【考案の詳細な説明】
本考案は片吸込型多翼式送風機に関するもので
ある。[Detailed Description of the Invention] The present invention relates to a single suction type multi-blade blower.
周知の如く、多翼式送風機は同一大きさの他の
送風機に比し、大なる風量と風圧を得られるが、
羽根の取付構造よりして高速回転に耐え難く、従
つて通常は静圧100mmAq程度が限界とされてい
た。 As is well known, multi-blade blowers can obtain greater air volume and pressure than other blowers of the same size.
Due to the mounting structure of the blades, it is difficult to withstand high-speed rotation, and therefore the static pressure is usually limited to about 100 mmAq.
即ち、従来一般の片吸込型多翼送風機は第１、
第２図の如く、デイスクａとリングｂに羽根ｃの
長手方向の両端がリベツトｄで固定され、又リベ

Aq程度が限界とされていたものである。 That is, conventional single-suction type multi-blade blowers have the following characteristics:
As shown in Fig. 2, both ends of the blade c in the longitudinal direction are fixed to the disk a and ring b with rivets d, and in order to correct the distortion of the rotating core caused by riveting, the center e 1 of the ring b and the rotating shaft e is fixed. A plurality of spokes f were stretched between the rivets and spokes, but the strength was poor due to the holding means using rivets and spokes, making it unsuitable for high-speed rotation, and the static pressure was usually 100 mm.
The limit was around Aq.
本考案は叙上の点に着目して成されたもので、
その目的は、羽根を、そのデイスク側リングへの
固着端縁より僅少間隔を存した位置で、回転軸の
ハブに固着したデイスクに取付け、各羽根を極め

来、従つて高速回転に耐え静圧200mmAq以上を得
られる片吸込型多翼式送風機を提供するにある。 This idea was created by focusing on the points mentioned above.
The purpose is to attach the blades to the disk fixed to the hub of the rotating shaft at a position slightly apart from the edge fixed to the disk-side ring, and to attach each blade extremely firmly and without distortion to the rotating core. The object of the present invention is to provide a single suction type multi-blade blower that can withstand high-speed rotation and obtain a static pressure of 200 mmAq or more.
本考案の他の目的は、全リベツト式固着に比
し、製作を容易にし、それだけ低コストに出来る
片吸込型多翼式送風機を提供するにある。 Another object of the present invention is to provide a single-suction type multi-blade blower that is easier to manufacture and can be manufactured at a correspondingly lower cost than an all-riveted type.
次に、上記の目的を達成し得る本考案の一実施
