外径带凸度的短圆柱滚子是一种新结构的滚子，使用这种滚子的轴承主要有可提高软承的动负荷容量，滚动面的润滑性能好，摩擦系数减少，轴承的使用寿命提高等忧点。文内介绍了带凸度滚子的磨削性能，加工这种滚子时刀板的选择与安装，砂轮与导轮的修整，加工规范的选择以及加工中常出现的主要质量间题。附图7幅，表1个。 Outer diameter convex short cylindrical roller is a new structure of the roller, the use of this roller bearing can improve the dynamic load capacity of the soft bearing, rolling surface lubrication, friction coefficient decreases, the bearing Life expectancy and other concerns. The text introduces the grinding performance of the roller with convexity, the selection and installation of the knife plate when processing the roller, the dressing of the grinding wheel and the guide wheel, the choice of the processing standard and the main quality problems often found in the processing.
