7、、變幅機(jī)構(gòu)、索引機(jī)構(gòu)也可用于回轉(zhuǎn)機(jī)構(gòu)。它還用作捆綁物件的司索繩、桅桿起重機(jī)的張緊繩、纜索起重機(jī)和架重空道的承載索等。鋼絲繩要求很高的強(qiáng)度和韌性常采用含碳量0.5%~0.8%的優(yōu)質(zhì)碳素鋼制造。根據(jù)鋼絲韌性(即允許彎折的次數(shù))將鋼絲分為三級(jí):特級(jí)用于載客電梯Ⅰ級(jí)用于一般起重機(jī)Ⅱ級(jí)用作司索繩、張緊繩等次要場合。為了防止腐蝕也將鋼絲表面鍍鋅。鋼絲繩由一定數(shù)量的鋼絲和繩芯經(jīng)過捻制而成。首先將鋼絲捻成股然后將若干股圍繞著繩芯制成繩。鋼絲是鋼絲繩的基

8、本強(qiáng)度單元。起重機(jī)用鋼絲的強(qiáng)度一般為1470~1770MPa之間。繩芯是被繩股所纏繞的撓性芯棒起到支撐和固定繩股的作用并可以儲(chǔ)存潤滑油增加鋼絲繩的撓度。根據(jù)適用的場合不同繩芯分為以下幾種:①金屬芯——用軟鋼絲制成可耐高溫并能承受較大的擠壓應(yīng)力繞性較差適用于高溫或多層纏繞的場合。②有機(jī)芯——通常用浸透潤滑油的麻繩制成亦有采用棉芯的。有機(jī)芯易燃不能用于高溫場合。③石棉芯——用石棉繩制成可耐高溫。二、鋼絲繩的分類二、鋼絲繩的分類1.根據(jù)鋼絲繩
