Abstract
The utility model relates to rollers, in particular to a non-contact sealing roller seal. The problem of roller sealing is solved by the non-contact sealing roller seal. The non-contact sealing roller seal comprises a shaft, a tube body, a bearing, an inner check ring, a hole elastic check ring, an outer labyrinth seal and an inner labyrinth seal. The shaft is sleeved with the tube body, the bearing is arranged between the shaft and the tube body, the inner check ring and the hole elastic check ring are arranged on the inner side of the bearing, and the outer labyrinth seal and the inner labyrinth seal are arranged on the outer side of the bearing. A sealing cover is arranged on the outer side of the outer labyrinth seal, a protecting cover is arranged on the outer side of the sealing cover, the cross section of the sealing cover is in a Z shape, a labyrinth groove is formed in the inner side of the protecting cover, the sealing cover and the protecting cover are combined to be of a labyrinth sealing structure, and the check ring is arranged on the outer side of the protective cover in a sleeved mode. The non-contact sealing roller seal greatly prolongs the service life of a roller.
Description
Technical field
The utility model relates to a kind of carrying roller, is specially a kind of non-contacting seal supporting roller sealing.
Background technology
Carrying roller is the heart of ribbon conveyer, and its water proof and dust proof especially prevents that the sealing property of half flowing power object (such as sposh etc.) pollution from directly determining the life-span of carrying roller.The factors such as the positional precision at Idler bearing two ends, rotational resistance, rotor inertia, the corrosion prevention of operation noise, rust protection, wear resisting property bring direct impact all to the operation of belt conveyer, in order to improve the Combination property of carrying roller, we are badly in need of the hermetically-sealed construction of carrying roller to carry out brand-new design, adopting maze-type structure is the main thought in carrying roller design, adopts the design of maze-type structure very many in existing disclosed data.The gap of existing labyrinth seal structure is all exposed to outside, when carrying roller operation, trickle, dust, sposh are all easy to be drilled in labyrinth seal structure along gap, as long as pollutants has entered first labyrinth, will extend inwards, bearing can be stuck very soon, causes carrying roller to damage too early inefficacy.
Summary of the invention
The utility model, in order to solve the problem of roller sealing, provides a kind of non-contacting seal supporting roller sealing.
The technical solution of the utility model is, a kind of non-contacting seal supporting roller sealing, structure comprises axle, body, bearing, inner shield ring, circlip for bore, outer labyrinth seal, interior labyrinth seal, on axle, cover has body, it between axle and body, is bearing, bearing inner side is inner shield ring and circlip for bore, bearing outside is outer labyrinth seal, interior labyrinth seal, the outside of labyrinth seal is outside provided with seal cover cap, seal cover cap outside is protective cover, described seal cover cap section form is Z-shaped, the inner side of protective cover is provided with maze trough, seal cover cap and protective cover are combined as labyrinth seal structure, be arranged with back-up ring in protective cover outside.
Compared with prior art, the utility model is on existing labyrinth seal structure basis, increase again a labyrinth seal structure in bearing seat outside, be the labyrinth seal structure of seal cover cap and protective cover composition, make sealing effectiveness more reliable, filling lubricating grease in this structure, on simulation intensive test platform, do trickle and dust-proof test, performance all exceedes national standard, and in actual use, sealing structure has extended the service life of carrying roller greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
In figure: labyrinth seal in 1-circlip for shaft, 2-protective cover, 3-seal cover cap, the outer labyrinth seal of 4-, 5-, 6-bearing, 7-inner shield ring, 8-circlip for bore, 9-axle, 10-body.
The specific embodiment
As schematically shown in Figure 1, a kind of non-contacting seal supporting roller sealing, structure comprises axle 9, body 10, bearing 6, inner shield ring 7, circlip for bore 8, outer labyrinth seal 4, interior labyrinth seal 5, on axle 9, cover has body 10, it between axle and body, is bearing 6, bearing 6 inner sides are inner shield ring 7 and circlip for bore 8, bearing 6 outsides are outer labyrinth seal 4, interior labyrinth seal 5, 4 outsides of labyrinth seal are outside provided with seal cover cap 3, seal cover cap 3 outsides are protective cover 2, described seal cover cap 3 section forms are Z-shaped, the inner side of protective cover 2 is provided with maze trough, seal cover cap 3 and protective cover 2 are combined as labyrinth seal structure, be arranged with circlip for shaft 1 in protective cover 2 outsides.
The labyrinth ring grafting that the inner side of protective cover 2 is provided with the inner side of maze trough and seal cover cap 3 forms hermetically-sealed construction.Described seal cover cap 3 is irony seal cover cap, and described protective cover 2 is E-metal protective cover.These two kinds of parts adopt metallic materials to make its shape shape that remains unchanged, and effectively prevent that pollutants from passing.
