Description
Technical field
The utility model belongs to technical field of bearings, relates generally to a kind of structural type of enhanced type entity holder thrust self-aligning roller bearing.
Background technique
At present, entity holder thrust self-aligning roller bearing, as shown in Figure 1: it is made up of seat ring 1.1, blowout patche 1.2, roller 1.3, retainer 1.4 and lining 1.5; Its characteristics are: retainer adopts the blowout patche lip-guided, and retainer is cohesive type (sees Fig. 1 1.4), adopts roller major part load mode, and lining is held roller locks on blowout patche.This airframe bearing has advantages such as resistance to shock and aligning performance be good.But shortcomings such as owing to be subjected to the restriction of structural design, machining accuracy and bearing assembly technology, this product ubiquity bearing capacity is low, the life-span short, greasy property is poor, the easy sequence of sanqu songs within a particular musical mode.
Summary of the invention
The purpose of this utility model provides a kind of enhanced type entity holder thrust self-aligning roller bearing, this bearing has bearing capacity height, long service life, running is steady, greasy property good, hang down advantages such as friction, resistance to shock and aligning performance are good, has solved the sequence of sanqu songs within a particular musical mode problem of bearing.
The purpose of this utility model can adopt following technological scheme to realize: its part comprises seat ring, blowout patche, roller, retainer and lining.Retainer is the mode of lining guiding; Lining is locked on the blowout patche, makes blowout patche, roller and retainer become inseparable assembly; Roller small end face is concave spherical surface SR; Retainer adopts roller microcephaly load mode for extending out the formula structure; The end face of sleeve is a planar end surface, and the end face on lining top along the circumferential direction is provided with equidistant square groove, drives oil groove on the internal diameter, is evenly equipped with oilhole on oil groove.
The inclined-plane of blowout patche rib changes planar end surface into; Retainer pocket hole is that cambered surface contacts with the rolling surface of roller.
By last structure as can be seen, what the utility model designed changes the mode that lining guides into by the blowout patche lip-guided, and the rib end face of blowout patche changes planar end surface into by the inclined-plane, has reduced the technology difficulty of heat treatment and mill processing, has improved the precision of processing.Roller small end face is concave spherical surface SR, has reduced the area of contact that roller small end face and retainer are revealed all the details, and can store certain lubricant grease, has reduced the frictional force that roller and retainer are revealed all the details again.Extend out the formula retainer, adopt roller microcephaly load mode, the deck-siding between the retainer two pocket holes is narrowed down, can suitably increase roller diameter or quantity, thereby improve the load capacity of bearing, retainer pocket hole is that cambered surface contacts with the rolling surface of roller, makes the running of bearing more steady.The planar end surface of lining is held retainer, roller and blowout patche assembly and is played guiding function, end face on lining top along the circumferential direction is milled with equidistant square groove, the locking intensity of lining and blowout patche has reduced the difficulty of locking technology when having increased the bearing assembling, has thoroughly solved the sequence of sanqu songs within a particular musical mode problem of bearing; On the lining internal diameter, drive oil groove, on oil groove, be evenly equipped with oilhole, be beneficial to lubricant grease and successfully enter bearing inside, the greasy property of bearing is improved.In sum, advantage such as the utlity model has bearing capacity height, long service life, running is steady, greasy property good, low friction, resistance to shock and aligning performance are good has solved the sequence of sanqu songs within a particular musical mode problem of bearing.

Embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 2: its part of the utility model bearing comprises seat ring 1, blowout patche 2, roller 3, retainer 4 and lining 5.
As shown in Figure 3: change lining 5 guiding into by blowout patche 2 lip-guideds, change the inclined-plane of the rib end face of blowout patche 2 into planar end surface 6, reduced the technology difficulty of heat treatment and mill processing, improved the precision of processing.
As shown in Figure 4: roller 3 small end faces are concave spherical surface SR, have reduced the area of contact that roller 3 small end faces and retainer 4 are revealed all the details, and can store certain lubricant grease, have reduced the frictional force that roller 3 and retainer 4 are revealed all the details again.
As shown in Figure 5: the shape of optimizing retainer 4 pocket holes, strengthen the intensity that retainer 4 is revealed all the details, adopting radius of curvature is the tack milling cutter processing pocket hole of 0.51～0.53R, and making the retainer 4 pocket holes and the rolling surface of roller 3 is that cambered surface contacts, and makes the running of bearing more steady.
