heal.abstract	A new model of improved accuracy is proposed for the simulation of the dynamic behavior of a pair of spur gears that are free from manufacturing and mounting errors. The load-induced expansion of the actual path of contact with the occurrence of tooth edge contact is taken into account in order to better explain the tooth load sharing process near the lowest and highest point of single tooth contact (LPSTC, HPSTC). In addition, an accurate friction model is utilised and the effect of elastohydrodynamic lubricant film formation on gear vibration is taken into account. Simulation results are extracted for various operating speeds and an evaluation of the proposed model is conducted. The model is constructed in a modular fashion and can consequently be used as a building block for larger mechanisms, such as gear trains and multi-stage gearboxes.	en
