Abstract

PURPOSE: To reduce the weight of rocker arm and to improve its bouncing effect, by making the main body of rocker arm with aluminum alloy and forming its pad portion with sintered alloy of a specific composition integrally by way of internal chilling.
CONSTITUTION: Main body 1 of rocker arm is made of aluminum alloy, whereas pad portion 2 is formed integrally with the main body 1 by fixing a chip of sintered alloy to the pad portion by way of insertion. Sintered alloy forming the pad portion 2 is manufactured by shaping, by way of compacting, powder of alloy having a chemical composition of 0.5W2.0% of C, 1.5W4.0% of Co, 0.5W6.0% of Mo, 4.0% of at least one of Cr and W, 0W2.0% of P and remaining part of Fe, and sintering the same in a non-oxidizing atmosphere at a temperature of about 1000W1200°C for about 10W60min by way of partial liquid-phase sintering method. By manufacturing the rocker arm in the manner described above, weight of rocker arm can be reduced and its bouncing limit can be extended.
