新型空穴轴承滚子结构的研究

The Study on Hole Cylinder-Roll Structure in Cylinder-Roll Bearing

经理论计算和生产工艺分析，提出新型轴承滚子结构－空穴滚子来代替修形滚子，可以提高滚子轴承的接触疲劳寿命，降低生产成本．

By theory calculating and technology analysing, raises a new cylinder-roll structure ofbearing-hole roll structure to replace the amending outline roll, which can raise the tired life ofbearing and reduce production cost.
