Description
Technical Field
The utility model relates to a belt conveyor technical field especially relates to a novel bearing roller seal structure.
Background
At present, more and more belt conveyors are sold to foreign markets, although carrier rollers of the belt conveyors are easy-to-wear parts, requirements on waterproof, dustproof, rotation resistance and the like of the carrier rollers are improved, although the current carrier roller sealing structure forms in China are various, the assembly efficiency is low, the production cost is high, some waterproof and dustproof performances are poor, the service life of the carrier rollers is influenced, some rotation resistance is large, the operation power is increased, and the requirements of users cannot be well met.
Disclosure of Invention
The utility model discloses the purpose is exactly in order to compensate prior art's defect, provides a novel bearing roller seal structure.
The utility model discloses a realize through following technical scheme:
the utility model provides a novel bearing roller seal structure, including inner seal circle and external seal circle, inner seal circle and external seal circle between the hookup location department be the labyrinth structure, the upper end outside of external seal circle is equipped with circular cambered surface arch, is equipped with circular cambered surface recess in the lower extreme inboard of external seal circle, is equipped with circular recess one in the upper end inboard of external seal circle the upper end outside of inner seal circle be equipped with circular point form arch, form the gap between circular point form arch and the circular recess one, be equipped with circular recess two in the upper end inboard of inner seal circle.
The upper end surface and the lower end surface of the outer sealing ring are flush with the upper end surface and the lower end surface of the inner sealing ring.
And a steel plate gasket is arranged inside the second circular groove.
The utility model has the advantages that: the utility model discloses sealed effectual, assembly efficiency is high, and rotation resistance is little, and long service life is applicable to the waterproof, the dustproof occasion that requires highly of belt feeder bearing roller.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a bottom view of the present invention;
fig. 3 is a schematic view of the application structure of the present invention.
Detailed Description
The advantages of the utility model will be more clear through further description; this embodiment is exemplary only, and does not limit the scope of the invention; the details and the forms of the technical solution of the present invention can be modified or substituted without departing from the spirit and scope of the present invention, and the modified and substituted contents all belong to the protection scope of the present invention.
As can be seen from fig. 1 and 2, the novel carrier roller sealing structure comprises an inner sealing ring 1 and an outer sealing ring 2, wherein a labyrinth structure 3 is arranged at the connecting position between the inner sealing ring 1 and the outer sealing ring 2, a circular arc surface bulge 4 is arranged on the outer side of the upper end of the outer sealing ring 2, and the circular arc surface bulge 4 is tightly matched with an arc surface on a stamping bearing seat; a circular arc-surface groove 5 is formed in the inner side of the lower end of the outer sealing ring 2, a first circular groove 6 is formed in the inner side of the upper end of the outer sealing ring 2, a circular pointed protrusion 7 is arranged on the outer side of the upper end of the inner sealing ring 1, a gap is formed between the circular pointed protrusion 7 and the first circular groove 6, and a second circular groove 8 is formed in the inner side of the upper end of the inner sealing ring 1.
The upper end surface and the lower end surface of the outer sealing ring 2 are flush with the upper end surface and the lower end surface of the inner sealing ring 1.
And a steel plate gasket 9 is arranged inside the second circular groove 8.
As shown in fig. 3, the utility model comprises an inner sealing ring 1 and an outer sealing ring 2, wherein the outer sealing ring 2 is arranged on a carrier roller bearing seat 10, the inner sealing ring 1 is arranged on a carrier roller shaft 11, and a labyrinth seal is formed between the inner sealing ring and the outer sealing ring; the circular cambered surface bulge 4 at the upper end of the outer sealing ring 2 is tightly matched with the circular cambered surface on the stamping bearing seat 10, the sealing effect is good, the circular groove I6 at the upper end of the outer sealing ring 2 is matched with the circular pointed bulge 7 at the upper end of the inner sealing ring, and a small gap is adopted, so that the sealing effect is improved; when the outer sealing ring 2 rotates along with the carrier roller, the circular arc groove 5 at the lower end throws lubricating grease into the bearing cavity under the action of centrifugal force, so that the lubrication of the bearing 13 is improved; a steel plate gasket 9 is arranged in a circular groove II 8 at the upper end of the inner sealing ring 1, a snap spring 12 on the shaft is in contact with the steel plate gasket 9, and when the axial force is large, the snap spring 12 can be prevented from being clamped into the inner sealing ring 1; the outer end faces of the inner sealing ring 1 and the outer sealing ring 2 are flush, so that the inner sealing ring and the outer sealing ring can be pressed and mounted at one time, the respective assembly is avoided, and the assembly efficiency is improved by 1 time; the utility model discloses sealed effectual, assembly efficiency is high, and rotation resistance is little, and long service life is applicable to the waterproof, the dustproof occasion that requires highly of belt feeder bearing roller.
