蝸輪蝸桿自鎖止功能應(yīng)用

朱朱

蝸輪蝸桿

在減速機(jī)的傳動(dòng)方式中,蝸輪蝸桿減速機(jī)有一個(gè)非常獨(dú)特之處，大家注意看；蝸輪傳動(dòng)具備其他齒輪傳動(dòng)所沒(méi)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(guò)摩擦實(shí)現(xiàn)的造成的。

蝸輪蝸桿傳動(dòng)方式具有的自鎖止功能在機(jī)械應(yīng)用很有用處，如，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。

注：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)。這和導(dǎo)程角有關(guān)，即小速比的蝸輪蝸桿自鎖功能就不那么理想。大家發(fā)選根據(jù)自己的需求而定。
