摘要

轴孔配合是机械产品基础的装配结构之一，配合间隙对产品的性能优劣和安全、有效运行起着决定性作用。以定位过程中轴孔间隙配合不确定性为研究目标，在分析影响定位过程中轴孔间隙配合不确定性影响因素的基础上，构建了轴孔加工不确定性信息熵模型，用来定量化描述轴孔间隙配合的不确定性；提出用轴孔间隙配合不确定性指标来综合表征轴孔间隙配合精度保持的不确定性；并分析不确定性指标与轴孔间隙配合精度保持可靠性的内在关系；通过实例验证了该方法的有效性和可行性。

Abstract

Shaft-hole fit is one of the most basic assembly structures for mechanical products, and the fit clearance plays a decisive role in the performance, safety, and effective operation of the product. Taking the uncertainty of the shaft-hole clearance fit in the positioning process as the research objective, based on the analysis of the factors affecting the uncertainty of the shaft-hole clearance fit in the positioning process, an information entropy model of the shaft-hole machining uncertainty is constructed to quantitatively describe the uncertainty of the shaft-hole clearance fit. Propose using the shaft-hole clearance fit uncertainty index to comprehensively characterize the uncertainty of the shaft hole clearance fit accuracy retention, and the inherent relationship-between the uncertainty index and the reliability of the accuracy of shaf-hole clearance fit is analyzed; the effectiveness and feasibility of the method are verified through examples.
