<p>PURPOSE: To remarkably reduce the axial force component caused by the structure of a device and to use a small bearing by applying the reaction force to a counterpart fixed both in the rotating direction of a rotor and the axial direction, CONSTITUTION: This hydraulic motor comprises the fixed housing 43-45, and a rotor having a fixed position in its axial direction, a stator and a rotor supporting member for the stator, respectively mounted around one axis. Particularly the annular pressure surfaces 23a, 23b are mounted on a control unit 20 at a side facing to an axis A. The axial limit of an annular-shaped area formed between the control unit 20 and an adjacent counterpart 25 is determined by a pressure face. This counterpart 25 is held against the action of the hydraulic separation force, and engaged with the rotor to be rotated with the rotor. Whereby the balanced reaction force is generated by the transmission of the force in the rotor. By applying this structure, a bearing can be minimized.</p> |
