The history of gears is surprisingly interesting - the process of milling and hobbing gears plus the transmission of torque and movement all find a place here. We will open the "Secret Gear Case" to YT as well through this channel - a personal mission

Hi you got a subs. How i can calculate the backlash in spur gears like the example in the video? More specific the 0.005 value. Thanks
