Description
Technical field
The utility model is related to a kind of self-aligning roller bearing.
Background technology
Self-aligning roller bearing can bear heavy load and shock loading, and the lubrication for self-aligning roller bearing is important, profit
If lubricating oil fat charge is excessive, the friction torque of bearing is bigger, is easily caused bearing heating, reduces the life-span of bearing, lubricating oil
Fat is too small, can also reduce the operating efficiency of bearing, can also reduce the life-span, often can also reduce work effect to bearing filling lubricating oil
Rate.
The content of the invention
To solve the above problems, the utility model provides a kind of self-aligning roller bearing, and simple structure reduces adding for lubricating oil
Plus frequency, operating efficiency is improved, increase the service life.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of self-aligning roller bearing, including bearing outer ring and bearing inner race, are provided between bearing outer ring and bearing inner race
Retainer, is provided with biserial roller on retainer, and the inner surface of bearing outer ring is sphere, inner surface and the roller of bearing outer ring
Surface is engaged, and the outer surface of bearing inner race is provided with biserial roller track, and the surface of roller track is engaged with the surface of roller,
It is trapezoidal baffle ring that section is provided between biserial roller, and retainer is butted on the outside of baffle ring, is butted in bearing on the inside of baffle ring
The outside of circle, distinguishes the annular groove of radially at least uniform three arcuations, in bearing outer ring on the axial both sides end face of baffle ring
Sealing ring axially is respectively provided on two sides with, the both sides end face of bearing inner race is butted on two inner sides of sealing ring respectively.
The utility model simple structure, reduces the addition frequency of lubricating oil, improves operating efficiency, increases the service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the mplifying structure schematic diagram of the A in Fig. 1.
Wherein：Bearing outer ring 1, bearing inner race 2, roller track 2-1, retainer 3, roller 4, baffle ring 5, annular groove 5-1, sealing
Ring 6.
Specific embodiment
It is described in further detail below in conjunction with the most preferred embodiment shown in accompanying drawing：
As shown in Fig. 1~Fig. 2, a kind of self-aligning roller bearing, including bearing outer ring 1 and bearing inner race 2, in bearing outer ring 1
Retainer 3 is provided with and bearing inner race 2 between, biserial roller 4 is provided with retainer 3, the inner surface of bearing outer ring 1 is sphere,
The inner surface of bearing outer ring 1 is engaged with the surface of roller 4, and the outer surface of bearing inner race 2 is provided with biserial roller track 2-1, rolling
The surface of sub-track 2-1 is engaged with the surface of roller 4, and it is trapezoidal baffle ring 5, baffle ring 5 that section is provided between biserial roller 4
Outside be butted on retainer 3, the inner side of baffle ring 5 is butted on the outside of bearing inner race 2, on the axial both sides end face of baffle ring 5 respectively
The annular groove 5-1 of radially uniform five arcuations, sealing ring 6 is respectively provided on two sides with the axial direction of bearing outer ring 1, bearing inner race 2
Both sides end face is butted on two inner sides of sealing ring 6 respectively.
The utility model when in use, is pacified by being added between bearing outer ring 1 and bearing inner race 2 after appropriate lubricating oil
Sealing ring 6 is installed, parts of lubricating oil can be stored in annular groove 5-1, after bearing working is lost lubricating oil for a period of time, storage
Lubricating oil can in time supplement the lubricating oil of Bearing inner so that bearing can work long hours, and reduce the addition frequency of lubricating oil,
Operating efficiency is improved, is increased the service life.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
