Abstract
The utility model discloses a kind of bearing holder, comprise: retainer body, and at internal circular surfaces circumferentially equally distributed some grooves of described retainer body, described groove is circular arc or rectangle, is Spielpassung between the internal diameter of described retainer body and the inner ring external diameter of bearing.By the way, the utility model can make retainer operationally be guided reliably, ensures to work reposefully, thus extends the operating life of the bearing installing this type of retainer.
Description
Technical field
The utility model relates to Bearing fittings field, particularly relates to a kind of bearing holder.
Background technique
As shown in Figure 1, be a kind of common selfaligning roller bearing, it is made up of outer ring (1), inner ring (2), two rows' rolling element (3) and retainer body (4).Wherein the effect of retainer body (4) is even partition rolling element, and along with rolling element is around the rotation of bearing centre axle, guides rolling element smooth working.In order to realize above-mentioned functions, the motion of retainer self must be steadily, Here it is is realized by the internal circular surfaces (5) of retainer body and the outer round surface (6) of inner ring, have the gap (see figure 2) that very little between the internal circular surfaces (5) of retainer body and the outer round surface (6) of inner ring, retainer is guided to have come by this gap by inner ring.In reality uses, because excessive gap makes to guide unstable, and too small gap retainer and inner ring will collision frictions, and cause noise to increase or early failue, be this type of retainer problem in use always.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of bearing holder, and retainer can be made operationally to be guided reliably, ensures to work reposefully, thus extends the operating life of the bearing installing this type of retainer.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of bearing holder, comprise: retainer body, and at internal circular surfaces circumferentially equally distributed some grooves of described retainer body, described groove is circular arc or rectangle, is Spielpassung between the internal diameter of described retainer body and the inner ring external diameter of bearing.
In the utility model preferred embodiment, described groove is by middle one section of circular arc and the monosymmetric rectilinear(-al) of described circular arc.
In the utility model preferred embodiment, the gap between the internal diameter of described retainer body and the inner ring external diameter of bearing is 0.1-0.2mm.
In the utility model preferred embodiment, described bearing is selfaligning roller bearing.
The beneficial effects of the utility model are: be circumferentially uniformly distributed some grooves by the internal circular surfaces at retainer body, and be designed to Spielpassung by between the internal diameter of retainer body and the inner ring external diameter of bearing, the lubricating grease in groove is made to form lubricant film at the internal circular surfaces of retainer body and the outer round surface of inner ring, effectively can separate the internal circular surfaces of retainer body and the outer round surface of inner ring, they are not contacted, thus can not friction be produced, abnormal sound can not be sent, the noise of bearing and temperature rise are greatly improved, retainer stable working, bearing life is longer.
Accompanying drawing explanation
Fig. 1 is the structural representation of selfaligning roller bearing common at present;
Fig. 2 is the partial enlarged drawing of A shown in Fig. 1;
Fig. 3 is the partial schematic diagram of a kind of bearing holder one of the utility model preferred embodiment;
Fig. 4 is the schematic diagram shown in Fig. 3;
In accompanying drawing, the mark of each parts is as follows: 1, outer ring, and 2, inner ring, 3, rolling element, 4, retainer body, 5, the internal circular surfaces of retainer body, 6, the outer round surface of inner ring, 7, circular arc, 8, straight line.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 3 and Fig. 4, the utility model is embodiment comprise:
A kind of bearing holder, comprise: retainer body 4, and at internal circular surfaces 5 circumferentially equally distributed some grooves of described retainer body, described groove is circular arc or rectangle, be Spielpassung between the external diameter of the internal diameter of described retainer body 4 and the inner ring 2 of bearing, the gap between the external diameter of the internal diameter of described retainer body 4 and the inner ring 2 of bearing is preferably 0.1-0.2mm.
Described groove is made up of middle one section of circular arc 7 and the monosymmetric straight line 8 of described circular arc 7, be evenly distributed on the internal circular surfaces 5 of described retainer body circumferentially, several can be set according to actual conditions, after bearing assemble or before using, in these grooves of the internal diameter of retainer body 4, inject lubricating grease.
Described bearing is selfaligning roller bearing, also can be the bearing of other types.
When reality uses as shown in Figure 4, when inner ring 2 rotates in the clockwise direction, because the frictional force between the outer round surface 6 of inner ring and lubricating grease can with the lubricating grease flowing in the groove on the internal circular surfaces 5 of retainer body, during lubricating grease flowing, a part enters the gap between the outer round surface 6 of retainer body 4 and inner ring, lubricant film is formed on surface, effectively can separate the internal circular surfaces 5 of retainer body and these two surfaces of outer round surface 6 of inner ring, they are not contacted thus can not friction be produced, abnormal sound can not be sent, and make retainer body 4 more flexible when inner ring 2 rotates due to the lubricant film between their surfaces, stable and smooth and easy, noise also can reduce greatly.After the rotating speed of bearing promotes, the grease in the groove on the internal circular surfaces 5 of retainer body also can, because of hydrokinetics reason, make retainer body 4 form the effect of automatic centering, more stable after rotation.
When bearing adopts grease lubrication, the groove on the internal circular surfaces 5 of retainer body also plays the effect of storing lubricating grease, constantly can throw away the lubrication that lubricating grease participates in bearing in bearing working under centrifugal action.
The utility model discloses a kind of selfaligning roller bearing retainer, some grooves are circumferentially uniformly distributed by the internal circular surfaces at retainer body, and be designed to Spielpassung by between the internal diameter of retainer body and the inner ring external diameter of bearing, the lubricating grease in groove is made to form lubricant film at the internal circular surfaces of retainer body and the outer round surface of inner ring, effectively can separate the internal circular surfaces of retainer body and the outer round surface of inner ring, they are not contacted, thus can not friction be produced, abnormal sound can not be sent, the noise of bearing and temperature rise are greatly improved, retainer stable working, bearing life is longer.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
