Rotary casing orbital gear-rotor motor

Abstract

Abstract AXIALLY-SPACED STATIONARY INLET AND OUTLET SHAFTS ARE HELD AGAINST ROTATION AND PROVIDED WITH LONGITUDINAL INLET AND OUTLET PASSAGEWAYS LEADING TO CIRCUMFERENTIALLYSPACED RADIAL FLUID INLET AND OUTLET PASSAGEWAYS WHICH IN TURN COMMUNICATE SUCCESSIVELY WITH CIRCUMFERENTIALLYSPACED LONGITUDINAL FLUID INLET AND OUTLET PASSAGEWAYS IN AXIALLY-SPACED ROTARY FLUID-DISTRIBUTING INLET AND OUTLET BARRELS DISPOSED ON OPPOSITE SIDES OF AND DRIVENGLY CONNECTED TO AN INTERNALLY-TOOTHED OUTER ROTOR WHICH MESHES WITH AND SURROUNDS AN EXTERNALLY-TOOTHED INNER STATOR WHICH IS INTERNALLY-SPLINED AND COUPLED TO THE STATIONARY SHAFTS BY A PAIR OF DOUBLE-HEADED EXTERNALLY-SPLINED DRIVE LINKS WHICH OSCILLATE BUT DO NOT ROTATE WHILE MESHING WITH INTERNALLY-SPLINED BORES IN THE STATIONARY SHAFTS. A SINGLE DRIVE LINK MAY BE USED IN LOW-TORQUE MOTORS SINCE THE TWO SHAFTS ARE HELD AGAINST ROTATION IN PROPER PHASE RELATIONSHIP BY THEIR INTERCONNECTING FRAME STRUCTURE. HYDRAULIC PRESSURE FLUID IS SUPPLIED TO THE STATIONARY INLET SHAFT AND DISCHARGED SUCCESSIVELY THROUGH THE LONGITUDINAL INPUT BARREL PASSAGEWAYS INTO THE SUCCESSIVELY EXPANDING AND CONTRACTING FLUID CHAMBERS BETWEEN THE TEETH OF THE STATOR AND ROTOR, THEREBY IMPARTING ROTATION TO THE INTERNALLY-TOOTHED OUTER ROTOR AND THENCE TO THE REMAINDER OF THE CASING CONSISTING OF THE TWO BARRELS AND OUTER ROTOR. THE CASING THEREUPON BECOMES A DRIVE PULLEY CAPABLE OF DRIVING A BELT DIRECTLY OR CAPABLE OF CARRYING ANOTHER DRIVING MEMBER, SUCH AS A GEAR, SPROCKET, CAM OR WHEEL. THE FLUID FROM THE GEAR-ROTOR MOTOR THUS CONSTITUTED IS DISCHARGED THROUGH THE OUTLET BARREL AND HOLLOW OUTLET SHAFT. THIS MOTOR IS ESPECIALLY VALUABLE WHERE SPACE IS AT A PREMIUM AND EXTREME COMPACTNESS IS DESIRED AND REQUIRED.
