針對(duì)結(jié)構(gòu)簡(jiǎn)單的圓柱齒輪減速機(jī)，一個(gè)齒輪對(duì)即構(gòu)成一級(jí)。如果依次切換多個(gè)齒輪對(duì)，則稱之為多級(jí)減速機(jī)。針對(duì)每個(gè)減速機(jī)等級(jí)，逆轉(zhuǎn)輸入軸和輸出軸之間的旋轉(zhuǎn)方向。多級(jí)減速機(jī)的總傳動(dòng)比為各級(jí)傳動(dòng)比相乘所得的值。

根據(jù)傳動(dòng)比因素降低或提高驅(qū)動(dòng)轉(zhuǎn)速，與減速傳動(dòng)比或是增速傳動(dòng)比有關(guān)。大多數(shù)應(yīng)用情況下，需要減速傳動(dòng)比，原因在于驅(qū)動(dòng)扭矩與驅(qū)動(dòng)轉(zhuǎn)速相反，與總傳動(dòng)比因素成正比關(guān)系。

傳動(dòng)比小于大約 10:1 時(shí)，單級(jí)圓柱齒輪減速機(jī)具有相應(yīng)的技術(shù)作用。原因在于齒數(shù)的比例。傳動(dòng)比大于 10:1 時(shí)，驅(qū)動(dòng)齒輪非常小。這會(huì)對(duì)齒輪幾何形狀和可傳遞的扭矩產(chǎn)生負(fù)面影響。

對(duì)于行星減速機(jī)，實(shí)現(xiàn)多級(jí)減速機(jī)的方法異常簡(jiǎn)單。只需延長(zhǎng)內(nèi)齒圈并串行排列多個(gè)單獨(dú)的行星等級(jí)，即可實(shí)現(xiàn)兩級(jí)減速機(jī)或三級(jí)減速機(jī)。例如，行星減速機(jī)的 20:1 傳動(dòng)比是由單一傳動(dòng)比 5:1 和 4:1 相乘所得的值。行星支架中的是太陽(yáng)齒輪，而非驅(qū)動(dòng)軸，這類(lèi)齒輪驅(qū)動(dòng)下列行星等級(jí)。通過(guò)進(jìn)一步延長(zhǎng)內(nèi)齒圈并繼續(xù)提高行星等級(jí)，可實(shí)現(xiàn)三級(jí)減速機(jī)。傳動(dòng)比 100:1 由單一傳動(dòng)比 5:1、5:1 和 4:1 相乘所得。原則上，所有單一傳動(dòng)比均能相互組合，從而實(shí)現(xiàn)多級(jí)行星減速機(jī)。通過(guò)額外的行星齒輪即可增加可傳遞的扭矩。如果內(nèi)齒圈或外殼被固定住，則輸入軸和輸出軸的旋轉(zhuǎn)方向始終相同。
