钢琴弦轴的扭矩,是关系到钢琴质量,特别是音准稳定性的重要技术指标。钢琴弦轴的扭矩,需用扭矩扳子测量。据了解,国内尚没有生产这种专用检具的部门。为了完善我国钢琴生产的质量保证措施,推动我国钢琴工业的发展,北京乐器研究所于1991年立项并研制成功钢琴弦轴扭矩扳子。北京乐器研究所研制的钢琴弦轴扭矩扳子综合了日本及德国同类产品的优点,为卧 The torque of the piano string shaft is an important technical index that relates to the piano quality, especially the pitch stability. Piano string shaft torque, the torque wrench to be measured. It is understood that there is no domestic production of such special gage department. In order to improve the quality assurance measures of piano production in our country and promote the development of piano industry in our country, Beijing Instrument Research Institute set up and developed a successful piano string torque wrench in 1991. The piano string shaft torque wrench developed by Beijing Musical Instrument Institute combines the advantages of similar products in Japan and Germany for lying
