据国内外学者的研究,发动机缸体等基础零件都有不同程度的变形,变形超限的基础零件,对机械寿命的影响达30%左右。我们对解放CA-10B、CA-10C缸体曲轴轴承座孔不同轴度测量的结果表明,有58.3%的缸体变形超限,出厂一至二年的新缸体不合格率达14%。自一九六五年来,交通科学研究院对解放发动机缸体变形及其整形工艺进行了长期的研究,提出了曲轴轴承座孔的测量方法,并为此
According to the research of scholars at home and abroad, the basic parts such as the engine cylinder block have different degrees of deformation, and the basic parts with deformation overrun can affect the mechanical life by about 30%. The results of different axial measurements on the crankshaft bearing housings of CA-10B and CA-10C found that 58.3% of the cylinders were over-deformed and that the failure rate of the new one to two-year factory was 14%. Since 1965, the Institute of Transportation has conducted a long-term study on the deformation and the shaping process of a liberating engine block. A measuring method for crankshaft bearing holes has been proposed, and to this end
