摘要： A steel sheet material is stamped from a coil stock material to form a disc blank member. The disc blank member is pressed to form an ash tray metal member. The ash tray metal member is sized to form a hollow cylindric metal body having a flange portion, a cylindric porion and a bottom portion by a press working. The cylindric metal body is inserted a central porion of a mandrel having a tooth profile part. The cylindric metal body is clamped and held by a drive shaft and a driven shaft which are rotated together with the mandrel. Under this state, the cylindric portion of the cylindric metal body is pressed by a roller. The metal of the cylindric portion of the cylindric metal body is fluidized plastically along the tooth profile part of the mandrel, thereby an internal gear is formed on the cylindric portion. The internal gear is applied to a reduction gear mechanism starter for use in an automobile.

摘要： A wear-resistant metal member comprises a surface that has a sprayed layer consisting essentially of, by weight, 2 to 10% C, 18 to 60% Cr, 0.3 to 20% V, 25% or less Mo, 25% or less W, 10% or less Nb, 10% or less Ti, 10% or less Zr, 10% or less Hf and the balance being Fe in a proportion of 20% or greater. The sprayed layer has a martensite-phase matrix containing carbide particles, nitride particles or carbonitride particles. In addition, the member of the present invention is produced by the steps of: plasma-spraying the above-described metal in a reduced pressure atmosphere; and quenching the thus-sprayed metal layer from a predetermined temperature to form a materisite phase in that layer. In addition, the sprayed metal layer may be subjected to carburizing, nitriding or carbonitriding to form a carburized, nitrided or carbonitrided layer in the sprayed metal layer. The member of the present invention has a high wear resistance and is used as a sliding portion of a valve gear in an internal combustion engine.

A driven shaft is disposed in the casing at an inclination angle of 20.degree. against the driving shaft, supported by a bearing provided on an end of the driving shaft, and driven by the driving shaft. A cylinder block is fixed to the driven shaft and has a cylinder bores receiving pistons coupled with the rotary plate so that the pistons reciprocate in the cylinder bores upon rotation of the driving shaft. A side plate is secured to an open end of said casing and has a bore receiving a bearing for supporting one end of the driven shaft. The bore is formed in the inside the side plate which projects outside, so that a distance between the bearing of the driving shaft and the bearing in the bore is extended and stable.

摘要： A method of mechanically processing the cylindrical surface of a part having a cylindrical portion. The cylindrical portion is beforehand provided with a supporting portion at its one end, for producing and imparting a tension to the surface to be processed. An axial relative movement is caused between a punch fitted in the cylindrical portion and a die fitted around the same, so that a plastic deformation is caused on the cylindrical surface to form grooves or teeth in the cylindrical surface, while applying a tension to the material of the cylindrical portion presenting the cylindrical surface.
