Description of drawings
Fig. 1 is overall structure schematic representation of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: this bearing used for high-speed braider, be included in the inner ring of axle 8 outer sockets, be socketed with outer ring 1 outside inner ring, the right part of described axle 8 has block plate 8.1, be bolted with setting sleeve 7 in axle 8, described inner ring is arranged on the axle 8 between setting sleeve 7 and the block plate 8.1; 1 internal surface left side has left side raceway outer course in the outer ring, outer surface at inner ring has road in the raceway of left side, in left side raceway outer course and left side raceway, be provided with the tapered roller 3 that is positioned at the left side between the road, be provided with the left side retainer at the tapered roller 3 that is positioned at the left side; 1 internal surface right side has right side raceway outer course in the outer ring, outer surface at inner ring has road in the raceway of right side, in right side raceway outer course and right side raceway, be provided with the tapered roller 3 that is positioned at the right side between the road, be provided with the right side retainer at the tapered roller 3 that is positioned at the right side; Be equipped with seal ring 6 on the left of the internal surface of outer ring 1 and between the outer surface of setting sleeve 7 and between the outer surface of the internal surface right side of outer ring 1 and block plate 8.1; The position of block plate 8.1 is pointed on the described summit that is positioned at the tapered roller 3 place circular cones in left side, and the position of setting sleeve 7 is pointed on the described summit that is positioned at the tapered roller 3 place circular cones on right side; The bus of described tapered roller 3 is the circular arc of evagination, and outwards protruding 4 ~ 6 μ m in the bus of tapered roller 3 middle part.
Left side raceway outer course and the right side raceway outer course of described outer ring 1 internal surface are conical surface, and equal inwardly protruding 4 ~ 6 μ m in the bus of the left side raceway outer course of outer ring 1 internal surface and right side raceway outer course middle part.
In the left side raceway of described inner ring outer surface in road and the right side raceway road be conical surface, and equal outside protruding 4 ~ 6 μ m in the bus middle part in road in road and the right side raceway in the left side raceway of inner ring outer surface.
Described inner ring comprises left side inner ring 2.1 and right side inner ring 2.2, the road is opened on the outer surface of left side inner ring 2.1 in the raceway of described left side, the road is opened on the outer surface of right side inner ring 2.2 in the raceway of right side, and has pad 5 between left side inner ring 2.1 and the right side inner ring 2.2.
Offer lubrication hole 8.2 in axle 8, the outlet end of lubrication hole 8.2 is opened on the sidewall of axle 8 of pad 5 positions.
The present invention is because outwards protruding 4 ~ 6 μ m in bus middle part of its tapered roller 3, the left side raceway outer course of outer ring 1 internal surface and the bus of right side raceway outer course middle part be inwardly protruding 4 ~ 6 μ m all, the bus middle part in the interior road of the left side raceway of inner ring outer surface and the interior road of right side raceway is outwards protruding 4 ~ 6 μ m all, tapered roller 3 and outer ring 1, between tapered roller 3 and the left side inner ring 2.1 and tapered roller 3 and outer ring 1, being line between tapered roller 3 and the right side inner ring 2.2 contacts, area of contact is little, wearing and tearing are just few, rotate more flexible, can adapt to high rotating speed needs, correspondingly also just greatly prolong working life.
The outer surface of outer ring 1 be the middle part heave cylindrical, this columniform bus is circular arc, and this columniform bus place radius of a circle is 400 ~ 600mm, the bearing stress that is conducive to like this bearing concentrates on the intermediate portion of bearing, avoid stress concentration at two chamfer places of bearing, the early failue of generation.
