摘要:
产品质量是企业效益的源泉,针对螺旋伞齿轮,首先分析其生产工艺流程;然后,应用统计过程控制(SPC)理论与方法,确定质量改进关键点,并分析其过程能力,制定质量改进措施与方案;最后,对关键工序热处理进行回归分析和全因子试验设计,以寻求影响热处理因素:渗碳温度、渗碳保温时间、淬火温度、回火温度、回火保温时间等的最优组合及其各因素对齿面硬度的影响趋势.通过此项目的成功实施,降低了螺旋伞齿轮的不合格品率,提高了顾客满意度,效果显著.%Product quality is the source of enterprise benefits,for the spiral bevel gear,firstly,the production process of the spiral bevel gear was analyzed;Then,by applying Statistical Process Control (SPC) theory and method,the key points of quality improvement was determined and the process capability of the control points were analyzed and the quality improvement measures and plan were formulated.Finally,the regression analysis and the full factorial experimental design are conducted to find the optimal combination of the key factors and the influence of various factors,such as carburizing temperature,carburizing holding time,quenching temperature,tempering temperature and carburizing holding time.Through the implementation of the success of this project,the failure rate of the spiral bevel gears was reduced,and customer satisfaction was improved,the significant is effect.
