来自中国建材数字报网的消息,起重机械是国民经济各行各业生产、运输、吊装、贮备等启动过程所需的重要基础设施,广泛应用于仓库、港口、码头、厂房、贮料场所。长期以来,随着国民经济的蓬勃发展,我国钢铁、冶金、电力、建材、石油、化工、新能源产业、江海隧道及路桥建设等领域对起重机械的需求和带动,使我国起重机行业每年实现了30%以上的高增长。目前,国内起重机械设备年产量达4万台以上,产值愈170亿元,每年消耗中高档钢材超过170万t。在起重机械构件中,减速器是各类部件的核心装备,减速器的性能和结构不但影响和决定起重机械的速度、效率与稳定性,而且与起重
According to the news from China Building Materials Digital Newspaper Network, the crane is an important infrastructure required for the start-up of the production, transportation, lifting and storage of various industries in the national economy. It is widely used in warehouses, ports, terminals, factories and storage facilities. For a long time, with the vigorous development of the national economy, the demand and drive for lifting machinery in the fields of steel, metallurgy, electric power, building materials, petroleum, chemical industry, new energy industry, Jianghai tunnel and road and bridge construction have made the crane industry in our country realize annually More than 30% of the high growth. At present, the annual output of lifting machinery and equipment in China reaches more than 40,000 units, the output value is more than 17 billion yuan and the annual consumption of medium and high grade steel products exceeds 1.7 million tons. In the crane components, reducer is the core equipment of various components, reducer performance and structure not only affect and determine the speed, efficiency and stability of the crane, and lifting
