WebSpur Gear Forces. The first thing we’re going to do is create a quick free body diagram on a gear tooth. We can make our calculations based on the pitch circle diameter. We have the tangential force, F t which is the input force that transmits motion. We can find the tangential force from the torque on the gear. WebHowever, there are joints where the angle from snug to the final torque and a crossed thread overlap using this method. An example of this is certain thread forming screws on soft joints and also non-tension joints like pipe pressure plugs. Solution: The prevailing torque algorithm divides the tightening process into 3 distinct zones.
