Abstract: A wedge loading mechanism (1) for an eccentric planetary traction drive in which a roller having a flexibly mounted shaft (4) is positioned between two raceways (2 & 3) forming a convergent wedge. Rotation of either of the two raceways (2 & 3) wedges the roller within the convergent wedge squeezing the roller between the two raceways (2 & 3) thereby transmitting rotational motion and torque between the two raceways (2 & 3). The flexibly mounted shaft (4) generates differences between an effective supporting stiffness of the roller and an contact effective stiffness at the points where the roller contacts the two raceways (2 & 3). The difference in the effective stiffness allow the roller to operate efficiently at smaller convergent wedge angles.

Abstract translation: 一种用于偏心行星牵引驱动器的楔形装载机构（1），其中具有柔性安装的轴（4）的辊定位在形成会聚楔的两个滚道（2和3）之间。 两个滚道（2和3）中的任一个的旋转楔住了会聚楔块内的辊子，挤压辊子在两个滚道（2和3）之间，从而在两个滚道（2和3）之间传递旋转运动和扭矩。 柔性安装的轴（4）产生辊的有效支撑刚度与辊接触两个滚道（2和3）的点处的接触有效刚度之间的差异。 有效刚度的差异允许辊以较小的收敛楔角有效地运行。
