この発明は、小型バーナ用送風機に用いられる半開放形
遠心羽根車のバランス取り方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for balancing a semi-open centrifugal impeller used in a blower for a small burner.

いる。In order to reduce material and manufacturing costs, this semi-open centrifugal impeller is manufactured by simultaneously punching out and bending the blade part by pressing a single disk, and forming bosses on the pressed disk. An impeller with an attached impeller is used.

本発明は上記の点に鑑み、短時間にして簡単に伝える羽
根車のバランス取り方法を提供することを目的とする。Therefore, the conventional methods have been to use the impeller in a poor quality condition without performing balancing, or to perform balancing by driving rivets into the impeller. However, if you do not balance the impeller, not only will you not be able to improve the efficiency of the blower, but it will also generate noise and vibration, and balancing by riveting will be difficult to balance compared to the material and manufacturing costs of the impeller. It dawned on me that the cost of 100 yen was relatively high. [Purpose of the invention]
In view of the above points, it is an object of the present invention to provide a method for balancing an impeller that can be easily carried out in a short period of time.

A balancing member is formed in the impeller, passed through a hole made in the punched part of the blade 20, and wound around a disc to achieve balance.
〔発明の実施例〕以下、図面にもとづいて説明する。[Embodiments of the Invention] Hereinafter, description will be given based on the drawings.

に形成する。This invention simultaneously punches out and bends the 3 parts of the blade by press-cutting a single disc 1, and forms a donut-shaped shape with a maximum diameter of 35 cm slightly smaller than the diameter of the blade on the pressed disc 1. Attach the backing plate and boss to form the impeller.

することができる羽根車のバランス取り方法である。Next, by attaching the backing plate to the disk, a balancing member of a required weight made of a thin plate or wire is passed through the hole formed in the blade punched portion and wound around the disk to balance the impeller. [Effects of the Invention] As described above, the present invention is a method for balancing an impeller in which the amount of unbalance can be corrected by passing a balancing member of a required weight through a hole and winding it.
