本文就桑塔纳轿车前轮毂轴承一度出现的早期失效现象进行了分析。针对与前轮毂轴承内外套圈配合的轴颈及轴承座孔的配合过盈量进行理论分析 ,经过分级试验 ,由振动及温度监测轴承运转性能 ,合理地确定了圆柱度精度的级别。附图 1幅 ,表 1个 ,参考文献 1 1篇。 This article analyzes the early failures of the front hub bearings of Santana cars. According to the theoretical analysis of the fitting interference between the journal and the bearing seat hole matched with the inner and outer ferrule of the front hub bearing, the grade of the cylindricity accuracy is reasonably determined by monitoring the running performance of the bearing through the classification test and the vibration and temperature.
