State and be provided with the flange of flange nut screwed hole corresponding with each otch, the oval styletable of each screwed hole adaptation fluting is tight
Determine screw, in two screws being screwed into by using two oval styletable holding screws of fluting on the flange of flange nut, rotate tight
Determine the notch step that screw withstands cylindrical nut, the adjustment of pretension can be realized when promoting cylindrical nut rotation.
Preferably, the cylindrical nut, flange nut are also equipped with dust ring with the ball-screw junction, and
The dust ring is embedded in the seal groove of the cylindrical nut and flange nut.
Preferably, threaded connection hole is provided with the cylindrical nut and the flange nut, each screw thread
Adaptation fluting tapered end holding screw in connecting hole.
Preferably, the angle of the otch is 105, and the otch is integrally made up of vertical edges and inclined side, described
The end of the vertical edges correspondence oval styletable holding screw of fluting.
Preferably, the cylindrical nut, flange nut pass through helicla flute, steel ball and reverser with the ball-screw
Connection.
The beneficial effects of the utility model are：Compared with prior art, the utility model has the advantages that, nut structure is tight
Gather, assembling is easy, pretightning force is easy to adjust, reliable, the low advantage of long service life, production cost.
