Abstract
The invention discloses a bearing cage structure. A cage pocket (1) is arranged between adjacent cage beams (2), wherein a bump (4) of which the two ends are contacted with a rolling body (3) is arranged on the cage beam (2) in the cage pocket (1) along the direction vertical to the axial direction of the rolling body (3); the bump (4) enables a lubricating medium to conveniently enter the rolling surface of a bearing, so the lubricating effect is improved; and the two ends of the bump (4) are contacted with the rolling body (3), so the friction force of the rolling body (3) is reduced and the processing error is reduced.
Description
Technical field
The present invention relates to a kind of bearing cage structure, belong to bearing and make the field.
Background technique
Bearing can not get good lubricating, and causes bearing corrosion, wearing and tearing to account for a very big part.Usually structure of angular contact ball bearing retainer is a simple circle annular, circumferencial direction several pocket holes that evenly distribute, and rotor directly contacts with the pocket hole, and it is bigger to rub.In addition, in the bearing operation process, lubricant medium also is difficult to enter retainer inside and bearing element surface, normal appearance causes bearing owing to insufficient lubrication in actual use the premature failure, destruction.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can make things convenient for bearing lubrication, the bearing cage structure that reduces to rub.
For realizing above-mentioned technical purpose, technological scheme of the present invention is: a kind of bearing cage structure, comprise cage bar, retainer pocket hole, retainer pocket hole is arranged between the adjacent cage bar, on the cage bar in retainer pocket hole, along being provided with the projection that two ends contact with rolling element with the axial vertical direction of rolling element.
Described projection can be two sections, is separately positioned on the two ends of rolling element axial position.
The invention has the beneficial effects as follows: the projection that the present invention is provided with, make lubricant medium enter the rolling surface of bearing easily, improved lubrication effect; The two ends of projection contact with rolling element, have reduced the frictional force of rolling element, have also reduced the error that adds man-hour simultaneously.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the partial enlarged drawing of I portion among Fig. 1.
Fig. 3 is the structural representation of II portion among Fig. 1.
Fig. 4 be among Fig. 1 A-A to sectional view.
Embodiment
As shown in Figure 1, a kind of bearing cage structure comprises cage bar 2, retainer pocket hole 1, and retainer pocket hole 1 is arranged between the adjacent cage bar 2.
Shown in Fig. 2,3, on the cage bar 2 in retainer pocket hole 1, along being provided with the projection 4 that two ends contact with rolling element 3 with rolling element 3 axial vertical directions.
As shown in Figure 4, described projection 4 can be two sections, is separately positioned on the two ends of rolling element 3 axial positions.Be provided with like this, rolling element 3 just with two end in contact of projection 4, form 4 contacts, reduced frictional force.The space of lubricant medium is also formed on the bottom of projection 4, makes things convenient for lubricant medium to enter the rolling surface of bearing easily, has improved lubrication effect.
The foregoing description does not limit the present invention in any way, and every employing is equal to replaces or technological scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
Claims (2)
1. bearing cage structure, comprise cage bar (2), retainer pocket hole (1), retainer pocket hole (1) is arranged between the adjacent cage bar (2), it is characterized in that: on the cage bar (2) in retainer pocket hole (1), along being provided with the projection (4) that two ends contact with rolling element (3) with the axial vertical direction of rolling element (3).
2. bearing cage structure according to claim 1 is characterized in that: described projection (4) is arranged on the two ends of rolling element (3) axial position.
