Synchronizer ring producing method, involves forging synchronizer ring in axial extension and cutting shaped ridge by stamping side contour of ratchet tooth and by separating sections unrequired for tooth

摘要

The method involves providing a forge blank. A synchronizer ring is forged in an axial extension by a forging process such that shaped ridges (17, 18) are formed at axial end regions of a forged synchronizer ring raw part (14) in a radial direction. The ridges are formed during the forging process and inwardly or outwardly extended in the radial direction. One of the ridges is cut by stamping a side contour of a ratchet tooth and by separating sections unrequired for the tooth. The raw part is finished by removing shaped ridges, which are formed by the forging process.
