Abstract
The utility model discloses a vehicular sealing ring with high sealing property and multi-lip structure, which is applied to a bearing unit with high sealing property and belongs to the field of bearing sealing. The sealing ring comprises an inner framework and a rubber body, wherein the rubber body is provided with a main lip, a first auxiliary lip and a second auxiliary lip; the main lip is in radial interference contact with a fitting piece, and the two auxiliary lips are in radial interference contact with the fitting piece respectively; and a first waist part is formed between the main lip and the first auxiliary lip, and a second waist part is formed between the first auxiliary lip and the second auxiliary lip. A cavity is defined by the first auxiliary lip, the main lip, the first waist part and the fitting piece, and lubricating grease is filled in the cavity. Through non-elastic finite element modeling (FEM) analysis, the three-lip structure comprising one main lip and two auxiliary lips is scientifically designed; and through different waist shapes and different interference magnitudes of the two auxiliary lips, alternative compensation after the two auxiliary lips are abraded is ensured, and alternative abrasion compensation of the double auxiliary lips is achieved, so that the sealing property is not reduced and the abrasion is reduced.
Description
Technical field
The utility model relates to a kind of automobile-used many procheilon of high sealing structure seal ring, is applied to the bearing unit of high leak tightness, and it belongs to the bearing seal field.
Background technique
Hub-bearing unit is to grow up on the basis of standard angle contact ball bearing and tapered roller bearing, it is made two sleeves and is one, have the assembling performance good, can omit play adjustment, in light weight, compact structure, load bearing capacity big, for stuffing box bearing can pack in advance lubricating grease, omit external hub and seal and avoid advantage such as maintenance, be widely used in the car, in truck, also had progressively to enlarge trend of application.And the development of commercial car and truck is more and more higher to the requirement of anti-muddy water, hub-bearing unit is as important rotation base part, just require the seal ring of bearing to keep very high sealability in abominable vehicle Environmental Conditions desert, rainforest, severe cold, heat etc. down, always.
Summary of the invention
In view of the defective that prior art exists, the utility model provides a kind of automobile-used many procheilon of high sealing structure seal ring, reaches the purpose of very high dustproof and anti-muddy water.
For achieving the above object, the technological scheme that the utility model adopts is a kind of automobile-used many procheilon of high sealing structure seal ring, comprises inner frame and rubber body; Rubber body is provided with main lip, the first auxiliary lip and the second auxiliary lip; Main lip contacts with the counterpart radial interference, and two auxiliary lips contact with the counterpart radial interference respectively; Being first waist between main lip and the first auxiliary lip, is second waist between the first auxiliary lip and the second auxiliary lip.The described first auxiliary lip, main lip, first waist and counterpart surround cavity, packing grease in it.The described first auxiliary lip, the second auxiliary lip, second waist and counterpart surround cavity, packing grease in it.Resolve lumbar shape and the magnitude of interference of two auxiliary lips of design, two auxiliary lip alternately compensation mutually after wearing and tearing by non-resilient FEM finite element.The first auxiliary lip is identical with the angle of inclination of the second auxiliary lip.Also can be according to concrete service condition: different with the condition of extraneous dust and muddy water etc. as the bearing internal pressure, suitably adjust the angle of the angle of two auxiliary lips, when extraneous dust and muddy water were relatively more serious, the second auxiliary labial angle degree was greater than the first auxiliary labial angle degree.In principle, the elastic deformation amount of the first auxiliary lip is less than the second auxiliary lip.
After adopting such scheme, compared with prior art has following beneficial effect: resolve by non-resilient FEM finite element, scientifically design 3 procheilon structures, comprise 1 main lip and 2 auxiliary lips, the different lumbar shape of 2 auxiliary lips and different magnitude of interference guarantee the alternately compensation mutually after wearing and tearing of 2 auxiliary lips, reach two auxiliary lips and replace wear compensation, thereby do not reduce sealing, the function of reducing friction again.
Description of drawings
Fig. 1 is a kind of schematic representation of automobile-used many procheilon of high sealing structure seal ring.
Among the figure: 1, inner frame, 2, rubber body, 3, first waist, 4, main lip, 5, the first auxiliary lip, 6, the second auxiliary lip, 7, second waist.
Embodiment
For understanding a kind of structure of automobile-used many procheilon of high sealing structure seal ring in depth, be described as follows in conjunction with Fig. 1:
A kind of automobile-used many procheilon of high sealing structure seal ring comprises inner frame 1 and rubber body 2; Rubber body 2 is provided with main lip 4, the first auxiliary lip 5 and the second auxiliary lip 6; Main lip 4 contacts with the counterpart radial interference, and two auxiliary lips contact with the counterpart radial interference respectively; Be to be second waist 7 between first waist, 3, the first auxiliary lips 5 and the second auxiliary lip 6 between main lip 4 and the first auxiliary lip 5.The described first auxiliary lip 5, main lip 4, the first waists 3 and counterpart surround cavity, packing grease in it.Described first auxiliary lip 5, the second auxiliary lip 6, the second waists 7 and counterpart surround cavity, packing grease in it.Resolve lumbar shape and the magnitude of interference of two auxiliary lips of design, two auxiliary lip alternately compensation mutually after wearing and tearing by non-resilient FEM finite element.The first auxiliary lip 5 is identical with the angle of inclination of the second auxiliary lip 6.Second auxiliary lip 6 angles are greater than the angle of inclination of the first auxiliary lip 5.The elastic deformation amount of the described first auxiliary lip 5 is less than the elastic deformation amount of the second auxiliary lip 6.
Resolve by non-resilient FEM finite element, scientifically design 3 procheilon structures, comprise 1 main lip and 2 auxiliary lips, the different lumbar shape of 2 auxiliary lips and different magnitude of interference, guarantee the alternately compensation mutually after wearing and tearing of 2 auxiliary lips, reach two auxiliary lips and replace wear compensation, thereby do not reduce sealing, the function of reducing friction again.
