Abstract
A rod end knuckle bearing includes a rod end body and a centripetal oscillating bearing. A seal sleeve covers the rod end oscillating bearing; a seal ring with skeleton is inside the rod end oscillating bearing; the outer surface of the centripetal oscillating bearing inner ring has blind holes where solid self-lubricating materials are embed. Thus the combination of the seal sleeve and the seal ring with skeleton can prevent the inlet of feculence, oil, water, etc. effectively to performe a double protection and a self-lubricating; the abrasion of the working surface of the rod end is reduced and the using lifetime of the rod end oscillating bearing is improved.
Description
Technical field:
The utility model relates to a kind of spherical plain bearing rod end, specifically, relates to a kind of spherical plain bearing rod end with protective gear selflubricating.
Background technique:
Existing spherical plain bearing rod end is made up of rod end body, plain radial bearing; also there is not special protective gear that the working surface of rod end body bulb position and plain radial bearing is carried out integral protection; cause present spherical plain bearing rod end; particularly the spherical plain bearing rod end of heavy truck is not long working life; and safeguard oily, operation inconvenience.
Summary of the invention:
In order to overcome above shortcoming, the utility model provides a kind of selflubricating spherical plain bearing rod end that the working surface of rod end body bulb position and plain radial bearing is carried out integral protection that has.
In order to achieve the above object, the technological scheme that the utility model provides is that spherical plain bearing rod end is made up of the rod end body, the plain radial bearing that have a hole.Externally,, become the tube that stretches out that surface of contact is arranged, be provided with stepped slot stretching out tube outer surface plain radial bearing inner ring two ends lengthenings.Seal closure with three openings is sleeved on rod end body bulb position, and two openings of seal closure just are enclosed within the inner ring two ends and stretch out in the stepped slot of tube, and another opening just is placed on the rod end body rod; In inside, be contained in the seal ring of the seal ring of plain radial bearing inside for the band skeleton.Forming plain radial bearing inside like this has seal ring to stop dust etc. to enter, and the outside has seal closure can stop the intrusion of all dirts, oil, water etc., thereby the working surface of rod end body bulb position and plain radial bearing is carried out integral protection.
Leave blind hole at radial bearing inner ring outer surface, inlay solid self lubricant material in the blind hole, make the spherical plain bearing rod end at work needn't lubricating oil filling, easy to maintenance.
The beneficial effects of the utility model: the band backbone sealing ring is stable better than conventional seals circle; can effectively stop dust etc. to enter; seal closure and the combination of band backbone sealing ring; can effectively stop the intrusion of all dirts, oil, water etc.; play double protection; but selflubricating again, thereby the wearing and tearing of minimizing spherical plain bearing rod end working surface, the working life of improving spherical plain bearing rod end.
Description of drawings
Fig. 1 is the structure sectional view of the utility model spherical plain bearing rod end;
Fig. 2 is the left view of the utility model spherical plain bearing rod end;
Fig. 3 is the structure sectional view of seal closure.
1 is the rod end body among the figure, the 2nd, and plain radial bearing, the 3rd, seal closure, the 4th, plain radial bearing outer ring, the 5th, the plain radial bearing inner ring, 51 lengthening inner rings stretch out tube, the 6th, the band backbone sealing ring, the 7th, the stepped slot of inner ring, the 81,82, the 83rd, seal closure opening, the 9th, blind hole.
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, spherical plain bearing rod end is made up of the rod end body (1) that has a hole, plain radial bearing (2), plain radial bearing (2) inner ring (5) two ends lengthenings, become surface of contact arranged stretch out tube (51), be provided with stepped slot (7) stretching out tube (a 51) outer surface.As Fig. 3, seal closure with three openings (3) is sleeved on rod end body bulb position by rod end body (1), two openings (81,82) of seal closure (3) just tightly are enclosed within the inner ring two ends and stretch out in the stepped slot of tube, and another opening (83) just is placed on rod end body rod portion top.Leave blind hole (9) at radial bearing inner ring outer surface, blind hole is inlayed solid self lubricant material in (9).The seal ring (6) of band skeleton is housed in plain radial bearing (2) inside like this; a seal closure of outer suit (3); seal ring (6) protection is arranged in just becoming on the whole; seal closure (3) protection is arranged outward; thereby the working surface that reaches rod end body bulb position and plain radial bearing (2) carries out integral protection; again can selflubricating, thus the working life of improving spherical plain bearing rod end.
Claims (5)
1. a spherical plain bearing rod end is made up of rod end body, plain radial bearing, it is characterized in that: the seal closure (3) of three openings is equipped with the top in spherical plain bearing rod end bar portion.
2. a kind of spherical plain bearing rod end as claimed in claim 1 is characterized in that: plain radial bearing inner ring (5) two ends add to grow up to stretches out tube (51), is provided with stepped slot (7) stretching out tube.
3. a kind of spherical plain bearing rod end as claimed in claim 1, it is characterized in that: two openings (81,82) of seal closure (3) are set in plain radial bearing inner ring two ends and stretch out in the stepped slot (7) of tube, and an opening (83) is sleeved on the bar of rod end body.
4. a kind of spherical plain bearing rod end as claimed in claim 1 is characterized in that: plain radial bearing inner ring outer surface leaves blind hole (9), is inlaid with solid self lubricant material in the blind hole.
5. a kind of spherical plain bearing rod end as claimed in claim 1 is characterized in that: the seal ring of plain radial bearing is band backbone sealing ring (6).
