Abstract
The invention relates to a special wheel hub for a long board wheel, a scooter wheel or a skating wheel. The wheel hub comprises a bearing mounting side inner ring and a PU wheel body side outer ring which is integrally molded with the bearing mounting side inner ring, wherein a plurality of axial through holes are uniformly distributed on the outer ring along the circumference; axial gaps in one-to-one correspondence to the through holes are distributed on the outer circumferential face of the outer ring and communicated with the axial through holes in the diameter direction of the wheel hub. The special wheel hub for the long board wheel, the scooter wheel or the skating wheel, disclosed by the invention, has the following advantages: compared with the traditional technology, the axial gaps in one-to-one correspondence to the through holes are distributed on the outer circumferential face of the outer ring and communicated with the axial through holes in the diameter direction of the wheel hub, so that when the wheel hub with such structure is combined with a wheel body coated with polyurethane, the wheel hub can ensure smooth exhaust, combines with the wheel body coated with polyurethane excellently, and further greatly improves the product yield and quality.
Description
Technical field
The present invention relates to sports equipment, particularly to a kind of long slab wheel, slide plate wheel or Roller skate special wheel hub.
Background technology
Long slab wheel, slide plate wheel or Roller skate are chain-wales having two or more wheels, scrunch ground by user and advance.Wherein, wheel should the body weight of support people, also want rolls forward simultaneously, be one of the important accessory of long slab wheel, slide plate wheel or Roller skate.In prior art, long slab is taken turns, the wheel hub of slide plate wheel or Roller skate, PU including bearing installation side inner ring and with bearing installation side inner ring global formation takes turns outer ring, side, and outer ring is circumferentially evenly distributed with some axially extending bores, then transparent or nontransparent polyurethane wheel body it is surrounded by outside the outer ring of wheel hub, and then constitute long slab wheel, slide plate wheel or Roller skate, the wheel hub of this structure, outer ring has circumferentially equally distributed through hole, the design of through hole makes it in the fabrication process, make polyurethane can inject in the wheel body cavity formed between wheel hub and mould smoothly, and quickly discharge the air in cavity.
But this structure still suffers from certain defect: the wheel hub of this structure is in manufacturing long slab wheel, slide plate wheel or slide plate wheel process, though to a certain extent can aerofluxus smoothly, but exhaust effect is still not good enough, still suffer from partial air cannot be discharged, form pore in this region after perfusion, in turn result in perfusion defect, thus qualification rate and the quality of product can be affected.
Therefore, research and develop a kind of good exhaust effect and can the long slab wheel of improving product qualification rate and quality, slide plate wheel or Roller skate special wheel hub be necessary.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of good exhaust effect and can the long slab wheel of improving product qualification rate and quality, slide plate wheel or Roller skate special wheel hub.
For solving above-mentioned technical problem, the technical scheme is that a kind of long slab wheel, slide plate wheel or Roller skate special wheel hub, described wheel hub includes bearing installation side inner ring and the PU with bearing installation side inner ring global formation takes turns outer ring, side, described outer ring is circumferentially evenly distributed with some axially extending bores, its innovative point is in that: on the outer circumference surface of described outer ring, distribution has and through hole axial slits one to one, and this axial slits connects axially extending bore in the diametric(al) of wheel hub.
Further, the cross section of described through hole is circular, waist type or sector.
Further, when described through hole is manhole, the air line distance of the centre-to-centre spacing outer ring outer peripheral face of described manhole is less than the radius of manhole.
It is an advantage of the current invention that:
(1) the long slab wheel of the present invention, slide plate wheel or Roller skate special wheel hub, compared with conventional art, the outer circumference surface of outer ring is distributed and has and through hole axial slits one to one, this axial slits connects axially extending bore in the diametric(al) of wheel hub, the wheel hub of this structure and outsourcing polyurethane wheel body in conjunction with time, can either guarantee that aerofluxus is smooth, outsourcing polyurethane wheel body and wheel hub can be made again to have the combination of excellence, and then qualification rate and the quality of product can be greatly promoted；
(2) the long slab wheel of the present invention, slide plate wheel or Roller skate special wheel hub, the through hole that outer ring is provided with is manhole or waist typed through hole or fan-shaped pylone, according to actual needs, can select corresponding through hole, and then make the product manufactured have multiformity；When through hole is manhole, the air line distance of the centre-to-centre spacing outer ring outer peripheral face of manhole is less than the radius of manhole, and so, the wheel hub of this structure is in manufacturing long slab wheel or slide plate wheel process, it is possible to make exhaust effect better.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of embodiment 1 in the present invention.
Fig. 2 is the structural representation of embodiment 2 in the present invention.
