圆锥滚子轴承外凸曲线型大挡边的加工研究与实践

A Research into and Practice of Tapper Roller Bearing's Convex Forced Cone Rib Processing

针对国产轻型轿车对中小型圆锥滚子轴承外凸曲线型大挡边的设计要求,介绍该类轴承大挡边中外凸曲线的加工方法.通过对30310圆锥滚子轴承进行试验加工后的检测对比发现,具有大挡边带外凸量的该类轴承较之前的直挡边轴承的振动指标合格率有明显提升.

Aimed at the design requirement of convex forced cone rib in small and medium-sized tapper roller bearings, which are used in domestic light vehicles, this paper introduced the processing method of convex forced cone rib in these bearings. Through detection and comparison of processed and unprocessed bearings of type 30310, the vibration qualified rate of the bearings with convex forced cone rib improved more significantly than that of those with straight forced cone rib.
