Gesilco Coupling Design

The standard design, patented Gesilco Butterfly “BF” coupling (Fig.1) consists of two membranes, an intermediate shaft and two flanges. Membranes, intermediate shafts and flanges are manufactured as a single piece, advanced composite structure. The halves of the coupling are bolted together at the flanges with fitted bolts. By use of variable thickness spacers, installation tolerances and centering recess can be compensated. At the inner radius of the membranes fitted steel ring inserts into drilled holes are foreseen. Pre-stressed screws are used to connect the membranes to the driving and driven components.
