Abstract

It is shown that deformed steel has an advantage over cast steel in terms of mechanical properties. It was revealed that the decrease in the durability of gear parts is associated with the presence of metallurgical defects in the steel. The square segregation is always inherited by the finished part and its appearance on the surface leads to the destruction of the product. The dendritic structure of steel is the reason for the low endurance strength of the tooth of the part. For heavily loaded gear parts of the «shaft-gear» type, it is recommended to use rolled products with a high degree of crimping (extension). To eliminate the dendritic structure in steel, hot deformation of the metal can be carried out at the stage of forging production.
