The ball being filled between the interior rollaway nest face of inner ring and the outer rollaway nest face of outer ring.
The inside edge far from interior rollaway nest is provided with inner ring chamfering on inner ring, and the outer ledge far from outer rollaway nest is set on outer ring It is equipped with outer ring chamfering.
Preferably, interior rollaway nest face altogether there are two, outer rollaway nest face altogether there are two, be provided between two roller surfaces lubricant storage Deposit slot.
There is gasket in the side of ball bearing, there is on inner ring side the first seal groove, the first seal groove on inner ring The wall height of both sides differs, and wherein the difference in height between the relatively low side of inner ring side wall and inner ring chamfering is L, and L is equal to sealing advance capital for The thickness of body;Difference in height on outer ring in the second seal groove between the relatively low side of side wall and inner ring chamfering is, and L1 is more than L.
Gasket is circular ring shape, is arranged between the first seal groove and the second seal groove.
There are one bending parts for the ontology tool of gasket, are arranged at the inner ring of annular seal pad, wherein bending part is set Among the first seal groove, the labyrinth sealing end of gasket is set among the second seal groove.
The labyrinth sealing end is arranged by the parts space of multiple annular dentations, and corresponding second seal groove has Multiple annular tooth-like recesses.
Contact seal piece is provided on the bending part of gasket, the first seal sticking is in the groove-bottom of the first seal groove Portion.
Preferred contact seal piece is preferably made of synthetic rubber such as nitrile rubber, acrylic rubber, silicon rubber.
Synthetic rubber is suitable for being bonded under sulfided state the inner ring and outer ring of the ontology level-one ball bearing of gasket 3 On.
It is further preferred that the first seal sticking is in the recess sidewall of the first seal groove.
Compared with prior art, the utility model is sealed ball bearing using gasket, labyrinth sealing end tool There is the performance that is bonded and sealed more better than gasket seal, and reliability is high, works for a long time in various adverse circumstances suitable for bearing.
The direct drinking fountain bearing outer ring edge plagioclase shape for the frequent starting in the prior art that the utility model avoids adds Work defect directly with the chamfer shape processing program of grinding, simplifies manufacturing procedure, changes original long angle of internal friction and outer ring is pasted Occupying for area is closed, compared to the contact area increase between outer ring and bearing mounting bracket, adhesive force increase, it is not easy to loosen And slippage.
The single-contact of original conventional ball and Internal and external cycle raceway inner wall is changed to two point contact by the utility model, practical Contact point have original Internal and external cycle 2 be changed to totally 4 contact points, improve the resistivity of axial displacement.
