Bearing outer ring inner surface is respectively provided on two sides with annular seal groove two at steel ball, also includes annular
Sealing ring, described sealing ring is respectively provided with and mates with seal groove one and seal groove two
The ring packing 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, in described sealing ring, be provided with Thin ring plate shape reinforcing plate, and reinforcing plate and bearing
Inner ring is coaxial, and reinforcing plate surface is vertical with bearing inner race axis, solid in described reinforcing plate
Surely have some shaft-like pull bars being positioned at sealing ring, and tie rod end have female thread groove or
Being bent to form hook, described sealing ring outer face has some counterbores, and tie rod end
It is positioned at counterbore.
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 will be spirally connected with the female thread groove of externally threaded provision for disengagement with tie rod end,
Or the hook of tie rod end is hooked in the provision for disengagement making band hook, and pulls sealing outwardly
Circle, makes sealing ring separate with bearing, can add lubricant, Er Qieyou afterwards towards inside
Smoothed with bearing inner race outer face and bearing outer ring outer face respectively in sealing ring outer face
Crossing, therefore outside will not be produced by sealing ring when bearing working affects, and reinforcing plate
Play reinforcement effect, make sealing ring integral demounting, it is to avoid sealing ring is drawn bad.
Seal in structure at above-mentioned a kind of detachable deep groove ball bearing, described pull bar edge
Sealing ring is circumferentially distributed, and pull bar is parallel with bearing inner race axis.
The most convenient dismounting sealing ring.
Seal in structure at above-mentioned a kind of detachable deep groove ball bearing, described pull bar and
Reinforcing plate is for being welded and fixed.
Seal in structure at above-mentioned a kind of detachable deep groove ball bearing, described sealing ring
Outer face is provided with annular block wing towards bearing inner race and bearing outer ring extension respectively, and block wing divides
Do not recline bearing inner race outer face and the setting of bearing outer ring outer face.
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 will be spirally connected with the female thread groove of externally threaded provision for disengagement with tie rod end,
Or the hook of tie rod end is hooked in the provision for disengagement making band hook, and pulls sealing outwardly
Circle, makes sealing ring separate with bearing, can add lubricant, Er Qieyou afterwards towards inside
Smoothed with bearing inner race outer face and bearing outer ring outer face respectively in sealing ring outer face
Crossing, therefore outside will not be produced by sealing ring when bearing working affects, and reinforcing plate
Play reinforcement effect, make sealing ring integral demounting, it is to avoid sealing ring is drawn bad.
