Description
Technical field
It the utility model is related to a kind of bearing dust-proof sealing structure, and in particular to one kind is used for heavy duty truck, engineering truck
And the dust-proof sealing structure of the Self-regulation core-tension type clutch release bearing on city bus.
Background technology
The sealing structure of existing Self-aligning pulling automobile clutch release bearing uses the rubber seal with skeleton, peace
In bearing outer ring seal groove, and make the inner lip of sealing ring and inner ring is cylindrical contacts.Because seal lip with inner ring is cylindrical connects
Touch coordinates, and bearing is larger in starting torque caused by rotation.Bearing inner ring after operating causes with sealing ring constantly friction
The lip abrasion of sealing ring, after abrasion to a certain extent, internal diameter of the seal ring lip and inner ring contact position occur gap, grease from
Flowed out at sealing, bearing lacks meeting premature failure after lubrication, influences service life.
The content of the invention
In place of the purpose of this utility model is to overcome above-mentioned deficiency, effectively it can prevent external dust from entering so as to provide one kind
Enter, reduce bearing starting torque, good sealing effect, bearing seal structure simple in construction.
According to the technical solution of the utility model, the bearing dust-proof sealing structure, including inner ring, retainer, outer cover, steel
Ball, outer ring, wavy spring and release sleeve, in addition to interior dust cap and outer dust cap, the interior dust cap are arranged on outside inner ring
On round platform rank, the outer dust cap is arranged on inner surface, the centre position of inner surface and the inner ring outer surface
The mutual corresponding groove of circumferencial direction is respectively equipped with, the steel ball is positioned at the groove of outer ring and inner ring using retainer
Interior, the wavy spring is arranged on the gap between outer ring and release sleeve, and the outer cover rolls bearing and release sleeve
Together.
Further, radial direction of the left end of the outer cover along outer cover bends to center and extended, and forms covering portion, the cladding
Portion is coated on outside the left end of outer ring；The right-hand member of the release sleeve extends radially outwardly along release sleeve, forms flange end,
Also extending radially outwardly along release sleeve, formation installation portion, the right-hand member of outer cover are covered in installation portion at the middle part of release sleeve
Circumferential exterior surface, and formed in the right-hand member of outer cover and the overlay area of installation portion and roll groove.
Further, the interior dust cap and outer dust cap are shaped as concaveconvex structure, and in interior dust cap and outer dust cap
Between formed a tortuous loop.
Further, the interior dust cap and outer dust cap are not in contact with each other.
Compared with prior art, the utility model has advantages below：It is simple, compact and reasonable for structure；Interior dust cap with it is outer
Dust cap is not in contact with each other, and during bearing rotary, is not interfere with each other, and can effectively reduce frictional force when bearing rotates；Interior dust cap with
It is dust-proof outside to be shaped as concaveconvex structure, and a tortuous loop is formed, the entrance of external dust and the leakage of lubricating grease are avoided that, is risen
To the effect of dust seal.

Embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2：Bearing dust-proof sealing structure, including inner ring 1, interior dust cap 2, outer dust cap 3, retainer 4,
Outer cover 5, steel ball 6, outer ring 7, wavy spring 8 and release sleeve 9.Interior dust cap 2 is arranged on 1 cylindrical step of inner ring, outer dust-proof
Lid 3 is arranged on the inner surface of outer ring 7.The centre position of the inner surface of outer ring 7 and the outer surface of inner ring 1 is respectively equipped with circumferencial direction
It is mutual corresponding to groove, steel ball 6 is positioned at using retainer 4 in the groove of outer ring 7 and inner ring 1.Wavy spring 8 is installed
Gap between outer ring 7 and release sleeve 9, installing space very little, and noise can be effectively reduced, reduce vibration.Outer cover 5
Together with bearing is rolled with release sleeve 9, the main part of bearing is formed, specifically, footpath of the left end of outer cover 5 along outer cover 5
Extend to being bent to center, form covering portion 13, covering portion 13 is coated on outside the left end of outer ring 7；The right-hand member edge of release sleeve 9
Release sleeve 9 extends radially outwardly, and forms flange end 12, the middle part of release sleeve 9 also radially outward prolonging along release sleeve 9
To stretch, form installation portion 11, the right-hand member of outer cover 5 is covered in the circumferential exterior surface of installation portion 11, and in the right-hand member and installation portion of outer cover 5
11 overlay area forms and rolls groove 10.
Specifically, interior dust cap 2 and outer dust cap 3 are shaped as concaveconvex structure, and form a tortuous loop.It is avoided that outer
The entrance of portion's dust and the leakage of lubricating grease, play the effect of dust seal.Interior dust cap 2 and outer dust cap 3 are not in contact with each other,
During bearing rotary, it does not interfere with each other, frictional force when bearing rotates can be effectively reduced.
The utility model is simple in construction, and bearing starting torque is small, good sealing effect, dust-proof by dust-proof in being not in contact with each other
Lid and the realization of outer dust cap, good dustproof effect, and reduce frictional force when bearing rotates, sealed in the prior art so as to avoid
The lip abrasion of circle, grease flow out at sealing, and bearing lacks the problem of premature failure after lubrication, and improving release bearing makes
Use the life-span.
