As shown in figure 3, it is more firm in order to block the rotating wheel to fall off 121, it can be at the bottom of the installation groove 121b
Portion and place setting rubber layer 122 close to bottom sides, since the frictional force of rubber layer 122 is bigger, and have elasticity can be with
By the stuck bottom in installation groove 121b of the rotating wheel 121 to fall off.And when the anti-jamming bearing generates in use
The rotating wheel 121 for falling off or damaging in rotating wheel 121 panelling to rubber layer 122 to fall off, can will be prevented stifled when vibration
Slideway is filled in, stuck bearing influences normal rotation of bearing when not placing under repair.
Preferably, one of side of the bearing inner race 120 is provided with multiple through-holes, such as is not installing fixed block
124 side.Each through-hole corresponds to an installation groove 121b, and the through-hole is connected to the installation groove 121b
With the outer surface of the bearing inner race 120, the stuck loosening of rotating wheel 121 can be will fall off by the through-hole and cleaned up, just
In replacement.
When needing to illustrate, rubber layer can be set in the region in one, ground, 121 diameter range of rotating wheel
122, material can be saved in this way.In addition, the shape of the rotating wheel 121 can be cylinder, and in the rotating wheel 121
The edges and corners of two end side surfaces be set as rounded structure, the rotating wheel 121 and first outer ring 111 and second outer ring
The complete slideway formed after 112 connections matches.Axle bearing mount portion can also be arranged in the anti-jamming bearing arrangement 100, pass through
Axle bearing mount portion can apply the anti-jamming bearing arrangement 100 on wheel or other rotating devices.
A kind of anti-jamming bearing arrangement 100 provided in an embodiment of the present invention, comprising: the first outer ring 111, the second outer ring 112,
Bearing inner race 120；First outer ring 111 and second outer ring 112 are circumferentially positioned at the separate circle of the bearing inner race 120
The outside of the heart；First outer ring 111 is fixedly connected with second outer ring 112 by screw 113；Pair that can be convenient in this way
First outer ring 111 and second outer ring 112 are dismantled or are replaced.The marginal portion of the bearing inner race 120 is arranged
There are multiple installation groove 121b；Installation axle 121a, each installation axle are provided in each installation groove 121b
It is provided with rotating wheel 121 on 121a, by the rotation of the rotating wheel 121, the bearing inner race 120 can be made described
It is rotated inside one outer ring 111 and second outer ring 112.The bottom of each installation groove 121b is in a rectangle, and
And the installation groove 121b bottom width is less than the diameter of the rotating wheel 121, which can be in the installation axle 121a
Fracture, remove or when rotating wheel 121 falls off, by the rotating wheel 121 installation groove 121b bottom clamping.Often
The bottom and side of a installation groove 121b is provided with rubber layer 122；The rubber layer 122 can make the rotation to fall off
Take turns the stronger of 121 clampings.The side for being provided with rubber layer 122 is apart from the rotating wheel 121 of the bottom surface one
Side in diameter range can achieve the rotating wheel 121 that will be fallen off in this way and be stuck in bottom, and saves material.The present invention is real
A kind of anti-jamming bearing arrangement 100 for applying example offer is stuck in the installation groove 121b by the rotating wheel 121 that damage falls off
Bottom, do not place under repair replacement in the case where continue to use, bearing prevented to be stuck the case where.And bearing can be with
It repairs and uses repeatedly.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
