Abstract
The utility model relates to a rolling element, which provides a rolling element with double balls connected together and is formed by two spherical rolling elements with the same shape. Two end faces of the rolling element with double balls connected together are planes and respectively provided with oil storage holes (2) which are communicated with each other. The rolling element with double balls connected together is formed by two spherical rolling elements with the same shape, thereby saving space in a bearing, achieving technical effect of reducing abrasion of a retainer and prolonging service life of the bearing.
Description
[technical field]
The utility model relates to a kind of rolling element, especially relates to the rolling element of a kind of pair of ball disjunctor.
[background technique]
Known, spherical rolling element is one of main member of bearing industry, and what that is to say most of bearings uses is spherical rolling element; Because the surface of contact of spherical rolling element and bearing enclose only is line of annular of spherical rolling element; So load is not just born at other position; The zone that external Hanover has attempted using with spherical rolling element all not bear load all is cut; So just mean that spherical rolling element has respectively excised 15% from the two ends of diameter; The spheroid of then realizing spherical rolling element is narrower 30% than circular, has reached significantly conserve space and in same space, has increased more rolling element, just realizes that through two retainers the spherical rolling element after two row's cuttings bears load synchronously; What bring thus is remarkable lifting load rate, and makes bearing obtain longer service life; Yet under the situation that the sphere rolling scale of construction increases, the pocket hole number of retainer also increases synchronously, causes the increase of cost to be unfavorable for that also the wearing and tearing of spherical rolling element and retainer alleviate.
[summary of the invention]
In order to overcome the deficiency in the background technique; The utility model discloses the rolling element of a kind of pair of ball disjunctor; The rolling element of the two ball disjunctors that propose not only can be practiced thrift the space in the bearing, and can realize alleviating the technique effect of wearing and tearing retainer, and makes bearing obtain longer service life.
For realizing the foregoing invention purpose, the utility model adopts following technological scheme:
The rolling element of a kind of pair of ball disjunctor is made up of two identical spherical rolling elements of shape, and the both ends of the surface of the rolling element of said pair of ball disjunctor are the plane.
Both ends of the surface at the rolling element of two ball disjunctors have oil storage hole respectively, are connectivity structure between the oil storage hole that the rolling element both ends of the surface had of two ball disjunctors.
The rolling element of a kind of pair of ball disjunctor, two spherical rolling elements are identical circular or oval.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
The rolling element of a kind of pair of ball disjunctor that the utility model proposes; Constitute by two identical spherical rolling elements of shape; The rolling element of said pair of ball disjunctor not only can be practiced thrift the space in the bearing, and has realized alleviating the technique effect of wearing and tearing retainer, and makes bearing obtain longer service life; Wherein can accumulate lubricant oil or lubricating grease in the oil storage hole, the lubricant oil or the lubricating grease that are beneficial to bearing replenish.

Fig. 1 is the perspective view of the utility model;
Fig. 2 is the structural representation of the utility model;
Among the figure: 1, spherical rolling element, 2, oil storage hole.
[embodiment]
Can explain in more detail that through following embodiment the utility model, the utility model are not limited to following embodiment, the purpose of open the utility model is intended to protect all variations and the improvement in the utility model scope;
Like Fig. 1, shown in Figure 2, the rolling element of a kind of pair of ball disjunctor is made up of two identical rolling elements 1 of shape, and the both ends of the surface of the rolling element of said pair of ball disjunctor are the plane; Both ends of the surface at the rolling element of two ball disjunctors have oil storage hole 2 respectively, are connectivity structure between the oil storage hole 2 that the both ends of the surface of the rolling element of two ball disjunctors had; Two spherical rolling elements are identical circular or oval, and among this embodiment, two spherical rolling elements are identical ellipse.
The rolling element of the described a kind of pair of ball disjunctor of the utility model; Constitute by two identical spherical rolling elements 1 of shape; The rolling element of said pair of ball disjunctor not only can be practiced thrift the space in the bearing, and has realized alleviating the technique effect of wearing and tearing retainer, and makes bearing obtain longer service life; Its both ends of the surface of the rolling element of said pair of ball disjunctor are the plane, have made things convenient for the installation of retainer and the wearing and tearing of minimizing rolling element and retainer; Wherein can accumulate lubricant oil or lubricating grease in the oil storage hole 2, the lubricant oil or the lubricating grease that are beneficial to bearing replenish.
Claims (3)
1. the rolling element of two ball disjunctors, it is characterized in that: be made up of two identical spherical rolling elements (1) of shape, the both ends of the surface of the rolling element of said pair of ball disjunctor are the plane.
2. the rolling element of a kind of pair of ball disjunctor according to claim 1 is characterized in that: the both ends of the surface at the rolling element of two ball disjunctors have oil storage hole (2) respectively, are connectivity structure between the oil storage hole that the both ends of the surface of the rolling element of two ball disjunctors had (2).
