《机械制造》1985年第1期和1986年第7期上曾分别刊登了“一种新颖的三角皮带无级变速器”和“介绍一种可调速的三角皮带轮”。这两种结构型式不完全相同的变径皮带轮,其变速原理是相同的,都是利用连续改变皮带和皮带轮的接触半径达到变速的目的。但在具体结构方面,还可进一步完善,才能更好地发挥其长处。 “Machinery Manufacturing” 1985 the first period and the 1986 issue of 7 were published in “a novel V-belt CVT” and “introduction of a variable speed V-belt pulley.” The two structural types are not the same variable pulley, the transmission principle is the same, are the use of continuous changes in the contact radius of the belt and pulley to achieve the purpose of speed. However, in terms of specific structure, it can be further improved in order to better play its strengths.
