一、5000千瓦单园弧齿轮减速器 鞍钢第一初轧厂是三十年代建立的老厂,初轧机为φ1000毫米,后接24吋连轧机,其主减速器原为渐开线齿轮。随着产量增加进料断面增大,已不能适应生产发展的要求,至61年齿面严重点蚀和磨损并且发生过断齿断轴事故,严重威协生产。为此提出革新方案用园弧齿轮代替渐开线齿轮。在沈阳重型机器厂等单位协助下制造出国内最大的5000千瓦单园弧齿轮
First, 5000 kW single arc gear reducer Anshan Iron and Steel Company first rolling mill is the thirties established the old factory, the first mill φ1000 mm, followed by 24-inch rolling mill, the main reducer was involute gear. With the increase of output, the cross section of feed increases, which is no longer able to meet the requirements of production and development. Severe pitting and abrasion of the tooth surface occurred in 61 years and a broken shaft accident occurred severely, which seriously weakened the production. To this end proposed innovative program with arc gear instead of involute gear. In Shenyang heavy machinery plant and other units to help create the largest 5,000 kilowatts single Park arc gear
