<p>A taper nut retention device mechanically fastens a plurality of pressure reduction disks. A cage end member at one end of the stacked disks has a series of counterbores, each aligned with respective mounting holes in each disk. A second cage end member at the other end of the stack has a series of inwardly converging, tapered bores with shallow taper angles, each aligned with respective mounting holes and a counterbore. A taper nut with a threaded interior and an outer tapered surface with a shallow taper angle matching the tapered bore is inserted into and engageably contacts the tapered bore. A threaded bolt is inserted into the counterbore and through the disk mounting holes to threadably engage the taper nut. Tightening of the bolt and nut mechanically secures the stacked disk assembly. A process for making the stacked disk assembly wherein each disk and the cage end members are plated with nickel and the components are fused together in a brazing oven. The taper nuts are then inserted in each tapered bore and engaged with a threaded bolt.</p> |
