  • Noise-reducing machine component
    Patent number: 6616337
    Abstract: A machine component, which may be a race of an antifriction bearing, contains pockets, the borders of which is defined by side-by-side reflecting surfaces which have free boundaries and intersect at alternating peaks and valleys. Vibration or noise to which the machine component is subjected produces mechanical longitudinal and transverse waves which propagate through the machine component, with the longitudinal waves being more intense and less subjected to attenuation. Some of the longitudinal waves encounter the reflecting surfaces which partially convert them into transverse waves, and the transverse waves rapidly attenuate in the machine component itself. Thus, the pockets reduce noise in the machine component.
