多個帶錐度的摩擦輪外部夾在兩摩擦環(huán)之間，內(nèi)部通過碟簧壓緊夾在壓環(huán)與主動輪之間，由于兩摩擦環(huán)固定不動，當(dāng)電機(jī)帶動主動輪旋轉(zhuǎn)時(shí)，摩擦輪通過主動輪和壓環(huán)的帶動，自轉(zhuǎn)的同時(shí)繞摩擦環(huán)作純滾動公轉(zhuǎn)，從而通過摩擦輪的柄部及滑塊帶動支架旋轉(zhuǎn)。調(diào)速時(shí)，轉(zhuǎn)動調(diào)速手輪（圖中未表示），改變調(diào)速凸輪的角向位置，通過兩凸輪型面使調(diào)速凸輪產(chǎn)生軸向位移，從而改變兩摩擦環(huán)之間的間隙，使所有摩擦輪同時(shí)產(chǎn)生徑向移動，進(jìn)而改變摩擦輪的公轉(zhuǎn)速度，達(dá)到無級調(diào)速的目的。摩擦輪外移，公轉(zhuǎn)速度減慢；摩擦輪內(nèi)移，公轉(zhuǎn)速度加快，最快轉(zhuǎn)速與最慢轉(zhuǎn)速之比為5。只要將調(diào)速手輪調(diào)到一定位置，摩擦輪就相應(yīng)均勻地處于某一位置，支架就能輸出對應(yīng)穩(wěn)定的轉(zhuǎn)速，該轉(zhuǎn)速可直接輸出（190～950r/min），也可通過齒輪、蝸輪蝸桿、擺線針等減速，輸出多種不同的轉(zhuǎn)速和扭矩。
