The operational performance of gears regarding smoothness, quietness, wear and life span is largely affected by how gear and pinion teeth make contact. And the geometric characteristic of teeth profile plays a very important role in influencing contact condition during gear transmission. For a nominal involute gear pairs, load concentration on the conjugated teeth would be generated inevitably under...
