JP-A-6-299992

従来のファンロータは、複数の羽根を支持円板に順次取り付けるので、支持円板の中心に重心を一致させて組み立てるのが困難である。
そして、支持円板の中心に重心が一致していないと、ファンロータのバランス精度が悪く、ファンロータの回転時の抵抗が大きくなる。
In the conventional fan rotor, since a plurality of blades are sequentially attached to the support disk, it is difficult to assemble with the center of gravity coincident with the center of the support disk.
If the center of gravity does not coincide with the center of the support disc, the balance accuracy of the fan rotor is poor, and the resistance during rotation of the fan rotor increases.

この発明は、上記したような不都合を解消するためになされたもので、支持円板の中心に重心を一致させて複数の羽根を容易に組み立てることができ、回転時の抵抗を小さくすることのできるファンロータを提供するものである。   The present invention has been made to eliminate the above-described disadvantages, and can make it easy to assemble a plurality of blades by making the center of gravity coincide with the center of the support disk, and reduce resistance during rotation. The present invention provides a fan rotor that can be used.

この発明は、以下のような発明である。
(1)支持円板と支持リング板との間に複数の羽根を配設したファンロータにおいて、前記複数の羽根を、連結支持板部に連設させて連結したことを特徴とする。
(2)(1)のファンロータにおいて、前記連結支持板部および前記複数の羽根は、一枚の金属板にせん断加工および曲げ加工を施すことによって形成したことを特徴とする。
(3)(1)または(2)に記載のファンロータにおいて、前記支持円板の外周縁および前記支持リング板の外周縁にヘミング曲げ加工またはカーリング加工を施したことを特徴とする。
The present invention is as follows.
(1) In a fan rotor in which a plurality of blades are disposed between a support disc and a support ring plate, the plurality of blades are connected to and connected to a connection support plate portion.
(2) In the fan rotor of (1), the connection support plate portion and the plurality of blades are formed by subjecting one metal plate to shearing and bending.
(3) In the fan rotor described in (1) or (2), a hemming bending process or a curling process is performed on the outer peripheral edge of the support disk and the outer peripheral edge of the support ring plate.

この発明によれば、複数の羽根を連結支持板部に連設させて連結したので、連結支持板部の部分は支持円板と重なることにより、強度が向上する。
したがって、支持円板の板厚を薄くしても、従来と同様な強度を確保することができるとともに、ファンロータの重量を軽量化してモータに対する負荷を軽減することができる。
また、連結支持板部および複数の羽根を一枚の金属板にせん断加工および曲げ加工を施すことによって形成し、複数の羽根を連結支持板部に連設させて連結したので、支持円板の中心に重心を一致させて複数の羽根および支持リング板を容易に組み立てることができ、回転時の抵抗を小さくすることができる。
さらに、連結支持板部と複数の羽根とを一体化したので、加工単価を下げることができるとともに、支持円板の中心に重心を一致させて複数の羽根および支持リング板を容易に組み立てることができることにより、製品単価を下げることができる。
さらに、支持円板の外周縁および支持リング板の外周縁にヘミング曲げ加工またはカーリング加工を施したので、板厚が増加することによって強度が増し、また、外周のエッジで手を切ることがなくなる。
According to the present invention, since the plurality of blades are connected to and connected to the connection support plate portion, the strength of the connection support plate portion is improved by overlapping the support disk.
Therefore, even if the thickness of the support disk is reduced, the same strength as the conventional one can be secured, and the load on the motor can be reduced by reducing the weight of the fan rotor.
In addition, the connection support plate portion and the plurality of blades are formed by subjecting a single metal plate to shearing and bending, and the plurality of blades are connected to the connection support plate portion and connected. A plurality of blades and a support ring plate can be easily assembled with the center of gravity coincident with the center, and the resistance during rotation can be reduced.
Furthermore, since the connecting support plate portion and the plurality of blades are integrated, the processing unit price can be reduced, and the center of gravity can be matched to the center of the support disk so that the plurality of blades and the support ring plate can be easily assembled. By doing so, the product unit price can be lowered.
Furthermore, since the outer peripheral edge of the support disc and the outer peripheral edge of the support ring plate are subjected to hemming bending or curling, the strength increases as the plate thickness increases, and the hands are not cut at the outer peripheral edge. .
