阻尼组件和其相关的制造方法
摘要：
一种组件包括粉末金属外部部分(22)、粉末金属内部部分(20)以及中间构件(26),粉末金属外部部分具有其上形成多个小面的径向朝向外的圆柱形表面(54)，这些小面以交替从粉末金属外部部分的轴向侧沿轴向方向上朝向粉末金属外部部分的相对轴向侧延伸到所述粉末金属外部部分的相对的轴向侧之间的位置；粉末金属内部部分具有其上形成多个小面的径向朝向内的圆柱形表面，小面以交替方式从粉末金属内部部分的轴向侧沿轴向方向上朝向粉末金属内部分的相对轴向侧延伸到粉末金属内部部分的相对的轴向侧之间的位置；中间部件安置于粉末金属外部部分和粉末金属内部部分之间，将粉末金属外部部分与粉末金属内部部分连接在一起。
摘要（英）：

An assembly comprising: a powder metal outer part (22) having a radially inward facing cylindrical surface (54) with a plurality of facets (52) formed thereon that, in an alternating fashion, extend in an axial direction from an axial side of the powder metal outer part toward an opposite axial side of the powder metal outer part to a position between the opposing axial sides of the powder metal outer part; a powder metal inner part (20) having a radially outward facing cylindrical surface with a plurality of facets formed thereon that, in an alternating fashion, extend in an axial direction from an axial side of the powder metal inner part toward an opposite axial side of the powder metal inner part to a position between the opposing axial sides of the powder metal inner part; and an intermediate component (26) disposed between the cylindrical surfaces of the powder metal outer part and the powder metal inner part that connects the powder metal outer part and the powder metal inner part together.
