Specific embodiment
The technical solution of the application is described in detail below with reference to specific view.
Embodiment 1
As shown in Figure 1, Feed Manufacturing auger sealing device, including sealing axis 1, axle sleeve 2, end cap 5, seal the outer of axis 1
Side is arranged axle sleeve 2, and the base portion of end cap 5 and the corresponding position of axle sleeve 2 are embedded with packing set 3, and the end cap 5 with packing set 3 screws
Sealing separate space is formed in the outer end of sealing axis 1, between end cap 5 and axle sleeve 2, is sealed and is circumferentially arranged on the sealing axis 1 of separate space
It is provided with annular groove, packing set 3 is located in groove, and the endface that end cap 5 and packing 4 are in contact is provided with card slot, and card slot is opened
Mouth end is fastened on 4 outer wall of packing；The locking of end cap 5 control packing 4 and sealing axis 1 are in close contact.
The hollow cone cylinder body structure that card slot is extended as diameter gradual-enlargement type from base portion to open end, card slot open end
Internal diameter it is consistent with the outer diameter of packing 4.Internal diameter<sealing axis 1 of the outer diameter of packing 4>sealing axis 1 diameter, packing 4 is straight
Diameter, internal diameter >=annular groove diameter of packing 4.
When specific installation, first packing set 3 is located in the groove of sealing axis 1, plays the role of tentatively engaging, by end cap 5
It being screwed along one end of sealing axis 1, card slot and the packing 4 of end cap 5 contact with each other, as end cap 5 inwardly screws propulsion, end
The card slot of lid 5 and the outer wall of packing 4 fit closely, and the special construction of card slot forms certain clamping to the side wall of packing 4
Power, i.e., extruding force certain to packing 4 along the direction perpendicular to sealing axis 1, subtracts packing 4 and the spacing sealed between axis 1
It is small, improve sealing performance between the two.
Embodiment 2
On the basis of embodiment 1, it is different from embodiment 1, as shown in figure 3, packing 4 is set as annular coil structures, packing 4
Anti-skid bulge 6 is provided on inner wall corresponding with annular groove, the anti-skid bulge 6 is made of the braiding of expanded graphite line
Sector structure, the equidistant arrangement setting in a ring of adjacent anti-skid bulge 6.
Anti-skid bulge 6 contacts with each other with sealing axis 1, forms sealed airspace between adjacent protection protrusion and sealing axis 1, when
When packing 4 is by along perpendicular to the extruding force for sealing 1 axially direction of axis, sealed airspace is compressed, anti-skid bulge 6 and sealing
Contact area between axis 1 increases, and frictional resistance between the two becomes larger, and the position-limiting action of packing 4 is preferable, is not susceptible to shift
Phenomenon plays good sealing performance.
The middle part of packing 4 is provided with hollow ring air bag 7.Packing 4 have certain elastic buffer effect, in the middle part of ring
Shape air bag 7 can increase its elastic deformation, since the material inside and outside annular air-pocket 7 is higher relative to sealing ring hardness, make
Packing 4 has wear-resisting characteristic, can effectively improve sealing life；Certain protective action is formed to annular air-pocket 7, when end cap 5
When forming certain pressure to packing 4, packing 4 plays the role of deformation in corresponding deformation range, increases contact area, both
Meet certain elastic packing demand, and compressive resistance can be improved.
Packing set 3 is set as hollow ring disc structure, and the lateral wall of packing set 3 is provided with reinforcement block, and reinforcement block includes
The concave surface layer to fit with end cap 5 and the convex surface layer to fit with axle sleeve 2, reinforcement block using the preparation of hardness higher steel material and
At.Reinforcement block is added, and can be reduced the deformation effect of packing set 3, be improved compressive resistance.The hardness of packing set 3 is greater than the hard of packing 4
Degree, is fastened in end cap 5, plays the role of fixed, support and limit, while guaranteeing enough sealing performances, prevents disk
4 deformation of root is excessive, extends the service life of sealing device.
The above is not limitation of the present invention, it should be pointed out that: those skilled in the art are come
It says, under the premise of not departing from essential scope of the present invention, several variations, modifications, additions or substitutions can also be made, these improvement
It also should be regarded as protection scope of the present invention with retouching.
