Abstract
The disclosed gear system provides distinctive forms of gearing for directly transmitting substantially constant velocity between two shafts, while allowing the angle between the shafts to vary (e.g., by even more than 80.degree.) in any plane during operation. Several forms of gear teeth appropriate for the system are specifically detailed and applied in the design of constant-velocity joints.
