For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of combined seal ring, can have very good sealing effect and have longer working life.
For achieving the above object, the utility model provides following technological scheme: a kind of combined seal ring, the metallic packing ring comprising exterior seal ring, inner seal ring and be folded between exterior seal ring and inner seal ring, described exterior seal ring and inner seal ring all with outer ring clamping, the inner ring interference fit of described metallic packing ring and bearing.
Preferably, described metallic packing ring and inner seal ring are rotationally connected, and described exterior seal ring abuts with metallic packing ring and arranges.
Preferably, described inner seal ring is provided with the first sealing lip, and described metallic packing ring is provided with the scrobicular ring of accommodation first sealing lip.
Preferably, described first sealing lip is arranged with annular spring.
Preferably, described exterior seal ring is provided with the second sealing lip abutted with inner ring.
Preferably, described exterior seal ring and inner seal ring are equipped with the Steel Bracket of ring-type.
Preferably, described exterior seal ring is provided with the annular deep gouge coordinated with metallic packing ring.
By adopting technique scheme, by arranging inner seal ring, exterior seal ring and metallic packing ring, assemble complete after, metallic packing ring and bearing inner race interference fit, metallic packing ring is folded between exterior seal ring and inner seal ring, arrange three-layer sealed, form a kind of mazy sealed environment, compared to only just arranging individual layer seal ring to seal, very good sealing effect can be played, and, metallic packing ring and inner ring are interference fit, metallic packing ring can be followed inner ring and be rotated together, because the area of contact between metallic packing ring and inner seal ring and exterior seal ring is larger, wearing and tearing between such three are very low, extend the working life of combined seal ring.

Embodiment
Referring to figs. 1 through Fig. 5, the utility model combined seal ring embodiment is described further.
A kind of combined seal ring, comprise exterior seal ring 1, inner seal ring 3 and the metallic packing ring 2 be folded between exterior seal ring 1 and inner seal ring 3, exterior seal ring 1 and inner seal ring 3 are equipped with the Steel Bracket 5 of ring-type, Steel Bracket 5 can be played a supporting role to inner seal ring 3 and exterior seal ring 1, improve the structural strength of exterior seal ring 1 and inner seal ring 3, exterior seal ring 1 and inner seal ring 3 all with outer ring clamping, the inner ring interference fit of metallic packing ring 2 and bearing, after assembling is complete, metallic packing ring 2 is followed inner ring and is rotated together, metallic packing ring 2 can play very good sealing effect.The impurity such as liquid or dust is avoided to enter Bearing inner between inner ring and metallic packing ring 2, inner seal ring 3 and exterior seal ring 1 all with bearing outer ring clamping, after installing, inner seal ring 3 and exterior seal ring 1 can be followed bearing outer ring and be rotated together, can effectively prevent liquid or dust from entering inner bearing inside between outer ring and inner seal ring 3 or between outer ring and exterior seal ring 1.
By arranging inner seal ring 3, exterior seal ring 1 and metallic packing ring 2, assemble complete after, metallic packing ring 2 and bearing inner race interference fit, metallic packing ring 2 is folded between exterior seal ring 1 and inner seal ring 3, arrange three-layer sealed, form a kind of mazy sealed environment, compared to only just arranging individual layer seal ring to seal, very good sealing effect can be played, and, metallic packing ring 2 and inner ring are interference fit, metallic packing ring 2 can be followed inner ring and be rotated together, because the area of contact between metallic packing ring 2 and inner seal ring 3 and exterior seal ring 1 is larger, wearing and tearing between such three are very low, extend the working life of combined seal ring.
When bearing rotates, when metallic packing ring 2 rotates respectively with inner seal ring 3, because metallic packing ring 2 and inner seal ring 3 are rotationally connected, the friction of metallic packing ring 2 and inner seal ring 3 can be reduced like this, reduce the wearing and tearing of inner seal ring 3, extend the working life of combined seal ring, exterior seal ring 1 abuts with metallic packing ring 2 and arranges, exterior seal ring 1 is arranged on outermost, after exterior seal ring 1 and outer ring clamping, exterior seal ring 1 can play the effect of location, avoids metallic packing ring 2 to be shifted, falls down from outer ring.
Inner seal ring 3 is provided with the first sealing lip 31, metallic packing ring 2 is provided with the scrobicular ring 21 of accommodation first sealing lip 31, assemble complete after, first sealing lip 31 puts into scrobicular ring 21, realize being rotationally connected of inner seal ring 3 and metallic packing ring 2, keep abutting with metallic packing ring 2 to make the first sealing lip 31, first sealing lip 31 is arranged with annular spring 4, annular spring 4 can tighten up the first sealing lip 31, after the first sealing lip 31 weares and teares, annular spring 4 can make the first sealing lip 31 and O-ring seal keep abutting, ensure that sealing effect, assemble complete after, inner seal ring 3 coordinates with metallic packing ring 2, be similar to labyrinth sealing, serve very good sealing effect, dust and water etc. is effectively prevented to enter Bearing inner, and the wearing and tearing of inner seal ring 3 can be reduced, extend the working life of inner seal ring 3.
In order to further promote the sealing effect of combined seal ring, exterior seal ring 1 is provided with the second sealing lip 11 abutted with the inner ring of bearing, the structure of the second sealing lip 11 and the similar of existing seal ring, the second sealing lip 11 on exterior seal ring 1 seals as first, inner seal ring 3 seals as second with the combination of metallic packing ring 2, greatly improve the sealing effect of combined seal ring, and, although be provided with multiple-sealed, but very large frictional force can not be produced between combined seal ring and bearing inner race and outer ring, can not impact the rotation of bearing, in order to make the limit effect of exterior seal ring 1 better, exterior seal ring 1 is provided with the annular deep gouge 6 coordinated with metallic packing ring 2, metallic packing ring 2 rotates in annular deep gouge 6, ring deep gouge is set, the fiting effect between exterior seal ring 1 and metallic packing ring 2 can be made better, exterior seal ring 1 can be more stable realize the spacing of metal o-ring.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
