遵照毛主席关于“人类总得不断地总结经验,有所发现,有所发明,有所创造,有所前进”的教导,我们对轴承钢钢球压碎负荷的计算及诸种因素对其压碎负荷值的影响,作了一些试验研究,现综合介绍如下. Following Chairman Mao’s teaching on “human beings always summarize experiences, find out, find inventions, create and advance”, we calculate the crushing load of bearing steel balls and crush them with various factors The impact of load value, made some experimental study, are summarized below.
