An evolution analysis algorithm to predict surface wear of flat gears

The evolution analysis of involute gear teeth profiles and the subsequent prediction of their durability are very important for the operation of autonomous systems (e.g., submarines and spacecrafts). To automatically change failed drive components, a relationship between the gear wear and its life time must be known with high accuracy. In this paper, the evolution of a planar involute gearing subject to an abrasion teeth wearing is analyzed. An algorithm based on the analysis of multiplicative wear criteria is proposed. The results can be used to assess and predict the reliability and durability of gears.
