A sleeve bearing of the halfshell type wherein an oil film is disposed between the bearing and journaled member during operation and which bearing improves bearing fatigue resistance. The thickness of one of the halfshells is increased to thereby reduce the radius of curvature thereof and the thickness of the other halfshell is reduced by an equal amount to thereby increase the radius of curvature thereof. The halfshells are disposed so as to closely surround a journaled member in a manner such that the higher loads generated during bearing cycling are carried by the halfshell having the greater thickness. This structure acts to reduce destructive oil film pressures developed between the bearing and journaled member during that period of bearing cycling when elevated loads are experienced. In heavy duty sleeve bearing constructions of the trimetal type, the differences in thickness and radius of curvature are achieved through differences in the so called intermediate layers. |
