Description
Technical field
The utility model relates to the universal joint sealing configuration, has related in particular to a kind of dust-proof cover universal joint of skeleton sealing configuration.
Background technique
At present, the dust-proof cover of the Hooke's joint of existing homogeneous structure, usually all be to adopt the nylon manufacturing, there is larger gap in this dust-proof cover, sealing is relatively poor, Hooke's joint when in use, dust and muddy water are easy to enter in the bearing, and the performance and used life of Hooke's joint is caused very large impact.Original nylon dust-proof cover insufficient strength causes brittle fracture easily in assembling with in using in addition.
Summary of the invention
The single nylon material that the utility model adopts for original homogeneous structure in the prior art, the shortcomings such as deficiency on intensity and dust sealing performance have been remedied, a kind of sealing, good dustproof effect are provided, the Hooke's joint of the skeleton sealing configuration dust-proof cover of interior bag that intensity is high.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The dust-proof cover universal joint of skeleton sealing configuration, comprise cross axle, be equipped with bearing outer ring on the cross-axis head of described cross axle, bearing outer ring is provided with dust-proof cover, the upper end of dust-proof cover and bearing outer ring clamping, be provided with needle roller and seal ring in the bearing outer ring, be provided with metal frame between dust-proof cover and the seal ring.
As preferably, be provided with nylon spacer between described needle roller and the seal ring.
As preferably, the elastic washer that turns in being provided with between described needle roller and the seal ring.
As preferably, described nylon spacer is provided with the circular arc oil groove.
As preferably, described dust-proof cover inboard is provided with internal projecting ring, and internal projecting ring and metal frame are connected.
As preferably, described metal frame is shaped as S shape for exposing.
The utility model is owing to adopted above technological scheme, and have significant technique effect: the dust sealing impact of performance of the utility model dust-proof cover is good, and intensity is high, makes easy to assemblyly, and profile and Hooke's joint mate, and be clean and tidy, attractive in appearance.

The toponym that each number designation refers in the above accompanying drawing is as follows: wherein 1-cross axle, 2-cross-axis head, 3-needle roller, 4-bearing outer ring, 5-seal ring, 6-nylon spacer, 7-metal frame, 8-dust-proof cover.
Embodiment
Below in conjunction with accompanying drawing 1 to Fig. 2 and embodiment the utility model is described in further detail:
Embodiment 1
The dust-proof cover universal joint of skeleton sealing configuration, as shown in Figure 1, comprise cross axle 1, be equipped with bearing outer ring 4 on the cross-axis head 2 of described cross axle 1, bearing outer ring 4 is provided with dust-proof cover 8, the upper end of dust-proof cover 8 and bearing outer ring 4 clampings are provided with needle roller 3 and seal ring 5 in the bearing outer ring 4, be provided with metal frame 7 between dust-proof cover 8 and the seal ring 5.Dust-proof cover is arranged on the cover opening end, and dust-proof cover 8 is made by the combination of metal frame and nitrile butadiene rubber, during assembling, the internal projecting ring of dust-proof cover 8 is assemblied on the buckle of metal frame 7, gets final product in the inboard aperture of the dust-proof cover 8 of then spindle nose of cross axle being packed into.By dust-proof cover 8 and metal frame 7 are set, so that the cross axle sealing and dustproof is effective, intensity is high, make the advantages such as easy to assembly.
Top, the outside is provided with internal projecting ring in the dust-proof cover, and bulge loop is stuck on the buckle of metal frame outward flanging of seal ring, makes dust-proof cover cover body good springiness, cooperates closely, has further improved the serviceability of dust-proof cover.
Be provided with nylon spacer 6 between needle roller 3 and the seal ring 5.Be provided with the elastic washer that turns in the plane between needle roller 3 and the seal ring 5.The elastic washer that turns between needle roller 3 and seal ring 5, being provided with.The cross section of elastic washer 12 tilts at an angle from inside to outside.Nylon spacer 6 is provided with the circular arc oil groove.Nylon spacer 6 its tops are provided with the circular arc oil groove, and adjacent two oil grooves extend to relative both direction radiation respectively.
Dust-proof cover 8 inboards are provided with internal projecting ring, and internal projecting ring and metal frame 7 are connected.Metal frame 7 is shaped as S shape for exposing.
Seal ring 5 is arranged in the bearing outer ring 4, is supported by S type metal frame 7, and dust-proof cover 8 is arranged on bearing outer ring 4 opening ends, and the spindle nose 2 of cross axle is close in dust-proof cover 8 inboards, and its outer inside front is provided with internal projecting ring.Simultaneously, metal frame 7 outward flangings of seal ring 5 are provided with a buckle, and the internal projecting ring on the dust-proof cover 8 cooperates with its clamping.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
