在机械工业部重型矿山机械工业局的领导下,自七十年代以来,我所先后主持制订了NGW型行星齿轮减速器系列标准(JB1799—76),及派生系列NGW—z(JB3722—84)、NGW—S(JB3723—84)、NGW—L(JB3724—84)。截至目前已有5000余台产品应用于冶金矿山、起重运输、煤炭、化工等行业,在工业生产中发挥了积极作用。随着“四化”建设的飞速发展,对行星齿轮减速器提出了新的更高的要求——高精度、硬齿
Under the leadership of the Heavy Mining Machinery Industry Bureau of the Ministry of Machinery Industry, since the 1970s, we have presided over and formulated the series of NGW planetary gear reducer standards (JB1799-76) and the derivative series NGW-z (JB3722-84) , NGW-S (JB3723-84), NGW-L (JB3724-84). So far, more than 5,000 products have been used in metallurgical and mining, lifting and transportation, coal, chemical and other industries, and have played an active role in industrial production. With the rapid development of the “four modernizations”, new and higher requirements have been put forward on the planetary gear reducer - high precision, hard gear
