@den.shp: Animation comparison of gear meshing behavior under different contact conditions. The first case demonstrates improper gear engagement, where only a single contact point exists between the teeth. This leads to unstable load transfer, increased stress concentration, higher vibration levels, and reduced efficiency of the gear system. The second case shows proper gear meshing with at least two simultaneous contact points. This ensures continuous load sharing between teeth, smoother torque transmission, improved stability, and significantly reduced vibration and noise. The difference clearly highlights the importance of sufficient contact ratio in gear design for reliable and efficient mechanical performance. #den_shp #engineering #Science #gear #art
