Contact stress between meshing gear tooth flanks is one of the most important factors for the load capacity evaluation of a gear pair. A gear design system was developed using Tooth Flank Film Elements (TFFEs). The TFFEs enable boundary conditions for a contact problem in meshing teeth to be easily dealt with. In order to confirm the reliability of the gear design system, contact stresses between meshing gear flanks of spur gear pair subject to a static load were measured using pressure measurement film, and were compared with calculated ones. In the present paper, contact stresses of a gear pair with some parallel and crossed misalignments were measured, and were com-pared with calculated ones. As a result, even for a gear pair with some parallel misalignments, the Tooth Flank Film Elements can work well, and can yield reasonable contact stresses.
