Description
Technical field
The utility model provides a kind of slewing bearing with three rows of rollers, is related to pivoting support field.
Background technology
The roller that traditional roller pivoting support is selected is isodiametric cylinder, but due to this isodiametric cylinder
Body foot axis is placed along the radial direction of pivoting support, and which results in wherein one end to slide, and on the one hand accelerates roller
With the abrasion of raceway, on the other hand cause to rotate dumb, rub-moment increase, and existing pivoting support radial load is insufficient,
To which revolving support is easily damaged, service life is short.
It is existing to be obliquely installed upper raceway or lower raceway to enhance its axial, radial direction and stress of toppling ability, to match
Suitable close lays particular stress on the design that the heavy lifting equipment of stress is selected, but it is improved relative to single crossed pin roller type pivoting support
Advantage is not obvious.
Invention content
In order to solve problem above, the utility model provides a kind of slewing bearing with three rows of rollers, this kind of pivoting support
Reasonable for structure, service life is long, and can have higher stress of toppling.
The technical solution of the utility model is as follows：A kind of slewing bearing with three rows of rollers, including external toothing and ring gear, institute
It includes the interior Shang Quan and Nei Xiaquan connected by fastener to state ring gear, and the annular infraoral position of the interior upper circle is equipped with ladder
The middle part vertical plane of slot, the stepped groove and external toothing annular inner wall, which is combined into, is vertically arranged raceway in rectangle, in the middle raceway
It is arranged with the roller and spacing block being spaced apart, being opened on the annular outer wall of the interior Shang Quan and interior lower circle has right-angled trapezium slot,
The position suitable for reading and infraoral position of the external toothing annular inner wall are equipped with inclined surface corresponding with the inclined side of right-angled trapezium slot；It is interior
After gear ring is assembled with external toothing, the interior upper circle right-angled trapezium slot of annular outer wall and inclining for external toothing annular inner wall position suitable for reading
Inclined-plane constitutes tilting upper raceway, right-angled trapezium slot and the external toothing annular inner wall position suitable for reading of the interior lower ring shape outer wall
Inclined surface constitutes tilting lower raceway；Inclination roller is installed, adjacent inclination roller intersects in the upper raceway and lower raceway
Arrangement and orthogonal arrangement.
Technical solutions of the utility model further include：The upper raceway is opposite with the lower angle of inclination of raceway.
Technical solutions of the utility model further include：The external toothing is respectively set when engagement with interior Shang Quan and interior lower circle
There is sealing ring.
The beneficial effects of the utility model are：The utility model provides a kind of slewing bearing with three rows of rollers, this kind returns
It is two rows is staggered form roller to turn bearing, the intermediate arrangement for vertical roller, in the design of existing inclined races, into one
Step reinforces bearing capacity of the revolving support for radial and axial both direction, and combines slewing bearing with three rows of rollers and list
The advantages of arranging roller pivoting support, disclosure satisfy that bearing capacity is strong, and to bearing axial force, tilting moment and larger radial direction
The machinery that power has higher requirements, applied widely, service life is long, has good practicability.
Description of the drawings
Fig. 1 is the utility model slewing bearing with three rows of rollers structural schematic diagram；
Fig. 2 is that roller path structure schematic diagram is arranged on the utility model；
Wherein, 1, external toothing, 2, interior upper circle, 3, Nei Xiaquan, 4, upper raceway, 5, lower raceway, 6, middle raceway, 7, sealing ring,
8, roller is tilted.
Specific implementation mode
The utility model is described further below in conjunction with drawings and examples.
Simultaneously as only position embodiment described below, in the absence of conflict, embodiment in the application and
Feature in embodiment can be combined with each other.
A kind of slewing bearing with three rows of rollers, including external toothing 1 and ring gear, the ring gear include being connected by fastener
The interior upper circle 2 and interior lower circle 3 connect, the annular infraoral position of the interior upper circle 2 are equipped with stepped groove, the stepped groove and external toothing 1
The middle part vertical plane of annular inner wall, which is combined into, is vertically arranged raceway 6 in rectangle, and the roller being spaced apart is arranged in the middle raceway 6
And spacing block, it opens and has right-angled trapezium slot on the annular outer wall of the interior upper circle 2 and interior lower circle 3,1 annular inner wall of the external toothing
Position suitable for reading and infraoral position be equipped with inclined surface corresponding with the inclined side of right-angled trapezium slot；Ring gear is assembled with external toothing 1
Afterwards, the right-angled trapezium slot of 2 annular outer walls of the interior upper circle and the inclined surface at 1 annular inner wall of external toothing position suitable for reading are constituted tilting
Upper raceway 4, the right-angled trapezium slot of 3 annular outer walls of the interior lower circle are constituted with the inclined surface at 1 annular inner wall of external toothing position suitable for reading
