Abstract

The utility mode relates to a rolling body, in particular to a spherical rolling body capable of reducing occupied space. Planes (2) are respectively arranged on two sides of the spherical rolling body (1). Circular recessions (3) are respectively arranged on the planes (2) on two sides of the spherical rolling body (1), the two circular recessions (3) are communicated through an oil storage hole (4), and the oil storage hole (4) is located at the central portion of the two circular recessions. The circular recessions are arranged on the planes at two sides of the spherical rolling body, and the oil storage hole penetrating through the central positions of the two circular recessions is arranged, therefore, the spherical rolling body capable of reducing the occupied space can greatly improve loadability, prolong service life of a bearing, increase oil storage amount in the bearing, and effectively reducing bearing wear accidents.

Description

The spherical rolling element that a kind of minimizing takes up room

[technical field]

The utility model relates to a kind of rolling element, especially relates to the spherical rolling element that a kind of minimizing takes up room.

[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 Hanover has abroad 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; 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, certainly will cause the minimizing of interior lubricant oil of bearing or Lubricants containing quantity, be unfavorable for that the wearing and tearing of rolling element alleviate.

[summary of the invention]

In order to overcome the deficiency in the background technique; The utility model discloses the spherical rolling element that a kind of minimizing takes up room, make its not only remarkable lifting load rate, prolong bearing working life; And can effectively increase the oil reserve in the bearing, reduce the generation of bearing wear accident.

For realizing the foregoing invention purpose, the utility model adopts following technological scheme:

The spherical rolling element that a kind of minimizing takes up room, the both sides of spherical rolling element all have the plane; On the plane of spherical rolling element both sides, all have circular depressed, be communicated with through oil storage hole between two circular depressed, described oil storage hole is positioned at the center portion of two circular depressed.

The spherical rolling element that a kind of minimizing takes up room, the aperture of said oil storage hole are less than or equal to 1/5th of the maximum outside diameter of spherical rolling element.

Owing to adopted technique scheme, the utlity model has following beneficial effect:

The spherical rolling element that a kind of minimizing that the utility model proposes takes up room; Through on two side planes of spherical rolling element, circular depressed being set; And the oil storage hole that connects two circular depressed center portions is set; Because oil storage hole is spherical below 1/5th or 1/5th of outside diameter of rolling element maximum, the intensity of spherical rolling element is constant basically; The utility model is remarkable lifting load rate not only, prolongs bearing working life, and has increased the oil reserve in the bearing, reduces the generation of bearing wear accident effectively.

Fig. 2 is the structural representation of the utility model;

Among the figure: 1, spherical rolling element; 2, plane; 3, circular depressed; 4, 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;

In conjunction with accompanying drawing 1, accompanying drawing 2; The spherical rolling element that a kind of minimizing takes up room; The both sides of spherical rolling element 1 have plane 2; Be communicated with all having on the plane 2 of spherical rolling element 1 both sides between circular depressed 3, two circular depressed through oil storage hole 4, described oil storage hole 4 is positioned at the center portion of two circular depressed.

Implement the spherical rolling element that the described a kind of minimizing of the utility model takes up room; Through on two side planes 2 of spherical rolling element 1, circular depressed 3 being set; And the oil storage hole 4 that connects two circular depressed center portions is set; Because the aperture of oil storage hole 4 is merely below 1/5th or 1/5th of spherical rolling element 1 maximum outside diameter, makes that the intensity of spherical rolling element 1 is constant basically.

The utility model does not detail part and is existing technology.
