Asymmetric gear wheel: thermographic analysis

We have studied an experimental system designed to measure the state of stress existing inside asymmetric gear wheels under load. Such experimental system consists of a test bench which constrains the two asymmetric gear wheels at the operating center distance; a load is applied in order to simulate the constraint during operation. For this specific purpose, we have created two gear wheels using a material suitable for experimenting (Delrin). The material's thermoelastic characteristics were identified in advance through the construction and experimentation of stardard test pieces made of Delrin. Such experimental analysis will made it possible to compare in a future article, the stress range of asymmetric gear wheels with that of symmetric wheels.
