Embodiment
The needle bearing 11 of one embodiment of the present invention is described with reference to figure 4A～Fig. 6 C.
Shown in Fig. 4 A and Fig. 4 B, needle bearing 11 possesses: outer ring 13, and it has two cycle components 12 being cut apart by the cutting lines that extends on the axial direction of bearing; A plurality of needle-like rollers 14, its rolling is configured on the roller surface of outer ring 13 freely; Guard ring 15 with the interval that keeps needle-like roller 14.
In addition, shown in Fig. 5 B and Fig. 5 C, a side end of the circumferencial direction of cycle component 12 is convex forms, and end side is a concave shape, by the concavo-convex of two cycle components 12 combined, forms outer ring 13 cylindraceous.At this, if the cutting lines of outer ring 13 outer ring 13 can be cut apart in a circumferential direction, even with axially not strict conformance also can.
The needle bearing 11 of said structure is because the part of outer ring 13 and guard ring 15 is cut off, so can be with the bearing of doing the position that can't be pressed in the axial direction of crankshaft, camshaft and the pitman arm shaft etc. of automobile is supported.
In addition,, prevent outer ring 13 on cycle component 12, and, can limit guard ring 15 to axial moving by engaging pawl 12b is set to the circumferencial direction rotation by projection 12a is set.
At this, on cycle component 12, being provided with at its circumferencial direction central part becomes the zone line of load area 12d when bearing uses, being provided with at its circumferencial direction two end part becomes the end regions in unsupported zone 12e when bearing uses, projection 12a and engaging pawl 12b are positioned at the end regions 12e of opposition side across zone line 12d.
For example, be processed to form by plunging under the situation of projection 12a in aperture surface one side from cycle component 12, form recess and can not become even surface on roller surface, the action by the needle-like roller on the recess becomes unstable.In addition, the snap portions of guard ring 15 might hang over the side of engaging pawl 12b.Therefore,, then become the obstruction bearing reason of rotation smoothly of the malrotation etc. of needle-like roller, might cause fault if projection 12a or engaging pawl 12b are positioned at load area.
Therefore, by projection 12a and engaging pawl 12b are disposed at the end regions that becomes unsupported zone, can avoid these faults.In addition, though projection 12a and engaging pawl 12b can be formed at the end regions of same side,, make respectively projection 12a, the processing that engages pawl 12b and cycle component 12 are become easy by be configured in the end regions 12e of opposition side across zone line 12d.
And, constituting under the situation of outer ring 13 by two cycle components 12, be that the central angle of benchmark is Φ if establish circumferencial direction outermost end 12c with cycle component 12, then end regions 12e is in the scope of 5 °≤Φ≤45 °.

In the above-described embodiment, show outer ring 13 by the example that is constituted by two cycle components of cutting apart 12 diametrically, but be not limited thereto, being divided into any number can.
In the above-described embodiment, show the example that ground, one place, a place disposes projection 12a and engages pawl 12b on each cycle component 12, but be not limited thereto, also can also can be configured in the many places of each cycle component 12 only in place configuration on the full week of outer ring 13.
In addition, in the above-described embodiment, show the example that engaging pawl 12b is set on the part of the axial end portion of cycle component 12, but engaging pawl 12b also can be set in the whole zone of the axial end portion of cycle component 12.In this case, owing to do not have guard ring 15 to hang over the worry of the side of engaging pawl 12b, so can not produce problems such as malrotation even engaging pawl 12b is positioned at load area yet.
And guard ring 15 can be not limited to resin and by formation such as punch process metallic material, also can be total bearing of not wanting guard ring 15.
As preferred implementation, utilize Fig. 7 A～conduct that Figure 10 explanation forms on cycle component 12 to locate the preferred size of the projection 12a of engagement portion.
The projection 12a that on cycle component 12, forms, owing to for example be processed to form by plunging, so portion has the hole 12c that runs through aperture surface from outer diametric plane in the central.If this hole 12c is excessive, then the action by the needle-like roller 14 on the 12c of hole becomes unstable, becomes the reason of vibration and noise, and has the worry of the early damage that causes needle bearing 11.
Therefore, shown in Fig. 7 A and Fig. 7 B, with the diameter d of hole 12c
1Effective length t with needle-like roller 14

1In＜0.5 the scope.Thus, which position pore 12c is not positioned at, the effective length of needle-like roller 14 be in the state that the roller surface with outer ring 13 joins more than 50%, therefore can make by the action of the needle-like roller 14 on the 12c of hole stable.Consequently, can obtain to keep the needle bearing 11 of rotation of the slyness of needle-like roller 14.
And, in the above-described embodiment, show the diameter d of hole 12c
1Than the big example of the roller diameter of needle-like roller 14, but be not limited thereto, shown in Fig. 8 A and Fig. 8 B, even in the diameter d of hole 22c
2Under the little situation of the roller diameter of needle-like roller 24, by satisfying d
2/ t
2＜0.5, just can expect same effect.
And then hole 12c, 22c there is no need to be positioned at the central authorities of the roller length of needle- like roller 14,24, shown in Fig. 9 A and Fig. 9 B, can also be configured in the position of departing from from the central authorities of roller length.
But hole 12c, 22c are if be configured in the position that overlaps with end 14a, the 24a of needle- like roller 14,24, and be even then hole 12c, 22c are little, also unstable by the action of the needle-like roller on hole 12c, the 22c 14,24.Therefore, hole 12c, 22c just can eliminate the problems referred to above by being configured in not and the end 14a of needle-like roller, the position that 24a overlaps.
And then, as shown in figure 10, the diameter d of hole 12c
1Be set at the inside diameter D of cycle component 12 and satisfy d
1The scope of＜D＜0.2.If surpass this scope, it is excessive that then hole 12c is equivalent to the ratio of internal diameter of cycle component 12, become the reason of vibration and noise, and existence causes the misgivings of the early damage of needle bearing 11.
Then,, carried out following test, the hole of prescribed level has been set in the outer ring of needle bearing, under the state that has applied radial load, made its rotation, measured the bearing life of this moment in order to confirm effect of the present invention.Test conditions is as follows.In addition, test result is as shown in table 1.
The diameter in hole: φ 3, φ 5, φ 6 (mm)
Radial load: 5000 (N)
Rotating speed: 3000 (rpm)
[table 1]
The diameter in table 1. hole and the relation of bearing life
Table 1 is that expression is that life-span of test result of benchmark is than (L with the non-proous bearing
50) table.In view of the above, under the situation below 50% of the effective length of needle-like roller, do not find the decline of bearing life at the diameter in hole.In addition, in the situation of the central authorities that the hole are configured in roller length be configured under the locational situation that departs from from central authorities, test respectively, test result is not found difference.Thus, confirmed effect of the present invention.
With reference to figure 11A～Figure 12, other mode of executions of the present invention are described.The needle bearing 11 of said structure uses mostly under the high capacity environment, therefore, and to the also demanding intensity of the 12a of locator protrusions portion.Therefore, in a preferred embodiment, the 12a of locator protrusions portion has roof 12c at front end shown in Figure 11 A.Thus, the sufficient intensity in the time of can guaranteeing under the high capacity environment, to use.
In addition, as other mode of execution, shown in Figure 11 B, can also on the roof 22c of the 22a of locator protrusions portion, have oilhole 22d.Thus, can therefore can obtain the superior needle bearing of lubricity to the rolling surface of needle-like roller supplying lubricating oil effectively.
And then, as the additive method of guaranteeing intensity, as shown in figure 12, can also set a jut 32a long elliptical shape on the circumferencial direction of cycle component 32 the cross section, be a＜b.The torque that the rolling friction that is produced by 14 rotations of needle-like roller causes imposes on cycle component 32 in a circumferential direction.Therefore, the action direction that is made as with load by the cross section with the 32a of locator protrusions portion is the elliptical shape of major axis, just can improve the intensity of the 32a of locator protrusions portion.At this moment, because enough intensity can guarantee under the high capacity environment to use the time so the front end of the 32a of locator protrusions portion can be an opening end, also can have roof.
