COMPENSATING SLEEVE Russian patent published in 2007 - IPC F16D3/78 F16D3/72 

FIELD: mechanical engineering, possible use in drive of high pressure fuel pump of diesel engine during its calibration on testing stand.

SUBSTANCE: sleeve contains driving 2 and driven 3 half-couplings, rigidly held respectively on driving 1 and driven shafts. Spacer 4 is connected to each half-coupling by means of appropriate pack 5,6 of circular plates, which are positioned perpendicularly to axis of appropriate half-coupling. Aforementioned packs are connected each to its own half-coupling and to spacer 4 in points alternating along circle of plates. Half-coupling 2 is made with cylindrical shelf 21, positioned coaxially to rotation axis of this half-coupling 2. Spacer 4 is made with cylindrical aperture 22, which is positioned coaxially to axis of rotation of spacer 4 and which envelopes cylindrical shelf 21 with a gap, along the circle, perpendicular to axis of rotation of spacer 4, to provide for possible interaction of shelf 21 and aperture 22 in process of acceleration of driving shaft 1 to high speeds. Diameter of shelf 21 exceeds diameter of aperture 22 by 1-2 millimeters. Shelf 21 is made with through threaded aperture positioned along the axis of rotation of half-coupling 2, to ensure possible screwing of screw detachable device for lifting half-coupling 2 from driving shaft 1 into this aperture. Half-coupling 3 is made with through central aperture 16 positioned along its rotation axis, for simplifying access of screw detachable device to aperture of shelf 21.

EFFECT: ensured safety of sleeve structure when driving shaft is at high speeds, over 1000 turns per minute.
