Abstract
The utility model relates to a bearing technology field, more specifically says, relates to heavily loaded for hoist outer three row tooth -like cylindrical roller slewing bearing. The utility model discloses outer three row tooth -like cylindrical roller slewing bearing includes first inner circle, first sealing washer, second sealing washer, first isolating ring, outer ring gear, first roller, second roller, second isolating ring, third roller, second inner circle, connecting bolt, third sealing washer etc. Under bearing same load condition, the utility model discloses outer three row tooth -like cylindrical roller slewing bearing is littleer than the overall dimension of other type supportings, but weight reduction practices thrift the metal, and this product bears the heavy slewing bearing more than the 200T, through optimizing inner structure, with minimum space, bears great load, solves bridge best between steel factory converter and the continuous casting.
Description
Technical field
The present invention relates to technical field of bearings, more particularly, it relates to heavy duty crane external tooth type three-row cylinder roller pivoting support.
Background technology
Pivoting support is a kind of large size bearing that can bear combined load, it is possible to bear bigger axial, radial load and tilting moment simultaneously.Three row's roller pivoting supports have three seat rings, and upper and lower and radial direction raceway is individually separated so that the load of each row's roller can be determined definitely.Various load can be born simultaneously, it it is the one that in four kinds of products, bearing capacity is maximum, axle, radial dimension are all bigger, sound construction, it is particularly well-suited to the larger-diameter heavy-duty machinery of requirement, such as bucket-wheel excavator, wheeled crane, ship's crane, portal crane, molten steel operating platform and tonnage automobile crane etc. are mechanically.
Summary of the invention
Present invention aim at as harbour, a kind of pivoting support of power plant crane research and development, this pivoting support can reach to reduce the contact load of roller and raceway, improve the effect of bearing capacity, alleviate weight by optimizing structure, save metal, there is the feature of convenient processing simultaneously.
For reaching above-mentioned purpose, the invention provides a kind of external tooth type three-row cylinder roller pivoting support, including: inner ring, external toothing, and the three row's cylindrical roller arranged between the two；
The described external toothing outer wall middle and upper part some dentation fins of circumference uniform distribution；In described external toothing, wall circular arranges the fin extended internally；
Described inner ring includes the first inner ring and the second inner ring；Described first inner ring is anchored on above described second inner ring by connecting bolt；
In described first inner ring and second, ring outer wall annular arranges laterally zygomorphic two grades of step groove；
The fin that described two grades of step groove are arranged with described external toothing annular is inlayed and is coordinated, and forms three road ring raceways of upper, middle and lower distribution；
It is positioned at ring raceway first roller that fill level is arranged respectively of upper and lower, three rollers；Outside described first roller, parcel arranges the first shading ring, and outside described three rollers, parcel arranges the second shading ring；
The second roller being vertically arranged is filled by the annular ridge inwall of described external toothing and described first inner ring, the second level annular groove of ring outer wall is formed in second intermediate annular raceway；
Described first roller, the second roller, three rollers two ends be provided with convexity；
Described first inner ring external wall of upper portion and described external toothing roof are equipped with two seals circle, respectively the first sealing ring, the second sealing ring；Described external toothing bottom interior wall and the second inner ring diapire are equipped with the 3rd sealing ring；
Described external toothing is vertical with described inner ring wears hole, some location.
Present invention have an advantage that
1, the present invention is provided with three-row roller, and the vertical roller of two rows can bear axial force and the tilting moment of both direction；The second centrally located roller can bear radial force.
2, in the present invention, the end face of three-row roller and bottom surface are provided with convexity, reduce roller and raceway friction, improve the service life of pivoting support to greatest extent.
3, compared with the present invention supports with crossed pin roller type, under same supporting diameter, the quantity of rolling element adds, thus decrease the load on each rolling element, compared with supporting with double ball, point cantact after changing linear contact lay into, contact stress can be reduced, improve bearing capacity.
4, due to the fact that radial force and axial force are arranged roller by two and be respectively subjected to, the principal direction making the suffered load of opposite direction and supporting is consistent, thus can reduce the contact load of roller and raceway.
5, the raceway of rolling ring is plane and the face of cylinder, easy to process.
Under bearing same load condition, less than the overall dimensions of other type supporting, weight can be alleviated, save metal, this product bears the heavy pivoting support of more than 200T, by optimizing internal structure, with minimum space, bear bigger load, be solve bridge best between steel mill's converter and continuous casting.
