《机械制造》1985年第一期上介绍了“一种新颖的三角皮带无级变速器”。它是靠张合两只动轮来实现皮带轮直径的变化,以达到调速的目的。调速时,因定轮不动而是移动两边的动轮,所以两根皮带的间距也相应产生变化。但另一轴上皮带轮的皮带槽是固定的,这就使两根皮带不平行,加快了皮带的磨损。最近,我们设计制造了一种变径皮带轮,克服了上述缺点,现介绍如下: 变径皮带轮结构见附图。调速时,用内六角扳手插入中套1的六角孔内,旋动中套,使两片皮带轮张 The first issue of “Machine Building” in 1985 introduced “a novel V-belt CVT.” It is by Zhang together two moving wheels to achieve the pulley diameter changes in order to achieve the purpose of speed. When the speed is adjusted, the moving wheels on both sides are fixed due to fixed wheels, so the spacing between the two belts also changes correspondingly. However, the belt groove on the other shaft is fixed, which makes the two belts non-parallel and accelerates the wear of the belt. Recently, we designed and manufactured a reduction pulley, to overcome the above shortcomings, are introduced as follows: Reducing pulley structure shown in the drawings.
