Zusammenfassung:	A gear-drive pivot system is mainly used for body-building equipment. The gear-drive pivot system replaces a single-axis pivot exiting in most of training equipment by utilizing a sun gear and a planetary gear. By controlling the rotation path and the angle variation of a working arm on the body-building equipment, the sun gear and the planetary gear provide work path relatively reasonable in biomechanics.
