Existing single row roller bearing, retainer wherein is split-type structural, it comprises the pocket hole between two beams that keep stand, retainer lid and be located at retainer, the bi-side of beam are the arc shaped surface with the rolling element surface engagement, cover and be provided with respectively vertically the rivet through hole at each beam that keeps stand and retainer, by the rivet be arranged in the rivet through hole, the retainer lid is connected and fixed with keeping stand during installation, thereby rolling element is locked in retainer pocket hole.Existence due to rivet through hole in the retainer of this kind of structure, and the arc shaped surface of the both sides of beam and rolling element surface engagement, cause the beam of its retainer thicker, gap between rolling element and rolling element is large, reduced the number of rolling element, reduced the bearing capacity of bearing, while working under the operating mode of single row roller bearing in high capacity of this kind of structure, its working life is lower.
The model utility content:
The utility model is in order to make up the deficiencies in the prior art, a kind of integrated cage formula single row roller bearing is provided, its reasonable in design, adopt integrated retainer, and its pocket hole is changed and is made as square pocket keeping rack, the long side surface of inner both sides, pocket hole is plane, by bearing pin, rolling element is locked in the pocket hole of retainer, reduced the thickness of cage bar, dwindle the gap between rolling element and rolling element, increased the number of rolling element, improved the bearing capacity of bearing, greatly extend the working life of bearing, solved problems of the prior art.
The utility model is to solve the problems of the technologies described above adopted technological scheme to be:
A kind of integrated cage formula single row roller bearing, comprise outer ring and inner ring, be provided with integrated retainer between outer ring and inner ring, be provided with several pocket holes along even circumferential on retainer, be respectively equipped with a rolling element in each pocket hole, central position, two ends at each rolling element is respectively equipped with a counterbore, be respectively equipped with a unthreaded hole at the retainer at each axial two ends, pocket hole middle part, each rolling element matches and is movably arranged in the pocket hole with unthreaded hole on retainer by being located at bearing pin in its two ends counterbore respectively.
The long side surface of each inboard, pocket hole is plane.
Be respectively equipped with a crescent shape groove on the retainer outer surface at each axial two ends, pocket hole.
Be respectively equipped with an outward-dipping tapered plane at the long side surface two ends of each inboard, pocket hole, at the two ends, short side of each inboard, pocket hole, be respectively equipped with a trapezoidal groove.
The utility model adopts such scheme, reasonable in design, to keep stand and retainer to cover integrated connection, and its pocket hole is changed and is made as square pocket keeping rack, the long side surface of inner both sides, pocket hole is plane, by bearing pin, rolling element is locked in the pocket hole of retainer, reduce the thickness of cage bar, dwindled the gap between rolling element and rolling element, increased the number of rolling element, improve the bearing capacity of bearing, greatly extended the working life of bearing.

Embodiment:
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and, in conjunction with its accompanying drawing, the utility model is elaborated.
As Figure 1-5, a kind of integrated cage formula single row roller bearing, comprise outer ring 1 and inner ring 2, be provided with integrated retainer 3 between outer ring 1 and inner ring 2, be provided with several pocket holes 4 along even circumferential on retainer 3, be respectively equipped with a rolling element 5 in each pocket hole 4, be respectively equipped with a counterbore 6 in the central position, two ends of each rolling element 5, retainer 3 middle parts at each 4 axial two ends, pocket hole are respectively equipped with a unthreaded hole 7, each rolling element 5 matches and is movably arranged in pocket hole 4 with unthreaded hole 7 on retainer 3 by being located at bearing pin 8 in its two ends counterbore 6 respectively.
The long side surface of each 4 inboard, pocket hole is plane.
Be respectively equipped with a crescent shape groove 9 on retainer 3 outer surfaces at each 4 axial two ends, pocket hole.It is interior to improve the lubrication effect of rolling element 5 end faces that crescent shaped groove 9 can make Lubricants more easily enter pocket hole 4, alleviated the weight of retainer 3 simultaneously, thereby reduced manufacture cost.
Be respectively equipped with an outward-dipping tapered plane 10 at the long side surface two ends of each 4 inboard, pocket hole, at the two ends, short side of each 4 inboard, pocket hole, be respectively equipped with a trapezoidal groove 11.Increase the storage area of pocket hole 4 internal lubrication oil, thereby effectively improved the lubrication effect of 4 inside, pocket hole.
Adopt integrated cage formula single row roller bearing of the present utility model, reasonable in design, to keep stand and retainer to cover integrated connection, and its pocket hole 4 is changed and is made as square pocket keeping rack, the long side surface of 4 inner both sides, pocket hole is plane, by bearing pin 8, rolling element 5 is locked in the pocket hole 4 of retainer 3, reduced the thickness of retainer 3 beams, dwindled the gap between rolling element 5 and rolling element 5, increased the number of rolling element 5, improve the bearing capacity of bearing, greatly extended the working life of bearing.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
