【蛇形聯軸器】蛇形彈簧聯軸器的結構分析蛇形彈簧的形狀

蛇形聯軸器是一種結構先進的金屬。它依靠蛇形彈簧板來傳遞扭矩。蛇形聯軸器是 機械領域先進的聯軸器傳動元件，也是非常通用的聯軸器傳動元件。蛇形彈簧聯軸器有九種類型
，分別是殼徑
、殼軸、雙法蘭、單法蘭、中間軸、高速、製動輪、製動盤式、安全型等。

蛇形彈簧聯軸器齒是彎曲的：當載荷較小時
，蛇形彈簧的直線部分基本平行於連接軸；當dang載zai荷he變bian大da時shi，蛇she形xing彈dan簧huang的de變bian形xing變bian大da，與yu齒chi的de接jie觸chu弧hu麵mian也ye變bian大da，而er與yu齒chi的de接jie觸chu點dian之zhi間jian的de距ju離li越yue來lai越yue短duan，剛gang度du變bian大da。兩liang半ban聯lian軸zhou器qi的de相xiang對dui轉zhuan角jiao與yu傳chuan遞di的de扭niu矩ju呈cheng非fei線xian性xing關guan係xi，屬shu於yu變bian剛gang度du蛇she形xing彈dan簧huang聯lian軸zhou器qi。直zhi齒chi廓kuo易yi於yu加jia工gong，成cheng本ben低di，但dan隻zhi適shi用yong於yu傳chuan遞di扭niu矩ju變bian化hua不bu大da的de工gong況kuang。曲qu齒chi聯lian軸zhou器qi適shi用yong於yu扭niu矩ju變bian化hua大da
、正反轉的工況
，具有良好的緩衝作用。但曲齒聯軸器工藝性差，製造成本高。
