Assembling method for second-line rolling bodies of deep groove ball bearing

The invention relates to an assembling method for second-line rolling bodies of a deep groove ball bearing. A worktable with a groove equal to an outer ring in outer diameter is mainly adopted to be matched with a spacer and a positioning shaft for assembling, firstly, an outer ring provided with first-line rolling bodies and a first-line retainer in an assembling mode is placed into the groove, and a second inner ring is placed in the outer ring in a skewing mode; then, the spacer is put into the side, away from the outer ring, of the second inner ring, and the needed second-line rolling bodies are all placed on the spacer; the positioning shaft is inserted into axial holes of the two inner rings, the spacer is taken out, and the second-line rolling bodies are stirred evenly and then inserted into a second-line retainer. The method is easy to operate and easy to start, and the working efficiency can be improved significantly. 本发明涉及种深沟球轴承第二列滚动体的装配方法，主要采用具有与外圈外径相等的凹槽的工作台配合垫片和定位轴进行装配，先将装配好第列滚动体和第列保持架的外圈放入凹槽中，再将
