一、概述圆弧齿轮(即单圆弧齿轮,下同。)在我国已有近二十年的发展历史,并广泛应用于石油、化工、交通运输和发电设备中的鼓风机、压缩机、汽轮机和燃气轮机等许多方面的增(减)速器上。历年来我国制造的高速增(减)速器中约有80%(约1500台)采用了圆弧齿轮,绝大多数工作良好,在国民经济中发挥重要作用,并受到使用部门和工人的欢迎。小汽轮机圆弧齿轮减速器(齿面载荷系数 K=12公斤/厘米~2,圆周速度 V=45米/秒,
I. Overview Arc gear (single arc gear, the same below.) In our country has nearly 20 years of development history, and is widely used in petroleum, chemical, transportation and power generation equipment in the blower, compressor, steam turbine And gas turbines and many other aspects of the increase (minus) speed. In recent years, about 80% (about 1,500 units) of China’s high-speed boosters have adopted circular arc gears, most of which work well and play an important role in the national economy and are welcomed by the departments and workers . Small turbine arc gear reducer (tooth surface load factor K = 12 kg / cm ~ 2, the circumferential velocity V = 45 m / s,
