摘　要:運用“平面二次包絡環面蝸桿傳動”原理，研制一種“軸向可調隙蝸輪蝸桿傳動副”，將它應用到機械力源動力傳動的伺服電機減速機構中，驅動精密滾珠絲杠上的動橫梁來完成對參考力傳感器的粗加載。運用物理學中的“逆壓電效應”原理，采用壓電陶瓷材料和專門的工藝方法制作成的力傳感器微變形補償裝置--壓電陶瓷力發生裝置，并將它應用到機械力源的精加載閉環控制中，實現了大載荷下參考傳感器微小力值變化的精確控制。研制最大負荷為3MN的疊加式力標準機。[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]
