我們都知道，蝸輪蝸桿的自鎖性能是很多消費(fèi)者比較看重的，因此，我們只有讓它更好的對(duì)其應(yīng)用才能夠發(fā)揮它的作用，那么在其生產(chǎn)活動(dòng)中該如何準(zhǔn)確的應(yīng)用就成了一個(gè)大問(wèn)題。 </p> <p> 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，比如卷?yè)P(yáng)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。 </p> <p> 在減速機(jī)的傳動(dòng)方式中，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。 </p> <p> 而還有很關(guān)鍵的一點(diǎn)就是：不是所有的蝸輪減速機(jī)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)，這還需要注意下。立式安裝時(shí)，很容易造成潤(rùn)滑油油量不足，當(dāng)減速機(jī)停止運(yùn)轉(zhuǎn)時(shí)，電機(jī)和減速機(jī)間傳動(dòng)齒輪油流失。蘇州汽車蝸輪蝸桿設(shè)計(jì)費(fèi)用</p><p
