Description
Technical field
The utility model relates to the components on wind-powered electricity generation mounting platform crane, more specifically to a kind of large-scale point
Segmentation slewing bearing.
Background technique
Pivoting support bearing is called turntable bearing, is also called: rotationally supporting, bearing of circling round, is that one kind can be simultaneously
Bear the large size bearing of biggish axial load, radial load and tilting moment.Turntable bearing generally all has mounting hole, internal tooth
Wheel or external gear, oilhole and sealing device, thus can make main machine structure it is compact to design, guidance it is reliable, easy to maintain.Revolution
Bearing support is widely used in hoisting machinery, mining machinery, building machinery, harbour machinery, ship equipment and high-precision radar
On the huge revolving devices of equipment such as mechanical and missile launcher, while can also be designed, being developed according to the specific requirement of user,
Produce various special construction pivoting support bearings.
Currently, the maximum gauge for the monoblock type slewing bearing that can be manufactured is 9.5 meters, tilting moment is 6.3 ten thousand tons
Rice, but with the raising to crane job Capability Requirement, the slewing bearing on crane is also again toward enlargement side
To development, due to being limited by forge piece equipment and process equipment, the size of slewing bearing is just more than above-mentioned full-size
It cannot manufacture and produce, cause obstruction to the manufacture assembly of crane complete machine.
Utility model content
In view of the above defects of the prior art, the purpose of the utility model is to provide a kind of large-scale segmenteds to turn round
Spring bearing solves the problems, such as the forging and processing of huge revolving spring bearing.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of large size segmented slewing bearing, comprising: outer gear ring, inner ring upper piece and inner ring bottom sheet, inner ring upper piece and
Be overlapping setting up and down between inner ring bottom sheet, to form inner ring structure, offered on the lateral surface of inner ring structure for it is outer
The first sliding groove of gear ring assembly is connected with connection draw runner on the medial surface of outer gear ring, and connection draw runner is assemblied in first sliding groove, and first
It is also provided with second sliding slot in sliding slot, lateral roller is equipped in second sliding slot, lateral roller connects with the front end face for connecting draw runner
Touching, connect and be equipped with positive roller between the upper surface of draw runner and first sliding groove, connect draw runner lower end surface and first sliding groove it
Between be equipped with reversed roller.
Band is additionally provided between the outer gear ring and inner ring structure.
In the above technical solution, a kind of large-scale segmented slewing bearing provided by the utility model can be incited somebody to action
Slewing bearing is segmented by forge piece equipment and process equipment ability, then carries out assembled use, and this reality at the scene
Simple, reliable with the overall structure of Revolving support bearing, installation, maintenance is also convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model slewing bearing.
Specific embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 1, a kind of large-scale segmented slewing bearing provided by the utility model, comprising: external tooth
Circle 1, inner ring upper piece 2 and inner ring bottom sheet 3,3 be overlapping setting up and down between inner ring upper piece 2 and inner ring bottom sheet, to form inner ring
Structure offers the first sliding groove 4 for assembling with outer gear ring 1 on the lateral surface of inner ring structure, connects on the medial surface of outer gear ring 1
There is connection draw runner 5, connection draw runner 5 is assemblied in first sliding groove 4, second sliding slot is also provided in first sliding groove 4, in second sliding slot
It is equipped with lateral roller 6, lateral roller 6 and the front end face contact for connecting draw runner 5, connects upper surface and the first sliding groove of draw runner 5
It is equipped with positive roller 7 between 4, connects and is equipped with reversed roller 8 between the lower end surface and first sliding groove 4 of draw runner 5.
Preferably, band 9 is additionally provided between the outer gear ring 1 and inner ring structure, for preventing oil leak.
In the utility model slewing bearing, outer gear ring 1, inner ring upper piece 2 and inner ring bottom sheet 3 are circular ring structure, root
The segmentation of circumferencial direction is carried out according to forge piece equipment and process equipment ability, and former inner ring is as segmented into inner ring upper piece 2 and interior
Bottom sheet 3 is enclosed, it is assembled integral again after molding to be processed.
Firstly, outer gear ring 1, inner ring upper piece 2 and inner ring bottom sheet 3 are carried out segmentation casting and forging molding respectively, then by outer gear ring 1,
Inner ring upper piece 2 and inner ring bottom sheet 3 carry out segmentation roughing respectively, and outer gear ring 1, inner ring upper piece 2 and inner ring bottom sheet 3 are carried out for the first time
It is assembled integral, after finishing, pre-assembled is carried out with lateral roller 6, positive roller 7 and reversed roller 8, it is errorless to pre-assembled
Afterwards, it will integrally split again, the transport of all parts sectional after fractionation, and reach assembled integral again behind scene, in wind-powered electricity generation
It is installed in place on mounting platform crane.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate that this is practical new
Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to the above
Variation, the modification of embodiment will all be fallen in the Claims scope of the utility model.
