Abstract
A comb-shaped cage with double-center-distance pockets for bearings is cylindrical. Comb teeth are circumferentially arrayed on end surfaces on two sides of the comb-shaped cage, work pockets for holding rollers are arranged among the comb teeth and are circumferentially arrayed, and center distances of the work pockets are equal to diameters of the rollers rotating along an axle center. The key of the technical scheme includes that under a condition of remaining the position of a work pocket of the existing comb-shaped cage unchanged, an assembly pocket is further bored after slightly shifting on the position of the existing work pocket approaching the center of the cage, and the assembly pocket is only used for assembling the rollers. The comb-shaped cage with double-center-distance pockets for bearings has the advantages that the assembly pockets are bored on the inner sides of work pockets of the comb-shaped cage, and then the rollers can enter the work pockets through the assemblypockets, thereby not only bringing convenience for bearing assembly, but also eliminating gaps for mounting the rollers on ribs of roller ways of outer rings of the bearings, and enabling operation of the bearings to be safer and more reliable.
Description
Technical field
The utility model relates to the roller-mill bearing technical field, particularly a kind of bearing pectination retainer that has two centre distance pocket holes.
Background technique
At present, existing multiple row roller bearing (seeing shown in Figure 1), it is made up of inner ring 1, outer ring 4, multiple row roller 2 and pectination retainer 3.Pectination retainer both ends of the surface have and the same number of work pocket of bearing one row roller hole 6, and work pocket hole centre distance 5 is measure-alike with the pitch circle of circumferential arrangement roller.During bearing operation, the broach 7 of pectination retainer 3 separates roller 2, avoids the direct friction between the roller to give birth to heat, to improve the limit speed of bearing.
The pectination retainer is mainly used in the multiple row roller bearing, and two end faces of pectination retainer have the equidistant work pocket hole along circumferential arrangement, and roller is deposited in this work pocket hole, and roller is separated.The same row roller of work pocket hole number quantity; The equal diameters (the pectination retainer is seen Fig. 2, Fig. 3) that work pocket hole centre distance and bearing roller rotate along the axle center:
During the bearing assembling, not only roller to be put into the outer ring raceway of bearing, also will put in the work pocket hole of retainer.But existing pectination retainer has tangible inconvenience when bearing is assembled, promptly bearing outer ring ball track has rib, and roller can not directly be put in the work pocket hole of outer raceway of bearing and retainer simultaneously.In order to solve the assembly problem of existing bearing, it is the breach 8 of producing a dress roller on the rib with bearing outer ring ball track, during assembling retainer is put into raceway position, the breach of the dress roller of outer ring is aimed in work pocket hole, a roller is pressed in the work pocket hole of retainer by breach, and the roller of working has simultaneously also entered outer ring raceway.Rotate retainer then and aim at the breach of adorning roller, like this, packed in ground of roller, finish the assembling (seeing shown in Figure 4) of bearing by next work pocket hole.
Because bearing outer ring leaves the breach of assembling, bearing raceway rib in the running is discontinuous to the guiding of roller end face, has roller to turn to the jammed danger of indentation, there.Make that bearing can not safe handling.
The model utility content
The purpose of this utility model provides a kind of bearing pectination retainer that has two centre distance pocket holes, it has not only solved the inconvenience of bearing fit on, the more important thing is the breach of having cancelled the dress roller on the bearing outer ring ball track rib, the outer ring raceway rib can guide continuously to roller like this, has guaranteed the running safety of bearing.
For achieving the above object, the utility model adopts following design proposal:
A kind of bearing pectination retainer that has two centre distance pocket holes, it is cylindric, have along circumferential row at the both sides of pectination retainer end face and to show broach, the work pocket hole that ccontaining roller is arranged between broach, this work pocket hole is along circumferential arrangement, and work pocket hole centre distance and roller are along the equal diameters of axle center rotation;
Inboard boring has assembling pocket hole in described work pocket hole, and this assembling pocket hole is along circumferential arrangement, and this assembles pocket hole centre distance less than work pocket hole centre distance, the inboard opening size in this assembling pocket hole and the equal diameters in work pocket hole.
In the end face of the both sides of pectination retainer, show assembling pocket hole along circumferential row.
Described assembling pocket hole centre distance is less than work pocket hole centre distance 6～12mm.
The technical program is under the constant situation in the work pocket hole site of original pectination retainer, near on the position at retainer center, does displacement boring one assembling pocket hole once more in original work pocket hole slightly, and assembling roller usefulness is only done in this assembling pocket hole.
The beneficial effects of the utility model are: owing in the inboard boring in the work pocket hole of pectination retainer assembling pocket hole is arranged, roller can be entered in the work pocket hole by work pocket hole, both be convenient to the bearing assembling, eliminate the breach of the dress roller on the bearing outer ring ball track rib again, made bearing operation more safe and reliable.

Embodiment
Referring to Fig. 5, Fig. 6, shown in Figure 7: a kind of bearing is with the pectination retainer that has two centre distance pocket holes, it is cylindric, have along circumferential row at the both sides of pectination retainer 3 end face and to show broach 7, the work pocket hole 6 that ccontaining roller is arranged between broach 7, this work pocket hole 6 is along circumferential arrangement, and work pocket hole centre distance 5 and roller are along the equal diameters of axle center rotation;
In the 6 inboard borings of described work pocket hole assembling pocket hole 10 is arranged, this assembling pocket hole 10 is along circumferential arrangement, and this assembling pocket hole centre distance 9 is less than work pocket hole centre distance 5, and this assembles interior side opening 11 sizes in pocket hole 10 and the equal diameters in work pocket hole 6.
For easy to assembly and satisfy matching requirements, in the end face of the both sides of pectination retainer, show assembling pocket hole 10 along circumferential row.
Described assembling pocket hole centre distance 9 is 6～12mm less than the distance of work pocket hole centre distance 5.
The main points of the technical program are under the constant situation in the work pocket hole site of original pectination retainer, near on the position at retainer center, do displacement boring one assembling pocket hole 10 once more in original work pocket hole slightly, and assembling roller usefulness is only done in this assembling pocket hole.During assembling, the roller of bearing enters in the work pocket hole 6 by assembling pocket hole 10, has cancelled the breach that bearing outer ring leaves assembling, has made things convenient for assembling, has also improved the safety in utilization of bearing.
