Description
Technical field
The utility model provides a kind of tapper roller pivoting support, is related to pivoting support field.
Background technology
The roller that traditional roller pivoting support is selected is isodiametric cylinder, this isodiametric cylinder foot axis
Line 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 and raceway
Abrasion, on the other hand cause to rotate dumb, rub-moment increases, and is easily damaged to revolving support, service life is short.
The stress of toppling of existing three rows tapper roller pivoting support is weaker simultaneously, for laying particular stress on the heavy-duty hoisting of stress
For equipment and it is not suitable for.
Invention content
In order to solve problem above, the utility model provides a kind of tapper roller pivoting support, can effectively slow down
The case where rolling element slides, while enhancing the stress of toppling of pivoting support.
The technical solution of the utility model is as follows：A kind of tapper roller pivoting support, including external toothing and ring gear, institute
It includes the interior Shang Quan and Nei Xiaquan connected by fastener to state ring gear, and annular convex platform is provided on the inside of the external toothing, described
The upper surface of annular convex platform and the side of interior upper circle form raceway, the side shape of the lower surface of the annular convex platform and interior lower circle
At lower raceway, the side of the annular convex platform and raceway, the upper raceway in the setting of the seam allowance junction of interior Shang Quan and interior lower circle
Tapper is inside installed, middle raceway roller is installed in the middle raceway, roller, adjacent roller phase are installed in the lower raceway
Mutual arranged crosswise is simultaneously orthogonal.
The cone angle of the tapper is 0.1 °~10 °.
In the upper raceway spacing block is provided between tapper.
The external toothing is respectively arranged with sealing ring when engagement with interior Shang Quan and interior lower circle.
The beneficial effects of the utility model are：The utility model provides a kind of tapper roller pivoting support, rolls thereon
Tapper is installed in road, and middle raceway installs roller, the pivoting support structure of lower raceway installation staggered form roller, the tapper design of upper raceway
The problem of sliding can be mitigated, reduce the abrasion condition of rolling element, the rolling element in lower raceway is staggered form roller design, energy
Enough enhancing pivoting support is axial, ability of radial direction and stress of toppling, can be used in the heavy lifting equipment for being suitble to lay particular stress on stress choosing
With with good practicability.
Description of the drawings
Fig. 1 is the utility model tapper roller pivoting support schematic diagram；
Wherein, 1, external toothing, 2, interior upper circle, 3, Nei Xiaquan, 4, upper raceway, 5, lower raceway, 6, middle raceway, 7, tapper, 8,
Horizontal roller, 9, vertical roller, 10, middle raceway roller.
Specific implementation mode
The utility model is described further below in conjunction with drawings and examples.
Simultaneously as only section Example described below, in the absence of conflict, embodiment in the application and
Feature in embodiment can be combined with each other.
A kind of tapper roller pivoting support, 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 inside of the external toothing 1 are provided with annular convex platform, the upper surface of the annular convex platform with it is interior on
The side of circle 2 forms raceway 4, and the lower surface of the annular convex platform and the side of interior lower circle 3 form lower raceway 5, the annular
The side of boss and raceway 6 in the seam allowance junction setting of interior upper circle 2 and interior lower circle 3, are equipped with tapper 7 in the upper raceway 4,
Middle raceway roller 10 is installed in the middle raceway 6, roller is installed in the lower raceway 5, adjacent roller intersects cloth
It sets and orthogonal；The cone angle of the tapper 7 is 0.1 °~10 °, within this range its antiskid row best results.
In the upper raceway 4 spacing block is provided between tapper 7.
The external toothing 1 is respectively arranged with sealing ring when engagement with interior upper circle 2 and interior lower circle 3.
The present solution provides a kind of upper raceways 4 to install tapper 7, raceway roller 10 during middle raceway 6 is installed, lower raceway 5
The pivoting support structure of staggered form roller is installed, the tapper design of upper raceway 4 can mitigate the problem of sliding, reduce rolling element
Abrasion condition, the rolling element in lower raceway 5 is staggered form roller design, can enhance axial pivoting support, radial direction and topple
The ability of stress can be used in the heavy lifting equipment for being suitble to lay particular stress on stress and select, has good practicability.
The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model
System, done all any modification, equivalent and improvement etc., should be included in this reality within the spirit and principle of the utility model
Within novel protection domain.
