Abstract
The utility model discloses a kind of selflubricating biserial conical bearing, be made up of the first inner ring of outer ring and docking, the second inner ring, it is characterized in that, the endoporus of described first inner ring and the second inner ring is cylindrical hole, the outer edge surface of the first inner ring and the second inner ring is conical surface, and butt end is osculum end; The first solid lubricating film is coated with at the outer edge surface of described first inner ring and the second inner ring; The outer edge surface of described outer ring is cylndrical surface, and the endoporus of outer ring is two conical bores of the minimum symmetry of mid point position diameter, is coated with the second solid lubricating film at the wall of described outer ring endoporus; The tapering of two conical surfaces of described outer ring endoporus is consistent with the tapering of the outer edge surface of the first inner ring and the second inner ring respectively.Solve the problems such as existing single row conical bearing running accuracy is low, maintenance cost is high.
Description
Technical field
The utility model belongs to technical field of bearings, especially a kind of selflubricating biserial conical bearing.
Background technique
Common biserial conical bearing is double-row conical bearing, can bear larger radial load and two-way thrust load, and it is widely used in gear-box, crane gear, rolling mill and mine mechanism such as rock tunnel(ling) machine.But this bearing structure is complicated, difficulty of processing is large, and cost of production is high, needs oiling agent during running, and maintenance cost is high.The retainer of double-row conical bearing is difficult to precision machining, the running accuracy affecting bearing because retainer precision is low simultaneously.
Model utility content
The purpose of this utility model will provide a kind of selflubricating biserial conical bearing exactly, to solve the problems such as existing biserial conical bearing running accuracy is low, maintenance cost is high.
In order to realize foregoing invention object, the utility model adopts following technological scheme:
Selflubricating biserial conical bearing, be made up of the first inner ring of outer ring and docking, the second inner ring, the endoporus of described first inner ring and the second inner ring is cylindrical hole, and the outer edge surface of the first inner ring and the second inner ring is conical surface, and butt end is osculum end; The first solid lubricating film is coated with at the outer edge surface of described first inner ring and the second inner ring; The outer edge surface of described outer ring is cylndrical surface, and the endoporus of outer ring is two conical bores of the minimum symmetry of mid point position diameter, is coated with the second solid lubricating film at the wall of described outer ring endoporus; The tapering of two conical surfaces of described outer ring endoporus is consistent with the tapering of the outer edge surface of the first inner ring and the second inner ring respectively.
Selflubricating biserial conical bearing designed by the utility model, the outer edge surface of the internal face in outer ring, the first inner ring, the second inner ring is respectively arranged with solid lubricating film, it can not affect dimensional accuracy and the tolerance fit of part, and, a little lubriation material can plate very large size, the quality of the lubricating film formed is also better, and thus Economy is better.In addition, in using process, do not need oiling agent, not only eliminate pollution sources, also reduce production and maintenance cost.Meanwhile, because can friction factor be effectively reduced, can also increase the service life.
The selflubricating biserial conical bearing structure of the utility model design is simple, without rolling element, without retainer, and selflubricating.Because not needing retainer, so the precision avoided because of retainer affects the problem of bearing accuracy not, effectively improve the running accuracy of bearing.Again because the way of contact of selflubricating biserial conical bearing of the present utility model is face contact, compared with the double-row conical bearing being linear contact lay with the way of contact, bearing capacity of the present utility model is higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the basic structure of selflubricating biserial conical bearing of the present utility model is made up of the first inner ring 1, second inner ring 2 of outer ring 3 and docking.
The endoporus of described first inner ring 1 and the second inner ring 2 is cylindrical hole, and the outer edge surface of the first inner ring 1 and the second inner ring 2 is conical surface, and butt end is osculum end; The first solid lubricating film 4 is coated with at described first inner ring 1 and the second inner ring 2 outer edge surface.The outer edge surface of described outer ring is cylndrical surface, and the endoporus of outer ring is two conical bores of the minimum symmetry of mid point position diameter, is coated with the second solid lubricating film 5 at the wall of described outer ring endoporus; The tapering of two conical surfaces of described outer ring 3 endoporus respectively and the tapering of the outer edge surface of first inner ring 1 corresponding with its position and the second inner ring 2 consistent.
Described solid lubricating film can adopt the method for ion plating to complete coating, to reach strong adhesion, and the requirement that coating is not only thin but also even.
