藉由手把輸入轉速於輸入端，帶動鏈條的移動，鏈條以相同速度傳遞至輸出端轉換成旋轉運動輸出。輸出轉速與輸入端轉速比為輸入半徑比輸出半徑。 Input the rotation upon the handle that drives the chain. The chains transfer the motion into ration onto the output end with the same tangent velocity. The ratio of the input and output velocity is ratio of the input and output radius.
