The utility model provides a kind of improved bearing retainer and the bearing including the bearing retainer.
Illustrate the structure of bearing according to the present utility model with reference first to Fig. 2A to Fig. 2 C.
The bearing 100 of an embodiment according to the present utility model includes outer ring 101, inner ring 102, bearing retainer
It (in the following, sometimes referred to simply as " retainer ") 103 and is kept by retainer 103 and the rolling of raceway and inner ring 102 positioned at outer ring 101
Multiple rolling elements 104 between road.
The radial outside portion of retainer 103 is formed with multiple lubrication grooves.Lubrication groove is by the inner peripheral surface of outer ring 101 and holding
Gap between the peripheral surface 103O of the side circle of frame 103 is connected to the pocket hole P of retainer 103.Lubrication groove can improve axis
Hold 100 lubricating status.
More specifically, retainer 103 may include the first side circle 1031 and the second side circle 1032 and the first side of connection circle
1031 and the second side circle 1032 multiple crossbeams (not shown).It is formed in retainer 103 for accommodating and keeping rolling element 104
Pocket hole P.The radial outside portion of first side circle 1031 and the radial outside portion of the second side circle 1032 are respectively formed with multiple
Lubrication groove G1 and G2.One end of lubrication groove G1 is enclosed with the inner peripheral surface 101I of the rib of the axial side of outer ring 101 and the first side
Gap S1 connections between 1031 peripheral surface, the other end of lubrication groove G1 are connected to pocket hole P.Similarly, the one of lubrication groove G2
Gap S2 between the inner peripheral surface 101I and the peripheral surface of the second side circle 1032 of the rib of the axial other side of end and outer ring 101
Connection, the other end of lubrication groove G2 are connected to pocket hole P.
Preferably, can be that corresponding lubrication groove G1 and/or G2 is arranged in each pocket hole P.It is highly preferred that can be in each side
The lubrication groove G1 and G2 corresponding to each pocket hole P are both provided in circle 1031,1032.For example, being both provided with pair in each side is enclosed
In the case of a lubrication groove of each pocket hole P a lubrication groove G1 and one should be respectively present in the axial both sides of a pocket hole P
A lubrication groove G2.
Can be that a lubrication groove is arranged in each pocket hole P in an optional scheme.For example, circumferentially will be continuous
Can be the 1st, 3,5 ..., i.e. odd number pocket hole is arranged when the multiple pocket hole P being arranged are numbered with 1,2,3,4,5,6 ... respectively
Lubrication groove G1 is the 2nd, 4,6 ..., i.e. even number pocket hole setting lubrication groove G2.
With reference to Fig. 2A and Fig. 2 B, in one example, lubrication groove G1 includes collecting groove portion G11 and being connected to groove portion G12.It collects
The circumferential lengths of groove portion G11 are more than the circumferential lengths of connection groove portion G12.Collecting groove portion G11 makes gap S1 and is connected to groove portion G12
Connection.Connection groove portion G12 makes collection groove portion G11 be connected to pocket hole P.Preferably, a collection groove portion G11 is connected to groove portion with multiple
G12 is connected to.1031 complete cycle extension can be enclosed along the first side of retainer 103 by collecting groove portion G11.It is, of course, also possible to
The collection groove portion G11 for setting up multiple disconnections week of side circle 1031.Even if due in the position that connection groove portion G12 is not arranged
Fat can also be collected by setting, thus the setting for collecting groove portion G11 can effectively collect the fat in the S1 of gap, and the fat that will be collected into
It is transmitted to connection groove portion G12.
In one example, it is inside more than diameter can be formed as the width on the axial A of radially outer side portions by collection groove portion G11
The width of side.In other words, the axial cross section for collecting groove portion G11 is trapezoidal.This can more effectively collect the fat in the S1 of gap.
Connection groove portion G12 is formed as tilting relative to the radial R and axial direction A of bearing 1.Connection groove portion G12 is preferably kept away
It is formed in the first side circle 1031 with opening crossbeam.In this way, the bonding strength of crossbeam and the first side circle 1031 can not be lost.
With reference to Fig. 2 C, in one example, lubrication groove G1 does not include that groove portion G11 is collected shown in Fig. 2 B, to multiple profits
Gap S1 is connected to by sliding slot G1 with pocket hole P independently of one another.
The cross section that groove portion G12 and lubrication groove G1 shown in fig. 2 C is connected to shown in Fig. 2A with Fig. 2 B can be round, ellipse
Round or other shapes.
It should be appreciated that lubrication groove G2 shown in Fig. 2A can have similar with Fig. 2 B or shown in fig. 2 C lubrication grooves G1
Structure.
Illustrate effect and the effect of the lubrication groove of bearing according to the present utility model referring to Fig. 3 A and Fig. 3 B.
When bearing 100 works, especially when outer ring 101 is rotated relative to inner ring 102, fat 200 is due to centrifugal force
It acts on and accumulates in gap S1 and S2.In bearing 100 according to the present utility model, such as the dotted arrow in Fig. 3 A and Fig. 3 B
Shown, the fat 200 built up is squeezed and can return to pocket hole P by lubrication groove G1 and G2.Lubrication in retainer 103
Slot G1 and G2 provide fat channel, and the fat 200 accumulated in gap S1 and S2 is made to may return to pocket hole P, this realizes or promotes
The cycle of fat, it is ensured that fat can be reused.Finally bearing is made to have better lubricant effect, makes the service life of fat and bearing
It is elongated.
In the case where bearing 100 is applied to high-speed applications, the above-mentioned effect of the bearing of the utility model and effect are more
Significantly.
