It is the use of the main, driven belt wheel diameter change to cooperate with each other and transform the work of the belt on the pulley diameter, to implement the work than continuous change, the continuous variable speed engine through the transmission system is obtained. Even if the infinitely variable speed technology in the automotive industry development and the application of time is not long, but pared with other traditional manual or automatic transmission. Mechanical friction stepless transmission is monly used in machinery industry, are generally through the application of belt transmission to realize the stepless speed change, also is what we call belt type stepless.Key words: Belt drive。 Stepless transmissiIV金陵科技學(xué)院學(xué)士學(xué)位論文 第1章 緒論1緒 論源于無級(jí)變速器(Continuously Variable Transmission)可以滿足機(jī)器在運(yùn)轉(zhuǎn)過程中即工作情況經(jīng)常改變或運(yùn)轉(zhuǎn)速度連續(xù)變化的要求,所以它可以廣泛的應(yīng)用于各類行業(yè)當(dāng)中,例如服裝、食品、造紙、橡膠等輕工行業(yè),而且還應(yīng)用于工作機(jī)床、
