Abstract
The invention discloses a bearing capable of compensating wear loss automatically. The bearing comprises a bearing outer ring and a bearing inner ring rotationally matched with the bearing outer ring, wherein a plurality of arc elastic pieces extending in the circumferential direction are parallelly arranged in the circumferential direction of the outer circumferential surface of the baring inner ring, and end parts of the arc elastic pieces are warped outwards in the radial direction and contacted with the inner surface of the bearing outer ring. According to the bearing capable of compensating the wear loss automatically, the arc elastic pieces are arranged on the bearing inner ring, when a gap between the bearing inner ring and the bearing outer ring is enlarged due to wear of a matching surface of the bearing inner ring and the bearing outer ring, the end parts of the arc elastic pieces can still be attached to the inner surface of the bearing outer ring automatically under the action of elastic force, so that the wear loss of the matching surface is compensated automatically, the influence of the matching surface wear on the bearing precision is reduced, and the service life of the bearing can be prolonged greatly.
Description
Technical field
The present invention relates to a kind of bearing, particularly a kind of bearing of energy auto-compensation wear extent.
Background technique
The main structure of bearing of the prior art comprises an inner ring and an outer ring, inner ring is coordinated with outer ring by the structure such as ball or sphere, but bearing of the prior art, when after its long-play, the fitting surfaces such as inner ring, outer ring and ball can wear and tear, wearing and tearing can cause the precision of bearing to reduce, and abnormal sound increases, thus causes bearing fault; But prior art middle (center) bearing does not have the matching gap structure automatically made up because wearing and tearing increase, and makes the life-span of bearing shorter.
Summary of the invention
In view of this, the object of this invention is to provide a kind of can the bearing of auto-compensation wear extent, can not auto-compensation fitting surface wear extent to solve bearing of the prior art, cause the technical problem that bearing life is shorter.
The bearing of energy auto-compensation wear extent of the present invention, the bearing inner race comprising bearing outer ring and be rotatably assorted with bearing outer ring, the periphery of described bearing inner race is along the circumferential direction set side by side with some arc spring laminations along the circumferential direction extended, the end of described arc spring lamination radially tilts and contacts with the internal surface of bearing outer ring.
Further, described bearing outer ring and bearing inner race are made up of plastic materials, the inner hole surface of described bearing inner race are provided with the double wedge for increasing frictional force between itself and axle.
Further, the fitting surface of described bearing outer ring and bearing inner race is sphere.
Beneficial effect of the present invention:
The bearing of energy auto-compensation wear extent of the present invention, it by arranging arc spring lamination on bearing inner race, when the fitting surface wearing and tearing of bearing inner race and bearing outer ring cause the gap between bearing inner race and bearing outer ring to increase, the end of arc spring lamination under elastic force effect still can automatically and the internal surface of bearing outer ring fit, thus the wear extent of auto-compensation fitting surface, reduce the impact of fitting surface wearing and tearing on bearing accuracy, the working life of prolongation bearing that can be very large.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the bearing of the present embodiment energy auto-compensation wear extent;
Fig. 2 is the perspective view of bearing inner race.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the bearing of the present embodiment energy auto-compensation wear extent, the bearing inner race 2 comprising bearing outer ring 1 and be rotatably assorted with bearing outer ring, the periphery of described bearing inner race is along the circumferential direction set side by side with some arc spring laminations 3 along the circumferential direction extended, the end of described arc spring lamination radially tilts and contacts with the internal surface of bearing outer ring.
The bearing of the present embodiment energy auto-compensation wear extent, it by arranging arc spring lamination on bearing inner race, when the fitting surface wearing and tearing of bearing inner race and bearing outer ring cause the gap between bearing inner race and bearing outer ring to increase, the end of arc spring lamination under elastic force effect still can automatically and the internal surface of bearing outer ring fit, thus the wear extent of auto-compensation fitting surface, reduce the impact of fitting surface wearing and tearing on bearing accuracy, the working life of prolongation bearing that can be very large.
In the present embodiment, described bearing outer ring and bearing inner race are made up of plastic materials, the inner hole surface of described bearing inner race is provided with the double wedge 4 for increasing frictional force between itself and axle, when axle is assembled on bearing inner race, the stressed generation resiliently deformable of double wedge thus to bearing apply pressure, the combination force between bearing inner race and axle can be increased, axle is assembled more reliable.
In the present embodiment, the fitting surface of described bearing outer ring 1 and bearing inner race 2 is sphere, and this improvement makes arc spring lamination 3 can transport in on joint shaft bearing, and operation strategies is wide.
What finally illustrate is, above embodiment is only in order to illustrate technological scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technological scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
