5f@Etice, sulfur-nitrided. As shown in FIG. 3, the structure of the sulfur-nitrided link consists of a porous compound layer 30 of sulfide (Fed) and nitride (FesN) from the surface, followed by a compact compound layer 31 of nitride (FesN), Next, a nitrogen diffusion layer 32 and a base metal 33 are formed in this order.

ラスな空孔が油゛だまりの作用をし油膜強度をトげる。The porous compound layer 30 of sulfide (FeS), which is the surface layer, has dynamic properties and solid lubricating properties, so it is effective in galling wear resistance. acts as an oil reservoir and increases the strength of the oil film.
窒化物（ＦｅｓＮ）のコンパクトな化合物層は、非常に

いることも判る。The table below shows a combination of a link fitted with a conventional copper bushing and a bottle coated with hard chrome metal Φ, a combination of the present invention's link treated with sulfur-nitriding treatment and a bottle coated with hard chrome plating, and both the link and the bottle. As shown in the comparison of galling resistance in the case of a combination treated with sulfur-nitriding, it is more than 40 times that of the conventional bearing system. It can also be seen that the combination in which both the link and the bottle were subjected to sulfonitriding treatment had better galling resistance than the combination in which only one (link) was subjected to sulfonitriding treatment.

による電気絶縁性能の低下も防止出来るようになる。According to this example,! Compared to conventional bearing structures that use copper bushings, the pushless bearing structure eliminates the need to fit bushings, and has high galling wear resistance, allowing link and bottle bearings to be made smaller. It is possible to prevent malfunction of the link mechanism due to falling off of the bushings and damage to the electrical insulation performance, and it is also possible to prevent deterioration of the electrical insulation performance due to the generation of abrasion powder of the bushings made of evening silk.
また軸受摩擦部への潤滑油の塗布も不要となる為作業性
の向上とともに、潤滑油の枯渇による焼付が無くなる。Furthermore, since it is not necessary to apply lubricating oil to the frictional parts of the bearing, workability is improved and seizures due to depletion of lubricating oil are eliminated.

い為、軸受を小型化出来る。As described in E, according to the present invention, since the bearing groove structure of the operation link mechanism of gas insulated equipment used in arc-extinguishing gas is subjected to sulfur-nitriding treatment, wear particles such as bronze bushings are removed. Since no generation occurs, there is no deterioration in electrical insulation performance. In addition, there are no malfunctions in the link mechanism or poor electrical insulation performance due to bushings falling off, and the bearing can be made smaller because it has high galling and abrasion resistance.
