Abstract
A bi-centric pocket cage of a cylindrical roller bearing comprises a cage seat and a cage end cover. The bi-centric pocket cage is technically characterized in that the cage seat is provided with a plurality of bi-centric pockets, a row of cylindrical rollers are mounted into a same row of pockets on the cage seat, and the cage end cover is firmly locked on the cage seat via a rivet. When using the cylindrical roller bearing with the bi-centric pocket cage, a second pocket is not functional, when in need of examining whether or not an outer ring fatigues, an operator lays the bearing horizontally, internally shifts the rollers and leads the same to withdraw into the second pocket, and the outer ring can be taken out smoothly for quality examination after being broken away from a rib, thereby improving use safety performance of the bearing and avoiding accidents.
Description
Technical field
The utility model relates to a kind of bearing part, particularly relates to a kind of cylinder roller bearing retainer.
Background technique
The retainer that roller bearing is commonly used comprises keeping stand and retainer end cap, and the retainer end cap is fixed on rivet and keeps on the stand, and roller is contained in the pocket hole that keeps on the stand, and in the raceway that constitutes by outer ring and inner ring of packing into.The pocket hole of at present known cylinder roller bearing retainer is monocentric, the shortcoming of this retainer is: this retainer is applied in the roller bearing of two outer ring structures, when being applied to large-scale key equipment, after bearing uses a period of time, can whether outer ring raceway be tired, continue to use and all can't know, unless retainer is destroyed, owing to can't know the quality condition that bearing outer ring is in operation, thereby cause bearing in application, to have potential safety hazard.
The model utility content
The purpose of this utility model provides the two pocket holes, center of a kind of roller bearing retainer, can conveniently the outer ring be taken out, and checks, thereby has improved the Safety performance that bearing uses.
The technological scheme that adopts is:
The two pocket holes, center of roller bearing retainer, comprise and keep stand and retainer end cap, its technological points is to keep stand to be provided with pocket hole, a plurality of pairs of centers, and the columna roller is packed into to be kept in the same row pocket hole on the stand retainer end cap being kept on the stand with rivet lock jail.
This roller bearing with pocket hole, two center retainer in use, second pocket hole is inoperative, when needs check that the outer ring is whether tired, after bearing kept flat, to move in the roller, roller is retracted in second pocket hole, behind the disengaging rib, the outer ring just can be taken out smoothly, carries out quality inspection.Thereby improved the Safety performance that bearing uses, avoided security incident to take place.
Description of drawings
Fig. 1 is an a kind of embodiment's of the present utility model structural representation.
Fig. 2 is the roller bearing schematic representation that pocket hole, of the present utility model pair of center retainer is housed.
Embodiment
The two pocket holes, center of roller bearing retainer comprises keeping stand 1 and retainer end cap 2 that retainer end cap 2 is fixedlyed connected with keeping stand 1 by rivet 3, and its technical characterstic is: keep on the stand 1 pocket hole, a plurality of pairs of centers 4 being arranged.Each two pocket hole 4, center is that first single pocket hole 5 and the radius of R is R by radius
1Second single pocket hole 6 constitute described radius R≤radius R
