Abstract
The utility model provides a deep groove ball bearing, which belongs to the field of mechanical technology, which solves the problems of poor impact resistance, poor bearing capacity and the like of the existing deep groove ball bearing. The deep groove ball bearing comprises a bearing inner race, a bearing outer race and spherical roll balls with a retainer, wherein a raceway is arranged between the bearing inner race and the bearing outer race, and the roll balls are arranged in the raceway; the bearing outer race is provided with an upper concave arc groove, and the bearing inner race is provided with a lower concave arc groove; and a ball-adding opening is formed when the upper concave arc groove is opposite to the lower concave arc groove. The deep groove ball bearing has the advantages of simple structure, good using effect and high bearing capacity.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of bearing, particularly a kind of deep groove ball bearing.
Background technique
Bearing is widely used in the machinery rotation equipment, according to different classes of minute ball bearing, needle bearing etc.Wherein ball bearing is to use comparatively general bearing type.Deep groove ball bearing is the most frequently used rolling bearing, and it simple in structure, easy to use is mainly used to bear radial load, but when increasing bearing end-play, has the performance of certain angular contact ball bearing, can bear footpath, axial connected load.In that rotating speed is higher should not adopt thrust ball bearing again the time, also can be used to bear pure thrust load.Compare with other measure-alike types of bearings, this type of pivot friction coefficient is little, the limit speed height, but not shock-resistant, be not suitable for bearing heavy load.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of simple in structure, deep groove ball bearing that using effect is good.
The purpose of this utility model can realize by following technical proposal: a kind of deep groove ball bearing, comprise bearing inner race, bearing outer ring and have the spherical ball of retainer, be provided with raceway between described bearing inner race and the bearing outer ring and above-mentioned ball is positioned at this raceway, it is characterized in that, has a fovea superior curve bath on the described bearing outer ring, bearing inner race has a recessed curve bath, and described fovea superior curve bath forms a ball feeding mouth when relative with recessed curve bath position.
In above-mentioned deep groove ball bearing, described ball feeding mouth bore is slightly less than above-mentioned ball sphere diameter.
In above-mentioned deep groove ball bearing, described retainer is formed by fixedly connecting by two annular retaining sheets.Two annular retaining sheets forming retainer are fixed together, like this deep groove ball bearing in running, with regard to can not take place because of the operation that two annular retaining sheets come off or problem such as become flexible is brought undesired.
Compared with prior art, this deep groove ball bearing is provided with fovea superior curve bath and recessed curve bath respectively and forms ball feeding mouth on bearing inner race and bearing outer ring, can under the prerequisite that does not increase the solid bearing size dimension, increase the quantity of ball like this, thereby strengthen its radially bearing capacity, and do not influence external structures such as bearing support at all, have very strong economical.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a ball feeding mouth part schematic representation in the utility model.
Among the figure, 1, bearing inner race; 11, fovea superior curve bath; 2, bearing outer ring; 21, recessed curve bath; 3, ball; 4, retention tab; 5, raceway; 6, ball feeding mouth.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, this deep groove ball bearing comprises bearing inner race 1, bearing outer ring 2 and has the spherical ball 3 of retainer, the spherical ball 3 that is provided with raceway 5 and has a retainer between bearing inner race 1 and bearing outer ring 2 is positioned at this raceway 5, and wherein retainer is formed by fixedly connecting by two annular retaining sheets 4.Two annular retaining sheets 4 forming retainer are fixed together, like this deep groove ball bearing in running, with regard to can not take place because of the operation that two annular retaining sheets 4 come off or problem such as become flexible is brought undesired.
On bearing outer ring 2, have a fovea superior curve bath 11, have a recessed curve bath 21, when fovea superior curve bath 11 is relative with recessed curve bath 21 positions, between bearing inner race 1 and bearing outer ring 2, form a ball feeding mouth 6 at bearing inner race 1.By the setting of ball feeding mouth 6, can add at bearing and add spherical ball 3 from ball feeding mouth 6 under the heat expands state and break between bearing inner race 1 and the bearing outer ring 2, thereby strengthen its bearing capacity radially.This method is simple in structure, need not to change the bearing size dimension, can solve the inaccessible situation of common deep groove ball bearing bearing capacity, and does not influence external structures such as bearing support at all.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Claims (3)
1. deep groove ball bearing, comprise bearing inner race (1), bearing outer ring (2) and have the spherical ball (3) of retainer, be provided with raceway (5) between described bearing inner race (1) and the bearing outer ring (2) and above-mentioned ball (3) is positioned at this raceway (5), it is characterized in that, has a fovea superior curve bath (11) on the described bearing outer ring (2), bearing inner race (1) has a recessed curve bath (21), and described fovea superior curve bath (11) forms a ball feeding mouth (6) with recessed curve bath (21) when the position is relative.
2. deep groove ball bearing according to claim 1 is characterized in that, described ball feeding mouth (6) bore is slightly less than above-mentioned ball (3) sphere diameter.
3. deep groove ball bearing according to claim 1 and 2 is characterized in that, described retainer is formed by fixedly connecting by two annular retaining sheets (4).
