It is proposed in the above background technology to solve it is an object of the invention to provide a kind of sliding bearing of high-efficiency lubricating
Problem.
To achieve the above object, the present invention provides following technical solution：A kind of sliding bearing of high-efficiency lubricating, including it is outer
Circle, bearing shell, fix axle journal, flexible axle journal and inner ring, and fuel feed hole is fixedly installed on the outer ring, is fixed on the outer ring inner wall
One layer of bearing shell is provided with, supporting rod is fixedly installed on the fixed axle journal and flexible axle journal, the fixed axle journal passes through branch
Strut is movably arranged on the inner side of outer ring, and the flexible axle journal is movably arranged on the inner side of fixed axle journal, on the flexible axle journal
Be fixedly installed spring, the fixed axle journal and it is flexible between on be fixedly installed and limit hole, the inner ring passes through supporting rod
Distance is limited with flexible axle journal, mounting hole is fixedly installed on the inner ring.
Preferably, ball is installed with the restriction hole on the fixed axle journal and flexible axle journal, and is limited in hole
Cushion is provided with, reduces ball and limits the friction between hole.
Preferably, be fixedly uniformly arranged with multigroup spring on the flexible axle journal, multigroup and symmetrical design prevent because
Be pressurized the excessive damage for causing axle journal.
Preferably, it is fixedly installed multigroup supporting rod on the inside of the bearing shell and inner ring.
Preferably, multigroup mounting hole is fixedly installed on the inner ring, the fuel feed hole set on the outer ring is rectangle.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the present invention between outer ring and inner ring by setting two layers of axle journal, and axle journal passes through supporting rod and outer ring and inner ring
Between be provided with buffer distance, reduce friction during operating, effectively extend the service life of bearing.
2nd, the present invention limits and is provided with circular ball on hole, and cylindrical design had both reduced rubbing when operating between ball
Wipe, and will not be produced between outer ring and inner ring and contact friction, simple in structure, using effect is good.

Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
- 2 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of sliding bearing of high-efficiency lubricating, including outer ring 1,
Bearing shell 11, fixed axle journal 4, stretch axle journal 6 and inner ring 8, and fuel feed hole 10,1 inner wall of outer ring are fixedly installed on the outer ring 1
On be fixedly installed one layer of bearing shell 11, be fixedly installed supporting rod 9, the fixation on the fixed axle journal 4 and flexible axle journal 6
Axle journal 4 is movably arranged on the inner side of outer ring 1 by supporting rod 9, and the flexible axle journal 6 is movably arranged on the inner side of fixed axle journal 4,
Spring 7 is fixedly installed on the flexible axle journal 6, between the fixed axle journal 4 and flexible axle journal 6 on be fixedly installed restriction
Hole 3, the inner ring 8 limit distance by supporting rod 9 and flexible axle journal 6, mounting hole 5 are fixedly installed on the inner ring 8.
Ball 2 is installed with restriction hole 3 on the fixed axle journal 4 and flexible axle journal 6, and limits and is set in hole 3
Cushion is equipped with, reduces ball 2 and limits the friction between hole 3；Multigroup spring 7 is fixedly installed on the flexible axle journal 6, it is more
Group and symmetrical design are prevented because being pressurized the excessive damage for causing axle journal；The inner side of the bearing shell and inner ring 8 is fixedly installed
