广州轴承厂生产的汽车配件——方向节总成已有30多年历史。万向节总成由十字轴和40个滚针杯组成,杯内的滚针间隙采用3号钙基脂作润滑,杯顶与轴颈处采用丁腈橡胶或水松木作密封圈。但由于3号钙基脂没有防锈性能,并且又能引起密封圈膨胀,因此常常造成产品锈蚀,尤其是密封圈与金属面接触处更为严重,大大降低万向节总成的质量和使用寿命。为解决这一问题,我厂与顺德桂洲华口化工厂联合攻关,进行了大量的调查研究,开展 Guangzhou Bearing Factory production of auto parts - steering knuckle assembly has 30 years of history. The universal joint assembly consists of a cross shaft and 40 needle cups. The needle roller gap in the cup is made of calcium-based grease No. 3 for lubrication. The top of the cup and the journal are sealed with nitrile rubber or cork-pine wood. But because of the calcium-based grease No. 3 no anti-rust properties, and can cause the ring expansion, it often results in product corrosion, especially the contact surface of the seal ring and the metal is more serious, greatly reducing the quality and use of universal joint assembly life. To solve this problem, our factory and Shunde Guihua Hua Kou chemical joint research, conducted a large number of investigations and studies carried out
