Abstract: One general aspect includes a composite sprocket. The composite sprocket also includes a skeleton having a connection interface and an outer portion having a rough tooth structure. The composite sprocket also includes an overlay formed on and over the outer portion of the skeleton and may include of a precision material and forming a high precision tooth structure over the rough tooth structure.

Abstract: Synchronous belt systems include two or more sprockets, a first endless belt, and a second endless belt. The belts are connected together with belts attachment hardware through belt ports, and a belts gap is defined between the belts. Each of the sprockets includes sprocket teeth and sprocket tooth spaces between adjacent teeth of the sprocket teeth, and each of the sprockets has a sprocket center ridge. The belts each include a plurality of belt teeth which engage sprocket tooth spaces. The belts gap engages the sprocket center ridge of each of the sprockets. Each of the belts attachment hardware includes a connecting bar which renders a parallel and adjacent configuration of the first endless belt and the second endless belt.

Each of the sprockets includes sprocket teeth and sprocket tooth spaces between adjacent teeth of the sprocket teeth, and each of the sprockets has a sprocket center ridge. The belts each include a plurality of belt split teeth, and each split tooth of the plurality of belt split teeth has a first belt ridge, a second belt ridge and a belt split tooth space disposed between the belt ridges. The belts gap engages the sprocket center ridge of each of the sprockets, and each of the belts attachment hardware is disposed within the adjacent belt split tooth spaces of the belts.
