Design of New Systems of Controlled Speed Drives


Processes in chemical industries and power plant stations require, to a certain extent, variable speed drives of high power capacity. In contrast to controlled hydrodynamic or friction clutches, a new system of hydrostatic controlled superimposed planetary gears was developed. Design and calculations as well as.American Gear Manufacturers Association Fall Technical Meeting Papers 1990 • 2000 efficiency comparisons to other systems will be described. Practical experiences in the drive of large boiler feed pumps will be explained which prove the reliability of these drives.
