Abstract
A kind of centripetal self-aligning roller bearing of novel full rolling element, it is related to a kind of rolling bearing, for the present invention to solve existing self-aligning roller bearing under conditions of high-speed overload, there is the problem of inordinate wear fracture, roller is peeled off with the inordinate wear of inner ring guide ring, inner ring raceway in retainer pocket hole.The present invention includes outer ring, inner ring and roller, the outer surface of outer ring and the inner surface of inner ring are cylindrical surface, the inner surface of outer ring is equipped with and the matched concave spherical surface raceway of roller, the circumference of the outer surface of inner ring is equipped with and the matched raceway of roller, outer ring is sleeved on inner ring, roller is filled between outer ring and inner ring, the both ends of the surface of the inner ring are respectively provided with a filling slot.The present invention avoids the inordinate wear fracture of retainer pocket hole without retainer, and roller occurs with the phenomenon that inner ring guide ring inordinate wear.The present invention is suitable for heavy duty or oscillating load but the occasion that cannot bear axial load.
Description
Technical field
The present invention relates to a kind of roller bearings, and in particular to a kind of centripetal self-aligning roller bearing of novel full rolling element.
Background technology
Current domestic conventional use of self-aligning roller bearing is biserial symmetrical expression self-aligning roller bearing, by outer ring, inner ring, guarantor
Hold frame, rolling element composition.Inner ring is symmetrical structure, and band guide ring separates two row rollers, is often used in low-speed heave-load operating mode
Under.
With the development of the times, bearing applying working condition condition is more and more severe, and bearing rotating speed higher bears load bigger,
It is different that this results in the self-aligning roller bearing of previous structure that the inordinate wear fracture of retainer pocket hole, roller and inner ring guide ring often occurs
The phenomena of the failure such as often abrasion, inner ring raceway peeling, the operation of severe machine.
Invention content
In order to solve existing self-aligning roller bearing under conditions of high-speed overload, retainer pocket hole abnormal the present invention occurs
The problem of wear and rupture, roller is peeled off with the baffle ring inordinate wear in inner ring, inner ring raceway, and a kind of novel full rolling element is provided
Centripetal self-aligning roller bearing.
The present invention adopts the technical scheme that solve above-mentioned technical problem：
It includes outer ring, inner ring and roller,
The outer surface of outer ring and the inner surface of inner ring are cylindrical surface, and the inner surface of outer ring is equipped with and the matched recessed ball of roller
Face raceway, the circumference of the outer surface of inner ring, which is equipped with, to be sleeved on the matched raceway of roller, outer ring on inner ring, outer ring and inner ring it
Between filled roller, the both ends of the surface of the inner ring are respectively provided with a filling slot.
The present invention has the advantages that compared with prior art：
One, the present invention without baffle ring, bearing without in retainer and inner ring due in use, avoiding retainer pocket
Hole inordinate wear fracture, roller occur with the phenomenon that inner ring guide ring inordinate wear.
Two, the present invention expires rolling element structure due to being single-row centripetal, and overall width is the one of former double-row self-aligning roller bearing
Half, two sets of uses can be installed simultaneously, bearing capacity improves 44.42%.
Description of the drawings
Fig. 1 is the overall structure figure of the present invention；
Fig. 2 is the A-A sectional views of Fig. 1.
Specific implementation mode
Specific implementation mode one：Illustrate present embodiment in conjunction with Fig. 1 and Fig. 2, present embodiment it include outer ring 1, it is interior
Circle 2 and roller 3,
The outer surface of outer ring 1 and the inner surface of inner ring 2 are cylindrical surface, and the inner surface of outer ring 1 is equipped with matched with roller 3
Concave spherical surface raceway, the circumference of the outer surface of inner ring 2, which is equipped with, to be sleeved on 3 matched raceway of roller, outer ring 1 on inner ring 2, outer ring
Roller 3 is filled between 1 and inner ring 2, the both ends of the surface of the inner ring 2 are respectively provided with a filling slot 2-1.
The cooperation of concave spherical surface raceway and roller 3 is set it is the deflection in order to enable outer ring 1 to generate with respect to inner ring 2 certain angle.
Specific implementation mode two：Illustrate present embodiment, the described two dress segments of present embodiment in conjunction with Fig. 1 and Fig. 2
Circumferentially spaced about 180 ° arrangements of the mouth 2-1 in inner ring 2.
Present embodiment is convenient for the installation of roller 3.
Other compositions and connection relation are same as the specific embodiment one.
Specific implementation mode three：Illustrate present embodiment in conjunction with Fig. 1 and Fig. 2, the rolling on inner ring 2 described in present embodiment
The section in road is arch or U-shaped.So set, the bottom surface portions of raceway on inner ring 2 be with roller side it is matched within
The midpoint of the central shaft of circle 2 is the convex spherical raceway of the centre of sphere, has aligning function.
Other compositions and connection relation are identical with embodiment two.
Present embodiment, which makes roller 3 be rolled in the raceway of inner ring 2, makes roller 3 not skid off.
Specific implementation mode four：Illustrate present embodiment in conjunction with Fig. 1 and Fig. 2, concave spherical surface raceway described in present embodiment
The centre of sphere of concave spherical surface overlapped with the midpoint of the central shaft of inner ring 2.So set, concave spherical surface raceway has self-aligning function.
Other compositions and connection relation are the same as the specific implementation mode 3.
Specific implementation mode five：Illustrate present embodiment in conjunction with Fig. 1 and Fig. 2, the side of roller 3 described in present embodiment
For convex spherical.The side of roller is to rotate the curved surface formed by any one contour line.The concave spherical surface of present embodiment and outer ring 1
Raceway cooperation can make outer ring 1 deflect certain angle around the central point of inner ring 2.
Other compositions and connection relation are identical as specific implementation mode one, two, three or four.
