Description
Technical Field
The utility model relates to a motor heat dissipation technical field, concretely relates to air-cooled motor.
Background
The air cooling motor is widely applied to various fields to provide driving force for various mechanical equipment, and the air cooling motor which is most commonly used in the prior art comprises a shell, wherein the front end of the shell is connected with a front cover body. The rear end is connected with the back lid to form the chamber that holds that is used for holding stator and rotor, the cover is equipped with the cover body on the back lid, and the internal centrifugal fan and the centrifugal fan that are provided with of cover are connected with the rotor, and wind blows to the casing outer wall all around from the inside of the cover body, and the heat on the heat dissipation muscle is taken away to the air current, thereby improves the heat dispersion of motor. However, in some special environments, for example, when the temperature of the device connected to the front bearing of the motor is high, the front bearing of the motor may work in a high temperature environment, the high temperature may be directly conducted to the motor through the rotating shaft of the motor, and may affect the motor bearing and the motor winding, and the bearing or the winding may be burnt due to the high temperature.
In order to solve the above problems, a utility model patent entitled "motor front axle cooling device" (granted publication No. CN211630021U) discloses the following technical solutions: including the direction of blowing for the motor rear end fan from motor rear end to motor front end, motor rear end fan casing encloses and closes motor rear end fan, and the air outlet of motor rear end fan casing links up in the tip of motor fin, increases a wind scooper at the motor front end, and the air current that will blow to from the motor rear end leads motor front end bearing department, dispels the heat to the front end bearing, simple structure, simple to operate. However, the temperature of the air flow blown from the rear end of the motor is already raised due to the heat inside the motor, and the heat of the front bearing of the motor cannot be effectively dissipated.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a motor shaft front end is in high temperature environment, and the motor can continuous use and safe and reliable's forced air cooling motor.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides an air-cooled motor, includes casing and the stator that sets up in the casing, and the stator internal rotation is provided with rotor, its characterized in that: the front end rotating shaft of the rotor protrudes to the outside of the shell, the front end rotating shaft is fixedly connected with a fan, the fan is coaxially sleeved on the front end rotating shaft, and the front end rotating shaft and the fan synchronously rotate.
In the above-mentioned scheme, directly set up the fan in front end pivot department and directly blow cooling to the front end pivot, the cooling effect is good to guarantee that the motor can continuous use and safe and reliable, simultaneously because fan fixed connection is in the front end pivot, when the front end pivot rotated, the fan just can rotate thereupon, so need not be equipped with extra power supply, the cost is lower and performance is good.

Detailed Description
As shown in fig. 1-3, an air-cooled motor includes a housing 10 and a stator disposed in the housing 10, wherein a rotor is rotatably disposed in the stator, a front-end rotating shaft 20 of the rotor protrudes out of the housing 10, and a fan 30 is fixedly connected to the front-end rotating shaft 20, and the fan 30 is coaxially sleeved on the front-end rotating shaft 20 and rotates synchronously with the front-end rotating shaft 20. Utilize the spatial position of casing 10, directly set up fan 30 in front end pivot 20 department and directly blow the cooling to front end pivot 20, the cooling effect is good to guarantee that the motor can continuous use and safe and reliable, simultaneously because fan 30 fixed connection is on front end pivot 20, when front end pivot 20 rotated, fan 30 just can rotate along with it, so need not be equipped with extra power supply, the cost is lower and performance is good.
In order to further improve the heat dissipation effect, a plurality of heat dissipation columns 11 are uniformly arranged on the front end cover of the housing 10 at intervals along the circumferential direction of the front end cover, the length direction of the heat dissipation columns 11 is parallel to the axial direction of the front end rotating shaft 20, the fan 30 is located in a cylindrical area enclosed by the heat dissipation columns 11, and meanwhile, the hollow areas among the heat dissipation columns 11 do not influence the air inlet and outlet.
The heat dissipation column 11 is wrapped with the heat-conducting fins 12, so that the heat dissipation column 11 can be effectively utilized to enhance the heat dissipation of the front end of the motor, and the heat transfer from the shaft end to the inside of the motor is reduced.
The rear end of the heat dissipation column 11 is welded with the front end cover of the shell 10, the front end of the heat dissipation column is fixedly connected with the flange plate 13, the flange plate 13 is fixedly connected onto the motor mounting plate 40 through the bolts 14, through holes for the front end rotating shaft 20 to pass through are formed in the middle of the flange plate 13 and the motor mounting plate 40, the fan 30 is installed in the space between the flange plate 13 and the front end of the motor, and the arrangement of the motor cannot be influenced.
