Description
Technical field
The utility model relates to machine tool accessory technical field, specifically a kind of new-type rotating sealing device.
Background technique
At present, the dust and water protection sealing of existing running shaft mainly adopts felt seal, labyrinth seal or oil sealing sealing.Felt seal in order to the large liquid of packing grease, oil, viscosity and dust-proof, but very undesirable for the cutting fluid sealing effect of intermetallic composite coating.Labyrinth seal is applicable at a high speed, cannot realize sealing effect when low speed and stopping.
Oil sealing sealing has strict requirement for the linear velocity of running shaft, and there are wearing and tearing, needs periodic replacement.
Model utility content
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provides a kind of novel structure, significant sealing affection, long service life, without wearing and tearing, Maintenance free, easy to maintenance, the new-type rotating sealing device that can be used for the hydraulic seal sealing various solid impurity or different viscosities.
The utility model solves the technological scheme that its technical problem adopts:
A kind of new-type rotating sealing device, comprise housing, running shaft, seal ring and sealing gland, running shaft end in described housing is arranged with seal ring and sealing gland from inside to outside successively, it is characterized in that described seal ring is made up of outer ring body and inner ring body, described outer ring body and inner ring body concentric gap fit, described outer ring body inwall is provided with taper bulge loop and taper inner groovy vertically successively, described inner ring body outer wall is provided with the outer groove of taper and tapered flanges vertically successively, described taper bulge loop and the outer groove Spielpassung of taper, described taper inner groovy and tapered flanges Spielpassung, to make the taper bulge loop between outer ring body and inner ring body, groove inside and outside taper inner groovy and taper, tapered flanges forms " W " shape sealed groove, be beneficial to not produce friction when rotating, liquid and dust is avoided to enter mechanical device inside.
The utility model can be provided with plural oil-collecting blind hole at described inner ring body outer wall circumference uniform distribution, described outer ring body sidewall circumference uniform distribution is provided with plural oil extraction through hole, described oil-collecting blind hole is corresponding with oil extraction through hole, the outer ring body mounting hole inwall of described housing is provided with annular oil-collecting groove and oil drainage hole, described oil drainage hole is connected with annular oil-collecting groove, described oil drainage hole center and horizontal plane, be beneficial to will to enter into inner ring body by gland gap and outer ring body passes through centrifugal action, make fluid and a small amount of impurity through oil extraction through hole, annular oil-collecting groove and oil drainage hole are discharged, significantly improve sealability and dustproof and waterproof performance.
The utility model due to adopt said structure, have novel structure, significant sealing affection, long service life, without wearing and tearing, Maintenance free, easy to maintenance, can be used for sealing the advantages such as various solid impurity or different viscosities.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference character:.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in drawings, a kind of new-type rotating sealing device, comprise housing 1, running shaft 4, seal ring and sealing gland 5, running shaft 4 end in described housing 1 is arranged with seal ring and sealing gland 5 from inside to outside successively, it is characterized in that described seal ring is made up of outer ring body 2 and inner ring body 3, described outer ring body 2 and inner ring body 3 concentric gap fit, described outer ring body 2 inwall is provided with taper bulge loop and taper inner groovy vertically successively, described inner ring body 3 outer wall is provided with the outer groove of taper and tapered flanges vertically successively, described taper bulge loop and the outer groove Spielpassung of taper, described taper inner groovy and tapered flanges Spielpassung, to make the taper bulge loop between outer ring body 2 and inner ring body 3, groove inside and outside taper inner groovy and taper, tapered flanges forms " W " shape sealed groove, be beneficial to not produce friction when rotating, liquid and dust is avoided to enter mechanical device inside.
The utility model can be provided with plural oil-collecting blind hole at described inner ring body 3 outer wall circumference uniform distribution, described outer ring body 2 sidewall circumference uniform distribution is provided with plural oil extraction through hole, described oil-collecting blind hole is corresponding with oil extraction through hole, the outer ring body mounting hole inwall of described housing is provided with annular oil-collecting groove and oil drainage hole, described oil drainage hole is connected with annular oil-collecting groove, described oil drainage hole center and horizontal plane, be beneficial to will to enter into inner ring body by gland gap and outer ring body passes through centrifugal action, make fluid and a small amount of impurity through oil extraction through hole, annular oil-collecting groove and oil drainage hole are discharged, significantly improve sealability and dustproof and waterproof performance.
The utility model is when high speed or low speed rotation, inner ring body drives through running shaft and does at a high speed or low speed rotation, when dust or fluid enter into seal ring through the gap of gland periphery, because the sealed groove between the inner ring body of seal ring and outer ring body is in " W " shape, under the action of the centrifugal, in the oil-collecting blind hole gathering inner ring body and outer ring body along sealed groove and oil extraction through hole, and be discharged in the annular oil-collecting groove in housing by oil extraction through hole, under gravity, discharged by oil drainage hole.
The utility model when mounted, as shown in Figure 1, first the outer ring body 2 of rotating seal ring and inner ring body 3 are installed on running shaft 4, then by running shaft 4, outer ring body 2 is installed in the hole of housing 1 together with inner ring body 3, adjust the axial position of running shaft 4 and fix, guarantee not rub when rotating between outer ring body 2 and inner ring body 3, finally gland 5 is installed on running shaft 4, compress inner ring body 3,, rotating seal ring is with regard to installation.
The utility model due to adopt said structure, have novel structure, significant sealing affection, long service life, without wearing and tearing, Maintenance free, easy to maintenance, can be used for sealing the advantages such as various solid impurity or different viscosities.
