新聞資訊 >> 蝸輪蝸桿減速機(jī)和齒輪減速機(jī)應(yīng)用前景-

蝸輪蝸桿減速機(jī)相對(duì)齒輪減速機(jī)的具體優(yōu)勢(shì)表現(xiàn)在哪里？有人問(wèn)，精度和效率都是齒輪減速機(jī)占優(yōu)，為什么我們還要選擇蝸輪蝸桿減速機(jī)呢？我們先了解下2中類型減速機(jī)的特點(diǎn)就會(huì)明白。高性價(jià)比也是一方面原因。

       齒輪傳動(dòng)效率高優(yōu)點(diǎn)：可傳遞空間任意軸間的運(yùn)動(dòng)和動(dòng)力，即軸可以平行，交叉或交錯(cuò)；轉(zhuǎn)動(dòng)平穩(wěn)，其傳動(dòng)比恒定，大多數(shù)齒輪的傳動(dòng)比是常數(shù)；適應(yīng)范圍廣（傳遞速度、功率范圍都大）；壽命長(zhǎng)；效率高；結(jié)構(gòu)緊湊等優(yōu)點(diǎn)。齒輪傳動(dòng)缺點(diǎn)：制造成本高，剛性傳動(dòng)沒(méi)有過(guò)載保護(hù)作用，振動(dòng)和噪音等。蝸桿傳動(dòng)優(yōu)點(diǎn)：能得到很大的傳動(dòng)比、結(jié)構(gòu)緊湊、傳動(dòng)平穩(wěn)、噪音較小及可以自鎖等。動(dòng)力傳動(dòng)中傳動(dòng)比一般為7.5-100，在分度機(jī)構(gòu)中傳動(dòng)比可達(dá)一千以上.蝸桿傳動(dòng)缺點(diǎn)：傳動(dòng)效率較低，不宜在大功率下長(zhǎng)期連續(xù)工作；為了減磨耐磨，蝸輪齒圈需用貴重的青銅制造，成本較高。
