        摘 要:針對斷路器觸頭聯動的傳統轉軸結構存在的缺陷,設計了一種新的轉軸結構。對現有結構進行了介紹,給出了新轉軸結構的工作原理,并對新轉軸的強度進行了分析,通過對比兩種結構的強度、可靠性、工藝性及機械壽命,證明新結構裝配簡單可靠,解決了傳統轉軸的加工工藝復雜,鉚接變形、松動的缺陷,提高了產品機械壽命,驗證了該轉軸的可靠性。
        關鍵詞:操作機構轉軸;機械壽命;可靠性

        Abstract: Aiming at the defect existing in the traditional circuit breaker contact-linked shaft structure, this paper designed a new kind of shaft structure. This paper introduced the existing structure, gave the working principle of new shaft structure and analyzed the strength of new shaft structure. The comparison of the two structure’s strength, reliability, usability and mechanical life verifies that the new structure is easy to assemble reliably, which overcomes the defects including the complex processing technique, rivetingdeformation and working loose of traditional shaft structure, raises the mechanical life of products and verifies the reliability of this shaft.
        Key words: operating mechanism shaft; mechanical life; reliability
