在轴承的安装方式、预紧量、预紧载荷、润滑与密封等方面分析计算的基础上, 提出了一种轴承的装配方式。探讨了精密光电转台轴系结构精度, 在样机的装配中运用了这种独特的轴系装配方式, 将装配中难以控制的轴承预紧量转换为调节端盖的厚度, 不但解决了轴系装配中的预紧问题, 而且较好保证了轴系的精度。经多次装调测试证明, 该装配方式能够保证轴承达到最佳的预紧效果, 为转台平稳运行, 实现较高的跟踪精度奠定了基础, 具有较好的实际指导意义。

A bearing assembling method is proposed based on analysis calculation of bearing assembling method, pre-tightening amount, pre-tightening load, lubrication and sealing. The shafting structure precision of the precise opto-electronic turntable is discussed. The unique shafting assembling method is used in prototype assembling, and the bearing pre-tightening amount is converted into the regulation of the end-cover thickness. Not only the pre-tightening problem during shafting assembling is resolved but also the shafting precision is guaranteed. Assembling and debugging experiments show that the assembling method can guarantee the best pre-tightening effect and provides basis for the turntable stable running and high precision tracking, which has better actual guidance.
