摘　　要：杯形薄壁内齿轮的旋压成形技术是近年来发展起来的新技术,采用该技术成形的内齿零件主要包括内花键和内齿轮。为了分析齿轮参数对杯形薄壁内齿旋压成形的影响,本文采用工艺试验的方法,对梯形内花键和渐开线内齿轮旋压成形进行了研究。结果表明:齿数的增加将导致制件内侧出现缩径;齿根处齿厚的增加,有利于材料的径向充填,不利于材料的切向充填;压下量和进给比对两类内齿零件的成形均有显著影响,且前者的影响明显大于后者。Spin-forming is a new manufacturing process for cup-shaped thin-wall inner gear.This technique can be used for forming two types of inner gears.One is internal spline,and the other is inner gear.Analysis of gear parameters on impact of cup-shaped thin-wall inner gear spin-forming,and the spinning process for the two types of inner gears were discussed based on the experimental investigation.It shows that the larger number of gear-tooth would result in reducing the inside diameter of the part;the increase of tooth thickness is favorable for the metal flowing in radial direction and less favorable for the metal flowing in tangential direction;radial reduction and feed ratio have a significant effect both on straight-line inner gear and involute inner gear.
