发明名称 Production method for a toothed wheel
摘要 The method involves cutting a washer to obtain a plate having a hub (10) pierced with a central hole (12), an arm (14) and a felloe (16) connected to the hub by the arm. An outer part of the felloe is pressed to have a peripheral ring whose thickness is lower than that of an inner part of the felloe. Teeth (24) are machined in the ring by rough milling and then by fine milling of the teeth.
