摘　　要：在综合国内外水轮机导叶轴套与轴颈公差配合和间隙选择的基础上,推荐聚甲醛钢背复合材料轴套与轴颈配合间隙选择的方法,对我国目前水轮机导叶轴颈尺寸公差的选择提出了意见。On the basis of summarizing tolerance selections on fit and clearance between the guide vane journal and bearing sleeve in China and overseas. A recommendation for the tolerance selection between the journal and the bearing sleeve with polyformaldehyde material was given. Some suggestions to the tolerance selection on the guide vane journaIs currently used in China were made.
