摘要
对于汽轮发电机护环冷胀强化前的尺寸计算,过去是采用经验式,误差比较大。本文导出的理论解精确地表示了护环强化前后的尺寸关系。工艺实践证明,理论解与实际值相吻合。
The dimensions of turbogenerator retaining ring before strengthening by cold expanding have been calculated by experimental formulae for long years. The error of the dimensions by the calculation from that in practice is somewhat large. The theoretical calculation developed by the author of this article represents the accurate relations of the dimensions of the retaining ring beforr strengthening with that after strengthening and agrees very clcsely with the technical practice.
