Abstract
The utility model relates to a novel nylon retainer structure which comprises a retainer. The novel nylon retainer structure is characterized in that the retainer is provided with two lines of pockets which are crossed and distributed left and right on the circumference of a pitch circle evenly. The utility model has the advantages that the novel nylon retainer structure adopts a two-line integral body mode, saves the space of the wall thickness of two retainers and a gap between the two retainers, causes the minimum limit of the spherical center distance of two lines of balls of bearings to be reduced further, and is especially suitable for narrow two-line angular contact ball bearings with large radial wall thickness; the weight ratio of the retainer reduces nearly 15 percent than even before (the raw material is saved), and the production cost is lowered; meanwhile, under the condition of same structure and space, the diameter of steel balls can be enlarged by one specification, the rated load of the bearings is improved by about 30 percent, and the mean life of the bearings under the same using condition is prolonged by about 20 percent.
Description
Technical field
The utility model relates to a kind of retainer of novel double-row angular contact bal bearing, particularly a kind of nylon cages of novel overall formula structure.
Background technique
Usually the structure of double-row angular contact bal bearing retainer is two independent retainers, double-row angular contact bal bearing, the least limit of the centre of sphere distance of two row balls is subjected to the restriction in retainer wall thickness and gap thereof, the narrow bearing of the big bearing width of radial thickness is when design, if when adopting two independent retainers (shown in Figure 1) because the restriction of axial space, can only adopt the steel ball than small dimension, its shortcoming: the rated load of bearing is low, and reliability is low.
Summary of the invention
The purpose of this utility model is to solve two independent retainers of double-row angular contact bal bearing retainer employing in the prior art, because the restriction of axial space, can only adopt than the existing the problems referred to above of the steel ball of small dimension, the nylon cages of novel overall formula structure is provided.The nylon cages structure that the utility model design is novel comprises retainer, it is characterized in that: biserial pocket hole is arranged, staggered being distributed on the pitch circle circumference about two row pocket holes on the retainer.The utility model has the advantages that the biserial integrated type, saved the space of two retainer wall thickness and intermediate space, the least limit of the centre of sphere distance of bearing two row balls further reduced, be specially adapted to the big narrow serial double-row angular contact bal bearing of radial thickness; The weight ratio of retainer reduced nearly 15% (having saved raw material) in the past and had also reduced simultaneously cost of production simultaneously; And under same structure space condition, steel ball size can strengthen a specification, and the load rating of bearing improves about 30%, has prolonged about 20% in the average life of identical service condition lower bearing.
Description of drawings
Accompanying drawing 1 is the prior art constructions schematic representation,
Accompanying drawing 2 is a structural representation of the present utility model,
Accompanying drawing 3 is a local structure for amplifying schematic representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
Comprise retainer 1 among Fig. 2,3, it is characterized in that: 2, two row pocket holes, biserial pocket hole about 2 staggered being distributed on the pitch circle circumference are arranged on the retainer 1.Because two row pocket holes about 2 staggered being distributed on the pitch circle circumference on the retainer 1, saved the space of two retainer 1 wall thickness and intermediate space, the least limit of the centre of sphere distance of bearing two row balls is further reduced, be specially adapted to the big narrow serial double-row angular contact bal bearing of radial thickness; The weight ratio of retainer 1 reduced nearly 15% (having saved raw material) in the past and had also reduced simultaneously cost of production simultaneously; And under same structure space condition, steel ball size can strengthen a specification, and the load rating of bearing improves about 30%, has prolonged about 20% in the average life of identical service condition lower bearing.
Claims (1)
1, novel nylon cages structure comprises retainer, it is characterized in that: biserial pocket hole is arranged, staggered being distributed on the pitch circle circumference about two row pocket holes on the retainer.
