Utility model content
The purpose of this utility model is in that to provide one can reduce noise, improves the Novel conjoined of air-out efficiency and determines shell component after impeller and motor.
For realizing above-mentioned utility model purpose, this utility model provides a kind of Novel conjoined and determines impeller, including substrate, the locating dowel being arranged on position, described substrate axle center, and it is arranged on the guide vane group of described substrate peripheral, described locating dowel exceeds described substrate to side projection, and is internally provided with the chamber of location bearing；Described guide vane group is provided with positioned fastener.
As further improvement of the utility model, described locating dowel includes the installing hole be located at both sides end face and be connected with described chamber, described installing hole includes the first axially disposed installing hole and the second installing hole, and the diameter of described first installing hole is less than the diameter of described second installing hole.
As further improvement of the utility model, described guide vane group includes the some guide vanes arranged in the axial direction in two rows, and the two some described guide vanes of row are helically extended, and the spiral extension direction of the two some described guide vanes of row is contrary in a circumferential direction.
As further improvement of the utility model, described positioned fastener includes keeper and securing member, and described keeper protrudes setting outwardly from the top of described guide vane, and described securing member caves inward from described guide vane top setting.
As further improvement of the utility model, between lateral surface and the end face of described substrate of described locating dowel, it is provided with reinforcement.
For achieving the above object, this utility model also provides for shell component after a kind of motor, and including housing and be arranged on the described above conjuncted of described housing side and determine impeller, described housing is provided with the through hole relative with the described conjuncted positioned fastener determined on impeller.
The beneficial effects of the utility model are: this utility model motor is provided by including the conjuncted rear shell component determining impeller and housing, and determine impeller is provided with locating dowel described, for positioning bearing and rotating shaft, from without determining to arrange between impeller and housing retort stand, there is the noise reducing motor, improve the efficiency of air inlet/outlet, the advantage reducing production cost.
Accompanying drawing explanation
