Abstract
It the utility model is related to motor, specially air water cooling high-power coal cutter motor.Solve that the existing coal-winning machine motor type of cooling is unreasonable, thus the design and manufacture to high-power coal cutter motor form the problem of restricting.The air water cooling high-power coal cutter motor includes water cooling casing, stator, rotor and end cap；Air vent is evenly equipped with rotor punching, so as to form axial ventilation hole in rotor core, the ventilating air passage that both ends communicate with the inner chamber of water cooling casing is provided between the circulation waterway of water cooling casing and outer surface, one end of rotor shaft is fixed with fan.So, compulsory circulative cooling wind path is formed under fan effect.The utility model is on the basis of the existing water cooling casing of coal-winning machine motor, compulsory circulative cooling wind path is formd in motor again, the heat on rotor is set to be delivered to faster on the water route of water cooling casing, rotor temperature rise is effectively reduced, favourable condition is provided for more powerful coal-winning machine design of electrical motor.
Description
Technical field
It the utility model is related to motor, specially air water cooling high-power coal cutter motor.
Background technology
Coal-winning machine is one and integrates machinery, electric and hydraulic pressure large-scale complicated system.Winning machine cutting part flame proof
The characteristics of type threephase asynchronous：Small volume, in light weight, noise is small, good dustproof effect；Electrical appliance part has necessarily explosion-proof
Performance.
The existing coal-winning machine motor type of cooling is casing water cooling, and heat caused by rotor, stator is by radiating and conducting
Mode is transferred in water route, then cooled water is taken away.The mode of heat radiation and heat transfer determines the heat of coal-winning machine motor internal
In the recirculated water being transferred in water route that amount can not be rapidly and efficiently；This coal-winning machine design of electrical motor system big to high-power, caloric value
Appearance is into restriction.
The content of the invention
The existing coal-winning machine motor type of cooling of the utility model solution is unreasonable, thus high-power coal cutter motor is set
Meter manufacture forms the problem of restricting, there is provided a kind of air water cooling high-power coal cutter motor.
The utility model adopts the following technical scheme that realization：Air water cooling high-power coal cutter motor, including water cooling unit
Shell, stator, rotor and end cap；Air vent is evenly equipped with rotor punching, so as to form axial ventilation hole on rotor core,
The ventilating air passage that both ends communicate with the inner chamber of water cooling casing, rotor shaft are provided between the circulation waterway of water cooling casing and outer surface
One end be fixed with fan.So, compulsory circulative cooling wind path is formed under fan effect, i.e., the wind of fan blowout is through rotor iron
Air vent on core, enter ventilating air passage from one end of ventilating air passage, sucked after being come out from the ventilating air passage other end by fan.
The utility model is on the basis of the existing water cooling casing of coal-winning machine motor, and to form forced circulation cold again in motor
But wind path, the heat on rotor is delivered to faster on the water route of water cooling casing, be effectively reduced rotor temperature rise, be bigger work(
The coal-winning machine design of electrical motor of rate provides favourable condition.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- water cooling casings, 2- end caps, 3- air vents, 4- ventilating air passages, 5- fans, 6- cooling air ducts.
Embodiment
Air water cooling high-power coal cutter motor, including water cooling casing 1, stator, rotor and end cap 2；On rotor punching
Air vent is furnished with, so as to form axial ventilation hole 3 on rotor core, between the circulation waterway of water cooling casing 1 and outer surface
The ventilating air passage 4 communicated provided with both ends with the inner chamber of water cooling casing, one end of rotor shaft is fixed with fan 5, so, in fan
Compulsory circulative cooling wind path 6 is formed under effect, i.e., the wind that fan 5 is blown out is through the air vent 3 on rotor core, from ventilating air passage 4
One end enter ventilating air passage, sucked after being come out from the ventilating air passage other end by fan.Further to reduce temperature rise, so as to have more
High power ascension space, water-cooling structure also is provided with end cap 2；The circulation waterway of end cap 2 and water cooling casing 1 is sealed with water pipe to be connected
Pick up and, ensure the unification of circulation waterway, unimpeded and seal.
Claims (3)
1. a kind of air water cooling high-power coal cutter motor, including water cooling casing（1）, stator, rotor and end cap（2）；Its feature exists
In being evenly equipped with air vent on rotor punching, so as to form axial ventilation hole on rotor core（3）, in water cooling casing（1）'s
The ventilating air passage that both ends communicate with the inner chamber of water cooling casing is provided between circulation waterway and outer surface（4）, one end of rotor shaft
It is fixed with fan（5）, so, compulsory circulative cooling wind path is formed under fan effect（6）.
2. air water cooling high-power coal cutter motor according to claim 1, it is characterised in that end cap（2）On also be provided with water cooling
Structure.
3. air water cooling high-power coal cutter motor according to claim 2, it is characterised in that end cap（2）With water cooling casing
（1）Circulation waterway be sealedly connected with water pipe.
