摘要：
为提高橡胶国际硬度测量装置试验力的准确度,提出将空气轴承应用于橡胶硬度测量装置的施力机构。通过分析橡胶国际硬度测量装置对试验力的要求与测量装置的结构,考虑空气静压轴承的刚度、精度与加工特殊性等因素,探讨空气静压轴承应用于橡胶国际硬度测量装置的可行性,并提出完整的空气静压轴承设计加工方案。实验结果表明:该方案试验力偏差是原有橡胶硬度基准的1/10,能有效提高计量准确度,提升我国橡胶硬度计量水平。

Abstract: In order to improve the accuracy of force testing for international rubber hardness degrees (IRHD) measuring device, a solution using aerostatic bearing to improve force mechanism was proposed for the first time in domestic. The paper explores the feasibility of aerostatic bearing used in IRHD measuring device through analyzing the demand of fore mechanism for IRHD measuring device, and the structure, rigidity, accuracy and processing characteristic of the aerostatic bearing. A complete design and machining solution are proposed. Experiment and comparison results indicate that the deviation of testing force is 1/10 of the old one of IRHD measuring device. It can effectively improve the accuracy of IRHD measurement and measure level of rubber hardness in China.
