Analysis on retaining ring shrink-fitted on rotor body in 2-pole generator
2극 발전기의 리테이닝 링 열 박음 해석
- Published : 2000.04.20
Abstract
The retaining rings used to restrain the end turns of the rotor winding against centrifugal force require very careful attention during design and manufacture because they have traditionally been the highest-stressed components of the generator. In other words, the rings maintain their shrink fits during their entire service life. In this study, using finite element method, the part of shrink fits in generator was analyzed to obtain residual stresses in retaining ring and contact Pressures between contact surfaces at zero, rated, and 120 rated speeds, respectively.
