GEAR REVERSING HYDRO-MACHINE

摘要

A gear reversing hydro-machine has driving and driven pinions of external engagement placed in the inner chamber of the housing of hydro-machine formed with cylindrical bores that intersect. At least one end tightening element is pressed to the ends of the pinions and has compensation chamber at notoperating end of sealing element formed mostly with slots as number "8" sealed with elastic sleeve with protecting elements. The sleeve surrounds the openings for pinion pins and adjoins opposite walls of the inner chamber of the housing at different sides of the pole of pinion engagement. Hydro-machine has supply channels to compensation chamber. The compensation chamber in the place of slot adjoining opposite walls of the housing inner chamber placement has arc-like elongations separated with link from slots surrounding openings for pinion pins and going along the walls of cylindrical bores of the housing inner chamber to the side of intersection of those. At such re-distribution of area of compensation chamber arc-like elongations tighten with reliability sickle-shaped slots between the outer surface of compensators and the inner chamber of the housing, and improve volumetric efficiency.
