Patent number: 8282322Abstract: Race grooves and lobe outer surfaces of a constant-velocity race gear centered on a gear axis are finished by engaging a first groove of the race gear with a rotating groove-machining tool and relatively moving the race gear and rotating groove-machining tool arcuately to finish the first groove while holding the race gear against rotation about its gear axis. Then the first groove of the race gear is disengaged from the rotating groove-machining tool while holding the race gear against rotation about its gear axis. Then the race gear is rotated about its gear axis to align a second groove with the rotating groove-machining tool while engaging a first lobe outer surface with a rotating surface-machining tool to finish same. These steps are repeated in the same order to finish the second groove and a second lobe outer surface and so on until all the grooves and lobe outer surfaces of the race gear are finished.Type: GrantFiled: July 31, 2008Date of Patent: October 9, 2012Assignee: Emag Holding GmbHInventor: Norbert Hessbrüggen
