Flange Coupling and it Types

Flange Coupling and it Types Points : Flange Coupling, types of Flange Coupling Flange coupling generally apply to coupling have two divide cast iron flanges. Every flange is mount on shaft end with keyed to it. Faces are turned up at right angle to axis of shaft. One of the flanges has a predictable part with the other flange has a matching recess. The two flanges are joined mutually by means of bolts with nuts. Flange coupling is adopted to heavy loads with thus it is use on large shafting. Types of flange coupling are given below.
1. Protected Type Flange Coupling
2. Unprotected Type Flange Coupling
3. Marine Type Flange Coupling
1. Protected Type Flange Coupling Protected type flange coupling the protrude bolts with nuts are confined by flanges on two halves of coupling, in order to evade hazard to workman. The other extents of coupling are similar as for unprotected kind flange coupling. 2. Unprotected Type Flange Coupling Undefended kind flange coupling every shaft is key to boss of flange by a counter sunk key with flanges are attached jointly by means of bolts. Commonly, three, four or six bolts are use. The keys are stagger at right angle beside the perimeter of shafts in order to separate weakening effect cause by keyways. 3. Marine Type Flange Coupling Marine type flange coupling, flanges are forged integral by the shafts. Flanges are held jointly by means of tapered headless bolts, numbering as of four to twelve depending upon diameter of shaft.
