The above-mentioned rapid pipe joint I that is connected with outer oil cavity is arranged on the end cap, and the rapid pipe joint II that is connected with interior oil pocket is arranged on the sidewall of shrink disk outer shroud.

The invention has the beneficial effects as follows: 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 invention.

Fig. 2 is top of the present invention structure for amplifying schematic representation.

Fig. 3 is bottom of the present invention structure for amplifying schematic representation.

Wherein: ring in the 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 invention utilizes hydraulic drive band tapering

Ring 2 pushes outer shaft in the shrink disk, makes outer shaft and interior between centers that certain radial pressure be arranged, and utilizes radial pressure to finish axial torque drive in the frictional force that inside and outside between centers produces.Comprise ring 2 in shrink disk outer shroud 1 and the shrink disk, ring 2 ends are provided with flanging 5 in the shrink disk, be provided with groove on the end face of shrink disk outer shroud 1, the interior ring 2 of shrink disk is enclosed within the shrink disk outer shroud 1 and flanging 5 is embedded in the groove, groove notch place on shrink disk outer shroud 1 end face is connected with annular end cap 6, end cap 6, ring 2 surrounds groove the cavity of sealing in shrink disk outer shroud 1 and the 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 in the shrink disk, interior oil pocket 4 and outer oil cavity 7 lay respectively at inboard and the outside of flanging 5, and 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 the 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 the 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 the annular slot II 13 and with annular slot II 13 bottom bolts and is connected, and the inner peripheral surface of end cap 6 embeds in the annular slot I 9.Between the inner peripheral surface of end cap 6 and annular slot I 9 sidewalls, between flanging 5 tops and the recess sidewall and be provided with sealing gasket 8 between 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 the 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 ring 2 is subject in the outer oil cavity 7 in the shrink disk promotes to left movement, gradually lock inside and outside axle, after whole system is stable, remove oil supply system, finish 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 ring 2 is subject in the interior oil pocket 4 in the shrink disk promotes to move right, gradually make inside and outside axle see that impacting force reduces, and finally finishes dismantlement work.Fast because of the hydraulic system execution speed, the stability of a system is controlled, so this mechanism can finish quick mounting and the dismounting of shrink disk, greatly improves installation and removal efficient.

The above only is the preferred implementation of this patent; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection domain of this patent.
