Modeling and Dynamic Force Simulation for Detection of Profile Error in Spur Gear Pair

This paper describes modeling and simulation of spur gear pair in Adams-View. Initially, virtual model of an ideal gear pair is created in Adams and variation of the dynamic force is obtained by considering the tooth mesh stiffness and mesh damping coefficient. The magnitude of force variation thus obtained is confirmed with the design calculations. The dynamic force magnitudes thus obtained and those found in Adams are closely matching. Later on, tooth profile error is introduced in the gear pair by removing part of involute surface from one of the gears making one tooth surface as flat. Dynamic force variation is now obtained for the defective gear pair. After comparing the dynamic forces for defect free and defective gear pairs, it is found that change in dynamic force pattern is a good indicator of tooth profile error in spur gears.
