The defects of holding, often being not easy to take out from bearing there are sealing element.This also result in Bearing inner addition lubricant inconvenience
The problem of, and if detachable structure is set on the outside of sealing ring, can in bearing working by sealing ring to outside produce shadow
Ring, it is therefore necessary to be improved.
The content of the invention
The purpose of the present invention is for the above-mentioned problems in the prior art, there is provided and it is a kind of compact-sized, and conveniently
Seal member is opened, and adds the detachable deep groove ball bearing sealing structure of lubricant.
The purpose of the present invention can be realized by following technical proposal：A kind of detachable deep groove ball bearing sealing structure, bag
Include bearing inner race, bearing outer ring, retainer and steel ball, it is characterised in that：Bearing inner race outer surface is respectively equipped with steel ball both sides
Annular seal groove one, bearing outer ring inner surface are respectively equipped with annular seal groove two in steel ball both sides, further include ring type seal, institute
On the sealing ring stated respectively have with seal groove one and the matched ring packing wing of seal groove two, and the sealing wing difference it is embedding
In seal groove one and seal groove two, and sealing ring outer end face is smooth with bearing inner race outer end face and bearing outer ring outer end face respectively
Transition, is equipped with Thin ring plate shape reinforcing plate in the sealing ring, and reinforcing plate and bearing inner race are coaxial, reinforcement plate surface and
Bearing inner race axis is vertical, some rod-shaped pull rods in sealing ring is fixed with the reinforcing plate, and tie rod end has
There is internal thread groove or be bent to form hook, the sealing ring outer end face has some counterbores, and tie rod end is located in counterbore.
Coordinated using the sealing wing and the seal groove one and seal groove two of sealing ring and play sealing function, can also will be with outer spiral shell
The provision for disengagement of line and the internal thread groove of tie rod end are spirally connected, or the extension for making the provision for disengagement with hook hook tie rod end
Hook, and sealing ring is pulled outwardly, sealing ring is separated with bearing, lubricant can be added towards inside afterwards, and due to sealing
Circle outer end face is seamlessly transitted with bearing inner race outer end face and bearing outer ring outer end face respectively, therefore sealing ring will not be in bearing working
When outside is had an impact, and reinforcing plate plays reinforcement effect, makes sealing ring integral demounting, avoids sealing ring from being drawn bad.
In a kind of above-mentioned detachable deep groove ball bearing sealing structure, the pull rod is circumferentially distributed along sealing ring, and
Pull rod is parallel with bearing inner race axis.
Therefore more convenient dismounting sealing ring.
In a kind of above-mentioned detachable deep groove ball bearing sealing structure, the pull rod and reinforcing plate are to be welded and fixed.
In a kind of above-mentioned detachable deep groove ball bearing sealing structure, the sealing ring outer end face is respectively towards in bearing
Circle and bearing outer ring extension are equipped with annular block wing, and block wing reclines bearing inner race outer end face respectively and bearing outer ring outer end face is set
Put.
Therefore sealing effect is more preferable.
Compared with prior art, the invention has the advantages that：
Coordinated using the sealing wing and the seal groove one and seal groove two of sealing ring and play sealing function, can also will be with outer spiral shell
The provision for disengagement of line and the internal thread groove of tie rod end are spirally connected, or the extension for making the provision for disengagement with hook hook tie rod end
Hook, and sealing ring is pulled outwardly, sealing ring is separated with bearing, lubricant can be added towards inside afterwards, and due to sealing
Circle outer end face is seamlessly transitted with bearing inner race outer end face and bearing outer ring outer end face respectively, therefore sealing ring will not be in bearing working
When outside is had an impact, and reinforcing plate plays reinforcement effect, makes sealing ring integral demounting, avoids sealing ring from being drawn bad.

Embodiment
It is the specific embodiment of the present invention and with reference to attached drawing below, technical scheme is further described,
But the present invention is not limited to these embodiments.
As shown in Figs 1-4, a kind of detachable deep groove ball bearing sealing structure of the present invention, including bearing inner race 1, bearing outer ring
2nd, retainer 3 and steel ball 31,1 outer surface of bearing inner race are respectively equipped with annular seal groove 1, bearing outer ring 2 in 31 both sides of steel ball
Inner surface is respectively equipped with annular seal groove 2 21 in 31 both sides of steel ball, further includes ring type seal 4, has respectively on sealing ring 4
With seal groove 1 and the matched ring packing wing 41 of seal groove 2 21, and seal the wing 41 respectively embedded in seal groove 1 and sealing
In groove 2 21, and 4 outer end face of sealing ring is seamlessly transitted with 1 outer end face of bearing inner race and 2 outer end face of bearing outer ring respectively, sealing ring
