Method for Increasing Surface Durability by Improvement of Surface Roughness Profile Using Processes of Shot Peening and Barreling

摘要

The requirements for a rise in the load bearing capacity of gears to increase torque and to miniaturize automobile transmissions are strict. According to the Kyoto Protocol of 1997 on important problems related to Global Earth warming-up prevention, the target level of reduction of exhaust gases (CO{sub}2, etc.) that exert the greenhouse effect should be reached by 2010 in the countries of the world. Automobiles that are essential for contemporary social life are not the only objects of engine improvement, but problems related to an improvement of the transmission efficiency cannot be neglected in them.
