A gear coupling in which the two halves have curved teeth and tooth patterns which mirror each other. Both the pressure angle and the spiral angle for any contact point on either the concave or convex side of the tooth on the first coupling half, is equal to the corresponding angle for the corresponding point on the convex or concave tooth of the second coupling half. The cross-sectional dimension of the tooth may increase from the inside to the outside of the gear. Axial misalignment of the two shafts which mount the coupling halves can be accommodated by placing the teeth of the two halves on the surfaces of cones having substantially equal apex angles and relieving the surfaces of the teeth in the region adjacent their ends. |
