根据国家标准GB230-83规定,洛氏硬度值应在平面上进行测量。实际机械零件常具有曲面形状。除了滚动轴承中的钢球具有高硬度外,亦有中、低硬度的球面零件需要检查硬度。由于球面的影响,球面体上所测得的指示硬度值,肯定比材料所具有的真实硬度值低。因此在球面上所测出的硬度值必须进行补偿,才能反映出零件的真实硬度。到目前为止,还没有关于球面体硬度补偿值的标准或公认的计算公式。鉴于生产上 According to the national standard GB230-83, Rockwell hardness values ​​should be measured in the plane. The actual mechanical parts often have a curved surface shape. In addition to the ball bearings in the rolling bearing with high hardness, there are medium and low hardness spherical parts need to check the hardness. Due to the influence of the sphere, the indicated hardness value measured on the sphere body must be lower than the true hardness value of the material. Therefore, the hardness value measured on the sphere must be compensated in order to reflect the true hardness of the part. To date, there are no standard or accepted formulas for spherical body hardness compensation. Given the production
