Abstract:
Shot peening is a process which might well be considered in the design of any machine part which is required to carry high loads with a minimum size or weight of the overall
unit.
T
his paper represents an attempt to show that shot peening can be used effectively not only to eliminate fatigue failures, but also in design, to increase load carrying
capacity per pound of gears as well as other machine parts.
N
aturally, any pair of gears designed for high load carrying capacity involves good manufacturing practice with respect to the geometry of the gears, material, manufacture
and metallurgy. As in any other machine part, the improvement by virtue of shot peening will start from the level of quality of the gears without the benefit of shot
peening.
A
few years ago, shot peening of a particular machine part may have been looked upon as evidence that the part in question had at some time given trouble in service by reason
of fatigue failures. Today shot peening is being considered more and more as a means of increasing the allowable fatigue strength in the design of machine parts. The fact
that a part is being peened in production does not necessarily imply that fatigue failures have been experienced on that part in the field.
