Slow Motion - How an Impact Wrench Works
Look at impact guns an impact gun works by storing energy in a heavy rotating mass and then releasing it all at once in small impacts against the output shaft this puts a lot more force on the bolt or nut that you're trying to tighten or loosen and it takes a lot of the string off your wrist.
This is my personal impact gun so I won't be taking apart but I have one of these they went on sale for two dollars at Canadian Tire and they're supposed to be able to let you turn a standard drill into an impact gun just by putting it in the Chuck.
So,let's take a look at these two how they work in normal operation and then we'll take this one apart and look at it in slow motion filmed at frames per second you can see the hammering action in both tools for the most part the bits sit still except when it is periodically hit by the hammer internally as it engages with the output shaft taking the impact.
Wrench adapter apart was surprisingly easy he was only held together with three small hook screws that weren't hidden or covered and they weren't the safety torques that have the little dot in the middle here you can see the hammer and out foot shaft as they fit together and the spring that pushes the hammer into the output shaft to give it that periodic hammering action..
