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, adduction groove 5, stretch into supporting section 6, outside fix section 7, seal ring root 8, axial seal lip 9, radial seal lip 10, thin segment 11, bent plate spring 12, C shape support spring coil 13.
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, the ultra-thin ball bearing of a kind of single-side sealing, comprise bearing outer ring 1, bearing inner race 2, bearing outside diameter is 10 to 30 with the ratio of bearing width, also comprise retainer 3, described bearing outer ring is provided with multiple outer pocket groove, ball 4 is provided with in described outer pocket groove, described bearing inner race be provided with multiple corresponding with ball in pocket groove, on described bearing outer ring, bearing inner race is provided with adduction groove 5, described retainer comprises and stretches into supporting section 6, outside fix section 7, the described supporting section that stretches into stretches between bearing outer ring and bearing inner race, described outside fix section two ends are in the adduction groove on bearing outer ring respectively, within adduction groove scope on bearing inner race, described outside fix section two ends are respectively provided with caulking groove in a sealing, between described outside fix section and bearing outer ring, sealing configuration is provided with between outside fix section and bearing inner race, described sealing configuration comprises and is stuck in seal ring root 8 in sealing in caulking groove and axial seal lip 9, radial seal lip 10, described axial seal lip, the contacting part of radial seal lip and bearing is procheilon edge, the length ratio of axial two end faces of described ball distance between bearing is 1.2 to 2.
Overall relative thickness is thin, so the installation space of retainer is limited, in the present invention, ball is set to offset, the length ratio making axial two end faces of ball distance between bearing is 1.2 to 2, thus can at one end for retainer leaves more space, improve the thickness of retainer, thus improve bearing integral intensity, the upper outside positioning section two ends of retainer are located within the adduction groove on bearing outer ring, the adduction groove on bearing inner race respectively, and the outside fix section that make use of retainer is as a part of position structure, improve overall relevance and support effect.Have double-sealing bead structure, two different surfaces form potted line, and two sealing lips are connected on a seal ring root, have stressed relevance when compressing mutually, bulk strength and sealing effect can be protected.
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 radial seal lip forms thin segment 11 near seal ring root place indent, the inner side of described thin segment is provided with some lines of rabbet joint, described axial seal lip is provided with some lines of rabbet joint, and described sealing configuration also comprises some bent plate springs 12, and the two ends of each bent plate spring are inserted in each line of rabbet joint on thin segment, on axial seal lip respectively.Described sealing configuration also comprises some C shapes and supports spring coil 13, the raised section of C shape support spring coil is supported on the back of radial seal lip, the two ends of C shape support spring coil withstand sidewall, the diapire of adduction groove residing for self respectively, the number that described C shape supports spring coil is consistent with bent plate spring number, and the raised section correspondence that each C shape supports spring coil contacts with the raised section of a bent plate spring.
When outside fluid impact sealing configuration, the most easily there is displacement and distortion in procheilon edge, and remaining part is more because thickness is greater than procheilon edge relatively, then not yielding, the present embodiment, by arranging thin segment, makes thin segment place also easy pressurized indent, and the existence of bent plate spring, then can make up the intensity of thin segment disappearance, thus make to divide when not affecting bulk strength to dissipate the deformation force that procheilon edge is subject to.Further, bent plate spring can be oppressed axial seal lip and is better adjacent to surface of contact, so, even if radial direction seal ring lost efficacy, also can better play the effect that two roads seal.C shape supports the existence of spring coil, directly can be formed radial sealing lip and support, and the compressing of bent plate spring raised section can be subject to and outer is out of shape, thus play radial seal lip compression effect on the contact surface, and, support fixing, the support effect of spring coil to increase C shape, the part that C shape can also be supported spring coil raised section snaps in radial seal lip or is connected with radial seal lip.
