... Abstract The successful design and manufacture of gears are influenced largely by design requirements, material selection, and proper heat treatment. This chapter addresses the cost factors and tradeoffs involved in selecting a material, design features, and a heat treating process to optimize...

... properties of the gears and the subsequent failure modes of the gears. In addition to hardness and acceptable case/core microstructures, a gear design engineer expects gears to maintain pre-heat-treat tooth geometry after heat treatment, if possible. This allows gears to be finished with such minor...

The basic allowable stresses used by gear designers have been conservative in order to acknowledge that design procedures are not precise enough to cater to the very wide range of gear designs, and that material variability and process variability do exist. These basic allowable...
