FLEXIBLE COUPLING FOR SHAFTS Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: flexible coupling comprises four flanges interconnected repeatedly in pair by means of flexible plates through tightening bolts, washers, and nuts over the periphery of the flanges. At the edges of the coupling each of two flanges is made in block with the hub. At the middle part of the coupling two flanges are made in block with the common hub. Between the two flanges is a set of flexible plates which is made of an individual unit and secured with the use of the hollow bushings. From the side of the flexible plates, each of the flanges is provided with projections made of two segments. The distance between each pair of projections on each flange exceeds the maximum height and diameter of the hollow bushings. The distance between the faces of the projections of adjacent flanges is 0.05-0.55 of the thickness of the stack of flexible plates when the stack is compressed by 50-150 kgf. The flanges have staggered openings for permitting the heads of the tightening bolt to pass through the openings.

EFFECT: simplified assembling and disassembling.
