Description
Technical field
The utility model relates to a kind of bearing roller, especially relates to a kind of slag mechanical straps deep hole bearing roller.
Background technique
Along with the development of technology, the level of integration of hub-bearing unit is more and more higher.Bearing unit has generally comprised inner ring, outer ring, is fixed with single-row or biserial roller between Internal and external cycle by retainer.Chinese patent discloses a kind of hub-bearing unit (Authorization Notice No.: CN201671960U), and it comprises flange plate, inner ring, outer ring, ball, interior retainer, outer retainer, and inner ring is arranged on the end outside flange plate; Described outer ring is arranged on the root outside flange plate, the first raceway groove and second raceway groove of ring-type is provided with between outer ring and flange plate and inner ring, first raceway groove is in side, flange plate end, second raceway groove is in flange plate root side, ball is provided with in the first raceway groove and the second raceway groove, outer ring and flange plate and inner ring are arranged ball by described two and are rolled and be connected, interior retainer is arranged in the first raceway groove, outer retainer is arranged in the second raceway groove, the diameter of the second raceway groove is greater than the diameter of described first raceway groove, and the ball in the second raceway groove is more than the ball in the first raceway groove; Flange plate end is provided with the crimping with flange plate one, and crimping is close to one end of described inner ring; First raceway groove is built with 18 balls, and the second raceway groove is built with 20 balls; Inner ring is also provided with speed sensor outward, and speed sensor comprises magnetic induction head and alloy tooth annulus.Chinese patent also discloses a kind of automobile hub bearing (Authorization Notice No.: CN201401445), it comprises flange plate inner ring, flange plate outer ring, inside race, ball and retainer, flange plate outer ring internal surface is provided with two outer raceways, flange plate inner ring with inside race outer surface is respectively provided with corresponding with outer raceway in raceway, ball is placed in retainer inscribe between interior raceway and outer raceway, flange plate inner ring outer surface have annular groove and step surface, annular retaining ring is provided with in groove, inside race one end face is resisted against on annular retaining ring, other end is resisted against on step surface.But these bearing units bearing roller used can only be applied on automobile, and cannot be used in the larger environment of dust, dust easily causes wearing and tearing to roller, and the working life of roller is shorter, easily causes security incident.
Model utility content
The utility model is to provide a kind of slag mechanical straps deep hole bearing roller, its bearing roller mainly solving bearing unit existing for prior art used can only be applied on automobile, cannot be used in the larger environment of dust, dust easily causes wearing and tearing to roller, the working life of roller is shorter, easily causes the technical problem of security incident etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Slag mechanical straps deep hole bearing roller of the present utility model, comprise roller body, through hole is had in the middle of described roller body, the two ends of through hole are communicated with indent platform by arc transition mouth, indent platform edges is arc surface, and the arc surface diameter of indent platform edges is less than the arc surface diameter of roller body.Arc surface diameter due to indent platform edges is less than the arc surface diameter of arc transition mouth, such cylindrical roller is when assembling, because the radius of arc transition mouth is larger, therefore, it is possible to guide needle roller to load through hole comparatively easily, and the arc surface diameter of indent platform edges is less, make the surface of contact of itself and bearing support less, thus the probability reduced wear.The length of whole cylindrical roller is 146.507mm, and therefore its through hole is deep hole, can the longer needle roller of cross-under.
As preferably, the inwall of described through hole has some cavitys, the A/F of cavity is less than cavity inside width.When after roller length service time one, can leave the chip after wearing and tearing in through hole, scrap collecting can get up by cavity, and because the width of cavities open is less, therefore chip can not be run out and is positioned on inwall, decreases wearing and tearing probability, extends working life.
As preferably, the edge of described roller body is provided with arc round angle.The area of contact of roller body end face and bearing support can be reduced by arc round angle, thus reduce wear.
As preferably, the end face of described roller body has annular groove, in annular groove, is embedded with carbon seal ring.Can increase abrasion resistance on the one hand by carbon seal ring, can also reduce dust enters into through hole inside on the other hand.
Therefore, the utility model arranges multiple arc surface on cylindrical roller, and arranges cavity in through hole, the area of contact of cylindrical roller and bearing support can be reduced, and the chip that gets off of reducing wear is on the impact of roller, and working life is longer, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering in figure: roller body 1, through hole 2, arc transition mouth 3, indent platform 4, cavity 5, arc round angle 6, annular groove 7, carbon seal ring 8.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the slag mechanical straps deep hole bearing roller of this example, as Fig. 1, comprise roller body 1, through hole 2 is had in the middle of roller body, the two ends of through hole are communicated with indent platform 4 by arc transition mouth 3, and indent platform edges is arc surface, and the arc surface diameter of indent platform edges is less than the arc surface diameter of arc transition mouth 3, the arc surface diameter of indent platform edges is 3.04mm, and the arc surface diameter of arc transition mouth 3 is 9.5mm.The inwall of through hole has some cavitys 5, the A/F of cavity is less than cavity inside width.The edge of roller body is provided with arc round angle 6.The end face of roller body has annular groove 7, in annular groove, be embedded with carbon seal ring 8.
During use, the utility model is encased in the bearing of slag machinery.
