PROBLEM TO BE SOLVED: To provide a gear pump/motor, that is compact, and of a low cost, in which a series of gear pumps/motors can be stably rotated as driving shafts are synchronized. SOLUTION: As supported by a first drive bearing 2a and a second drive bearing 2c provided on a front cover 4a and a body 4b, a drive shaft 3a is rotated by external driving force. A drive gear 1a and a driven gear 1b are engaged, and simultaneously, a drive shaft 3c extended from the drive shaft 3a to be connected by a connection part 5a, and supported by a third drive bearing 2e provided on a rear cover 4c is rotated. A drive gear 1c and a driven gear 1d are engaged, and supported at three points of the first drive bearing 2a, the second drive bearing 2c, and the third drive bearing 2e to be synchronously rotated. Oil is taken from an intake port provided in a side surface, and oil in a tooth groove of the engaged gears is fed from a discharge port. COPYRIGHT: (C)2005,JPO&NCIPI
