扩环式单向超越离合器

Expanding Ring Type Overrun Clutch

基于内外圆柱表面之间摩擦力传动的主要思路，在缩环式单向超越离合器[1][2]研究成果的基础上，提出了一种新型的扩环式单向超越离合器；它对超越离合器结构性能的改善和使用性能的提高均将起到积极的作用。

A new type of expanding ring overrun clutch is developed based on the idea that it is driven by the frictional force between the internal and outside cylindrical surfaces. It is developed on the basis of the research results made on contracting type overrun clutch.It plays an important part in improving the structural features and performances of overrun clutch.
