Abstract: An adjustable camshaft sprocket assembly includes a hub and a sprocket body secured to the hub. A stud-receiving opening is defined in one of the hub flange and the sprocket body, and a tool-receiving opening is defined in the other of the hub flange and the sprocket body. The tool-receiving opening is aligned with the stud-receiving opening is adapted to receive a body portion of an adjustment tool, and the stud-receiving opening is adapted to receive an eccentric stud of the adjustment tool. Either the stud-receiving opening or the tool-receiving opening is elongated. Rotation of the adjustment tool when its body is located in the tool-receiving opening and its eccentric stud is located in the stud-receiving opening causes relative angular movement between the hub and the sprocket body. One or more fasteners are used to immovably secure the sprocket body to the hub after adjustment. A tool includes cylindrical base, a driving head, and an eccentric stud. The stud comprises a spring pin press-fit into a bore.

Abstract translation: 可调节的凸轮轴链轮组件包括固定到轮毂的轮毂和链轮主体。 轮毂法兰和链轮主体中的一个限定了螺柱接收开口，并且在轮毂凸缘和链轮主体中的另一个中限定了工具接收开口。 工具接收开口与柱塞接收开口对齐，适于容纳调节工具的主体部分，并且螺柱接收开口适于容纳调节工具的偏心螺柱。 螺柱接收开口或工具接收开口是细长的。 调节工具在其主体位于工具接收开口及其偏心螺柱中时的旋转位于螺柱接收开口中，引起轮毂和链轮主体之间的相对角运动。 在调节之后，使用一个或多个紧固件将链轮主体固定到轮毂上。 工具包括圆柱形基座，驱动头和偏心螺柱。 螺柱包括压配合到孔中的弹簧销。
