Description
Technical field
The present invention relates to a kind of reinforced bearing plastic-steel retainer, belong to bearing applied technical field.
Background technique
At bearing load with under vibrating larger operating mode, the mechanical property quality of retainer can not only have influence on stability and the reliability of bearing operation, and directly can have influence on the life-span of bearing.If retainer easily damages in use, so just can lose the effect of separating rolling element, cause bearing normally not work.
Existing bearing plastic-steel retainer generally adopts the molding and forming of fiberglass reinforced type engineering plastics, relative to conventional steel retainer and copper cage, have lightweight, manufacturing efficiency is high, use the advantages such as safer, but the shortcoming of this plastic-steel retainer is that intensity is lower.The intensity of conventional steel retainer and copper cage exceeds more than 2 times than existing plastic-steel retainer, and therefore, the Fracture Probability that existing plastic-steel retainer causes due to vibratory impulse etc. in compared with using process under bad working environments is greater than steel retainer and copper cage.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of reinforced bearing plastic-steel retainer that can improve tensile strength and flexural strength.
For achieving the above object, the present invention takes following technological scheme: a kind of reinforced bearing plastic-steel retainer, and it is characterized in that: it comprises a retainer body, described retainer body comprises the window beam of collar tie beam described in two collar tie beams and multiple connection two; The skeleton of a ring-type is embedded respectively in two collar tie beams.
Described in two, the diameter of collar tie beam is unequal.
The equal diameters of collar tie beam described in two.
Described in each, skeleton connects multiple centering ear arranged at equal intervals near the side of the exterior edge face of collar tie beam described in its place.
Feel relieved described in each exterior edge face of ear is concordant with the exterior edge face of collar tie beam described in each.
The cross section of skeleton described in each adopts "T"-shaped, one of " L " shape and " one " font.
Skeleton described in each adopts tensile strength to be greater than the metallic material of 200MPa or fusing point to be shaped by stamping process higher than the enhanced engineering plastics of 200 DEG C.
Skeleton described in each is arranged at intervals with multiple fenestra.
The present invention is owing to taking above technological scheme, it has the following advantages: 1, the present invention owing to embedded in two skeletons respectively in two collar tie beams of retainer body, the tensile strength in retainer working state lower stress direction is significantly improved, retainer radial dimension also can be made more stable relative to temperature variation simultaneously.2, the present invention due to adopt single injection-molded, therefore self lubricity of the present invention, friction factor is low, inertia is little.3, the present invention is owing to being arranged at intervals with multiple fenestra at each skeleton, adds the conjugation of two skeletons and plastic body.4, conventional steel retainer and plastic cage are had complementary advantages by the present invention, and overall performance significantly promotes.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
The present invention proposes a kind of reinforced bearing plastic-steel retainer, as shown in figures 1-4, it comprises a retainer body 1, retainer body 1 comprises the window beam 3 of two collar tie beams 2 and multiple connection two collar tie beam 2, wherein, the diameter of two collar tie beams 2 unequally (now can form tapered roller bearing retainer, as shown in Figure 1 and Figure 2), also equally (now cylinder roller bearing retainer can be formed, as shown in Figure 3, Figure 4).The skeleton 4 of a ring-type is embedded respectively in two collar tie beams 2.
In above-described embodiment, each skeleton 4 connects multiple centering ear 5 (as Suo Shi Fig. 5 ~ 10) arranged at equal intervals near the side of the exterior edge face of its place collar tie beam 2, before retainer body 1 is shaping, centering ear 5 fixes with bearing plastic-steel retainer mould (not shown).
In above-described embodiment, the exterior edge face of each centering ear 5 can stretch out the exterior edge face (exposed centering ear) (as Suo Shi Fig. 5 ~ 7) of each collar tie beam 2 respectively, and after molding and forming, secondary operations removes the outer centering ear portions spilling two collar tie beam 2 exterior edge faces.Or the exterior edge face concordant with the exterior edge face of each collar tie beam 2 (concealed centering ear) (as shown in figs. 8-10) of each centering ear 5, direct molding and forming.
In above-described embodiment, the cross section of each skeleton 4 can adopt the various ways such as "T"-shaped, " L " shape, " one " font.
In above-described embodiment, each skeleton 4 can adopt tensile strength to be greater than the metallic material of 200MPa or fusing point to be shaped by stamping process higher than the enhanced engineering plastics of 200 DEG C.
In above-described embodiment, multiple fenestra can be arranged at intervals with on each skeleton 4, when molding and forming of the present invention, the combination degree of skeleton 4 and plastic body can be increased.
When the present invention manufactures, first manufacture a plastic steel shaft and accept insurance and hold frame mould and two skeletons 4, and multiple centering ear 5, each skeleton 4 is connected with multiple centering ear 5.Then control plastic steel shaft to accept insurance and hold frame mould and fix multiple centering ear 5, support two skeletons 4 by multiple centering ear 5 and be positioned at plastic steel shaft and accept insurance and hold two collar tie beams 2 of frame mould inner chamber.By plastic-steel retainer single injection-molded, if adopt exposed centering ear, then need shaping after again secondary operations remove and stretch out the part of end face.
The various embodiments described above are only for illustration of the present invention, and wherein the structure, Placement etc. of each parts all can change to some extent, and every equivalents of carrying out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
