Abstract

PURPOSE: To extend the life of a metal die and thereby reduce production cost by making the whole depth of teeth successively smaller towards both ends of the rack than the rest of teeth with addendum height of the former maintained the same as the latter.
CONSTITUTION: The endmost tooth 14 is located at each axial end of rack 13, and next to this tooth 14, end teeth 15 and then other teeth 16 are successively provided. The addendum height from the pitch line 19 to the tooth crest 17 is the same for all rack teeth 14, 15, and 16. The whole depth of the rack end teeth 15, however, is made smaller than that of the rest of teeth 16. Furthermore, the whole depth of teeth 15 is designed to get smaller in stages towards the both ends of the rack 13. The tooth space 22 at the rack end is provided with an endmost slope 23 which reaches to the outerperiphery of the rack bar.
