The purpose of this utility model can be realized by following technical proposal: a kind of deep-groove ball
Bearing seal structure, including bearing inner race, bearing outer ring, retainer and steel ball, it is special
Levy and be: bearing inner race outer surface is respectively provided on two sides with annular seal groove one, axle at steel ball
Bearing outer-ring inner surface is respectively provided on two sides with annular seal groove two at steel ball, also includes that annular is close
Seal, described sealing ring is respectively provided with the ring mated with seal groove one and seal groove two
Shape seals the wing, and the described sealing wing is embedded in seal groove one and seal groove two respectively, and
Sealing ring outer face is smoothed with bearing inner race outer face and bearing outer ring outer face respectively
Cross, described sealing ring be additionally provided with overall curved and that cross section is rounded poroid pulling eye,
And pulling eye two ends lay respectively at sealing ring outer face, it is provided with arc in described pulling eye hollow
Metallic sheath, and the attaching pulling eye hole wall setting of metallic sheath outer wall.
The sealing wing utilizing sealing ring coordinates with seal groove one and seal groove two to play to seal to be made
With, it is also possible to metallic cable or tightrope are penetrated metallic sheath, and pulls sealing ring outwardly, make
Sealing ring separates with bearing, can add lubricant afterwards towards inside, and owing to sealing
Circle outer face seamlessly transits with bearing inner race outer face and bearing outer ring outer face respectively, because of
This sealing ring will not produce impact when bearing working to outside.
In above-mentioned a kind of deep groove ball bearing seals structure, described pulling eye is along sealing ring
Circumferentially distributed, and the plane at pulling eye place is radial parallel with sealing ring.
The most convenient dismounting sealing ring.
In above-mentioned a kind of deep groove ball bearing seals structure, described pulling eye two ends are respectively
Arrange near bearing inner race outer surface and bearing outer ring inner surface.
In above-mentioned a kind of deep groove ball bearing seals structure, described sealing ring outer face
Extend towards bearing inner race and bearing outer ring respectively and be provided with annular block wing, and block wing reclines respectively
Bearing inner race outer face and bearing outer ring outer face are arranged.
Therefore sealing effectiveness is more preferable.
Compared with prior art, this utility model has the advantage that
The sealing wing utilizing sealing ring coordinates with seal groove one and seal groove two to play to seal to be made
With, it is also possible to metallic cable or tightrope are penetrated metallic sheath, and pulls sealing ring outwardly, make
Sealing ring separates with bearing, can add lubricant afterwards towards inside, and owing to sealing
Circle outer face seamlessly transits with bearing inner race outer face and bearing outer ring outer face respectively, because of
This sealing ring will not produce impact when bearing working to outside.
