The friction coefficient of gear tooth flanks is an important factor in clarifying the mechanism of surface failures such as pitting and scoring and in improving the performance of power transmission gears. This is a basic study to establish a method for evaluating the friction coefficient of a spur gear pair under uniformly distributed load along the tooth trace using the fillet strains measured by strain gauges. Experiments with a rack model were carried out with static loads. The frictional and normal forces acting on the working flank were derived by solving the system of equations concerning the fillet strains on the working and nonworking flank sides. The accuracy of the ratio of the friction force to the normal force was examined. The results demonstrate that in order to obtain a meaningful friction coefficient of spur gears it is very important to consider the independence of the relation between the fillet strain and the forces on the working flank.
