Abstract
The utility model discloses a rolling element of a self-aligning roller bearing. A through hole running through two ends of the rolling element is formed in the middle of the rolling element in an axial direction; inclined planes are arranged between two ends of the through hole and two end faces of the rolling element and are in circular arc transition with the ends of the through holes and the end faces of the rolling element. The rolling element disclosed by the utility model is simple in structure and reasonable in design, and is capable of effectively avoiding defects on a heart part of a conventional rolling element; the rolling element can generate trace elastic deformation to increase bearing shock resistance when the self-aligning roller bearing is under extreme load impact, and thus the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to technical field of bearings, relates in particular to a kind of rolling element for selfaligning roller bearing.
Background technique
In prior art, the rolling element of selfaligning roller bearing is biserial barrel shaped roller, and as shown in Figure 1, rolling element 1 is solid construction, and two ends are processed with depression 2.At present, large-scale rolling element processes through forging, due to the restriction of the conditions such as raw material or Forging Technology, rolling body-centered portion is more difficult, and compactness is poor, easily defectiveness, in the processes such as later stage heat treatment, easily crack, early failue, and also depression corner easily causes stress to concentrate.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide the rolling element for selfaligning roller bearing of a kind of reasonable in design, long service life.
For achieving the above object, the utility model adopts following technological scheme:
For a rolling element for selfaligning roller bearing, in the middle of its rolling element, along axial direction, be provided with the through hole through two ends, and be provided with inclined-plane between through hole two ends and rolling element both ends of the surface, inclined-plane and through hole end, rolling element end face are arc transition.
The above-mentioned rolling element for selfaligning roller bearing, the angle of its inclined-plane and rolling element end face is 10～15 °.
Owing to adopting technological scheme as above, the utlity model has following superiority:
Should be for the rolling element of selfaligning roller bearing, it is simple in structure, reasonable in design, the through hole arranging in the middle of rolling element can effectively be removed rolling element heart defect, and due to rolling body-centered portion hollow, when selfaligning roller bearing bears extreme loads impact, rolling element can produce micro-resiliently deformable, increase bearing impact resistance, thereby extended the working life of bearing; Between through hole two ends and rolling element both ends of the surface, adopt circular arc, inclined-plane, the transition of circular arc nature, the angle setting between inclined-plane and rolling element end face, has reduced the area of contact with rolling element end face, has solved the concentrated problem of rolling element two ends stress.
Accompanying drawing explanation
Fig. 1 is the structural representation of rolling element in prior art;
Fig. 2 is structural representation of the present utility model;
In figure: 1-rolling element; 2-depression; 3(a, b)-circular arc; 4-inclined-plane; 5-end face; 6-through hole.
Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 2, should be for the rolling element of selfaligning roller bearing, in the middle of its rolling element 1, along axial direction, be provided with the through hole 6 through two ends, and be provided with inclined-plane 4 between through hole two ends and rolling element both ends of the surface, two inclined-planes of the every one end of through hole are symmetrical along rolling element axial direction, inclined-plane and through hole end are through circular arc 3b transition, and inclined-plane and rolling element end face 5 are through circular arc 3a transition; The angle α of inclined-plane and rolling element end face is 10～15 °.
