1958年我们开始学习圆弧齿轮,试制了几台小型圆弧齿轮减速箱,以后逐渐推广使用于轧钢机及其它冶金设备,改造设备齿轮传动装置的薄弱环节,收到了较好的效果。一、试用圆弧齿轮,改造小型轧机我们在1962年设计和制造了一台中心距为1100毫米的圆弧齿轮减速箱,用于400毫米粗轧机的传动装置。使用半年即发现齿面点蚀和剥落。我们分析齿轮损坏原因:一是齿轮理论中心距与箱体镗孔中心距配合不适当;二是齿面火焰表淬造成的恶果。随即按箱体实测中心距(未查到数据)调整齿轮螺旋角,制作第二
In 1958, we began to study the arc gear, trial production of several small circular gear reducer, after the gradual promotion of the use of rolling mills and other metallurgical equipment, transformation of equipment, gear transmission weaknesses, received good results. First, the trial arc gear, the transformation of small rolling mill We in 1962 designed and manufactured a center distance of 1100 mm arc gear reducer for the mill 400 mm roughing gear. Use six months that tooth surface pitting and peeling. We analyze the causes of gear damage: First, the center distance between the gear theory and the center of the bore of the box with improper coordination; the second is the flaw caused by the flames table tooth quenching results. Then measured by the actual center of the box (did not find the data) to adjust the gear helix angle, making the second
