MANUFACTURING METHOD FOR A DRIVE BELT RING COMPONENT.

摘要

The invention concerns a method for manufacturing an endless metal ring (32) for a drive belt suitable for power transmission in a continuously variable transmission including at least a process step (IX) of nitriding or case hardening the ring (32) in an oven chamber (50) containing a process atmosphere that is supplied with both ammonia gas and with hydrogen gas. Preferably, at least the relative volume content of the hydrogen gas present in the oven chamber (50) is actively controlled to a desired value.
