Description
Technical field
It the utility model is related to oscillating bearing technical field, more particularly to a kind of pass with the micro- texture of surface crosswise reticulate pattern
Bearings.
Background technology
Oscillating bearing is a kind of sliding bearing, and it is by the outer ring group of an inner ring with spherical outside surface and one with Internal Spherical Surface
Into being mainly used in that concentricity requirement is not high, working surface pressure is larger and makees to swing at a slow speed or the supporting portion of gyration.
When oscillating bearing works, this does relative slip to friction pair with inside and outside circle, how effectively to reduce friction, mitigates abrasion, is to extend
The determinant of oscillating bearing service life.
Current commonplace way is to design some lubrication systems, such as circumferencial direction on the inside and outside circle surface of oscillating bearing
Oil-way, the oil-way of axial direction, spiral and embossing formula oil-way etc..These ways can strengthen to a certain extent
The greasy property of oscillating bearing, but because the covering surface of oil-way is smaller, to oscillating bearing Internal and external cycle working surface institute
The lubrication risen is still limited.
The Chinese invention patent of Patent No. 201410023303.5 disclosed a kind of oscillating bearing on January 17th, 2014,
It has the inner ring of spherical outside surface, the outer ring being set on inner ring, and outer ring has the Internal Spherical Surface that the spherical outside surface with inner ring is slidably matched
And the annular end face of Internal Spherical Surface both sides is axially located in, annular end face is provided with groove.But this oscillating bearing, only set recessed
Groove adds lubricant, it is impossible to avoids oscillating bearing that abrasive wear occurs well, life-span of oscillating bearing can not obtain very big
Improve.

Preferably, the spacing degree close to the adjacent bar groove of the second annular lubricant groove is less than away from second ring
The spacing of the adjacent bar groove of shape lubrication groove.Close to the second annular lubricant groove bar shaped separation it is small, transporting velocity faster, then by
Walk toward remotely conveying, the lubricant so injected can be spread apart in time, and lubricant effect is more preferable.
Preferably, first lubricant through hole and the second lubricant through hole are elastic through hole, when adding lubricant,
Lubricant can be added from elastic through hole, after addition terminates, elastic through hole closes automatically.In use, lubricant can just be prevented
Overflowed from the first lubricant through hole and the second lubricant through hole.
Released preferably, being equipped with absorption in each first annular lubrication groove and each second annular lubricant groove
Layer is put, when lubricant adds excessive, absorption releasing layer can adsorb unnecessary lubricant, when lubricant starvation, just can release
Put the lubricant of absorption.The probability for causing oscillating bearing service life to be cut short because forgetting addition lubricant can so be reduced.
Preferably, first lubricant through hole and second lubricant through hole have four, and circumferential angle is
It 90 degree, so can be uniformly distributed the lubricant of addition, and be easy to add lubricant.
Preferably, the spherical curved internal surface sets the micro- texture of overlapping curve, so do, be better able to increase profit
It is sliding, minute abrasive is absorbed, avoids oscillating bearing that abrasive wear occurs, increases service life.
Preferably, the pore density close to the first lubricant through hole is more than the density away from the first lubricant through hole, lean on
The pore density of nearly second lubricant through hole is more than the density away from the second lubricant through hole.Accelerate what is entered from lubricant through hole
The diffusion of lubricant.
Preferably, being provided with frosted layer in each bar-shaped trough, after lubricant is added, frosted layer reduces lubricant stream
Dynamic speed, can so be such that lubricant is more uniformly distributed.
By implementing above-mentioned technical proposal, have the advantages that：The utility model by setting the micro- texture of overlapping curve,
And first annular lubrication groove, the second annular lubricant groove, the first lubricant through hole, the second lubricant through hole are improved, can be with
Improve oscillating bearing greasy property, increase the effect in oscillating bearing life-span, and the spilling for reducing lubricant wastes.
