Power transmitters are highly used in many of our domestic and industrial applications. Due to the rising of the fuel prices and the increase in energy demand, there is a continuous demand for higher efficiency gears. The objective of this work is to present a developed meshing modeling which enables to instantly calculate the power losses due to friction phenomenon between spur gear teeth. The present work gives a better understanding of how to numerically evaluate the friction power losses in spur gears and it is a preliminary study to the future work where the impact of friction and wear phenomena on the material lifetime and energy consumption will be discussed.
