Abstract
The utility model belongs to self lubricating centre regulating roller bearing, by the novel bearing of self-lubricating knuckle bearing and selflubricating roller bearing compound, remain the application characteristic of selflubricating roller bearing, simultaneously can by the augular offset between self-lubricating knuckle bearing auto modification structure slide rail and selflubricating roller bearing.Self lubricating centre regulating roller bearing is primarily of inner ring, centre circle and outer ring composition, inner ring, centre circle and the selflubricating liner between inner ring and outer ring composition self-lubricating knuckle bearing, realize the function of aligning, the augular offset between correcting principle slide rail and selflubricating roller bearing; Centre circle, outer ring and the selflubricating liner between centre circle and outer ring form selflubricating roller bearing, outer ring supporting structure slide rail, can roll in the relative outer ring of structure slide rail.Owing to adopting selflubricating liner, so in use without the need to regularly lubricating.
Description
Technical field
The invention belongs to self lubricating centre regulating roller bearing technical field, for substituting traditional selflubricating roller bearing, is the selflubricating roller bearing of the augular offset between a kind of auto modification structure slide rail and selflubricating roller bearing.
Background technique
When aircraft flap slat and vent window slide rail and pulley frame are installed, often because of reasons such as processing or alignment errors, cause between structure slide rail and selflubricating roller bearing and have augular offset, selflubricating roller bearing can not effectively be rolled by supporting structure slide rail relatively, and even selflubricating roller bearing stress is concentrated and lost efficacy or breakage.Self lubricating centre regulating roller bearing, the self lubricating centre regulating roller bearing of the augular offset between a kind of auto modification structure slide rail and selflubricating roller bearing, selflubricating roller bearing effectively can be rolled by supporting structure slide rail relatively, avoid selflubricating roller bearing stress to concentrate and lost efficacy or breakage.
Summary of the invention
The object of the invention is: a kind of novel self lubricating centre regulating roller bearing is provided, eliminate aircraft flap slat and vent window slide rail and pulley frame when installing, augular offset between structure slide rail and selflubricating roller bearing, selflubricating roller bearing effectively can be rolled by supporting structure slide rail relatively, avoid selflubricating roller bearing stress to concentrate and lost efficacy or breakage.
The technical solution of the utility model is: a kind of self lubricating centre regulating roller bearing, is characterized in that, is made up of inner ring 1, centre circle 2 and outer ring 3, and inner ring 1, centre circle 2 and selflubricating liner therebetween 4 form self-lubricating knuckle bearing; Centre circle 2, outer ring 3 and selflubricating liner therebetween 4 form selflubricating roller bearing, and selflubricating roller bearing supporting structure slide rail rolls relatively, the augular offset between self-lubricating knuckle bearing auto modification structure slide rail and selflubricating roller bearing.
The utility model has the advantages that: self lubricating centre regulating roller bearing is composited by self-lubricating knuckle bearing and selflubricating roller bearing, remain the application characteristic of selflubricating roller bearing, simultaneously can by the augular offset between self-lubricating knuckle bearing auto modification structure slide rail and selflubricating roller bearing.
Accompanying drawing explanation
Fig. 1 is traditional selflubricating roller bearing structural representation;
Fig. 2 is the structural representation of self lubricating centre regulating roller bearing of the present invention, wherein, and inner ring 1, centre circle 2, outer ring 3, selflubricating liner 4.
Fig. 3 is the schematic diagram of traditional needle roller selflubricating roller bearing application.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Be illustrated in figure 1 the structural representation of traditional selflubricating roller bearing.
As shown in Figure 2, be a kind of structural representation of the present invention, be made up of inner ring 1, centre circle 2 and outer ring 3, inner ring 1, centre circle 2 and selflubricating liner therebetween 4 form self-lubricating knuckle bearing; Centre circle 2, outer ring 3 and selflubricating liner therebetween 4 form selflubricating roller bearing, selflubricating roller bearing supporting structure slide rail rolls relatively, augular offset between self-lubricating knuckle bearing auto modification structure slide rail and selflubricating roller bearing, selflubricating liner can play self-lubricating function.
