材とのなじみ性を具備することが要求され。Conventionally, in general, as shown in the perspective view of FIG. 1, the synchronizing ring for a transmission has an inner surface that comes into contact with a rotating tapered cone, and the tapered cone, which is a mating member, is on this contact sliding surface. Surface contact occurs intermittently under high blood pressure, and a key groove 3 into which a key fits is formed on the unilateral peripheral surface, and further,
Since the chamfers 2 provided at predetermined intervals along the outer edge have the function of engaging with the chamfers of the hub sleeve, which is also a mating member, they are required to have strength, wear resistance, and compatibility with the mating member. .

パーコーンと摩擦する1通称ピンタイプのものがある。Therefore, high-strength brass with these characteristics is often used in its manufacture. In addition, there is also a so-called pin type synchronizing ring, which has a thread on the outer circumferential side and rubs against a tapered cone, which is a mating member, on the outer circumferential side.

するようになり、使用寿命短命化の原因となっている。However, with the increase in the output of transmissions in recent years, the above-mentioned conventional high-strength brass synchronizing ring has been particularly susceptible to contact with at least one of the above-mentioned taper cone, key, and chamfer of the hub sleeve. As the sliding surfaces are subjected to high surface pressure, the initial conformability decreases, which leads to frequent abnormal wear due to bright surface wear and adhesive wear, leading to a shortened service life. There is.
