GEAR HYDRAULIC MACHINE Russian patent published in 1995 - IPC

FIELD: agricultural machines. SUBSTANCE: overhanging parts of radial sealing member rest on trunnions of external meshing gear. End face sealing members adjoin the gears. Placed in cylindrical recesses of bearing unit are antifriction shells in which trunnions are installed. End faces of shells and overhanging parts of member found on external sides of trunnions, relative to pitch point, conjugate over entire area of shell end face edges overlapped by overhanging parts. Clearance is formed between other ends of shells and end face sealing members. Overhanging parts rest on trunnions over surfaces of trunnions within the limits of left length, starting from rear surface of members. Angle at which shells embrace trunnions is within 115 and 120 degrees. EFFECT: enlarged operating capabilities. 2 cl, 3 dwg
