1979年日本全国精密机械装配竞赛题,是一种检验偏心的工具(见下图)。应加以说明的是,该图只是为了竞赛之用,不考虑实际生产。图中有些与性能本身无关处仍标上严格的尺寸公差要求。 本题中对主要尺寸一顶尖轴中心高及其中心位置(左右)偏移二项,规定了严格的尺寸要求。如果该项超 1979 Japan National Precision Machinery Assembly Contest, is a tool to test eccentric (see below).

The title of the main dimensions of a top center axis and its center position (left and right) offset two items, provides a strict size requirements. If the item is super
