The present invention provides a wear-resistant member for an impeller that is attached to the inlet edge of a blade. A plurality of ceramic wear-resistant pieces having the same thickness as the blade and covering the surface of the holding plate and the protruding edge are fixed to the part protruding further than the blade, in a row adjacent to each other along the protruding edge. This is a wear-resistant member for an impeller, which is characterized by being formed.
本考案を送風機に適用した実施例について図面
を用いて説明する。
An embodiment in which the present invention is applied to a blower will be described with reference to the drawings.

板１９と複数個の耐摩片１８からなる耐摩部材５
７がボルト２０で取り付けられている。 In FIGS. 1 to 4, the impeller 1 has a hub 2,
It consists of a main plate 3, side plates 4, and blades 5. A large number of rectangular ceramic wear-resistant pieces 8 are adhered adjacent to each other with adhesive on the blade surface of the blade 5, that is, the side where the fluid enters. A wear-resistant member 5 consisting of a wear-resistant piece 18 of
7 is attached with bolts 20.
保持板１９は鋼製の平板で、羽根５の羽根裏
面、即ち羽根表面に反対の面に裏打ちする如く取
り付けたときに先端が入口縁７先端より突出する
長さを有する。 The holding plate 19 is a flat plate made of steel, and has a length such that its tip protrudes beyond the tip of the inlet edge 7 when it is attached to line the back side of the blade 5, that is, the surface opposite to the blade surface.
耐摩片１８は羽根の厚さ（この実施例では羽根
表面に耐摩片８が装着されているので羽根５の厚
さと耐摩片８の厚さを足した厚さ）と同じ厚さＴ
を有しかつ保持板１９の突出端縁２１を覆う、例

ましくは0.3mm以下、さらに好ましくは0.1mm以下
と、耐摩片１８の相互を密着させて確実に接着す
ることができる。 The wear-resistant piece 18 has a thickness T that is the same as the thickness of the blade (in this embodiment, the wear-resistant piece 8 is attached to the blade surface, so the thickness is the sum of the thickness of the blade 5 and the thickness of the wear-resistant piece 8).
and covers the protruding edge 21 of the retaining plate 19, for example, the outer surface on the distal end side is a curved surface, that is, the outer shape on the distal end side is circular and L-shaped, and the plurality of retaining plates 19
A protruding edge 21 is provided at a portion that protrudes beyond the inlet edge 7.
are lined up and glued together. In this case, if necessary, the gap between the wear-resistant pieces 18 can be kept at 0.5 mm or less, preferably 0.3 mm, by gluing them in advance in a large, easy-to-work place using a device (a jig, a device that applies pressing force, etc.) as necessary. mm or less, more preferably 0.1 mm or less, the wear-resistant pieces 18 can be brought into close contact with each other and bonded reliably.
