摘　　要：针对曲轴的普通端面磨削和特殊"凸面"端面磨削,重点介绍了一款压缩机曲轴端面精密数控磨床,其精度高、效率高、自动化水平高、性能稳定等优良性能,满足了大批量生产过程中零件加工Cpk值,打破了进口机床在该领域的一统天下。With the rapid development of modern engineering technology,traditional engineering design jumped onto a new step.For machinery equipment industry,traditional bearing life calcu lation method only related to the load and velocitv can not meet the requirements of current industry design,and the calculation result is a far cry from actual bearing life.Considering kinds of influence factors including forces,lub rication and temperature,bearing life calculation should be corrected.This article comes with tapered roller bearing and focuses on the bearing life influence factors.
