由我院冶金机械教研室承担的、国家七·五重点科技攻关项目的四级子课题“热轧机轴承的载荷谱分析”,于1990年5月5日～7日在三级子课题的负责单位洛阳轴承厂的主持下通过鉴定。该项研究揭示了轧机轴承载荷谱的特征,找出了四辊轧机工作辊四列圆锥滚柱轴承失效的主要原因,提出了改进该类轴承设计的具体建议,并对所采集的轧机轴承载荷谱和轴承座振动信号进行了时域、频域、幅域等各域信息分析,为乳机轴承的计算机设计与试验研究提
Metallurgical Machinery Teaching and Research Office of our hospital commitment, the national five-point key scientific and technological project four sub-topics “hot-rolled bearing load spectrum analysis”, in May 5, 1990 to 7 in the three sub-topics responsible Unit under the auspices of Luoyang Bearing Factory passed the appraisal. The study revealed the characteristics of rolling mill bearing load spectrum and found out the main reasons for the failure of the four-row tapered roller bearing of the work roll of the four-high rolling mill. The concrete suggestions for improving the design of the bearing were put forward. The mill bearing loads Spectrum and bearing vibration signals were carried out in the time domain, frequency domain, domain and other information analysis of the domain, the design and test of the milk machine bearing computer research
