Abstract
The utility model discloses a kind of self-sealing self-aligning roller bearings, are made of outer ring, inner ring, roller, retainer, sealing ring.Inner ring top is equipped with retainer, is equipped with roller on retainer, and roller top is outer ring, inner-ring small flange outer diameter be it is arc-shaped, two small rib outer diameter forms one using the bearing centre of gyration as the sphere in the center of circle;Sealing ring is circular ring shape, has bulge-structure on outer diameter, internal diameter is the sealing lip on an inclined-plane, and sealing ring is mounted between bearing outer ring and inner ring.Protrusion on sealing ring outer diameter is interference fitted with bearing outer ring alveolus, is fixed on sealing ring on bearing.Sealing ring sealing lip and the small rib edge spherical surface of bearing inner race are tangent, and the small rib of bearing inner race is remained with sealing ring sealing lip in bearing aligning and contacted, and guarantee the aligning effect with certain angle when bearing aligning.The utility model self-sealing self-aligning roller bearing can preferably meet the operating condition of bearing long-term work, have the effect of long-life, high reliability, non-maintaining bearing.
Description
Technical field
The present invention relates to a kind of self-aligning roller bearings, are specifically related to a kind of aligning roller axis with self sealing structure
It holds.
Background technique
Often the axial line of outer ring and the axial line of inner assembly are not parallel when due to self-aligning roller bearing work, therefore it is required that
Bearing has certain aligning angle, and conventional bearings sealing structure is that sealing ring is embedded on fixed non-rotary part, usually
For outer ring, sealing lip contacts rotating part, and this structure can be generated in bearing aligning between sealing ring and the inner ring of rotation
Larger gap can not play sealing function, so conventional self-aligning roller bearing itself is without sealing device.Open form bearing needs fixed
Phase grease up is unable to reach the long-term non-maintaining requirement of oil-field oil pumper.
Existing self-aligning roller bearing, to solve to seal problem, usually additional two seal receptacles, sealing ring are mounted in sealing
On seat, sealing lip contact bearing inner ring end face both increases part, also changes the installation dimension of bearing, simultaneously because sealing
The influence of seat, the aligning angle that will lead to bearing reduce, and influence aligning effect, and bearing the inside and outside circle axial line of bearing not
Gap can be still generated when parallel, sealing effect is bad.
Summary of the invention
The object of the present invention is to provide one kind can be with the self-aligning roller bearing of self-sealing, without increasing seal receptacle, structure letter
Single reliable, aligning performance is excellent.
To achieve the purpose of the present invention, the technical solutions adopted are as follows.
A kind of self-sealing self-aligning roller bearing, is made of outer ring, inner ring, roller, retainer, sealing ring.On the inner ring
Portion is equipped with retainer, is equipped with roller on retainer, and roller top is outer ring, the inner-ring small flange outer diameter be it is arc-shaped, two
A small rib outer diameter forms one using the bearing centre of gyration as the sphere in the center of circle;The sealing ring is circular ring shape, structure one
Ring skeleton has bulge-structure on ring skeleton outer diameter, and internal diameter is the sealing lip on an inclined-plane, and the sealing ring is mounted on axis
Between bearing outer-ring and inner ring.
The sealing ring is rubber material.
Protrusion on the sealing ring outer diameter is interference fitted with bearing outer ring alveolus, and sealing ring is made to pass through bearing outer ring alveolus
It is fixed on bearing.
The sealing ring sealing lip and the small rib edge spherical surface of bearing inner race are tangent, and the small rib of bearing inner race is in bearing aligning
When remain and contact with sealing ring sealing lip, while guaranteeing sealing, guarantee the tune with certain angle when bearing aligning
Heart effect.
Sealing ring sealing lip plays certain sealing and aligning with revolution in the small rib work of bearing inner race and makees in the present invention
With.Self-sealing self-aligning roller bearing of the invention can preferably meet the operating condition of bearing long-term work, which is guaranteeing to adjust
While heart roller bearing works normally characteristic, have the effect of long-life, high reliability, non-maintaining bearing.

Specific embodiment
In conjunction with attached drawing, the present invention will be described.
A kind of self-sealing self-aligning roller bearing is made of outer ring 1, inner ring 3, roller 2, retainer 9, sealing ring 4.In described
It encloses 3 tops and is equipped with retainer 9, roller 2 is installed on retainer 9,2 top of roller is outer ring 1,10 outer diameter of inner-ring small flange
To be arc-shaped, two small rib outer diameter forms one using the bearing centre of gyration as the sphere in the center of circle;The sealing ring 4 is annulus
Shape, structure is a ring skeleton 5, has raised 7 structures on ring skeleton outer diameter, and internal diameter is the sealing lip 6 on an inclined-plane, institute
Sealing ring 4 is stated to be mounted between bearing outer ring 1 and inner ring 3.
Sealing ring 4 uses nitrile rubber material.
Protrusion 7 and bearing outer ring alveolus 8 on 4 outer diameter of sealing ring are interference fitted, and sealing ring is made to pass through bearing outer ring alveolus
It is fixed on bearing.
Sealing ring sealing lip 6 and the small 10 edge spherical surface of rib of bearing inner race are tangent, and the small rib 10 of bearing inner race is in bearing tune
It remains and contacts with sealing ring sealing lip when the heart.
