Description
Technical field
The utility model belongs to technical field of bearings, especially relevant with a kind of black box being applicable to bearing.
Background technique
Bearing is provided with black box usually, existing black box generally comprises sealing cover, skeleton and seal ring, sealing cover and skeleton are fixedly connected with inner ring with bearing outer ring respectively and are oppositely arranged, seal ring is fixedly connected with skeleton, seal ring be provided with sealing cover against an axial lip and two footpath labiads, wherein two footpath labiads are herringbone structure, bearing is in assembly process, first the skeleton be fixedly connected with and seal ring are first fixed on bearing inner race often, then sealing cover is press-fited and on the inner headed face of bearing outer ring, the axial lip on seal ring and footpath labiad are all resisted against on sealing cover, it is contrary that one of them footpath labiad and sealing cover due to herringbone structure press-fit direction, add that footpath labiad and sealing cover abutment facing exist magnitude of interference, after causing assembling, this footpath labiad easily turns over lip, seal ring moment of torsion is caused to become large, easy heating, rubber easily weares and teares, the working life of seal ring shortens, and then shorten the life-span of bearing.
Model utility content
The purpose of this utility model be intended to overcome existing seal ring in assembly process wherein a footpath labiad easily turn over the defect that lip makes the working life of shortening seal ring, provide a kind of good sealing effect and the black box being applicable to bearing of seal ring long service life.
For this reason, the utility model is by the following technical solutions: a kind of black box being applicable to bearing, comprise seal ring, metal frame and sealing cover, it is characterized in that, described metal frame comprises retainer ring and from the outward extending annular support part of the outer circumferential face of this retainer ring one end, the radial cross-section of metal frame is made to be L shape, inner peripheral surface and the bearing inner race outer circumferential face of retainer ring are fixed, described annular support part is provided with a kink and makes annular support part forming station terrace, described sealing cover comprises integrated cylindrical portion and annular sealing portion, its radial cross-section is made to be L shape, the outer circumferential face of cylindrical portion is fixedly connected with the inner headed face of bearing outer ring and corresponding with described retainer ring position, described annular sealing portion is overhanging shape and corresponding with described annular support part, described seal ring comprises base portion, a parcel lip, a footpath labiad and two axial lips, the shape of base portion is fitted with the inner surface of described metal frame and is fixedly connected with, parcel lip, footpath labiad and two axial lips are set in turn on described base portion, parcel lip is coated on described step surface, add the degree of being connected firmly of seal ring and metal frame, footpath labiad interference is resisted against described cylindrical portion, it is consistent that true dip direction and the sealing cover of footpath labiad press-fit direction, avoid press-fiting the phenomenon producing in process and turn over lip, prevent grease from leaking outside simultaneously, two described axial lips are all resisted against described annular sealing portion, the true dip direction of two axial lips is all towards the overhanging direction of annular sealing portion, effectively prevent dust, muddy water etc. enter Bearing inner, add effectiveness.
The utility model can reach following beneficial effect: cancel with the footpath labiad that sealing cover press-fits direction contrary, increase an axial lip simultaneously, avoid sealing cover and press-fit in process the problem making footpath labiad generation turn over lip, improve efficiency of assembling, extend the working life of seal ring, and the interference two of the annular sealing portion of axial lip and sealing cover can be adjusted by press mounting die, convenient control.
