Abstract
The invention discloses an automobile multiple lip structure sealing ring with high sealing performance, is applied to bearing units with high sealing performance, and belongs to the field of bearing sealing. The sealing ring comprises an internal framework and a rubber body; a main lip, a first auxiliary lip and a second auxiliary lip are arranged in the rubber body; the main lip is in radial interference contact with a fitting piece; the two auxiliary lips are in radial interference contact with the fitting piece; a first waist-shaped part is formed between the main lip and the first auxiliary lip; and a second waist-shaped part is formed between the first auxiliary lip and the second auxiliary lip. The first auxiliary lip, the main lip, the first waist-shaped part and the fitting piece form a cavity, and lubricating grease is sealed in the cavity. The three lip structures are scientifically designed through inelastic FEM (finite element method) finite element analysis, and comprises the one main lip and the two auxiliary lips, and different waist shapes and different interference amounts of the two auxiliary lips ensure that the two auxiliary lips compensate with each other alternately after being worn, so that the functions that the two auxiliary lips are alternately worn and compensate, the sealing performance is not reduced and friction is reduced are achieved.
Description
Technical field
The present invention relates to automobile-used many bead structures of high sealing seal ring, be applied to the bearing unit of high leak tightness, 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 integrated, have the assembling performance good, can omit play adjustment, lightweight, compact structure, load bearing capacity large, for stuffing box bearing can pack in advance lubricating grease, omit external hub and seal and avoid the advantage such as maintenance, be widely used in car, also had progressively to enlarge the trend of using in truck.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 component, under abominable vehicle Environmental Conditions desert, rainforest, severe cold, heat etc., just require the seal ring of bearing to keep very high sealability always.
Summary of the invention
Defective in view of prior art exists the invention provides automobile-used many bead structures of high sealing seal ring, reaches the purpose of very high dustproof and anti-muddy water.
For achieving the above object, the technical solution adopted in the present invention is automobile-used many bead structures of high sealing 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 the first waist between main lip and the first auxiliary lip, is the second waist between the first auxiliary lip and the second auxiliary lip.The described first auxiliary lip, main lip, the first waist and counterpart surround cavity, packing grease in it.The described first auxiliary lip, the second auxiliary lip, the second waist and counterpart surround cavity, packing grease in it.By non-resilient FEM finite element analysis, lumbar shape and the magnitude of interference of two auxiliary lips of design, two auxiliary lips are in wearing and tearing alternately compensation mutually afterwards.The first auxiliary lip is identical with the angle of inclination of the second auxiliary lip.Also can be according to concrete service condition: as different with the condition of extraneous dust and muddy water etc. in the bearing internal pressure, suitably adjust the angle of the angle of two auxiliary lips, when extraneous dust and muddy water were 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: by non-resilient FEM finite element analysis, scientifically design 3 bead structures, comprise 1 main lip and 2 auxiliary lips, the different lumbar shape of 2 auxiliary lips and different magnitude of interference guarantee that 2 auxiliary lips in wearing and tearing alternately compensation mutually afterwards, 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 the schematic diagram of automobile-used many bead structures of high sealing seal ring.
In figure: 1, inner frame, 2, rubber body, the 3, first waist, 4, main lip, the 5, first auxiliary lip, the 6, second auxiliary lip, the 7, second waist.
Embodiment
For understanding the structure of automobile-used many bead structures of high sealing seal ring in depth, be described as follows in conjunction with Fig. 1:
Automobile-used many bead structures of high sealing 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 the second waist 7 between the first auxiliary lip 5 of waist 3, the first 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.The described first auxiliary lip 6, the second waists 7 of auxiliary lip 5, the second and counterpart surround cavity, packing grease in it.By non-resilient FEM finite element analysis, lumbar shape and the magnitude of interference of two auxiliary lips of design, two auxiliary lips are in wearing and tearing alternately compensation mutually afterwards.The first auxiliary lip 5 is identical with the angle of inclination of the second auxiliary lip 6.The 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.
By non-resilient FEM finite element analysis, scientifically design 3 bead structures, comprise 1 main lip and 2 auxiliary lips, the different lumbar shape of 2 auxiliary lips and different magnitude of interference, guarantee that 2 auxiliary lips are in wearing and tearing alternately compensation mutually afterwards, reach two auxiliary lips and replace wear compensation, thereby do not reduce sealing, the function of reducing friction again.
