Abstract
The utility model relates to a variable speed cooling fan of a motor. The variable speed cooling fan of the motor comprises a baffle, a large spline, a large fan body, a push sleeve, a motor box, a small fan body, a small spline, a spline shaft and a spring. The variable speed cooling fan is provided with the spline shaft matched with the motor, the top of the spline shaft is provided with the baffle, the front portion of a shaft body of the spline shaft is provided with the large spline, the tail portion of the shaft body is provided with the small spline, the small spline on the tail portion of the spline shaft is sequentially provided with the small fan body, the push sleeve and the large fan body, the small fan body and the push sleeve are respectively provided with a spline groove matched with the small spline, the large fan body is provided with a spline groove matched with the large spline on the front portion of the spline shaft, and the spline shaft between the baffle at the top of the spline shaft and the large fan body is sleeved with the spring capable of sliding freely. The variable speed cooling fan of the motor is provided with the two fan bodies, so that the air speed can be improved and the effect of strong cooling is achieved.
Description
Technical field
The utility model relates to a kind of motor ventilating fan for cooling, especially a kind ofly can change speed, makes a kind of electrical motor gearshift cooling fan that wind speed is stronger.
Background technique
At present, general motor only is provided with a fan, when motor works long hours, can not reach better in time cooling-down effect.
Summary of the invention
In order to solve the bad shortcoming of electric motor temperature reduction effect, the utility model provides a kind of electrical motor gearshift cooling fan, and this electrical motor gearshift cooling fan is provided with two fan heads, can improve wind speed, reaches the effect of powerful cooling.
The utility model solves the technological scheme that its technical problem adopts: this electrical motor gearshift cooling fan comprises: baffle plate, large spline, big fan, pushing set, motor housing, small fan, little spline, splined shaft, spring; This electrical motor gearshift cooling fan is provided with the splined shaft with the motor coupling, the splined shaft top is baffled, large spline is established in splined shaft axle body front portion, afterbody is established little spline, be sequentially with small fan, pushing set, big fan on the little spline of splined shaft afterbody, small fan and pushing set all are provided with the spline with little spline joint match, and small fan and pushing set can be slided and rotate with splined shaft before and after little spline simultaneously; Big fan is provided with the match spline of coupling of large spline with the splined shaft front portion, big fan can along slide before and after splined shaft and simultaneously on large spline along with splined shaft rotates; On the baffle plate on splined shaft top and the splined shaft between big fan, cover has the spring be free to slide, in order to retrain the slip of big fan.After the motor slow start, only have small fan to rotate with splined shaft, after the motor high speed rotating, impel big fan to slide to the right until large splined section, the spline of big fan is with after large spline joint match is connected, and big fan rotates with splined shaft, be subject to the constraint of spring simultaneously after slip no longer to the right only rotated, large small fan rotates simultaneously, just reaches the effect that wind-force is strengthened.
The beneficial effects of the utility model are: this electrical motor gearshift cooling fan is provided with two fan heads, can improve wind speed, reaches the effect of powerful cooling.
