Abstract
The utility model proposes a kind of bearing, this bearing comprises: outer ring, and outer surface is provided with wearing layer, and the hardness of wearing layer is higher than the hardness of the material in outer ring own; Supporting frame, ringwise, supporting frame is connected with inner surface; Rolling element, rolling element is multiple, and multiple rolling element is all installed in rotation on supporting frame, and the internal surface of rolling element is formed and is coupling tactile surface of contact.The utility model bearing enhances bearing wear resistance, thus extends the working life of bearing.
Description
Technical field
The utility model relates to mechanical parts technical field, refers to a kind of bearing especially.
Background technique
In the prior art, the bearing that fork truck uses, because of the frequent friction with the external world, causes bearing outer wall serious wear, needs often to change bearing, affects manufacturing efficiency.
Model utility content
The utility model proposes the bearing that a kind of appearance is wear-resisting.
The technical solution of the utility model is achieved in that
The utility model provides a kind of bearing, comprising: outer ring, and outer surface is provided with wearing layer, and the hardness of wearing layer is higher than the hardness of the material in outer ring own; Supporting frame, ringwise, supporting frame is connected with inner surface; Rolling element, rolling element is multiple, and multiple rolling element is all installed in rotation on supporting frame, and the internal surface of rolling element is formed and is coupling tactile surface of contact.
Further, the wearing layer of outer ring is formed by heat treatment.
Further, supporting frame offers multiple mounting hole equably, a rolling element is all installed in each mounting hole.
Further, rolling element is needle roller, and multiple needle roller be arranged in parallel on supporting frame.
Further, be provided with annular groove inside outer ring, rolling element is partly arranged in groove.
Bearing of the present utility model is provided with wearing layer on the surface of outer ring, bearing is when contacting with remaining part, can first be contacted with these parts by wearing layer, hardness due to wearing layer is higher than the hardness of the material in outer ring own, therefore the deterioration of wearing layer is less than the deterioration of outer ring, so add the wear resistance of bearing, thus extend the working life of bearing.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the schematic front view of the embodiment of a kind of bearing of the utility model; And
Fig. 2 is that the A of the bearing of Fig. 1 is to sectional view.
In figure:
10, outer ring; 11, groove, 20, supporting frame; 30, rolling element.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
In conjunction with see Fig. 1 to Fig. 2, as can be seen from the figure, the bearing of the present embodiment comprises outer ring 10, supporting frame 20 and rolling element 30.Wherein, the outer surface of outer ring 10 is provided with wearing layer, and the hardness of wearing layer is higher than the hardness of the material in outer ring 10 own, supporting frame 20 is connected to the inner side of outer ring 10, and multiple rolling element 30 is installed on supporting frame 20, rolling element 30 is arranged rotationally on supporting frame 20, and the internal surface away from outer ring 10 of rolling element 30 defines and the tactile surface of contact that is coupling.
The bearing of the present embodiment is provided with wearing layer on the surface of outer ring 10, bearing is when contacting with remaining part, can first be contacted with these parts by wearing layer, hardness due to wearing layer is higher than the hardness of the material in outer ring 10 own, therefore the deterioration of wearing layer is less than the deterioration of outer ring 10, so add the wear resistance of bearing, thus extend the working life of bearing.
Wearing layer in the present embodiment heat-treats acquisition preferably by outer ring 10.Skin is heat-treated, the alignment of crystal mode in outer ring 10 can be changed, the outermost intensity of outer ring 10 is strengthened.
For making rolling element 30 contact with axle better, supporting frame 20 offers multiple mounting hole equably, a rolling element 30 is all installed in each mounting hole, and all be arranged in parallel on supporting frame 20 between every two rolling elements 30.Preferably, rolling element 30 is needle roller.Adopting the bearing of this structure, can be for linear contact lay between needle roller and axle, and many Line of contact all with the axis being parallel of axle.When axle rotates, each needle roller together can rotate under the drive of axle, to reduce the friction between needle roller and axle, extends the working life of bearing.
In the present embodiment, offer groove 11 in the inner side of outer ring 10, groove 11 entirety ringwise.Being arranged in groove 11 of rolling element 30 part.Preferably, roll between the and the bottom land of groove 11 and should leave certain space, to prevent from rubbing between rolling element 30 and outer ring 10, the performance of raising bearing.
The bearing of the present embodiment, is preferably employed in turning between pontic and vertical shaft of fork truck.Bearing is arranged on the mounting hole being positioned at and turning on pontic, and turns between pontic and spindle and be connected by rotating shaft, and the first end of rotating shaft is connected with turning to pontic, and the second end of rotating shaft is located in bearing.When turn to there is relative movement between pontic and spindle time, can rub between bearing and axle, rub between bearing and installation hole wall, and adopt the bearing in the present embodiment, rub between bearing and axle, make the wear extent of axle be greater than the wear extent of bearing, so axle is relative and bearing is more easily damaged, replacing axle part inexpensively that like this can be regular, reduces and changes bearing or other the expensive component supporting with bearing, to reduce the maintenance cost of fork truck.Simultaneously, friction between bearing and back axle, due to the heat treatment of bearing outer wall, makes the wear resistance of bearing outer wall be enhanced, and bearing can be worn and torn for a long time, and then to the abrasion deformation installing hole wall after preventing bearing outer wall to wear and tear, extend the working life of back axle.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
