中小型汽轮机(工业汽轮机、小型汽轮机)广泛采用齿轮减速器来保证动力传动中的转速匹配。1960年以来,元弧齿轮(即单元弧齿轮,下同)在高速齿轮传动中逐渐得到广泛应用,并取得良好的效果。十多年来我厂生产的汽轮机元弧齿轮减速器(或配件)累计在600台(套)以上,在国民经济中发挥着重大作用。元弧齿轮和渐开线(磨齿)齿轮相较,制造工艺简单、生产周期短、成本低、跑合后齿面接触精度较易达到,因而比起过去生产过的渐开线齿轮(软齿面或“淬而不磨”的)运动
Small and medium-sized steam turbines (industrial steam turbines, small steam turbines) widely used gear reducer to ensure that the power transmission speed matching. Since 1960, the arc arc gear (ie unit arc gear, the same below) in the high-speed gear drive has been widely used, and achieved good results. Over the past decade, I plant the production of steam turbine arc gear reducer (or accessories) accumulated in more than 600 (sets), in the national economy plays a significant role. Compared with the involute gear (grinding gear), the arc gear has the advantages of simple manufacturing process, short production cycle and low cost, and the contact accuracy of the tooth surface after the running is relatively easy to achieve. Compared with the involute gear Tooth surface or “quench without grinding”) movement
