常用的起动机超越离合器的盖板是平扳形的,这种盖板不能用润滑油密封方式来密封空间,故其使用寿命实际上很短。西德波许公司发明了一种更为有用的滚柱型超越离合器,该离合器适用于内燃机用起动机。它有一个内滚道和一个外滚道。内滚道与起动机小齿轮连成一体,外滚道通过凸缘和驱动套筒形成整体结构。外滚道内表面为角偏移的楔形面,该面与离合器轴线呈偏心式延伸。滚柱和螺旋弹簧安放在小室中,小室中有
Common starter over the clutch cover is a flat-shaped, this cover can not be sealed with a lubricating oil space, so its service life is actually very short. West Germany Bo Xun invented a more useful roller overrunning clutch, the clutch is suitable for internal combustion engine starter. It has an inner raceway and an outer raceway. The inner raceway and the starter pinion are connected together, and the outer raceway forms a whole structure through the flange and the driving sleeve. The inner raceway of the outer raceway is an angularly offset wedge face that extends eccentrically with respect to the clutch axis. Rollers and coil springs are housed in a small chamber
