Abstract
The utility model relates to the technical field of cylindrical roller bearings and particularly relates to a lubrication type double-row cylindrical roller bearing comprising an outer bearing ring, an inner bearing ring, two columns of cylindrical rollers and a retainer, wherein the outer bearing ring and the inner bearing ring are respectively arranged at the inner side and the outer side of a columnar body formed by the cylindrical rollers and the retainer; the center of the outer bearing ring is provided with an oil injection hole. The lubrication type double-row cylindrical roller bearing disclosed by the utility model is high in bearing capacity, high in load capacity, good in lubricating effect, small in friction, suitable for rotating at high speed, flexible in operation, high in rigidity and long in service life.
Description
Technical field
The utility model relates to the roller bearing technical field, especially a kind of lubricating type Biserial cylindrical roller bearing.
Background technique
In industries such as automobile, milling train, mine, metallurgy, plastics machineries; can require has supporting design bearing, often can use tapered roller bearing, and mainly bearing radially is main footpath, axial connected load; bearing load carrying capacity depends on the raceway angles of outer ring, and the more big bearing capacity of angle is more big.The overwhelming majority adopts single-row tapered roller bearings, can't tackle the high-revolving requirement of high load, because bearing capacity is lower, in usability with have certain influence working life, in addition, play needs the user to adjust when mounted, and is cumbersome.In addition, because lubrication effect is poor, long-term rotation at a high speed causes bearing breaking easily, and working life is short.
The model utility content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of high lubricating effect, the Biserial cylindrical roller bearing of long service life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of lubricating type Biserial cylindrical roller bearing, comprise bearing outer ring, bearing inner race, cylindrical roller and retainer, have two line column rollers, described bearing outer ring and bearing inner race are separately positioned on the inside and outside both sides of cylindrical body of cylindrical roller and retainer formation, and described bearing outer ring center offers oil hole.
Further, described bearing outer ring surface is provided with locking groove.
The beneficial effects of the utility model are, lubricating type Biserial cylindrical roller bearing bearing capacity of the present utility model is stronger, and load carrying capacity is big, high lubricating effect, and it is little to rub, and is suitable for rotation at a high speed, flexible operation, rigidity is strong, high life.
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.
1. bearing outer rings among the figure, 2. bearing inner race, 3. cylindrical roller, 4. oil hole.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation 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.
Lubricating type Biserial cylindrical roller bearing as shown in Figure 1, comprise bearing outer ring 1, bearing inner race 2, cylindrical roller 3 and retainer, have two line column rollers 3, bearing outer ring 1 and bearing inner race 2 are separately positioned on the inside and outside both sides of cylindrical body of cylindrical roller 3 and retainer formation, and bearing outer ring 1 center offers oil hole 4.Bearing outer ring 1 surface is provided with locking groove.
Be enlightenment with above-mentioned foundation desirable embodiment of the present utility model, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.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.
