The utility model is to overcome deficiency of the prior art, provides a kind of reasonable integral structure, effectively can ensure the intensity of whole sealing configuration, there will not be constructive interference, can maintain the ultra-thin bearing structure of excellent sealing effect in working procedure.
To achieve these goals, the utility model is by the following technical solutions:
A kind of ultra-thin bearing structure, comprises bearing outer ring, bearing inner race, retainer, described bearing outer ring is provided with multiple outer pocket groove, is provided with ball in described outer pocket groove, described bearing inner race be provided with multiple corresponding with ball in pocket groove, described retainer is provided with and ball number, the ball pocket groove that position is corresponding, also comprise the sealing configuration that two are in bearing two end faces respectively, described sealing configuration comprises oil sealing, be located at the external sealed groove on bearing outer ring, be located at the interior seal groove on bearing inner race, described oil sealing comprises joint, stretch into the C shape sealing lip in external sealed groove and a fitted seal portion, described fitted seal portion comprises outer top lip, radial seal lip, adduction lip, described radial seal lip coordinates with interior seal groove, described adduction lip, outer top lip and bearing inner race are affixed, and described joint comprises thin adhesive layer, tinsel skeleton, described thin adhesive layer and C shape sealing lip, fitted seal portion is formed in one structure, and described tinsel skeleton to be located on thin adhesive layer and to be connected with thin adhesive layer.
As preferably, described tinsel skeleton is connected to thin adhesive layer towards on the surface of ball side, described tinsel skeleton edges is embedded in thin adhesive layer, and described retainer is provided with multiple ball groove, is provided with the steel ball for contacting with tinsel skeleton in described ball groove.
As preferably, described retainer comprises multiple bag pearl cover for spacing ball, connects the female connector portion of bag pearl cover, described ball groove is in Bao Zhu and puts, each Bao Zhu puts has at least four ball grooves, Bao Zhu puts half ball channel opening towards a sealing configuration, all the other ball grooves are towards another sealing configuration, and the upper shed of a bag pearl cover is uniformly distributed centered by this bag pearl cover axis towards all ball grooves of same sealing configuration.
As preferably, described steel ball is 1 to 5mm apart from contiguous tinsel skeleton distance.
The beneficial effects of the utility model are: sealing configuration has tinsel skeleton, and intensity is high, strong shock resistance; Steel ball can play the effect of protection; prevent tinsel framework deformation excessive and cause C shape sealing lip, fitted seal portion sealing loosen; and; rolling friction between steel ball and tinsel skeleton; frictional force is little, can not affect work, but can provide effective support for the tinsel skeleton moment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the structural representation of the utility model embodiment 2.
In figure: bearing outer ring 1, bearing inner race 2, retainer 3, ball 4, oil sealing 5, external sealed groove 6, C shape sealing lip 7, fitted seal portion 8, outer top lip 9, radial seal lip 10, adduction lip 11, thin adhesive layer 12, tinsel skeleton 13, steel ball 14, bag pearl cover 15.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Embodiment 1: as Fig. 1, in embodiment shown in Fig. 2, a kind of ultra-thin bearing structure, comprises bearing outer ring 1, bearing inner race 2, retainer 3, described bearing outer ring is provided with multiple outer pocket groove, is provided with ball 4 in described outer pocket groove, described bearing inner race be provided with multiple corresponding with ball in pocket groove, described retainer is provided with and ball number, the ball pocket groove that position is corresponding, also comprise the sealing configuration that two are in bearing two end faces respectively, described sealing configuration comprises oil sealing 5, be located at the external sealed groove 6 on bearing outer ring, be located at the interior seal groove on bearing inner race, described oil sealing comprises joint, stretch into the C shape sealing lip 7 in external sealed groove and a fitted seal portion 8, described fitted seal portion comprises outer top lip 9, radial seal lip 10, adduction lip 11, described radial seal lip coordinates with interior seal groove, described adduction lip, outer top lip and bearing inner race are affixed, and described joint comprises thin adhesive layer 12, tinsel skeleton 13, described thin adhesive layer and C shape sealing lip, fitted seal portion is formed in one structure, and described tinsel skeleton to be located on thin adhesive layer and to be connected with thin adhesive layer.
In general, bearing is all that static load is born in outer ring, inner ring bears dynamic load, can fully ensure to seal so bearing outer ring coordinates with C shape sealing lip, and the fitted seal portion of more complicated is provided with at bearing inner race, fitted seal portion comprises outer top lip, radial seal lip, adduction lip, radial seal lip coordinates with interior seal groove, mainly play the effect of location sealing, make it and bearing inner race relatively rotates time not easily deviate from bearing inner race, and adduction lip, outer top lip then provides two sealings on bearing thickness direction, thus ensure good " motive sealing " effect.And C shape sealing lip, to be connected by thin adhesive layer between fitted seal portion, thickness greatly reduces, thus can avoid directly contacting with retainer, by tinsel skeleton maintain thin adhesive layer intensity and and C shape sealing lip, connection effect between fitted seal portion, not only make joint thickness subtract greatly, intensity wins in the past especially.The non-deformability be subject to when external fluid is impacted also gets a promotion, and bearing outer ring, sealing between bearing inner race have sufficient guarantee.
Embodiment 2: the basic structure of the present embodiment and mode of execution are with embodiment 1, its difference is, as shown in Figure 3, described tinsel skeleton is connected to thin adhesive layer towards on the surface of ball side, described tinsel skeleton edges is embedded in thin adhesive layer, described retainer is provided with multiple ball groove, is provided with the steel ball 14 for contacting with tinsel skeleton in described ball groove.Described retainer comprises multiple bag pearl for spacing ball cover 15, connects the female connector portion of bag pearl cover, described ball groove is in Bao Zhu and puts, each Bao Zhu puts has at least four ball grooves, Bao Zhu puts half ball channel opening towards a sealing configuration, all the other ball grooves are towards another sealing configuration, and the upper shed of a bag pearl cover is uniformly distributed centered by this bag pearl cover axis towards all ball grooves of same sealing configuration.Described steel ball is 1 to 5mm apart from contiguous tinsel skeleton distance.
Steel ball has fine pitch with tinsel skeleton at ordinary times; during bearing working; because outside has the compressing of fluid; self can be given a shock again; so tinsel skeleton can bend and be out of shape; now will be withstood by steel ball; steel ball can play the effect of protection; prevent tinsel framework deformation excessive and cause C shape sealing lip, fitted seal portion sealing loosen; and; be rolling friction between steel ball and tinsel skeleton, frictional force is little, can not work be affected, but effective support can be provided for the tinsel skeleton moment.
