Abstract
The utility model discloses a deep groove ball bearing which is less prone to axial size limitation and capable of bearing great load, in particular to a double-layer deep groove ball bearing. The double-layer deep groove ball bearing comprises an outer ring, wherein a first inner ring is arranged in an inner hole of the outer ring, a second inner ring is arranged in the inner hole of the first inner ring, a first rolling ball group is arranged between the outer ring and the first inner ring, a second rolling ball group is arranged between the first inner ring and the second inner ring, and the radius of steel balls in the first rolling ball group is larger than that of the steel balls in the second rolling ball group. The double-layer deep groove ball bearing disclosed by the utility model adopts the double-layer design and can significantly improve the bearing load of the bearing when the axial size is fixed, and the double-layer deep groove ball bearing adopting the scheme has the advantages of compact and simple structure, convenience in manufacturing and processing and good using effects.
Description
Technical field
The utility model relates to technical field of bearings, especially a kind of double-deck deep groove ball bearing.
Background technique
In known technical field, deep groove ball bearing is one type the most common in the rolling bearing, the deep groove ball bearing of basic model has an outer ring, an inner ring and one group of steel ball, deep groove ball bearing mainly bears radial load, also can bear simultaneously radial load and thrust load, when it only bears radial load, wrapping angle is zero, when deep groove ball bearing has larger radial internal clearance, have the performance of angular contact bearing, can bear larger thrust load, the friction factor of deep groove ball bearing is very little, and limit speed is also very high.
In the installing and using of existing deep groove ball bearing, in bulk one regularly, if increase the carrying of bearing, can be at the bearing that axially increases again a same model, perhaps change the bearing of larger model, but above-mentioned two kinds of methods have certain narrow limitation when axial space is less, can not comparatively be convenient to use.
The model utility content
The technical problems to be solved in the utility model is: a kind of axial dimension restriction and large deep groove ball bearing of bearing load of not being subject to is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of double-deck deep groove ball bearing, comprise the outer ring, in the endoporus of described outer ring, be provided with the first inner ring, in the endoporus of described the first inner ring, be provided with the second inner ring, between described outer ring and the first inner ring, be provided with the first ball set, be provided with the second ball set between the first inner ring and the second inner ring.
Further, as a kind of concrete form, the radius of the steel ball in the first ball set described in the utility model is greater than the radius of the steel ball in the second ball set.
Further, as a kind of concrete form, the radius of the steel ball in the first ball set described in the utility model equals the radius of the steel ball in the second ball set.
The beneficial effects of the utility model: the utility model adopts the design of double layer, so that regularly can significantly improve the bearing load of bearing at axial dimension one, this programme compact structure is simple, makes easy to processly, and using effect is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1. outer ring, 2-1. the first inner ring, 2-2. the second inner ring, 3-1. the first ball set, 3-2. the second ball set.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of double-deck deep groove ball bearing of the utility model as shown in Figure 1, comprise outer ring 1, in the endoporus of described outer ring 1, be provided with the first inner ring 2-1, in the endoporus of described the first inner ring 2-1, be provided with the second inner ring 2-2, between described outer ring 1 and the first inner ring 2-1, be provided with the first ball set 3-1, be provided with the second ball set 3-2 between the first inner ring 2-1 and the second inner ring 2-2, and the radius of the steel ball among described the first ball set 3-1 is greater than the radius of the steel ball among the second ball set 3-2.
The radius of the steel ball among the first ball set 3-1 described in above-described embodiment can also equal the radius of the steel ball among the second ball set 3-2.
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 the specification, must determine its technical scope according to the claim scope.
