Film is eager to excel than the bearing capacity of heavy oil film, and wherein the bearing capacity of oil film is also directly proportional with the dynamic viscosity of lubricating oil, most
Also it is directly proportional to the relative velocity between two slidingsurfaces under number service condition, and in the case where top load is operated, oil film is thick
Degree is very low, loses the ability of bearing load, and axle weares and teares with bushing.Therefore sliding bearing application scenario is general low
Under the working condition of speed, underloading or intermittent work.But under some special screnes, axle can occur bending phenomenon, work as flexure
Can cause badly damaged to sliding bearing mechanical structure when spending larger, or even the structure of bearing body is caused to damage.The present invention is main
If the characteristics of designing a kind of shaft deflection conjugation compensation sliding bearing mechanism, this Bearning mechanism is, when axle bends, axle
Holding mechanism within the specific limits can be freely movable, is always ensured that the concentricity of axle and Bearning mechanism, greatly reduces bearing machine
Radial direction torque suffered by structure and bearing body, and the Bearning mechanism simple structure, it is easy to install, it is easy-maintaining.
The content of the invention
It is an object of the present invention to provide a kind of shaft deflection conjugation compensation sliding bearing mechanism, its operation principle be Bearning mechanism with
The outer surface of bearing body contact is arc surface of revolution, and the shaft centre line of Bearning mechanism can be freely movable within the specific limits, and
Remain concentric with the axle for bending.Because the friction between arc surface of revolution and bearing contact level is small, and bearing
Mechanism does not receive radial direction torque in itself, so greatly strengthen the reliability of Bearning mechanism.
Realizing the technical scheme that above-mentioned purpose is used is：
A kind of shaft deflection conjugation compensation sliding bearing mechanism of the present invention, mainly by axle sleeve inner ring (1), conjugation bearing
Set (2), sliding bearing one (3), sliding bearing two (4), the part of outer ring (6) five composition, wherein conjugation bearing holder (housing, cover) (2) is opened in being
Formula, by upper bearing sleeve (8) and lower bearing sleeve (9), two parts are constituted up and down, are conjugated bearing holder (housing, cover) (2) and bearing body (5) interference fits,
The outer surface of conjugation bearing holder (housing, cover) (2) is arc evagination surface of revolution (b), and it is arc that the inner surface of bearing body (5) has one section of curved surface
Indent surface of revolution (d), when bending occurs in axle, axle can drive shaft deflection to be conjugated compensation sliding bearing and be contacted in bearing body (5)
Freely rotated up and down within the specific limits on face, the flexure that compensation axle is produced, Bearning mechanism is kept good with axle (7)
Axis concentricity, and Bearning mechanism can be made not receive radial direction moment loading in itself.Conjugation bearing holder (housing, cover) (2) upper bearing sleeve (8) and under
The contact surface of bearing holder (housing, cover) (9) is the structure type (a) of groove insertion, it is ensured that upper bearing sleeve (8) and lower bearing sleeve (9) will not phases
To movement, and conjugation bearing holder (housing, cover) (2) two ends are gland integrative-structure form (c), by gland integrative-structure form (c) at two ends
Axle sleeve inner ring (1), outer ring (6), sliding bearing one (3), sliding bearing two (4) are positioned at conjugation bearing holder (housing, cover) (2) internal.Axle sleeve
Inner ring (1) and outer ring (6) be between wide arc gap coordinate, between axle sleeve inner ring (1) and axle (7) be gap cooperation, outer ring (6) together
Yoke axle bearing sleeve (2) inner surface is interference fits, and the wherein two ends of bearing inner race (1) are curved end, can position sliding bearing one
(3) distance of inner ring and the inner ring of sliding bearing two (4).
This method for designing is mainly characterized by, it is ensured that when axle bends, and Bearning mechanism does not receive radial load with bearing body
Square is acted on, and greatly increased the reliability of Bearning mechanism and bearing body.
The present invention is on probation through user, and reaction effect is good.
