first transmission shaft is connected with a third rolling bearing, a third gear, a second gear and a second rolling bearing from left to right, the secondtransmission shaft is provided with a fourth rolling bearing, a fourth gear, a fifth rolling bearing and fan blades from left to right, the first gear is meshed with the second gear, and the third gear is meshed with the fourth gear. The device can be suitable for occasions with high gas concentration and can work for a long time without generating a large amount of heat and can save electric energy.

Description

technical field [0001] The invention relates to a cooling device for a motor of an 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 [0003] The object of the present invent...
