Abstract
The utility model relates to the field of manufacture of motors and discloses an external heat dissipation device of a motor bearing. The external heat dissipation device of the motor bearing comprises an end cover and a rotating shaft of a motor and a sliding ring chamber and is characterized in that a fan is arranged on the rotating shaft of the motor; the fan is positioned between the end cover of the motor and the sliding ring chamber; an internal air outlet and an external air inlet are arranged in the axial direction of the sliding ring chamber; a wind guide cylinder is arranged between the end cover and the sliding ring chamber; the fan is positioned in the wind guide cylinder; and an exhaust hole is arranged in the tangent direction of the wind guide cylinder. The external heat dissipation device of the motor bearing disclosed by the utility model is simple in structure and is capable of increasing the heat dissipation effect of the bearing and reducing the use amount of a heat dissipation material and the cost.
Description
Technical field
The utility model relates to field of motor manufacturing, the outer heat abstractor of particularly a kind of motor bearings.
Background technology
Generally speaking, the natural cooling mode is adopted in the heat radiation of motor.During for the further cooling of bearing, realize, but this bearing type of cooling waste material is low to the utilance of heat sink material weak effect through radiating ribs additional on end cap.Have the motor of slip ring chamber for air cooling wind-driven generator etc., because of the slip ring chamber near end cap, the radiating effect of its bearing is poorer.
Summary of the invention
To above-mentioned technical problem, the purpose of the utility model is to provide a kind of motor bearings outer heat abstractor, can make the motor with slip ring chamber improve the bearing radiating effect, reduces the use amount of heat sink material, reduces cost.
In order to achieve the above object, the utility model adopts following technical scheme to be achieved.
A kind of motor bearings is heat abstractor outward, comprises end cap, rotating shaft and the slip ring chamber of motor, it is characterized in that the rotating shaft of motor is provided with fan, and fan is between the end cap and slip ring chamber of motor.
The characteristics of technique scheme are with further improving:
Said slip ring chamber axially be provided with inboard air outlet and outside air inlet.
Be provided with ventilating duct between said end cap and the slip ring chamber, fan is positioned at ventilating duct, and the ventilating duct tangential is provided with exhaust outlet.
In the utility model; The rotating shaft of motor is provided with fan; Fan between the end cap and slip ring chamber of motor, the slip ring chamber axially be provided with inboard air outlet and outside air inlet, between end cap and slip ring chamber, be provided with ventilating duct; Fan is positioned at ventilating duct, and ventilating duct is cut and is provided with exhaust outlet.Fan sucks wind through mechanical rotation from the slip ring chamber; And in Radial Flow, the ventilating duct that is provided with between end cap and the slip ring chamber plays rectified action to wind, makes wind energy enough change direction and flows to end cap; And take away the heat of bearing, the exhaust outlet that is provided with through tangential, ventilating duct bottom at last gets in the atmosphere.The utility model is simple in structure, can improve the bearing radiating effect, reduces the use amount of heat sink material, reduces cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Fig. 1 is the structural representation of the outer heat abstractor of a kind of motor bearings of the utility model;
Among the figure: 1, rotating shaft; 2, end cap; 3, slip ring chamber; 4, fan; 5, ventilating duct; 6, exhaust outlet.
Embodiment
With reference to Fig. 1, for the outer heat abstractor of a kind of motor bearings of the utility model, be specially the air cooling wind-driven generator, fan 4 is installed in the rotating shaft 1 of motor, fan 4 is between the end cap 2 and slip ring chamber 3 of motor; Between end cap 2 and slip ring chamber 3, be provided with ventilating duct 5, fan 4 is positioned at ventilating duct 5, and the tangential, bottom of ventilating duct 5 is provided with exhaust outlet 6.Axially be provided with inboard air outlet and outside air inlet in slip ring chamber 3.Slip ring chamber 3 outside air inlets can be mesh.When motor rotation, rotating shaft 1 drives fan 4 rotations, and 3 outside air inlets get into wind outside from the slip ring chamber, the 3 inboard air outlet suction fans 4 through the slip ring chamber, and cooling end cap 2 is discharged after taking away the heat of bearing.Another characteristics of the utility model also are, can clean slip ring chamber 3 environment, reduce the slip ring failure rate.
Although more than combine accompanying drawing that the embodiment of the utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protected, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
