北京齿轮厂担负着供应全国许多汽车厂和机床厂需用的齿轮和高精度蜗轮的任务,但是由于过去对蜗轮的测试方法一直没有确定下来,因此对所生产的蜗轮究竟有多高精度也就不能肯定,成为生产的关键问题。为了使计量测试工作更好地为生产服务,北京市计量管理处于今年三月份派出两名计量测试人员到北京齿轮厂和该厂工人师傅一道组成蜗轮测量小组。经过调查研究、外出取经和查阅资料,用该厂现有的测量设备,进
Beijing gear factory responsible for the supply of many automobile plants and machine tool plants nationwide need gear and high-precision worm gear mission, but because of the past on the worm gear test method has not been identified, so the production of the worm is exactly how high precision Can not be sure, become the key issue of production. In order to make metrological and testing work better for production services, Beijing Metrology Administration sent two metrological testers to the Beijing Gear Factory in March this year to work with the factory workers to form a worm measuring team. After investigation, study and access to information, with the plant’s existing measurement equipment, into
