A gearwheel (20) for a gear step in an electric vehicle transmission (18) includes a gearwheel carrier and a toothed ring (30) having an external toothing (42). The toothed ring is rotationally fixable to the gearwheel carrier. The gearwheel carrier is formed by a first partial carrier (38) and a second partial carrier (40) that are at least partially axially spaced apart and extend from the toothed ring radially inward. An axial spacing of the two partial carriers is greater, at least partially, than an axial length of the toothed ring.

A flexplate for a motor vehicle drivetrain includes a carry plate configured for being connected to an engine crankshaft and a drive plate. The drive plate and the carry plate are separate components attached directly via contact. The drive plate is configured for transferring torque input into the carry plate to a downstream component. A method of constructing a flexplate for a motor vehicle drivetrain includes stamping a carry plate configured for being connected to an engine crankshaft; stamping a drive plate separate from the carry plate; and attaching the drive plate and the carry plate directly together via contact. The drive plate is configured for transferring torque input into the carry plate to a downstream component.

Embodiments of a system, method and apparatus for a gear are disclosed. For example, a metallic gear hub can include an axis of rotation and metallic gear teeth. The metallic gear teeth can be smaller than a final gear teeth size of the gear. The metallic gear teeth can be co-planar with the axis. In addition, the metallic gear teeth can be non-orthogonal to the axis. A polymer layer can be located on the metallic gear teeth to form polymer gear teeth on the metallic gear teeth. The polymer gear teeth can form the final gear teeth size of the gear.

A multi-segment sprocket assembly including a sprocket hub and a multi-segment sprocket. The multi-segment sprocket includes a first partial annular sprocket having a first end that includes a first flange, a second partial annular sprocket having a second end that includes a second flange, and at least a first fastener for releasably securing the first and second partial annular sprockets to the sprocket hub. Also disclosed is a harvester reel including a reel drive mechanism that includes a shaft, and the aforementioned multi-segment sprocket attached to the shaft. Also disclosed is a method for changing speeds of a drive mechanism of for a header of and agricultural harvester. The method includes removing the aforementioned multi-segment sprocket having a first overall diameter from a shaft of the header, and replacing the removed multi-segment sprocket with an aforementioned multi-segment sprocket having a second overall diameter that differs from the first overall diameter.
