Abstract
A needle bearing of a retainer assembly comprises a retainer and needle rollers and is characterized in that the retainer is of an integrated annular structure, a needle locking groove is formed in the inner side of the retainer and is of an omega-shaped structure, the outer circumference of the retainer comprises a preset number of supporting parts, the supporting parts are of I-shaped structures, a needle groove is formed between the supporting frames, and the needle rollers are arranged in the needle groove; the retainer is simple in structure, and the omega-shaped needle locking grooves are matched with the step shafts of the rolling needles, so that the rolling needles are prevented from falling to the inner side and the outer side of the retainer in the radial direction.
Description
Technical Field
The utility model relates to a bearing especially relates to a holder subassembly bearing.
Background
Needle roller bearings are roller bearings with cylindrical rollers, which are both thin and long with respect to their diameter, and are called needle rollers. The bearing has high load bearing capacity despite its small cross section, and the needle roller bearing is provided with long and thin rollers, so that it has compact radial structure, and its inner diameter size and load capacity are the same as other bearing types, and its outer diameter is minimum, so that it is specially applicable to bearing structure whose radial installation size is limited. The needle bearing in the prior art has the advantages of complex structure, easy displacement of the needle roller, serious long-time working abrasion, influence on the service life of the needle bearing, reduction in stability and high maintenance cost.
Disclosure of Invention
In order to solve the problem, the utility model provides a holder subassembly bearing provides a simple structure, be difficult for falling the needle and the high bearing of stability. In order to achieve the above purpose, the utility model adopts the following technical scheme: the needle bearing of the retainer assembly comprises a retainer and needle rollers, wherein the retainer is of an integrated annular structure, needle locking grooves are formed in the inner side of the retainer and are of an omega-shaped structure, the outer circumference of the retainer comprises a preset number of supporting parts, the supporting parts are of I-shaped structures, needle grooves are formed between supporting frames, and the needle rollers are arranged in the needle grooves.
Furthermore, two ends of the needle roller are arranged to be of a step shaft structure, and the step shaft is connected with the needle locking groove in an interference fit mode.
Compared with the prior art, the utility model discloses following beneficial effect has: the retainer is simple in structure, and the omega-shaped needle locking grooves are matched with the step shafts of the rolling needles, so that the rolling needles are prevented from falling to the inner side and the outer side of the retainer in the radial direction.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
FIG. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic structural view of the cage;
FIG. 3 is a schematic structural view of a needle roller;
in the drawings: 1. the needle locking device comprises a retainer, 2, needle rollers, 3, needle locking grooves, 4, a supporting part, 5, needle roller grooves, 6 and a step shaft.
Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described with reference to fig. 1, fig. 2 and fig. 3 and the specific embodiments.
As shown in fig. 1, 2 and 3, the needle bearing of the cage assembly comprises a cage 1 and needle rollers 2, wherein the cage 1 is of an integrated annular structure, a needle locking groove 3 is formed in the inner side of the cage 1, the needle locking groove 3 is of an omega-shaped structure, the outer circumference of the cage 1 comprises a preset number of supporting parts 4, the supporting parts 4 are of an i-shaped structure, needle grooves 5 are formed between the supporting parts 4, and the needle rollers 2 are arranged in the needle grooves 5.
Further, the two ends of the needle roller 2 are arranged to be of a step shaft 6 structure, and the step shaft 6 is connected with the needle locking groove 3 in an interference fit mode.
Compared with the prior art, the utility model discloses following beneficial effect has: the retainer is simple in structure, and the omega-shaped needle locking grooves are matched with the step shafts of the rolling needles, so that the rolling needles are prevented from falling to the inner side and the outer side of the retainer in the radial direction.
Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
