Abstract
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.
Claims19
A gear, comprising:
- a metallic gear hub consisting of a monolithic gear core having an axis of rotation and metallic gear teeth that have roll, pitch and yaw axes and are smaller than a final gear teeth size of the gear;
- wherein the metallic gear teeth are not co-planar with each other such that at least some of the metallic gear teeth are offset from each other, and the metallic gear teeth are oriented at a roll angle relative to the axis, and the roll angle is in a range of about 30 degrees to about 60 degrees relative to neutral;
- and
- a polymer layer on the metallic gear teeth to form polymer gear teeth on the metallic gear teeth, wherein the polymer gear teeth comprise the final gear teeth size of the gear, such that the metallic gear hub is configured to fully support a contact line of a mating gear.
A gear, comprising:
- a metallic gear hub consisting of a monolithic gear core having an axis of rotation and metallic gear teeth that have roll, pitch and yaw axes and are smaller than a final gear teeth size of the gear;
- wherein
- the metallic gear teeth are oriented at a roll angle relative to the axis, and the roll angle is in a range of about 30 degrees to about 60 degrees relative to neutral;
- the metallic gear teeth are not co-planar with each other such that at least some of the metallic gear teeth are offset from each other;
- and
- a polymer layer on the metallic gear teeth to form polymer gear teeth on the metallic gear teeth, wherein the polymer gear teeth comprise the final gear teeth size of the gear.
A gear, comprising:
- a metallic gear hub consisting of a monolithic gear core having an axis of rotation and metallic gear teeth that have roll, pitch and yaw axes and are smaller than a final gear teeth size of the gear;
- wherein
- the metallic gear teeth are not co-planar with each other such that at least some of the metallic gear teeth are offset from each other;
- the metallic gear teeth comprise overhangs that extend in opposite axial directions, wherein an overhang outer axial dimension between opposite ones of the overhangs exceed a hub outer axial dimension of the metallic gear hub;
- and
- a polymer layer on the metallic gear teeth to form polymer gear teeth on the metallic gear teeth, wherein the polymer gear teeth comprise the final gear teeth size of the gear.
