摘要
同步器齿毂是汽车变速箱内的重要零件,如何生产出高精度、高质量的粉末冶金同步器齿毂是一个非常重要的课题。本文通过对异形键槽的粉末冶金齿毂生产工艺过程的分析,从模具的选材、模具结构、模具间隙、模具尺寸等方面,对同步器齿毂压制模具进行优化设计,使模具具有高使用寿命;同时,生产出来的同步器齿毂具有高精度、高质量。
Synchronizer gear hub is the most important parts of transmission, how to produce high precision, high quality of the powder metallurgy synchronizer gear hub is a very important topic.This article through to the abnormity of the keyway powder metallurgy, gear hub production process analysis, from the die material selection, die structure, die clearance, die size, etc., optimize the synchronizer gear hub pressing die design, die with high service life; at the same time, to produce synchronizer gear hub with high precision, high quality.
