Abstract
The current standards and design relationships for the surface durability o f gears are based on contact stress considerations. Thermal effects are con sidered only for scoring failures resulting from the destruction of the lub ricating film owing to temperature rise. This paper investigates the effect of thermal shock and thermal stress cycling on pitting, micropitting and w ear for different gear geometries, materials, operating conditions, machini ng processes and surface treatments. Because of the current interest in app lying surface coating technology to gears, special attention is given to il lustrating the potential benefits of this technology in improving the perfo rmance and extending the life of gears.
