There are 2 spheric arc raceways two, holding to be placed between outer ring and inner ring for inner ring outer surface, and roller is located at the pocket of retainer
In hole；The more original roller diameter of the roller diameter increases 10%, and roller length increases 5%, is set on revealing all the details in the pocket hole
There is the oily nest of inverted cone shape, the top surrounding of the oil nest and intersection of revealing all the details are transition arc.
Further, the spheric arc raceway one, spheric arc raceway two are matched with roller respectively, contact rate
It is 0.98.
Further, lubricating oil is filled in the oily nest.
Further, the diameter accuracy of the outer ring and inner ring is respectively 0.001mm.
Further, the inner peripheral surface in the pocket hole is the arc surface to match with roller peripheral surface.
Compared with prior art, advantageous effect is the utility model：
(1) the more original roller diameter of the diameter of roller increases 10%, and roller length increases 5%, keeps the radial direction of bearing specified
Dynamic loading Cr is improved than original bearing, and the integrated carrying ability of bearing is made to have increased significantly；
(2) the spheric arc raceway two of the spheric arc raceway one, inner ring of outer ring respectively with the peripheral surface of roller
It matches, contact rate is 0.98, and contact rate drops to 0.98 from the 0.99 of original bearing, and such roller and outer ring, inner ring connect
Contacting surface product is small, reduces friction, slows down Wen Sheng, and reduce resistance reduces cost to extend the maintenance period of equipment；
(3) the oil design of nest of revealing all the details makes bearing retainer be easier to process, and improves production efficiency, and in oily nest both
Lubricating oil can be stored, makes that there is lubricating oil always between roller and pocket hole, the contact area revealed all the details with roller can also be reduced,
Reduce friction coefficient, improves the service life of bearing.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As Figure 1-Figure 4, high-mechanic, high load capacity, long-life jaw crusher self-aligning roller bearing, including outer ring 1,
Inner ring 2, retainer 3 and roller 4；There is 1 inner surface of outer ring one 1-1 of spheric arc raceway, 2 outer surface of inner ring to have 2 balls
Two 2-1 of face shape arc raceway, retainer 3 are placed between outer ring 1 and inner ring 2, and roller 4 is located in the pocket hole 3-1 of retainer 3；It protects
The both sides for holding frame 3 are evenly equipped with axial pocket hole 3-1, and the cross-shaped arrangements of pocket hole 3-1 of both sides；4 diameter D of the roller is more original
Roller diameter increases 10%, and 4 length L of roller increases 5%, and the 3-2 that reveals all the details in the pocket hole 3-1 is equipped with inverted cone shape
Oily nest 3-3, the top surrounding of the oil nest 3-3 and the intersections 3-2 of revealing all the details are transition arc 3-5.
One 1-1 of spheric arc raceway, two 2-1 of spheric arc raceway are matched with roller 4 respectively, and contact rate is equal
It is 0.98, the contact area of such roller and outer ring, inner ring is small, reduces friction, slows down Wen Sheng, reduces resistance, to prolong
The maintenance period for having grown equipment, reduces cost；
Lubricating oil is filled in the oil nest 3-3.
The diameter accuracy of the outer ring 1 and inner ring 2 is respectively 0.001mm, makes roller 4 and roller surface is good contacts, axis
It holds service life and improves 15%-20%.
The inner peripheral surface of the pocket hole 3-1 is the arc surface 3-4 to match with 4 peripheral surface of roller, relative to original straight pocket
There is prodigious advantage in hole in the operating of bearing, and the roller in straight pocket hole is in unbalance stress, in fact it could happen that when the difference of roller both ends
Operating, and improved pocket hole 3-1 is not in such phenomenon, contact of the arc surface with arc surface ensures the operating of the two
Synchronism.
Such as model 23180CAW33 type self-aligning roller bearings, there is outer ring, inner ring, be placed between outer ring and inner ring
Retainer, two row rollers being placed in retainer pocket hole, the diameter of outer ring is consistent with the diameter of original outer ring, is 650mm, inner ring
Diameter it is consistent with the diameter of original inner ring, be 400mm；Original roller diameter is 63mm, and improved roller diameter D is
70mm, original roller length are 83mm, and improved roller length L is 87.5, and improved roller is reinforced roller, makes axis
The integrated carrying ability held has increased significantly, and radial dynamic load rating Cr improves 20-30% than original bearing；And pocket
The 3-2 that reveals all the details of hole 3-1 is equipped with the oily nest 3-3 of inverted cone shape, and lubricating oil, the setting of oily nest 3-3 are filled in oily nest 3-3
The contact area between roller and pocket hole can be reduced, easy to process, production efficiency is high, and has lubrication between roller and pocket hole
Oil lubrication reduces friction coefficient, improves the service life of bearing.Simultaneously the top surrounding of the oily nest 3-3 with reveal all the details
The intersections 3-2 are designed as transition arc 3-5, reduce the friction between roller 4 and pocket hole 3, and the lubricating action of lubricating oil is more preferable.
In addition, the spheric arc raceway two of the spheric arc raceway one of outer ring, inner ring matches with the peripheral surface of roller 4 respectively
It closes, contact rate is 0.98, and contact rate drops to 0.98 from the 0.99 of original bearing, the contact surface of such roller and outer ring, inner ring
Product is small, reduces friction, slows down Wen Sheng, and reduce resistance reduces cost to extend the maintenance period of equipment.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
