The actual value of tooth depth and rootdiameter, after cutting, will be slightly different from the calculation. And we like hearing from our customers that it fits "just right". The overlooked Pitch Plate calculator allows you to fixture any gear of any tooth count for further processing after the teeth are cut - yes the technology is in the numbers and the workholding can be done gracefully. The difference between helical gears and straight-cut gears is largely the fact that torque transfer is less efficient in that there is a third force-component trying to separate the gears laterally as well as radially. From the above, calculated gear ratio we can calculate the speed and torque at output gear. Diametral Pitch Module Pitch Circular Pitch Auto Get Ratios.
