Because the small situation in radially installed space, the axial load that can bear by calculating can not meet customer need bearing, and justify
Taper roller bearing needs lengthening roller since it is desired that increasing load carrying capacity, causes lasso wall thickness thinning, difficulty of processing increase,
Easily there is stress concentration in lasso oil duct and marginal position, cause lasso fragmentation.Thus needing to develop one kind to fit
The space axial direction axially position bearing in the case that radial direction is small greatly should be filled.
Utility model content
The purpose of this utility model is to provide a kind of bidirectional propulsion self-aligning roller bearing, and it is axially big to can adapt to installing space
And the situation that radial direction is small, the requirement of user is adapted to, increases the service life of bearing, reduces the frequency for changing bearing.
The technical scheme of use is：
A kind of bidirectional propulsion self-aligning roller bearing, including blowout patche.
Technical points are：
Upper bushing is provided with the inside of the top of blowout patche, blowout patche is fixedly connected with upper bushing.
The raceway that the upper outer of blowout patche is provided with and axis is obliquely installed, and holder is provided with, the pocket of holder
It is provided with above-listed rolling element in hole, holder and above-listed rolling element are fastened on upper on the outside of upper bushing groove and blowout patche on the outside of upper bushing
Between projection.
Lower bushing is provided with the inside of the lower section of blowout patche, blowout patche is fixedly connected with lower bushing.
The raceway that the lower outer of blowout patche is provided with and axis is obliquely installed, and lower retainer is provided with, the pocket of lower retainer
Following rolling element is provided with hole, under lower retainer and following rolling element are fastened on the outside of lower bushing on the outside of lower bushing groove and blowout patche
Between projection.
Seat ring is provided with the outside of above-listed rolling element and following rolling element.
Seat ring includes top race and bottom race, and top race is located on the outside of above-listed rolling element, and bottom race is located at following rolling element
Outside, outer ring spacer is provided between top race and bottom race.
It the advantage is that：
The utility model improves bearing service life, reduces production line and often changes bearing, improves production efficiency, subtract
Production cost is lacked, has been adapted to fit space and is axially used in the case that radial direction is small greatly.
