摘　要:运用“平面二次包络环面蜗杆传动”原理，研制一种“轴向可调隙蜗轮蜗杆传动副”，将它应用到机械力源动力传动的伺服电机减速机构中，驱动精密滚珠丝杠上的动横梁来完成对参考力传感器的粗加载。运用物理学中的“逆压电效应”原理，采用压电陶瓷材料和专门的工艺方法制作成的力传感器微变形补偿装置--压电陶瓷力发生装置，并将它应用到机械力源的精加载闭环控制中，实现了大载荷下参考传感器微小力值变化的精确控制。研制最大负荷为3MN的叠加式力标准机。[著者文摘]

Preparation of 3 MN build-up force standard machineTANG Chun-qian,GAO Fu-rong,CHEN Ming-hua,CHEN Shi-chao,XU Yin-jie, TAN Hong-hui,YI Wei1.National Institute of Measurement and Testing Technology,Chengdu 610021, China;2.Guangdong Institute of Metrology, Guangzhou 510405, ChinaAbstract:Based on ＂plane double enveloping hourglass worm gearing＂ technology, one kind of ＂axial clearance adjustable warm wheel and worm transmission pair＂ was developed. In the reducing mechanism of servomotor which was the power transmission of mechanical forcing device, the transmission pair could drive the crossbeam on the precise ball screw. This could be used to load the reference force transducer roughly. According to the ＂converse piezoelectric effect＂ principle in physics, piezoelectric ceramic force generator was prepared with piezoelectric ceramic materials and special technological methods, which was a micro-deformation compensator set. In the close-loop control system for precision loading of the forcing device, it could be used to precisely control the tiny force change of the reference force transducer under large load. At present, one build-up force standard machine with the maximum load capacity of 3MN was prepared.[著者文摘]
