窄V带式无级调速器

Stepless Speeder with Narrow V-Belt

充分利用窄Ｖ 带传动的优点和一种新结构的可变直径双槽带轮，设计出摩擦窄Ｖ带式无级调速器。通过一个手动螺旋装置在机器正常工作状态下，可以很方便地调节输出轴转速。实践表明，其结构简单，工作可靠，寿命长。

Making a good use of the advantages of narrow V-belt and a new structure of double-grooved pulley with variable diameter,a stepless speeder with frictional narrow V-belt has been designed.Under normal working condition,it is very convenient to regulate the rotational speed of the output shaft through a hand -controlled spiral device.The practice has proved that this kind of stepless speeder can be widely used in the machinery transimission because of its simple structure,reliable performance and longer working life.
