Abstract: A monolithic rocker arm component includes a first lateral wall defining a first aperture and a first mass reducing feature, an opposing second wall defining a second aperture and a second mass reducing feature, a pushrod receiving member that bridges the first lateral wall and the second lateral wall at a first end of the rocker arm, and a tongue element that bridges the first lateral wall and the second lateral wall at a second end of the rocker arm. The pushrod receiving member routes oil from the first towards the second end. The monolithic rocker arm may have one or more internal regions having lattice structures. Methods for additive manufacturing the monolithic rocker component are also provided.

Abstract: A rotatable assembly, such as a crankshaft or camshaft assembly, includes a first rotatable component and a second rotatable component coupled to the first rotatable component. The first rotatable component includes a first body and defines a plurality of recesses extending into the first body. The second rotatable component includes a second body and defines a plurality of protrusions extending from the second body. The protrusions are disposed inside the respective recesses to allow the second rotatable component to rotate in unison with the first rotatable component.
