Abstract
PURPOSE: To improve wear resistance of a bearing alloy independently of the material of a shaft, especially by addn. of Cr to a bearing alloy of Al-Sn type.
CONSTITUTION: As an alloy for bearing of an internal combusion engine is used an alloy comprising 3.5W35 % Sn, 1W7 % Cr, or further comprising ≤3 % Cu, or Mg, still comprising ≤9 % at least one member selected from the group consisting of Pb, Bi, In, the balance being Al. This bearing alloy is pressed to a backing steel plate to manufacture a bearing. Increase in Cr content increases hardness of the bearing alloy so as to prevent softening at high temp., causes no increase in size of Sn particles, and improves wear resistance independently of the material of the partner. Addn. of Cu, Mg simultaneously with Cr never decreases hardness, which is increased due to rolling, during annealing. Addn. of Cr, Pb, Bi, In refines Sn, improving adaptability and hardness. The alloy shows excellent performance when used for a shaft made of spheroidal graphite cast iron, the shaft which is used under particularly severe conditions.
