1水泵轴连轴承概述汽车水泵支承系统最早采用的是两套深沟球轮承（见图1）．在纺织机械的促进下，SKF公司在本世纪40年代开发出适用于该支承系统的两列球间距较大的双列深沟球轴承（见图2）。即水泵轴连轴承，它采用有研磨滚道的实心轴代替轴承的内圈，两端密封并填充“终身”
A water pump shaft bearing Overview The first car pump support system is the use of two sets of deep groove ball bearings (see Figure 1). With the help of textile machinery, SKF developed two rows of double-row deep groove ball bearings (see Figure 2) larger in pitch for this bearing system in the 1940s. That is, water pump shaft bearing, which uses a solid shaft with grinding raceway instead of bearing inner ring, both ends sealed and filled with “life”
