调速型液力偶合器可在运转过程中通过调节充液量来改变其外特性,它起无级变速器的作用,在国外已获得广泛的应用。我国从60年代初开始试验研究,近年来已在造船、冶金、化工等部门得到应用,并取得显著的技术经济效果。我们研制的φ580调速型液力偶合器是 The speed governing fluid coupling can change its external characteristics by adjusting the fluid filling during operation. It functions as a continuously variable transmission and has been widely used abroad. Since the early 1960s, our country began to experiment and research. In recent years, it has been applied in shipbuilding, metallurgy, chemical industry and other departments and achieved significant technical and economic results. We developed φ580 speed hydraulic coupling is
