    • A tensioner for tensioning flexible drives employs an extruded shaft which can provide a relatively complex cross sectional shape to provide anti-rotation features to inhibit rotation of a pivot bushing located on the shaft. The pivot bushing has a frustoconical outer shape, as does the pivot surface of the hub of the tensioner arm which pivots on the pivot bushing. A dampening spring urges the pivot bushing towards the tensioner arm's pivot surface, providing for wear compensation and for dampening. The degree of dampening which is generated between the pivot bushing and the tensioner hub can be selected in a variety of manners: by varying the spring force; by changing the effective contact surface area between the pivot bushing and pivot surface; and/or by changing the coefficient of friction between the pivot bushing and the pivot surface.
    • 用于张紧柔性驱动器的张紧器采用挤出轴,其可以提供相对复杂的横截面形状以提供防旋转特征以阻止位于轴上的枢轴衬套的旋转。 枢轴衬套具有截头圆锥形外形,张紧器臂的轮毂的枢转表面在枢轴衬套上枢转。 润滑弹簧将枢轴衬套推向张紧器臂的枢轴表面,提供磨损补偿和润滑。 在枢轴衬套和张紧轮毂之间产生的阻尼程度可以以各种方式选择:通过改变弹簧力; 通过改变枢轴衬套和枢转表面之间的有效接触表面积; 和/或通过改变枢轴衬套和枢转表面之间的摩擦系数。
