针对某型车装机枪供弹机内拨弹齿断裂,从对内拨弹齿轴断裂件尺寸检查和金相组织、内拨弹齿轴强度、相关配合零部件部分参数检查和内拨弹齿轴断裂机理等方面逐次展开分析检查,找出初步故障原因后,有针对性地进行故障再现,并采取有效措施,为产品质量持续提高奠定了基础. For a certain type of vehicle mounted machine gun for the bomb machine within the dial teeth break, from the dial dial pinion rupture size inspection and microstructure, within the dial spring strength, with the relevant parts of the parameters check and dial teeth Shaft rupture mechanism and so on one by one to start the analysis and inspection to identify the cause of the initial failure, the fault reappearance targeted and take effective measures for product quality continued to lay the foundation.
