Material for Printer Coating Shaft

The material selection of printer glue-coated shaft is mainly determined by the strength, stiffness, wear resistance and manufacturing technology of the shaft, and strives for economy and rationality. There are 35, 45 and 50 high quality carbon steels commonly used for shaft parts, of which 45 steel is the most widely used. Ordinary carbon steels such as Q235 and Q255 can also be used for shafts with less or less important loads.

Alloy steel can be used for large force, limited axial size and weight, or for some special requirements. If 40Cr alloy steel can be used in medium precision and high speed working occasions, the material has better comprehensive mechanical properties after quenching and tempering treatment; if Cr15, 65Mn alloy steel is used in high precision and poor working conditions, the wear resistance and fatigue strength of these materials are better after quenching and tempering; if the axle works under high speed and heavy load conditions, the wear resistance and fatigue strength of these materials are better. Type of parts, such as 20Cr, 20CrMnTi, 20Mn2B low carbon steel or 38CrMoA1A carburized steel, these steels after carburizing, quenching or nitriding treatment, not only have a high surface hardness, but also their core strength is greatly improved, so they have good wear resistance, impact toughness and fatigue resistance. Ductile iron and high strength cast iron are often used in shafts with complex shape and structure because of their good casting performance and vibration reduction performance. Especially the rare earth magnesium nodular cast iron developed in our country has good impact toughness, friction reduction, vibration absorption and low sensitivity to stress concentration. It has been used to manufacture important shaft parts in automobiles, tractors and machine tools.
