The beneficial effects of the utility model are: utilize hydraulic pressure that shrink disk is fastening, can realize quick mounting and the dismounting of shrink disk, greatly improve installation and removal efficient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model top structure for amplifying schematic diagram.
Fig. 3 is the utility model bottom structure for amplifying schematic diagram.
Wherein: ring in 1 shrink disk outer shroud, 2 shrink disk, 3 annular guide ledges, 4 interior oil pockets, 5 flangings, 6 end caps, 7 outer oil cavities, 8 sealing gaskets, 9 annular slot I, 10 annular outer platforms, 11 quick release coupling I, 12 annular inner convex platforms, 13 annular slot II, 14 quick release coupling II.
Embodiment
As shown in Figure 1, 2, 3, a kind of hydraulic retract dish of the present utility model utilizes hydraulic drive band tapering
In shrink disk, ring 2 pushes outer shaft, makes outer shaft and interior between centers that certain radial pressure be arranged, and utilizes radial pressure to complete axial torque drive in the frictional force that inside and outside between centers produces.comprise ring 2 in shrink disk outer shroud 1 and shrink disk, in shrink disk, ring 2 ends are provided with flanging 5, be provided with groove on the end face of shrink disk outer shroud 1, the interior ring 2 of shrink disk is enclosed within shrink disk outer shroud 1 and flanging 5 is embedded in groove, groove notch place on shrink disk outer shroud 1 end face is connected with annular end cap 6, end cap 6, in shrink disk outer shroud 1 and shrink disk, ring 2 surrounds groove the cavity of sealing, in shrink disk, the flanging 5 of ring 2 has been divided into interior oil pocket 4 and outer oil cavity 7 independent sealed and that be not connected with cavity, interior oil pocket 4 and outer oil cavity 7 lay respectively at inboard and the outside of flanging 5, interior oil pocket 4 and outer oil cavity 7 all are connected with quick release coupling.
Specifically, flanging 5 middle parts of ring 2 are outward extended with annular outer platform 10 and have extended internally annular inner convex platform 12 in shrink disk, the flanging 5 bottoms annular slot I 9 that caved inward, the groove notch of shrink disk outer shroud 1 is to having extended out annular slot II 13, middle part at the bottom of groove is outward extended with annular guide ledges 3, end cap 6 cross sections are L shaped, the outer peripheral surface of end cap 6 embeds in annular slot II 13 and is connected with annular slot II 13 bottom bolts, and the inner peripheral surface of end cap 6 embeds in annular slot I 9.Between the inner peripheral surface of end cap 6 and annular slot I 9 sidewalls, be provided with sealing gasket 8 between between flanging 5 tops and recess sidewall and annular guide ledges 3 bottoms and annular inner convex platform 12 tops.The rapid pipe joint that is connected with outer oil cavity 7 is arranged on end cap 6, and the rapid pipe joint that is connected with interior oil pocket 4 is arranged on the sidewall of shrink disk outer shroud 1.
When the inside and outside axle of connection is installed, the pre-set system pressure value of hydraulic oil supply system, connect quick release coupling I 11 and quick release coupling II 14, system gives outer oil cavity 7 fuel feeding by quick release coupling I 11, gives interior oil pocket 4 emptyings by quick release coupling II 14, and the hydraulic oil that in shrink disk, ring 2 is subject in outer oil cavity 7 promotes to left movement, gradually lock inside and outside axle, after whole system is stable, remove oil supply system, complete installation.Otherwise, when installation will be dismantled inside and outside axle, the pre-set system pressure value of oil supply system, connect quick release coupling I 11 and quick release coupling II 14, system gives outer oil cavity 7 emptyings by quick release coupling I 11, gives interior oil pocket 4 fuel feeding by quick release coupling II 14, and the hydraulic oil that in shrink disk, ring 2 is subject in interior oil pocket 4 promotes to move right, gradually make inside and outside axle see that impacting force reduces, and finally completes dismantlement work.Fast because of the hydraulic system execution speed, the stability of a system is controlled, so this mechanism can complete quick mounting and the dismounting of shrink disk, greatly improves installation and removal efficient.
