Latest Patents

Takahito Shimada holds 1 patent related to an indentation resistance measurement method. His patent encompasses several key methodologies, including an indentation resistance prediction method for rolling bearings, machining condition selection method, bearing material quality selection method, burnishing condition selection method, and a comprehensive bearing manufacturing method. The method for measuring indentation resistance involves obtaining a first curve that indicates yield shear stress in the depth direction of a raceway surface of a material forming a rolling bearing before machining. It also includes a second curve indicating static shear stress after machining and a third curve showing static shear stress when rolling elements are in contact with the raceway surface under static load. The correlation between area and indentation depth of the raceway ring is defined by the region surrounded by the first and second curves and falling below the third curve.
