Description of drawings
Fig. 1 is an overall structure schematic representation of the present invention.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure: this high-speed knitter is used bearing; Be included in the inner ring of axle 8 outer sockets, outside inner ring, be socketed with outer ring 1, the right part of described axle 8 has block plate 8.1; On axle 8, be bolted with setting sleeve 7, 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, on the tapered roller 3 that is positioned at the left side, be provided with left side retainer 4.1; 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, on the tapered roller that is positioned at the right side 3, be provided with right side retainer 4.2; 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 said 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 said summit that is positioned at the tapered roller 3 place circular cones on right side; The bus of said tapered roller 3 is the circular arc of evagination, and the bus of tapered roller 3 middle part is to outer lug 4 ~ 6 μ m.
The 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.
The interior road of road and right side raceway is conical surface in the left side raceway of described inner ring outer surface, and the bus middle part in interior road of the left side raceway of inner ring outer surface and the interior road of right side raceway is all to outer lug 4 ~ 6 μ m.
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 said 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.
On axle 8, offer lubrication hole 8.2, the outlet end of lubrication hole 8.2 is opened on the sidewall of axle 8 of pad 5 positions.
The present invention since the bus of its tapered roller 3 middle part to the bus middle part of the left side raceway outer course of outer lug 4 ~ 6 μ m, outer ring 1 internal surface and right side raceway outer course all in the left side raceway of inwardly protruding 4 ~ 6 μ m, inner ring outer surface in road and the right side raceway in the middle part of the bus in road all to outer lug 4 ~ 6 μ m; Being line between between tapered roller 3 and outer ring 1, tapered roller 3 and the left side inner ring 2.1 and tapered roller 3 and outer ring 1, 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 flexibly, can adapt to high rotating speed needs, correspondingly also just greatly prolonged working life.
The outer surface of outer ring 1 be the middle part heave cylindrical; This columniform bus is a circular arc; And this columniform bus place radius of a circle is 400 ~ 600mm; The bearing stress that helps bearing like this concentrates on the intermediate portion of bearing, avoids stress concentration at two chamfer places of bearing, the early failue of generation.
