METHOD OF MANUFACTURING UNIVERSAL JOINT HOUSING

摘要

D-4,645 C-3296 METHOD OF MANUFACTURING UNIVERSAL JOINT HOUSING A housing for a tri-pot universal joint is manufactured from a tube blank which is cold formed in a two-step indenting process. The indenting process forms the middle of the tube into a tri-lobal section for broaching internal drive tracks while leaving the end portions sufficiently intact to provide circular bands at each end by subsequent machining operations. A closure is attached to the band at one end and the band at the other end is used to mount a conventional boot. A machine having a cam die arrangement suitable for indenting the tube blank is also disclosed.
