The following four systems of gear teeth are commonly used in practice: 1.   14 ½O  Composite…

1.  Since the cycloidal teeth have wider flanks, therefore the cycloidal gears are stronger than the…

Involute Profile The following examples are involute spur gears. We use the word involute because the contour…

To obtain the expected velocity ratio of two tooth profiles, the normal line of their profiles must…

For a constant velocity ratio, the position of P should remain unchanged. In this case, the motion…
