In mesh of a pair of helical gears, a composite load of distributed load along a contact line moves its operated location from one end of face width to other end in the process of mesh progress. This moving load causes fluctuation of bearing load which excites gear box. So it is important to treat gear mesh excitation as moving load problem. For this purpose two mesh models are proposed. The first model can take moving load into account by discrete multiple springs representing a pair of gear tooth and mesh exciting forces. The second one incorporates exciting moment into the single tooth spring model. Then, response analysis in done for simple gear-shaft model. As the result, moving load causes vibration with non-coupled or independent mode between drive and driven shaft. Thus the effectiveness of the proposed method is established.
