Abstract
The utility model relates to a split type retainer aligning roller bearing. According to the technical scheme provided by the utility model, the split type retainer aligning roller bearing comprises an internal ring, an external ring, a retainer positioned between the internal ring and the external ring, and a plurality of spherical rollers uniformly arranged on the retainer, and is characterized in that the retainer has a split type structure so as to be split into two similar parts, and the plurality of spherical rollers are uniformly distributed on the two retainers. The split type retainer aligning roller bearing has the following advantages that (1) the split copper retainer with excellent performance is adopted so as to enable the two rows of rollers to be not interfered in running, and enable the copper retainer not to be applied by external impact force in running, so that the service life of the bearing is prolonged; (2) by adopting the internal ring without a fixed middle baffle edge, the bearing enables the length of the rollers to be long, and the bearing capacity of the bearing is strong, thus being more beneficial to prolonging the service life of the bearing under the same load conditions; and (3) other parts of the bearing have good universality, thus having easy production and management.
Description
Technical field
The utility model relates to a kind of selfaligning roller bearing, especially a kind of split type retainer selfaligning roller bearing.
Background technique
Existing roller bearing structure has two kinds, and a kind of bearing inside is to adopt the global copper retainer, this airframe bearing by copper cage 9, the outer ring 6 of integral body, have fixing little rib 15 not have that fixedly the inner ring 7 and the spherical roller 8 of centre rib constitute.This structure causes global copper retainer 9 to be subjected to extra impact force in the running owing to be the mutual interference of global copper retainer 9, two row rolling elements when running phase, and retainer 9 is easy to damage, and makes bearing early failue, and the life-span is shorter.
Another kind of roller bearing inside is to adopt the split copper cage, this airframe bearing by copper cage 12, the outer ring 10 of split, the inner ring 13 and the spherical roller 14 of centre rib 11 constitute to have fixing little rib to have fixedly.This bearing makes the length of roller 14 short because inner ring has fixedly centre rib 11, and the bearing capacity of bearing is poor, and the following life-span of condition of equal load is short.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the split type retainer selfaligning roller bearing of a kind of highly versatile, function admirable is provided.
According to the technological scheme that the utility model provides, described split type retainer selfaligning roller bearing, comprise inner ring, outer ring and be positioned at inner ring and the outer ring between retainer and evenly be arranged at several sphere rollers on the retainer; It is characterized in that: described retainer is a split-type structural, makes described retainer be divided into similar two, and several sphere rollers are distributed evenly on two retainers.
The outer rim both sides of described inner ring are provided with rib; Described rib extends radially outwardly along inner ring.The inwall of described outer ring is concave arc shape on the axial section of described bearing, the middle part diameter of inwall that makes described outer ring is greater than the both sides diameter of the inwall of outer ring.The outer wall of described inner ring is outstanding shape on the axial section of described bearing, the middle part diameter of outer wall that makes described inner ring is greater than the both sides diameter of the outer wall of described inner ring.
The utlity model has following advantage: (1) adopts function admirable split copper cage, and two row rolling elements are not disturbed in the running mutually, makes copper cage not be subjected to extra impact force in the running, prolongs bearing life.(2) bearing is used in inner ring does not have fixedly centre rib, makes the length of roller long, and the bearing capacity of bearing is strong, more helps prolonging bearing life under the condition of equal load.(3) other component universalities of this bearing are good, and production management is easy.

Fig. 2 is the structural representation of prior art integral cage roller bearing.
Fig. 3 is the structural representation of the split type retainer roller bearing of prior art.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1: described split type retainer selfaligning roller bearing comprises inner ring 3, outer ring 2 and is positioned at inner ring 3 and the retainer 1 of 2 of outer rings and evenly be arranged at several sphere rollers 4 on the retainer 1; It is characterized in that: described retainer 1 is split-type structural, makes described retainer 1 be divided into similar two, and several sphere rollers 4 are distributed evenly on two retainers.
The outer rim both sides of described inner ring 3 are provided with rib 5; Described rib 5 extending radially outwardly along inner ring 3.The inwall of described outer ring 2 is concave arc shape on the axial section of described bearing, the middle part diameter of inwall that makes described outer ring 2 is greater than the both sides diameter of the inwall of outer ring 2.The outer wall of described inner ring 3 is outstanding shape on the axial section of described bearing, the middle part diameter of outer wall that makes described inner ring 3 is greater than the both sides diameter of the outer wall of described inner ring 3.Described retainer 1 adopts copper cage.
The inner ring 3 that roller bearing described in the utility model adopts does not have fixedly centre rib, makes the length of spherical roller 4 long, and the bearing capacity of bearing is strong, more helps prolonging bearing life under the condition of equal load, in the running function admirable.Split type copper cage 1 does not disturb two row spherical rollers in the running mutually, makes copper cage 1 not be subjected to extra impact force in the running, prolongs bearing life.This structure improves the bearing capacity of bearing, the adaptive capacity of enhancing retainer 1, the life-span of improving bearing by the improvement design to retainer 1, inner ring 3.
