The chief objective of this paper is to apply an analytical approach for calculating the gearmesh stiffness. In this study, the effect of fillet-foundation deformation is considered for calculating the gearmesh stiffness. Firstly, total gearmesh stiffness is observed. Secondly, the percentage of load shared per teeth is analyzed along the pinion-roll angle variation. The effect of contact ratio is investigated on gearmesh stiffness behavior using two models. Model I is considered for High contact ratio (HCR) spur gear pairs and model II for low contact ratio (LCR). The all the parameters are same for both the models except the addendum coefficient. The addendum coefficient is 1 for LCR gear pairs and 1.5 for the HCR gear pairs. The effect of pressure angle is also shown using three cases. And, the HCR spur gear pair results are compared with LCR gear pairs results. The results show that there is higher mean gearmesh stiffness for HCR gear pairs compared with LCR gear pairs (15.52% for module = 3 mm and pressure angle = 18 deg.). The whole analysis is performed with gear ratio 2. Figures show that the normal load reaches its maximum in the two pairs contact zone for high contact ratio spur gear pairs. In the same way, for the LCR spur gear pairs, the percentage of normal load per tooth is high in the regions of one tooth pair contact while load is low in the regions of two teeth pairs in contact for low contact ratio spur gears.
