Abstract
A bearing comprises a bearing outer ring, a bearing inner ring and rolling bodies. A bearing middle ring is arranged between the bearing outer ring and the bearing inner ring. Space between the bearing outer ring and the bearing middle ring and between the bearing middle ring and the bearing inner ring are respectively provided with rolling bodies. The bearing has the advantages that a layer of rolling bodies are additionally arranged on a circle of rolling bodies so that friction resistance borne by the bearing when an object is loaded is further reduced and service life of the bearing is greatly improved.
Description
Technical field
The utility model relates to a kind of bearing.
Background technique
Bearing has very widely to be used, be mainly used in supporting rotator, and reduce friction factor, yet some bearing cause because load capacity is less, easy to wear.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of bearing is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of bearing, comprise bearing outer ring, bearing inner race and rolling element, in the middle of described bearing outer ring and bearing inner race, a bearing centre circle is arranged, be provided with rolling element between described bearing outer ring and bearing centre circle and bearing centre circle and bearing inner race.
The beneficial effects of the utility model are: a kind of bearing is provided, adds one deck roller again on a circle roller, the surface friction drag that is subject to when making the bearing loading further reduces, and has greatly improved the working life of bearing.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation of bearing;
Wherein: 1, bearing outer ring, 2, the bearing centre circle, 3, bearing inner race, 4, rolling element.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of bearing as shown in Figure 1, comprise bearing outer ring 1, bearing inner race 3 and rolling element 4, in the middle of described bearing outer ring 1 and bearing inner race 3, a bearing centre circle 2 is arranged, 3 of described bearing outer ring 1 and bearing centre circle 2 and bearing centre circle 2 and bearing inner races are provided with rolling element 4, setting by double-deck roller has greatly reduced the suffered frictional force of bearing, the working life of having improved bearing.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to the claim scope.
Claims (1)
1. bearing, comprise bearing outer ring (1), bearing inner race (3) and rolling element (4), it is characterized in that: in the middle of described bearing outer ring (1) and bearing inner race (3), a bearing centre circle (2) is arranged, be provided with rolling element (4) between described bearing outer ring (1) and bearing centre circle (2) and bearing centre circle (2) and bearing inner race (3).
