园柱斜齿轮的冷挤压美国福特汽车公司的科学试验室试验成功传动箱中行星园柱斜齿惰轮的冷挤压工艺。其工艺流程为:带中心孔的园柱坯(最经济的方法是反挤成底部穿孔的园筒件)一送入齿轮冷挤模初挤成形——将第二个毛坯放人同一冷挤模、第二个毛坯初挤成形,同时第一个毛坯最后挤成斜齿状。见图一。
Cold extrusion of cylinder helical gear Ford Motor Company in the United States scientific laboratory test Successful planetary gearbox gearbox idler gear in the cold extrusion process. The process is: Central hole with a cylindrical billet (the most economical way is to reverse extrusion into the bottom of the perforated cylindrical pieces) into the gear cold extrusion die extrusion - the second blank put the same cold extrusion Die, the second blank early extrusion, while the first blank finally extruded into a bevel. See figure one.
