  • Method of making star gear for constant-velocity joint
    Publication number: 20060236542
    Abstract: A star gear for a constant-velocity joint is made by first forming in a steel blank without material removal a center hole of noncylindrical shape and defining an axis. Then a complementary mandrel is fitted in the formed center hole. Finally a plurality of outwardly open grooves are cut into an outer surface of the blank in a chip-removing process while the blank is on the mandrel.
