How does this hub come apart?
Its likely disassembles in one of two ways:


two cone wrenches (one on each side of the hub) to remove the jam nuts. This is the likely option. From your photo it looks like there is a flat spot on the jam nut.
two hex wrenches (one on each side of the hub) that fit into the axle end.




Two videos demonstrating these techniques:
