従来より、各種の沈殿池などで使用されるフライト式汚泥掻寄機は図2に示す ように、無端に結合した2条のチェン10に、一定間隔に木製あるいは合成樹脂 製のフライト11を取付け、このフライト11を沈殿池12の底部に敷設したガ イドレール13上を摺動させて、水中軸14,テークアップ軸15,駆動軸16 を介して駆動装置17により駆動し、沈積した汚泥を静かに移動させて、沈殿池 12の一方端に掻き寄せるようになっている。 ここで両側のチェンを同期して回動させる必要があるため、駆動軸16には一 対の駆動スプロケットホイル18を固定して取付け、駆動軸16と駆動スプロケ ットホイル18を同時に回転させる。また水中軸14やテークアップ軸15のス プロケットホイル19,20は同期回転の必要はないから、水中軸14やテーク アップ軸15を固定し、これに各々のスプロケットホイル19,20を回転自在 に装着している。 図3は水中軸14及びテークアップ軸15における、スプロケットホイル19 ,20との組合せ部の断面を示すものである。図3中、19,20はスプロケッ トホイルで、ステンレス鋼あるいはダクタイル鋳鉄で製造する。そのボス部に形 成された孔にCu−Al合金で形成した円筒状のブッシュ21嵌装し、スプロケ ットホイル19,20とブッシユ21とを固定するために、止めネジ22を挿入 する。 スプロケットホイル19,20の、ブッシユ21の外周側には、油溝23を全周 にわたって形成し、その油溝23と連通するように給油口24を設ける。更にブ ッシユ21には前記油溝23と連通するように油孔25を設ける。 14,15は軸で、機械構造用炭素鋼で製造し、スプロケットホイル19,20 が装着される部分に熱処理した機械構造用炭素鋼の円筒状のスリーブ26を嵌着 する。 またブッシュ21の両外側にはオイルシール27を装着する。 28はカラーでスプロケットホイル19,20が軸14,15の軸方向に移動す るのを防止するものである。 2. Description of the Related Art Conventionally, as shown in FIG. 2, a flight-type sludge scraper used in various sedimentation tanks has two chains 10 connected endlessly with wooden or synthetic resin flights 11 mounted at regular intervals. The flight 11 is slid on a guide rail 13 laid at the bottom of the sedimentation tank 12 and driven by a drive unit 17 via an underwater shaft 14, a take-up shaft 15 and a drive shaft 16 to quietly deposit the sludge. It is adapted to be scraped off to one end of the settling basin 12 by moving it to. Here, since it is necessary to rotate the chains on both sides in synchronization, a pair of drive sprocket wheels 18 are fixedly attached to the drive shaft 16, and the drive shaft 16 and the drive sprocket wheel 18 are rotated at the same time. Further, since the sprocket wheels 19 and 20 of the underwater shaft 14 and the take-up shaft 15 do not need to rotate synchronously, the underwater shaft 14 and the take-up shaft 15 are fixed, and the respective sprocket wheels 19 and 20 can be freely rotated. Is attached to. FIG. 3 shows a cross section of a portion of the underwater shaft 14 and the take-up shaft 15 in combination with the sprocket wheels 19 and 20. In FIG. 3, 19 and 20 are sprocket wheels, which are made of stainless steel or ductile cast iron. A cylindrical bush 21 made of Cu-Al alloy is fitted in the hole formed in the boss portion, and a set screw 22 is inserted to fix the sprocket wheels 19 and 20 and the bush 21. An oil groove 23 is formed over the entire circumference of the bush 21 of the sprocket wheels 19 and 20, and an oil supply port 24 is provided so as to communicate with the oil groove 23. Further, the bush 21 is provided with an oil hole 25 so as to communicate with the oil groove 23. Numerals 14 and 15 are shafts, which are manufactured from carbon steel for machine structural use, and are fitted with cylindrical sleeves 26 of carbon steel for mechanical structural use which have been heat-treated on the parts where the sprocket wheels 19 and 20 are mounted. Oil seals 27 are attached to both outsides of the bush 21. 28 is a collar which prevents the sprocket wheels 19 and 20 from moving in the axial direction of the shafts 14 and 15.

【考案が解決しょうとする課題】[Issues to be solved by the device]

しかし、上記したCu−Al合金のブッシュは油による潤滑を必要とし、しか も注入した油(グリース)が流れ出ることを防止するために、ブッシュの両側に オイルシールを装着する必要があって、構造が複雑になる欠点を有していた。 本考案は上記欠点を改善して、給油に要する人手が少なくてすみ、しかも構造 の簡易な汚泥掻寄機を提供することを目的とする。 However, the above-mentioned Cu-Al alloy bush requires lubrication with oil, and in order to prevent the injected oil (grease) from flowing out, it is necessary to install oil seals on both sides of the bush. Had the drawback of being complicated. An object of the present invention is to improve the above-mentioned drawbacks and to provide a sludge scraper having a simple structure and requiring less labor for refueling.

【0004】[0004]

【課題を解決するための手段】[Means for Solving the Problems]

本考案は、汚泥掻寄機において、回転摺動する2つの部材の両方の部材または 片方の部材をセラミックスで形成したことを特徴とするものである。 回転摺動部材をセラミックスで成形したことにより、油による潤滑が不要とな り、給油の人手が省け、又オイルシールが必要なく、構造が簡易化できる。 The present invention is characterized in that, in a sludge scraper, both members or one member of two members that rotate and slide are formed of ceramics. Since the rotary sliding member is made of ceramics, lubrication with oil is not required, labor for refueling is saved, and an oil seal is not required, so that the structure can be simplified.

【実施例】【Example】

本考案の実施例を図面によって説明する。 図1は本考案の実施例の断面図である。図中1はスプロケットホイルで、従来 と同じくステンレス鋼あるいはダクタイル鋳鉄で製造する。そのボス部に形成さ れた孔にサイアロンセラミックス(Si−Al−O−N系セラミックス)で形成 した円筒状のブッシュ2を嵌装し、スプロケットホイル1とブッシュ2とを固定 するために両者間にノックピン3を打ち込む。 4は軸で、従来と同様に機械構造用炭素鋼で製造し、スプロケッホイル1が装 着される部分にサイアロンセラミックスで形成した円筒状のスリーブ5を嵌装し 、軸4とスリーブ5とを固定するために、両者間にノックピン6を打ち込む。 7はカラーで、従来と同じようにスプロケットホイル1が軸4の軸方向に移動す るのを防止するものである。 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of an embodiment of the present invention. Reference numeral 1 in the figure denotes a sprocket wheel, which is made of stainless steel or ductile cast iron as in the conventional case. A cylindrical bush 2 made of sialon ceramics (Si-Al-O-N ceramics) is fitted into the hole formed in the boss portion, and the sprocket wheel 1 and the bush 2 are fixed between the two in order to fix them. Drive knock pin 3 into. 4 is a shaft, which is made of carbon steel for machine structure as in the conventional case, and a cylindrical sleeve 5 made of sialon ceramics is fitted to a portion where the sprocket foil 1 is mounted, and the shaft 4 and the sleeve 5 are fixed. In order to do so, a knock pin 6 is driven between them. 7 is a collar, which prevents the sprocket wheel 1 from moving in the axial direction of the shaft 4 as in the conventional case.

【0006】 上記構成においては、スプロケットホイル1が回転すると、ブッシュ2とスリ ーブ5との間で回転摺動が起こるが、ブッシュ2とスリーブ5とが、いずれもセ イアロンセラミックスであるため、油潤滑を行なう必要がない。サイアロンセラ ミックスはそれ自体が耐摩耗性に優れ、しかもその結晶粒径が2ミクロン程度で あって平滑度が高いため、油潤滑を行なわなくても十分に摩耗に耐えられる。 又、油潤滑を行なわないから、従来のようにオイルシールを必要としない、 又、サイアロンセラミックスは電気抵抗が大きいため、スプロケットホイル1と 軸4との間を電気的に絶縁することになり、電気的腐食を防止することもできる 。 本実施例ではブッシユ2とスリーブ5をいずれもサイアロンセラミックスとし たが、ブッシュ2のみ、あるいはスリーブ5のみをサイアロンセラミックスとす ることもできる。 又、駆動軸の軸受の回転摺動部材も、前記したものと同じ構成にすることがで きることは勿論である。In the above structure, when the sprocket wheel 1 rotates, rotational sliding occurs between the bush 2 and the sleeve 5, but since the bush 2 and the sleeve 5 are both made of sialon ceramics. No need to lubricate with oil. Sialon ceramic mix itself has excellent wear resistance, and its crystal grain size is about 2 microns and its smoothness is high, so it can withstand wear sufficiently without oil lubrication. Further, since oil lubrication is not performed, an oil seal is not required as in the conventional case. Moreover, since sialon ceramics have a large electric resistance, the sprocket wheel 1 and the shaft 4 are electrically insulated from each other. It can also prevent electrical corrosion. In the present embodiment, both bush 2 and sleeve 5 are made of sialon ceramics, but only bush 2 or sleeve 5 may be made of sialon ceramics. Further, it goes without saying that the rotary sliding member of the bearing of the drive shaft can also have the same structure as that described above.
