我国对中、小精密齿轮的制造和测量已有丰富的经验,对于大型精密齿轮的制造和测量则是近年刚刚开始,涉及大型精密齿轮制造的一些设备尚未配套成龙。大连重型机器厂引进西德技术,为马鞍山钢铁公司制造的大型减速机组就是一个典型的例子。按过去的精度,这批机组在东北地区就可协作完成,但机组的寿命不长,按西德技 China has rich experience in the manufacture and measurement of medium and small precision gears. For the manufacture and measurement of large-scale precision gears, it has just started in recent years. Some of the equipment involved in the manufacture of large-scale precision gears are not yet equipped with a complete set of equipment. The introduction of West German technology by Dalian Heavy Machinery Plant is a typical example of a large reduction gear unit manufactured by Maanshan Iron and Steel Company. According to the past accuracy, these units can collaborate in the northeast region, but the crew’s life expectancy is not long, according to West Germany
