摘要
对于底部有支撑轴承结构的大型反应釜,底部凸缘与顶部法兰的同轴度要求至关重要,直接影响着轴系的运转稳定性及使用寿命,整体机加工能保证精度要求,但成本较大、经济性差,对于机加工能力一般的中小型企业,是一个瓶颈。通过实验,我们找出一种经济合理的制造工艺来达到目的。
A large reactor support bearing structure for bottom, The coaxial degree of the bottom flange and the top flange is crucial, it is directly affects the running stability and service life of shafting, The whole machining can ensure accuracy requirements, But the larger cost ,bad economy, For the machining ability of small and medium enterprises, it is a bottleneck. Through the experiment, We find a manufacturing process to achieve the purpose of economic reasonable.
