DEVICE FOR ASSEMBLING MULTISECTION GEROTOR MECHANISMS OF SCREW HYDRAULIC MACHINES Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to manufacture of gerotor mechanisms, namely, to devices for orientated assembling of rotor and stator modules of said mechanisms. Movable bushing with outer screw surface is made for axial displacement and disconnection from rod. At least one longitudinal and one cross notches are made on outer surface of rod. Each bushing with inner screw surface is made in form of separate module. At least one longitudinal notch is made on one of bushings with inner screw surface, and on other bushing with inner screw surface longitudinal notches are made equally spaced over circumference, whose number is equal to number of starts or rotor screw surfaces. Invention improved manufacturability of device, its reliability and increases service life. Provision is made for creating constructions with inner diameters of connecting elements of stators not limited by outer diameters of device bushings owing to exclusion of rigid coupling between bushings and provision of fixed adjustment of device. EFFECT: reduced cost owing to simplification of design. 3 cl, 9 dwg
