Abstract
The utility model relates to a retainer for a cylindrical roller bearing, which comprises an end cap, a pocket hole over beam and a bottom cap, wherein an integral retainer structure is formed by the end cap, the bottom cap of which the inner diameter and the outer diameter are the same as those of the bottom cap, and the pocket hole over beam of which both end sides are fixed on the inner sides of the end cap and the bottom cap. The outer diameter of the pocket hole over beam is smaller than the inner diameters of the end cap and the bottom cap, and locking surfaces which are mutually parallel are arranged between guide inclined surfaces at both sides of the pocket hole over beam and the outer wall of the pocket hole over beam. The utility model has the characteristics of the processing is simple and the size of a locking opening is easy to control.
Description
Technical field
The utility model relates to a kind of retainer, especially relates to a kind of cylinder roller bearing retainer.
Background technique
At present, for the Cuprum alloy solid bearing cage, a kind of structure is a split-type structural, and pocket hole lintel, end cap and bottom are processed respectively, will be riveted on end cap and the bottom by pocket hole lintel; Perhaps bottom and pocket hole lintel are made one, end cap is riveted on the lintel of pocket hole again and constitutes retainer.The retainer of this structure is complex process not only, and since part cumulative error of producing in processing and installation process not only reduce the precision of bearing, but also can influence usability.And the solid cage of another kind of structure is an overall structure, be to adopt extrusion moulding, though the size in pocket hole and surface quality are improved, pocket hole lintel is arranged between end cap and the bottom, still there is processed complex in this structure, and especially the fore shaft size is difficult for the defective of maintenance.
Summary of the invention
The purpose of this utility model provides a kind of easy to process, the cylinder roller bearing retainer of fore shaft size easy to control.
The utility model is that the technological scheme that achieves the above object is: a kind of cylinder roller bearing retainer, comprise end cap, pocket hole lintel and bottom, the pocket hole lintel that end cap that inside and outside footpath is identical and bottom and both end sides are fixed on end cap and bottom inboard constitutes the integral cage structure, the external diameter of pocket hole lintel is provided with the locking face that ends that is parallel to each other less than the internal diameter of end cap and bottom between the lead-in chamfered of lintel both sides, pocket hole and its outer wall.
The utility model adopts the advantage after the technique scheme to be: the utility model is arranged on pocket hole lintel the inboard of end cap and bottom, and the external diameter of pocket hole lintel is less than the internal diameter of end cap and bottom, therefore can carry out machining to end cap, bottom and the pocket hole lintel of retainer, because mach number of times reduces, reduce the accumulation machining error of retainer, improved the precision and the usability of retainer.The utility model is owing to be provided with lead-in chamfered in the both sides of pocket hole lintel, can conveniently roller be pressed in the pocket hole, because of the locking face that ends on the lintel of pocket hole is parallel to each other, can not only reduce roller and end the locking face surface of contact, reduce the roller rotational resistance, and the parallel locking face that ends is convenient to processing and fore shaft size easy to control.The utility model is because there is certain clearance in the inclined-plane of roller and pocket hole lintel, when bearing in high speed operation, lubricant oil flows under action of centrifugal force between the lead-in chamfered of roller and pocket hole lintel, and the bearing lubrication condition is improved, and has improved the usability and the working life of bearing.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a sectional structure schematic representation of the present utility model.
Fig. 3 is the I place structure for amplifying schematic representation of Fig. 1.
Embodiment
Cylinder roller bearing retainer of the present utility model is seen shown in Fig. 1,2 to be made of end cap 1, pocket hole lintel 2 and bottom 3.End cap 1 of the present utility model is identical with bottom 3 inside and outside footpaths, and the both end sides of pocket hole lintel 2 then is fixed on end cap 1 and bottom 3 inboard formation integral cage structures, and the two ends of pocket hole lintel 2 maintain an equal level mutually with end cap 1 and bottom 3.See shown in Figure 3, the external diameter of pocket hole lintel 2 is less than the internal diameter of end cap 1 and bottom 3, be provided with the only locking face 2-2 that is parallel to each other between the lead-in chamfered 2-1 of lintel 2 both sides, pocket hole and its outer wall, should end the width of locking face 2-2 between 0.3mm-2mm, have chamfering between the outer wall of pocket hole lintel 2 and the lead-in chamfered 2-1, can be convenient to the inside and outside wall of pocket hole lintel 2 and lead-in chamfered 2-1 and end locking face 2-2 and carry out machining by above-mentioned structure.
