    Worm gear teeth are in mesh with the thread of the worm. The endwise movement of the thread moves the gear teeth past the floating arrow. If the gear has 60 teeth it takes 60 revolutions of the worm to rotate the gear once around. Speed ratio is 60 1. If the gear has 40 teeth speed ratio is 40 1.

    Worm gears have some special properties which make them differ from other gears. Firstly they can achieve very high gear reductions in a single stage. Because the worm gear has only one tooth the gear ratio is simply the number of teeth on the mating gear. For example a worm gear mated with a 40 tooth spur gear has a ratio of 40 1.

    We ll use three relations we already have. First tan A = sin A / cos A. Second sin A = a/c. Third cos A = b/c. Dividing a/c by b/c and canceling the c s that appear we conclude that tan A = a/b. That means that the tangent is the opposite side divided by the adjacent side . Slopes of lines One reason that tangents are so important is that they give the slopes of straight lines.
