Abstract
The utility model relates to the technical field of bearings, and particularly relates to a double-row tapered roller bearing. The double-row tapered roller bearing comprises a bearing outer ring, a bearing inner ring, a tapered roller and a cage, wherein the bearing inner ring is protruded out of the bearing outer ring, a space ring is arranged between the bearing outer ring and the bearing inner ring, and a tapered inner ring assembly consisting of the tapered roller and an inner ring of the cage assembly is of a separable structure. According to the double-row tapered roller bearing disclosed by the utility model, the tapered inner ring assembly is of the separable structure, therefore, the double-row tapered roller bearing is relatively convenient to install, simple in structure, capable of being used in a front-wheel hub of a car, strong in carrying capacity, large in load capacity, small in friction between the roller and a collar flange, and suitable for high-speed revolution.
Description
Technical field
The utility model relates to technical field of bearings, especially a kind of double-row conical 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.Common double-row conical bearing complex structure, the manufacture cost height, high load is high-revolving when requiring in reply, in case damage, repairs suitable trouble.
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 load big, the double-row conical bearing of long service life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of double-row conical bearing, comprise bearing outer ring, bearing inner race, tapered roller and retainer, described bearing inner race protrudes bearing outer ring, be provided with spacer ring between described bearing outer ring and the bearing inner race, the cone assembly that the inner ring of described tapered roller and retainer assembly is formed is separable structure.
Further, described tapered roller is contained between the recessed raceway and the recessed raceway on the bearing outer ring internal surface on the bearing inner race outer surface.
The beneficial effects of the utility model are, the cone assembly of double-row conical bearing of the present utility model is separable structure, install more convenient, simple in structure, can be used in the front-wheel hub of car, bearing capacity is stronger, and load carrying capacity is big, roller and the friction of lasso rib are little, are suitable for rotation at a high speed.
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. tapered roller, 4. spacer ring.
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.
Double-row conical bearing as shown in Figure 1, comprise bearing outer ring 1, bearing inner race 2, tapered roller 3 and retainer, bearing inner race 2 protrudes bearing outer ring 1, be provided with spacer ring 4 between bearing outer ring 1 and the bearing inner race 2, tapered roller 3 is separable structure with the cone assembly that the inner ring of retainer assembly is formed.Secondly, tapered roller 3 is contained between the recessed raceway and the recessed raceway on bearing outer ring 1 internal surface on bearing inner race 2 outer surfaces.
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.
Claims (2)
