Abstract
A kind of Novel double-ball pocket hub-bearing unit retainer, belongs to technical field of bearings, and it is poor that the existing pair of ball pocket hub bearing retainer exists versatility, do not have the defect that enough interval supplying lubricating greases lubricate between pocket groove and steel ball.The utility model comprises circumferential base, circumferential base is circumferentially provided with equally distributed multiple pocket groove, pocket groove comprises the first holding cavity and the second holding cavity, two holding cavities are separately installed with the first steel ball and the second steel ball, first holding cavity is match with the first steel ball spherical, first steel ball is installed in this first holding cavity and can not moves in the axial direction, second holding cavity both ends open, one end open and the first holding cavity through, the other end opening is pocket groove notch, the diameter at the both ends open place of the second holding cavity is all less than the diameter of the second steel ball, second holding cavity distance is axially greater than the diameter of the second steel ball, between adjacent two pocket grooves, a grease groove is set.The utility model achieves good lubrication effect, and versatility is good.
Description
Technical field
The utility model belongs to technical field of bearings, especially relevant with a kind of Novel double-ball pocket hub-bearing unit retainer.
Background technique
Two ball pocket hub bearing generally comprises bearing outer ring, bearing inner race, retainer and steel ball rolling body, steel ball rolling body is installed between bearing inner race and bearing outer ring by retainer, in bearing operation process, drive steel ball operates, the retainer of existing pair of ball pocket hub bearing is generally a circumferential base, circumferential base is provided with equally distributed multiple pocket groove, two holding cavities are provided with in pocket groove, two steel balls that two accommodating matching size of holding cavity difference close, the bearing that existing retainer can only be suitable for same model is installed, versatility is poor, and cost is higher; Further, lubricating grease is more difficult when bearing High Rotation Speed accomplishes timely lubrication to steel ball not have sufficient gap to make between steel ball and retainer, and the time one is long, causes pivot friction to aggravate, and bearing temperature rises, and reduces the working life of bearing.
Model utility content
It is poor that the purpose of this utility model is intended to overcome existing pair of ball pocket hub bearing retainer versatility, the defect not having enough interval supplying lubricating greases to lubricate between pocket groove and steel ball, the Novel double-ball pocket hub-bearing unit retainer providing a kind of high lubricating effect, versatility good.
For this reason, the utility model is by the following technical solutions: a kind of Novel double-ball pocket hub-bearing unit retainer, comprise circumferential base, circumferential base is circumferentially provided with equally distributed multiple pocket groove, it is characterized in that, described pocket groove notch is arranged towards circumferential base axial direction, pocket groove comprises the first holding cavity and the second holding cavity, first steel ball is installed in the first holding cavity, second steel ball is installed in the second holding cavity, first holding cavity is match with the first steel ball spherical, first steel ball is installed in this first holding cavity and can not moves in the axial direction, second holding cavity both ends open, one end open and the first holding cavity through, the other end opening is described pocket groove notch, the diameter at the both ends open place of the second holding cavity is all less than the diameter of the second steel ball, pocket groove notch can not be skidded off when second steel ball is loaded in the second holding cavity, second holding cavity distance is axially greater than the diameter of the second steel ball, can move in the axial direction when second steel ball is loaded in the second holding cavity, second steel ball of different model can be installed, arrange a U-shaped grease groove between described adjacent two pocket grooves, lubricating grease is lubricated the steel ball in pocket groove by U-shaped grease groove, reduces the friction of steel ball and the inside and outside circle of bearing.
The utility model can reach following beneficial effect: 1, by arranging the first mutually through holding cavity and the second holding cavity in pocket groove, two steel balls are loaded in two holding cavities respectively, wherein the second holding cavity has mobile space in the axial direction, second steel ball of different model can be installed, versatility is good, and reduces cost of production; 2, by arranging a U-shaped grease groove between adjacent two pocket grooves, lubricating grease is lubricated the steel ball in pocket groove by U-shaped grease groove, reduces the friction of steel ball and the inside and outside circle of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises circumferential base, circumferential base is circumferentially provided with equally distributed multiple pocket groove, described pocket groove notch is arranged towards circumferential base axial direction, pocket groove comprises the first holding cavity 2 and the second holding cavity 3, first steel ball 1 is installed in first holding cavity 2, second steel ball 5 is installed in second holding cavity 3, first holding cavity 2 is spherical for what match with the first steel ball 1, first steel ball 1 is installed in this first holding cavity 2 and can not moves in the axial direction, second holding cavity 3 both ends open, one end open and the first holding cavity 2 through, the other end opening is described pocket groove notch, the diameter at the both ends open place of the second holding cavity 3 is all less than the diameter of the second steel ball 5, pocket groove notch can not be skidded off when second steel ball 5 is loaded in the second holding cavity 3, second holding cavity 3 distance is in the axial direction greater than the diameter of the second steel ball 5, can move in the axial direction when second steel ball 5 is loaded in the second holding cavity 3, second steel ball 5 of different model can be installed, arrange a U-shaped grease groove 4 between described adjacent two pocket grooves, lubricating grease is lubricated by the steel ball in U-shaped grease groove 4 pairs of pocket grooves, reduces the friction of steel ball and the inside and outside circle of bearing.
