Abstract
The utility model discloses a center adjusting roller bearing with an over-sized solid retainer, which comprises the parts of an outer ring (1), an inner ring (2), a roller (3), a retainer (4) and a middle blocking ring (5). The utility model is characterized in that two small blocking edges of the inner ring (2) are respectively provided with a gap (9) with a roller (3); an arc central line of the gap (9) parallels to a central line (6) of the roller (3); the retainer (4) adopts a dual claw type; two sides of the retainer (4) are provided with holding holes in sequence; places from one third on bottoms of two holding holes of outer diameter on the retainer (4) are respectively provided with an inclined plane (10) which parallels to the central line of (6) of the holding hole and crosses on two end surfaces (11) of the holding hole. The structure of the roller bearing guarantees the assembly quality of products, avoids the occurrence of damages and scratches on the roller and a rolling channel, remarkably improves the vibration and noise of the bearing, leads operation of the bearing to be more stable, improves the assembly efficiency and lightens the labor intensity.
Description
Technical field
The utility model belongs to technical field of bearings, relates generally to a kind of structural type of super-huge solid cage selfaligning roller bearing.
Background technique
At present, the super-huge solid cage selfaligning roller bearing of China's outside dimension above 400 millimeters generally uses on equipment such as mine, metallurgy, water conservancy, wind-power electricity generation, vibrating machine, cement.This class bearing has advantages such as the high and aligning performance of bearing capacity is good.But owing to there is inadequate natural endowment (dress roller breach and bearing centre line parallel, contain too much in retainer pocket hole) in bearing structure, when causing assembling, ubiquity roller and raceway chew and scratch phenomenon, so that bearing vibration and noise increasing, and shorten working life.
Summary of the invention
Advantages such as the purpose of this utility model provides a kind of super-huge solid cage selfaligning roller bearing of architecture advances, and this airframe bearing has bearing capacity height, long service life, vibration, noise is little, running is steady, aligning performance is good.
The purpose of this utility model can adopt following technological scheme to realize: its part comprises outer ring, inner ring, roller, retainer and guide ring.
Have oil groove on the external diameter center line of outer ring, on oil groove, be evenly equipped with oilhole; Inner ring is the structural type of two little ribs of no centre rib band, respectively is provided with the breach of a dress roller on two little ribs, and two breach are separated by 180 °, the center of arc's line and the roller centre line parallel of dress roller breach; Roller is the spherical roller of symmetry; The pocket hole of taking turns, double-claw type retainer both sides, rise at 1/3rd places by bottom, retainer external diameter two pocket holes, respectively have one parallel with the pocket centerline hole and meet at the inclined-plane of pocket hole both ends of the surface.
The utility model structure has guaranteed the assembly quality of product, has stopped the generation that roller and raceway chewed and scratched phenomenon, has obviously improved bearing vibration and noise, makes bearing operation more steady, and has improved efficiency of assembling, alleviated labor intensity.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the inner ring structural representation.
Accompanying drawing 3 is the retainer structural representation.
Among the figure: 1, outer ring, 2, inner ring, 3, roller, 4, retainer, 5, guide ring, 6, center line, 7, oil groove, 8, oilhole, 9, breach, 10, the inclined-plane, 11, end face.
Embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 1: its part of the utility model bearing comprises: outer ring 1, inner ring 2, roller 3, retainer 4 and guide ring 5.Have oil groove 7 on the 1 external diameter center line of outer ring, on oil groove 7, be evenly equipped with oilhole 8, be beneficial to the inside that lubricant grease enters bearing, improve the greasy property of bearing.Roller 3 is the spherical roller 3 of symmetry.
As shown in Figure 2: the breach 9 that on two little ribs of inner ring 2, respectively is provided with a dress roller 3, two breach 9 are separated by 180 °, center of arc's line of dress roller 3 breach 9 is parallel with roller 3 center lines 6, made things convenient for packing into of roller 3, when having avoided roller 3 to pack into and raceway chew and scratch phenomenon, improved the quality and the efficient of product assembling.
As shown in Figure 3: the pocket hole of taking turns, double-claw type retainer both sides, rise at 1/3rd places by bottom, retainer 4 external diameters two pocket holes, an inclined-plane 10 parallel with pocket centerline hole 6 is respectively arranged, inclined-plane 10 meets at the both ends of the surface 11 in pocket hole, it has solved because of containing too much in retainer 4 pocket holes, the interference problem that occurs when roller 3 is packed into has alleviated working strength.
Claims (4)
1, a kind of super-huge solid cage selfaligning roller bearing, its part comprises: outer ring (1), inner ring (2), roller (3), retainer (4) and guide ring (5), it is characterized in that: respectively be provided with the breach (9) of a dress roller (3) on two little ribs of inner ring (2), center of arc's line of breach (9) is parallel with roller (3) center line (6); Retainer (4) is a double-claw type, the pocket hole of taking turns, retainer (4) both sides, rise at 1/3rd places by bottom, retainer (4) external diameter two pocket holes, respectively have one parallel with pocket centerline hole (6) and meet at the inclined-plane (10) of pocket hole both ends of the surface (11).
2, super-huge solid cage selfaligning roller bearing according to claim 1 is characterized in that: two breach (9) that are used to adorn roller are separated by 180 °.
3, super-huge solid cage selfaligning roller bearing according to claim 1 is characterized in that: have oil groove (7) on the external diameter center line of outer ring (1), be evenly equipped with oilhole (8) on oil groove (7).
4, super-huge solid cage selfaligning roller bearing according to claim 1 is characterized in that: roller (3) is the spherical roller (3) of symmetry.
