The rotor cooling of existing high-speed electric expreess locomotive is general adopts air-cooled and liquid cooling mode, adopt the high-speed electric expreess locomotive power consumption of air cooling way larger, liquid cooling mode can make cooling fluid can splash away from rotor surface, all be cooled liquid and steam of all parts of motor internal infiltrates, so the insulation of part in motor, resist chemical, anti-corrosion require all very high, casing also must be accomplished airtight.
Therefore, necessary the deficiency solving prior art is improved to prior art.
Utility model content:
The utility model is the cooling structure providing a kind of high speed rotor of motor in order to solve above-mentioned prior art Problems existing.
The technical scheme that the utility model adopts has: a kind of cooling structure of high speed rotor of motor, comprise casing, stators and rotators, described stator is placed in casing, rotor turns is located at stator) in, also comprise recovery tank, backwater tank tower, water inlet pipe, admitting pipe joint, outlet pipe and sealing shroud, recovery tank is fixedly connected with backwater tank tower, backwater tank tower is sealedly connected on the bottom of casing, the lower end of described rotor stretches in recovery tank through backwater tank tower, axis direction along rotor is provided with Cooling Holes, water inlet pipe is placed in this Cooling Holes, and the lower end of water inlet pipe stretches in, and recovery tank is interior to be connected with admitting pipe joint, admitting pipe joint and outlet pipe are connected on recovery tank, described sealing shroud is set in the junction of rotor and backwater tank tower.
Further, described sealing shroud has the body of a tubulose, the bottom of this body stretches out the sealing of formation one platform-like, in sealing portion concentric be provided with the first O-ring boss and the second O-ring boss, be formed with the first seal groove between the first O-ring boss and the second O-ring boss.
Further, on described backwater tank tower concentric be provided with the 3rd O-ring boss and the 4th O-ring boss, be formed with the second seal groove between the 3rd O-ring boss and the 4th O-ring boss.
The utility model has following beneficial effect: the rotor good cooling results of the utility model structure, and structure is simple, easily manufactured, is convenient to handling, good sealing effect.
Accompanying drawing illustrates:
Fig. 1 is the utility model structure chart.
