在渐开线齿轮的制造工艺中,通常是在齿形加工完毕后热处理,然后再进行磨削内孔和珩齿,以提高齿轮的制造精度。其内孔的精加工一般是利用爪形弹性卡盘或三圆弧自定心夹具定位夹紧齿轮,然后在磨床上磨削内孔,其夹具制造费用高,且专用性强,不适合我们厂摩托车齿轮中等批量,多品种的生产要求。因此,我们设计了一种简单的弹性夹具,用齿轮的齿形定位,通过滚柱,利用普通三爪自定心卡盘夹住夹具和齿轮,在普通磨床上磨内 In the involute gear manufacturing process, usually after the tooth profile processing heat treatment, and then grinding hole and honing, in order to improve the gear manufacturing precision. The inner hole of the finishing is generally the use of claw-shaped elastic chuck or three arc self-centering fixture positioning clamping gear, and then grind the hole in the grinder, the fixture of high manufacturing costs, and strong specificity, not for us Factory motorcycle gear medium batch, multi-species production requirements. Therefore, we designed a simple elastic fixture, with the gear tooth-shaped positioning, through the roller, the use of ordinary three-jaw self-centering chuck chuck and gear, grinding in the ordinary grinding machine
