新聞資訊 >> 共同分享蝸輪蝸桿減速機(jī)的自鎖功能-

蝸輪蝸桿減速機(jī)的傳動(dòng)方式中，蝸輪蝸桿傳動(dòng)具備其他齒輪傳動(dòng)所沒有特性。即蝸桿可以輕易轉(zhuǎn)動(dòng)蝸輪，但蝸輪無(wú)法轉(zhuǎn)動(dòng)蝸桿，這是因?yàn)槲佪單仐U的結(jié)構(gòu)和傳動(dòng)是通過摩擦實(shí)現(xiàn)造成的。蝸輪蝸桿減速機(jī)與齒輪減速機(jī)相比就是具有自鎖功能。蝸輪蝸桿減速機(jī)因具有自鎖止功能而在機(jī)械領(lǐng)域應(yīng)用極為廣泛，比如卷?yè)P(yáng)機(jī)，包裝機(jī)、印刷機(jī)、輸送設(shè)備等等。然而也是因?yàn)槲佪單仐U的摩擦傳動(dòng)方式，也造成了蝸輪蝸桿的傳動(dòng)效率相對(duì)齒輪傳動(dòng)要低很多，這是蝸輪蝸桿減速機(jī)不足的地方。不是所有的蝸輪傳動(dòng)都具有很好的自鎖功能，蝸輪的自鎖功能要達(dá)到一定的速比才能實(shí)現(xiàn)，自鎖效果才會(huì)更佳。這和導(dǎo)程角有關(guān)，即速比小的蝸輪蝸桿減速機(jī)自鎖功能就不是那么理想。
