Abstract
The utility model relates to the technical field of bearings, in particular to a bearing provided with two rows of cylindrical rollers. The bearing comprises mounting sleeves, inner rings, two rows of the cylindrical rollers and a retainer, wherein the two rows of the cylindrical rollers are mounted between concave roller paths on the outer surfaces of the inner rings and concave roller paths on the inner surfaces of the mounting sleeves through the retainer; clamping springs are arranged between the two rows of the cylindrical rollers; and space rings are arranged on two sides of each clamping spring respectively. According to the bearing provided with the double rows of the cylindrical rollers, retainer rings are arranged between the two rows of the cylindrical rollers, so that friction can be effectively reduced, the structure is compact, the mounting is convenient, the operation is flexible, the rigidity is high, the bearing capacity is large, deformation after loading is small, and the service life is long.
Description
Technical field
The utility model relates to technical field of bearings, especially a kind of Biserial cylindrical roller bearing.
Background technique
In industries such as automobile, milling train, mine, metallurgy, plastics machineries, can require to have supporting design bearing, often can use roller bearing, during common Biserial cylindrical roller bearing High Rotation Speed, between two line column rollers, very large friction can be produced, the high-revolving requirement of high load cannot be tackled; Sometimes one end, the outer footpath of roller is different with one end, inner footpath rotating speed, and the large and rolling element of wearing and tearing easily skids off, and has a strong impact on working life.
Model utility content
The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned existence, provide a kind of Biserial cylindrical roller bearing.
The utility model solves the technological scheme that its technical problem adopts: a kind of Biserial cylindrical roller bearing, comprise installation sleeve, inner ring, two line column rollers and retainer, two described line column rollers are contained between the recessed raceway and the recessed raceway on installation sleeve internal surface on inner ring outer surface by retainer, in the middle of two described line column rollers, be provided with jump ring, described jump ring both sides are provided with a spacer ring separately.
Further, described jump ring is circlip for hole.
Further, the radian of described inner ring one side external surface is greater than the radian of opposite side outer surface.
The beneficial effects of the utility model are that Biserial cylindrical roller bearing of the present utility model arranges back-up ring between two cylindrical rollers, can effectively reduce friction, compact structure, easy for installation, flexible operation, rigidity is strong, bearing capacity is large, be subject to be out of shape after load little, long service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. installation sleeves in figure, 2. inner ring, 3. cylindrical roller, 4. spacer ring, 5. jump ring.
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 is only described in a schematic way, so it only show the formation relevant with the utility model.
Biserial cylindrical roller bearing as shown in Figure 1, comprise installation sleeve 1, inner ring 2, two line column roller 3 and retainers, two line column rollers 3 are contained between the recessed raceway and the recessed raceway on installation sleeve 1 internal surface on inner ring 2 outer surfaces by retainer, in the middle of two line column rollers 3, be provided with jump ring 5, jump ring 5 both sides are provided with a spacer ring 4 separately.Jump ring 5 is circlip for hole.The radian of inner ring 2 one side external surfaces is greater than the radian of opposite side outer surface.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this model utility technological thought, carry out various change and modification completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
