JOINTED DEVICE OF HELICAL ROTOR-DRIVEN HYDRAULIC MACHINE Russian patent published in 2004 - IPC

FIELD: helical rotor-driven hydraulic machine jointed devices engineering. SUBSTANCE: device has casing with an aperture, shaft with a spherical portion, foot with spherical surface for interacting with front side of shaft, finger and a compaction with a collar. It also has sliders with parallel side edges, which are mounted moveably in radial windows made in the casing in parallel to its axis and two half-inserts with stopping surfaces, mounted in casing aperture for interaction with through opening of the shaft, and by end portions the finger is mounted moveably in radial apertures of sliders. Compaction has a nut with a skirt for covering casing windows, stopping ring for interaction with half-inserts through adjusting ring and with a nut. EFFECT: increased loading capability, reliability and durability of jointed device. 2 cl, 3 dwg
