This standard defines the interface dimensions for
inch series shrouded and exposed bolt gear coupling
flanges.
1.1 Appllcabllity
This standard covers the dimensions for gear
coupling sleeve and rigid hub flange outside diameter,
bolt circle, flange width, hole size, number of
holes, hole length and counterbore diameter or
groove width for exposed and shrouded bolt gear
couplings.
The gear coupling sizes coveirne tdh is standard are:
For exposedb olt couplings: 11/2,2,21/2,3 ,3’/2,4,
4’/2, 5, 6, 7, 8 and 9.
For shrouded bolt couplings: 11/22, ,2’/2,3, 31/2,
4, 4l/2 and 5.
