Description
Technical field
The utility model relates to bearing sealed ring technical fields, specially low torque automotive hub bearing sealing ring.
Background technique
Bearing sealed ring, a kind of bearing seal, especially a kind of ball bearing sealing ring, ball bearing sealing ring be
Two are upwardly extended on one end face of circular ring shape into circular protrusion, the internal diameter and ball of the lesser protrusion of the diameter
The inner ring outer diameter of bearing matches, and the protrusion being relatively large in diameter is matched with the ball circle outer diameter of ball bearing: described
The internal orifice dimension of sealing ring is not less than the internal orifice dimension of ball bearing inner ring, and with preventing, grease is on fire, avoids often oiling and structure
The features such as simple, is widely used on bearing.
Existing automotive hub sealing ring can only be simple guarantee hub bearing normal operation circumstances, Seal Design is only
From the angle of axially and radially more lipped joint touching sealings, dustproof lip and water fender are in 25 degree to 30 degree, are not accounted for
When in use to product, running car when due to sealing ring and drip ring frictional force it is larger, the waist thickness of main lip is lower, elasticity
Poor, the enclasping force of automobile shafts is larger, and the larger environmental pollution of oil consumption increases, and energy-saving and emission-reduction state effect is poor, for this purpose, we
It is proposed low torque automotive hub bearing sealing ring.
Utility model content
The purpose of this utility model is to provide low torque automotive hub bearing sealing rings, to solve in above-mentioned background technique
The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions: low torque automotive hub bearing sealing ring, packet
Cyclic annular fixed skeleton, rubber pad, dustproof lip, main lip, grease proofing lip and drip ring are included, the cyclic annular fixed skeleton is located at bearing outer ring
Inside, and cyclic annular fixed skeleton section is L shape, is fixed with rubber pad, the rubber pad on the inside of the cyclic annular fixed skeleton L shape
Top dustproof lip, the rubber pad side is equipped with main lip, and bottom is equipped with grease proofing lip, and the rubber pad side is equipped with drip ring,
And drip ring is in inverted L-shaped, the dustproof lip and drip ring are in 30 degree to 35 degree angles, the dustproof lip, main lip and grease proofing
Lip is contacted with drip ring respectively.
Preferably, it is equipped with the first fixing groove between rubber pad and cyclic annular fixed skeleton top, and bottom is fixed equipped with second
Slot, the rubber pad are fixedly connected in fixed skeleton by the first fixing groove and the second fixing groove with cyclic annular.
Preferably, the drip ring bottom side chamfering.
Compared with prior art, the utility model has the beneficial effects that
1, drip ring is inserted into bearing by the way that cyclic annular fixed skeleton to be mounted on the inside of the Internal and external cycle of bearing by the utility model
On the outside of inner ring, the chamfering of drip ring bottom, convenient in water blocking insertion bearing, when automobile tire rotates, main lip is contacted with drip ring,
Thickness between main lip and rubber pad is lower, increases the elasticity of radial main lip, and the enclasping force of the axis appropriate reduced is dust-proof
Angle between lip and rubber pad is larger, reduces the frictional force of dustproof lip and drip ring, sealing ring is made to be chronically at low torque
It works under state, plays the effect of energy-saving and emission-reduction.
Detailed description of the invention
Fig. 1 is the utility model schematic cross-sectional view.
In figure: the fixed skeleton of 1- ring-type；2- rubber pad；3- dustproof lip；The main lip of 4-；The grease proofing lip of 5-；6- drip ring；7-
One fixing groove；The second fixing groove of 8-.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: low torque automotive hub bearing sealing ring, including ring
Shape fixes skeleton 1, rubber pad 2, dustproof lip 3, main lip 4, grease proofing lip 5 and drip ring 6, and the cyclic annular fixed skeleton 1 is located at bearing
On the inside of outer ring, and cyclic annular fixed 1 section of skeleton is L shape, is fixed with rubber pad 2, institute on the inside of the cyclic annular fixed skeleton 1L shape
2 top dustproof lip 3 of rubber pad is stated, 2 side of rubber pad is equipped with main lip 4, and bottom is equipped with grease proofing lip 5, the rubber pad 2 one
Side is equipped with drip ring 6, and drip ring 6 is in inverted L-shaped, and the dustproof lip 3 is in 30 degree to 35 degree angles with drip ring 6, described
