Abstract
The utility model relates to technical field of bearings, is specifically deep groove ball bearing retainer.The scheme that the utility model adopts is: a kind of deep groove ball bearing retainer, include waveform and keep support body, waveform keeps support body is along the circumferential direction distributed with some ball pockets, and the Kong Liang between adjacent ball pocket, described ball pocket top is provided with the convex closure arched upward outwardly, is positioned at convex closure corresponding part and forms oil storage grooves in corresponding described ball pocket.Compared with prior art, have steel ball high lubricating effect, friction area is few for the utility model, start and running torque little, run stability is good, generates heat less and the large advantage of intensity.
Description
Technical field
The utility model relates to technical field of bearings, particularly deep groove ball bearing retainer.
Background technique
Deep groove ball bearing is
rolling bearingin a most common type.The deep groove ball bearing of basic model is by an outer ring, and an inner ring, one group of steel ball and one group of retainer are formed.The retainer structure that deep groove ball bearing uses is, comprises waveform and keeps support body, and waveform keeps support body to be provided with ball pocket and the Kong Liang between ball pocket.The pocket hole structure design of existing deep groove ball bearing retainer is unreasonable, there is steel ball and ball pocket area of contact greatly, and in steel ball and ball pocket, wall friction is large; Between steel ball and ball pocket, lubrication effect is poor; Thus cause bearing operation poor stability, the problems such as the life-span is short, and the comparatively large and noise of heating is large.
For solving the problem, existing general way designs oil-bearing structure in ball pocket hole, existing oil-bearing structure has the design such as fluting, pit, but it is only paid close attention to the greasy property between steel ball and ball pocket and reduces friction area, or there is the defect such as the decline of retainer intensity or steel ball run stability difference.
Summary of the invention
Goal of the invention of the present utility model is: for overcoming the defect that prior art exists, the deep groove ball bearing retainer that the utility model provides a kind of oil-bearing structure reasonable in design, there is steel ball high lubricating effect, friction area is few, start and running torque little, run stability is good, and heating less and the large advantage of intensity.
For achieving the above object, the utility model provides following technological scheme: a kind of deep groove ball bearing retainer, include waveform and keep support body, waveform keeps support body is along the circumferential direction distributed with some ball pockets, and the Kong Liang between adjacent ball pocket, it is characterized in that: described ball pocket top is provided with the convex closure arched upward outwardly, be positioned at convex closure corresponding part in corresponding described ball pocket and form oil storage grooves.
By adopting technique scheme, oil-bearing structure adopts convex closure design and form oil storage grooves, and oil storage grooves is convenient to the storage of lubricant oil, improve steel ball lubrication effect, reduce the area of contact of ball pocket and steel ball simultaneously, reduce friction, ensure run stability, reduce noise, reduce starting torque and the running torque of bearing, and under convex closure design, ensure that retainer is overall, ensure retainer working strength, improve working life; Convex closure is positioned at ball pocket top, and the contact of steel ball and ball pocket is closer to the middle part of steel ball, i.e. the maximum diameter place of steel ball, makes the operation of steel ball more steady, reduce noise.
The utility model is set to further: described convex closure is the long strip extended along ball pocket distribution arrangement, and corresponding described oil storage grooves is the long strip extended along ball pocket distribution arrangement.
By adopting technique scheme, the length direction of oil storage grooves is consistent with the direction of steel ball rolling, ensures the middle part of contact closer to steel ball of steel ball and ball pocket further, improves run stability and the lubrication effect of steel ball.
The utility model is set to further: between the edge tangent line of described ball pocket and Kong Liang, angle is 70 ° ~ 80 °.
By adopting technique scheme, reducing the area of contact of steel ball and ball pocket, reducing friction and heating, and ensureing the stability of steel ball running.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the ball pocket structural representation one of the utility model specific embodiment deep groove ball bearing retainer;
Fig. 2 is the ball pocket structural representation two of the utility model specific embodiment deep groove ball bearing retainer;
Fig. 3 is the ball pocket edge tangent line of the utility model specific embodiment deep groove ball bearing retainer and the linkage structure sketch of Kong Liang.
Embodiment
See accompanying drawing 1 and accompanying drawing 2, a kind of deep groove ball bearing retainer disclosed in the utility model, include waveform and keep support body, waveform keeps support body is along the circumferential direction distributed with some ball pockets 1, and the hole beam 2 between adjacent ball pocket 1, described ball pocket 1 top is provided with the convex closure 11 arched upward outwardly, is positioned at convex closure 11 corresponding part and forms oil storage grooves 12 in corresponding described ball pocket 1.Oil-bearing structure adopts convex closure design and form oil storage grooves, oil storage grooves is convenient to the storage of lubricant oil, improves steel ball lubrication effect, reduces the area of contact of ball pocket and steel ball simultaneously, reduce friction, ensure run stability, reduce noise, reduce starting torque and the running torque of bearing, and under convex closure design, guarantee retainer is overall, ensures retainer working strength, improves working life; Convex closure is positioned at ball pocket top, and the contact of steel ball and ball pocket is closer to the middle part of steel ball, i.e. the maximum diameter place of steel ball, makes the operation of steel ball more steady, reduce noise.Wherein, described convex closure 11 is the long strip extended along ball pocket 1 distribution arrangement, and corresponding described oil storage grooves 12 is the long strip extended along ball pocket distribution arrangement.The length direction of oil storage grooves is consistent with the direction of steel ball rolling, ensures the middle part of contact closer to steel ball of steel ball and ball pocket further, improves run stability and the lubrication effect of steel ball; And convex hull shape more meets the size of ball pocket, be processed to form conveniently.Certainly as the scheme that the utility model is feasible, convex closure also can be spherical cap shape, there is lubrication area few, also can be to extend along waveform maintenance support body radial direction, there is design inconvenience, and lubrication effect is poor and steel ball rotational stability defect; Therefore the preferential structural design adopting this specific embodiment.The profile of convex closure is circular arc, and this structural strength is large.
As shown in Figure 3, between the edge tangent line of described ball pocket 1 and hole beam 2, angle α is 70 ° ~ 80 °.Preferably 75 °.Reduce the area of contact of steel ball and ball pocket, reduce friction and heating.
Claims (3)
1. a deep groove ball bearing retainer, include waveform and keep support body, waveform keeps support body is along the circumferential direction distributed with some ball pockets, and the Kong Liang between adjacent ball pocket, it is characterized in that: described ball pocket top is provided with the convex closure arched upward outwardly, be positioned at convex closure corresponding part in corresponding described ball pocket and form oil storage grooves.
2. deep groove ball bearing retainer according to claim 1, is characterized in that: described convex closure is the long strip extended along ball pocket distribution arrangement, and corresponding described oil storage grooves is the long strip extended along ball pocket distribution arrangement.
