Abstract
The utility model relates to a kind of high-speed angular contact ball bearing with outer guiding retainer, comprise outer ring, inner ring, rolling element and retainer, described retainer is arranged between inner ring and outer ring, described retainer has the mounting hole can inlaying rolling element, this retainer external diameter is provided with the groove that can store oil, this groove is positioned at the top of mounting hole, the utility model structure is simple, by arranging groove in retainer outer radius, lubricating grease can be deposited in groove, play the effect in deposit fat source, thus extend time of using in bearing of lubricating grease and life-span, and main shaft temperature rise can be made to reduce by 10%, bearing operation speed improves 10%, the life-span of retainer can extend more than 20%, the utility model is reasonable in design, can promote the use of.
Description
Technical field
The utility model relates to technical field of bearings, particularly relates to a kind of high-speed angular contact ball bearing with outer guiding retainer.
Background technique
Along with the fast development of domestic and international High Speed NC Machine Tools, the high-speed machine tool main shaft bearing supporting for it becomes development trend, adopts the angular contact ball bearing of grease lubrication, uses pnenolic aldehyde bakelite holder, is usually all applied in dmn > 1 × 10
4on the drive mechanism of mmr/min, but find in the practice of Long-Time Service, change along with bearing lubrication state is bad or lose, when bearing temperature rise is more than more than 40 DEG C, the accelerated wear test of retainer can be caused, and even the lintel of last retainer causes fracture, this is a kind of form that in the failure mode that usually occurs of high-speed angular contact ball bearing, proportion is maximum.
In practicality, most of high-speed angular contact ball bearing uses solid cage usually all to adopt the outer structural type guided, owing to guiding, so the quality of lubricating condition is the key determining retainer working life by the outer internal diameter centering of bearing outer ring.
Model utility content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide one can lay in fat source, and the band extending the service time of lubricating grease in bearing guides the high-speed angular contact ball bearing of retainer outward.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of high-speed angular contact ball bearing with outer guiding retainer, comprise outer ring, inner ring, rolling element and retainer, described retainer is arranged between inner ring and outer ring, described retainer has the mounting hole can inlaying rolling element, this retainer external diameter is provided with the groove that can store oil, and this groove is positioned at the top of mounting hole.
Further, inside described outer ring, be provided with raceway, be provided with raceway outside described inner ring and correspond.
Further, between described inner ring and outer ring, be provided with dual face seals circle, to reach good sealing effect.
Compared with prior art, the utility model has the advantage of: the utility model structure is simple, by arranging groove in retainer outer radius, lubricating grease can be deposited in groove, play the effect in deposit fat source, thus extend time of using in bearing of lubricating grease and life-span, and main shaft temperature rise can be made to reduce by 10%, bearing operation speed improves 10%, and the life-span of retainer can extend more than 20%, the utility model is reasonable in design, can promote the use of.

Fig. 2 is retainer local structural graph of the present utility model;
Fig. 3 is partial sectional view of the present utility model.
Embodiment
As Figure 1-3, a kind of high-speed angular contact ball bearing with outer guiding retainer, comprise outer ring 1, inner ring 2, rolling element 3 and retainer 4, described retainer 4 is arranged between inner ring 2 and outer ring 1, raceway is provided with inside described outer ring 1, be provided with raceway outside described inner ring 2 to correspond, dual face seals circle 5 is provided with between described inner ring 2 and outer ring 1, to reach good sealing effect, described retainer 4 has the mounting hole 6 can inlaying rolling element 3, this retainer 4 external diameter is provided with the groove 7 that can store oil, this groove 7 is positioned at mounting hole 6 top, the setting of groove 7 does not destroy the intensity of retainer 4.
During use, in the start of run stage of bearing, major part lubricating grease is extruded raceway very soon, there are some lubricating grease can be stacked in the groove 7 of retainer 4 external diameter, along with bearing High Rotation Speed, and a profile is formed in groove 7, on the end cap that all the other some greases may be thrown to seal ring 5 or other positions of bearing, along with by the rolling element 3 rotated, the lubricating grease near raceway being brought in raceway, also have a small amount of lubricating grease to be successively discharged, but it still has partial lubrication fat and is trapped in the groove 7 of retainer 4, along with the bearing running time lengthens gradually, the lubricating grease being distributed in rolling element 3 and raceway contact point is just slowly depleted, the lubricating grease retained in groove 7 is made to start heating, expand, softening, thus make partial lubrication fat be spread upon rolling element 3 surface by dilution, play the effect of lubricating grease needed for supplementary bearing.
The utility model structure is simple, by arranging groove in retainer outer radius, lubricating grease can be deposited in groove, play the effect in deposit fat source, thus extend time of using in bearing of lubricating grease and life-span, and main shaft temperature rise can be made to reduce by 10%, bearing operation speed improves 10%, the life-span of retainer can extend more than 20%, and the utility model is reasonable in design, can promote the use of.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technological scheme described in foregoing embodiments, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment's technological scheme of the utility model.
