### Gearboxes Planetary and Spur Designs from Anaheim Automation

For example if one gear has 36 teeth while another gear has 12 teeth the gear ratio would be 3 1. Output Torque Output torque is dependent on the gear ratio used. To obtain a high output torque a large gear ratio would be selected. Using a large gear ratio will lower the output shaft speed of the motor.

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.

Worm gears can thus be used to drastically reduce the speed and increase the torque of a system in only one step in a small amount of space. A worm gear mechanism could create a gear ratio of 40 1 with just a 40 tooth gear and a worm while when using spur gears to do the same you would need a small gear meshing wit another 40 times its size.

The pitch diameter is useful in determining the spacing between gear centers because proper spacing of gears implies tangent pitch circles. The pitch diameters of two gears may be used to calculate the gear ratio in the same way the number of teeth is used. In practice gear design often uses the module system which defines gear ratios by
