More Information
Summary:The utility model belongs to the technical field of gear machining, and particularly relates to a large-modulus gear for finish rolling machining, which comprises a cooling component, a matching fixing component and a pretreatment gear, the matching fixing component is mounted on the lower portion of the cooling component and corresponds to the bottom surface of the gear, and the pretreatment gear guarantees stability of finish rolling machining and keeps blanks not deformed in advance. The pretreated gear comprises a gear blank, a dual-purpose through hole, a connecting boss, a positioning threaded hole and a central shaft hole, and the dual-purpose through hole longitudinally penetrates through the gear blank and is located in an unmachined area. According to the large-modulus gear for finish rolling machining, due to the arrangement of the dual-purpose through holes, when the large-modulus gear is machined, a channel for cooling liquid to flow through can be formed in a whole blank, machining heat is broug
