| Abstract: | Self-aligning ball bearing is widely adopted by large precision instruments due to its distinctive performance. For carrying out detailed investigation of a full instrument system, practical stiffness formulae of such a bearing are introduced with elastic contact mechanics, which are successfully applied to calculating the radial and axial stiffnesses of the bearing used by the large astronomical telescope, LAMOST. Appropriate treatment of the stiffnesses of such bearing in finite element analysis is discussed and illustrated at the end. |
