ABSTRACT:
A preload-clamp nut device is provided which securely mounts to a shaft having a plurality of shaft-mounted tools and provides a preload against the tools. A preferred embodiment of the device comprises a sleeve with a threaded bore and a slitted, tapered surface and a flange having a plurality of threaded holes, a clamp ring having a tapered bore and a plurality of openings that can be aligned with the plurality of threaded holes in the flange, and a plurality of bolts each having a set nut and a lock nut. When the bolts are inserted through the openings in the clamp ring into the threaded holes in the flange the set nuts and bolts can be tightened to clamp onto the shaft and preload the shaft-mounted tools. An alternative embodiment of the present invention provides a flange having a two-portion bore with a tapered portion and a constant diameter portion and a plurality of threaded holes, and a multipiece lockring having beveled edges that fit into the flange's tapered bore portion. A groove in a shaft receives the lockring. Bolts can be inserted into the flange's threaded holes and tightened to provide a preload on tools mounted onto the shaft. The preload is resisted by the groove-mounted lockring which prevents exodus of the flange from the shaft.
