Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail each embodiment of the present invention with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a bearing retainer, as shown in fig. 1 and 2, including: the upper frame body 1 and the lower frame body 2 are arranged opposite to each other along the direction of a preset axis. Wherein, the upper frame body 1 has a plurality of equidistant upper bending sections 11 annularly arranged around the preset axis direction, and an upper horizontal section 12 is arranged between every two adjacent upper bending sections 11. Meanwhile, the lower frame body 2 is provided with a plurality of lower bending sections 21 annularly arranged at equal intervals around the preset axis direction, and a lower horizontal section 22 is arranged between every two adjacent lower bending sections 21. In the present embodiment, the number of the upper bent segments 11 and the number of the lower bent segments 21 are the same and are uniquely corresponding to each other, and each of the upper bent segments 11 and the uniquely corresponding lower bent segment 21 together enclose the housing space 6 for housing the rolling elements 3 of the bearing.
In the present embodiment, as shown in fig. 2 and 3, the number of the upper horizontal segments 12 is the same as that of the lower horizontal segments 22, and the upper horizontal segments 12 and the lower horizontal segments 22 are uniquely corresponding to each other, the positioning grooves 13 are respectively formed on one side of each upper horizontal segment 12 corresponding to the uniquely corresponding lower horizontal segment 22, the positioning blocks 23 are respectively provided on one side of each lower horizontal segment 22 corresponding to the uniquely corresponding upper horizontal segment 12, and the positioning blocks 23 on each lower horizontal segment 22 are respectively fitted in the positioning grooves 13 of the uniquely corresponding upper horizontal segment 12.
It can be seen from the above that, since the positioning grooves 13 are respectively formed on one side of each upper horizontal segment 12 of the upper frame body 1 of the retainer corresponding to each lower horizontal segment 22 uniquely corresponding to the lower frame body 2, and meanwhile, the positioning blocks 23 are respectively arranged on one side of each lower horizontal segment 22 of the lower frame body 2 corresponding to each upper horizontal segment 12 uniquely corresponding to the upper frame body 1, when the upper frame body 1 and the lower frame body 2 are assembled, the upper frame body 1 and the lower frame body 2 can be quickly positioned during assembly through the cooperation of each positioning block 23 and each positioning groove 13, and each rolling element is ensured to have better rolling performance in the accommodating space 6 surrounded by each upper bending segment 11 and each lower bending segment 21 uniquely corresponding to each rolling element, so that the bearing can avoid abnormal mechanical wear during use, thereby prolonging the service life of the bearing.
Specifically, as shown in fig. 2 and 3, in the upper frame 1, the positioning grooves 13 are all tapered grooves, the inner diameters of the tapered grooves are gradually increased from the groove bottom 131 to the groove opening 132, the positioning blocks 23 are all tapered blocks, and the tapered surfaces 231 of the tapered blocks are fitted with the groove walls 133 of the tapered grooves. By means of the matching of the conical block and the conical groove, the upper frame body 1 and the lower frame body 2 can realize self-guiding during assembly, and therefore the assembly precision between the upper frame body 1 and the lower frame body 2 is further improved.
In addition, as shown in fig. 4, preferably, the magnetic layer 4 is disposed on the bottom 131 of each positioning groove 13, and each positioning block 23 is a magnetic block with a polarity opposite to that of the magnetic layer 4, so that the magnetic attraction between the upper frame body 1 and the lower frame body 2 can be realized when each positioning block 23 on the lower frame body 2 is embedded into each positioning groove 13 of the upper frame body 1, thereby further facilitating the assembly between the upper frame body 1 and the lower frame body 2. In the present embodiment, the magnetic layer 4 is a magnetic sheet fixed to the bottom of the groove bottom 131 of the positioning groove 13, but it is needless to say that the groove bottom 131 of the positioning groove 13 may be directly used as a magnetic layer for attracting the positioning block 23 in actual use.
Note that, in the present embodiment, as shown in fig. 4, the side of each upper bent segment 11 with respect to the uniquely corresponding lower bent segment 21 is an upper magnetic side 14, the side of each lower bent segment 21 with respect to the uniquely corresponding upper bent segment 11 is a lower magnetic side 24, and the polarities of each upper magnetic side 14 and each lower magnetic side 24 are the same. It is therefore easy to see that, in practical applications, the rolling elements 3 may use magnetic beads with the same polarity as the upper magnetic side 14 and the lower magnetic side 24, so that the rolling elements 3 may be subjected to repulsive forces from the upper magnetic side 14 and the lower magnetic side 24, respectively, and thus the rolling elements 3 may be approximately suspended between the upper curved segment 11 and the lower curved segment 21, thereby further improving the rolling performance of the rolling elements 3. Of course, in practical applications, the polarity of the rolling elements 3 may also be opposite to the upper magnetic side 14 and the lower magnetic side 24, so that the rolling elements 3 may be magnetically attracted by the upper magnetic side 14 and the lower magnetic side 24, respectively, and thus the rolling elements 3 may be suspended between the upper curved segment 11 and the lower curved segment 21 as well.
In the present embodiment, as shown in fig. 4, since both the upper magnetic side 14 and the lower magnetic side 24 are spherical, the repulsive force applied to the rolling elements 3 by the upper magnetic side 14 and the lower magnetic side 24 can be distributed relatively uniformly at each position of the rolling elements 3, and the stability of the rolling elements 3 during rolling can be further improved.
In addition, as shown in fig. 4, each upper magnetic side 14 preferably further has a boss 5 for passing through the rolling element 3, and the boss 5 is rotatably engaged with the rolling element 3. The convex columns 5 can position the rolling bodies 3, so that the rolling performance of the rolling bodies 3 can be further improved. In addition, the convex column 5 used in the present embodiment is a magnetic column, and the polarity of the magnetic column is the same as that of the rolling element 3, so that the rolling element 3 does not come into contact with the convex column 5 when rolling, and the rolling performance of the rolling element 3 can be further improved. Of course, in practical applications, the stud 5 may also be disposed on the lower magnetic side 24.
A second embodiment of the present invention relates to a bearing, as shown in fig. 5, the bearing including: the bearing comprises an inner bearing body 7 and an outer bearing body 8 which are coaxially arranged along a preset axis, wherein the inner bearing body 7 is arranged in the outer bearing body 8, and the outer side face 71 of the inner bearing body 7 and the inner side face 81 of the outer bearing body 8 are mutually separated to form an annular area 9.
As shown in fig. 5, the bearing according to the present embodiment further includes: the rolling elements 3 are rotatably disposed in the respective housing spaces 6 of the bearing cage as described in the first embodiment. Meanwhile, the retainer is arranged in the annular area 9 and is coaxially arranged with the inner bearing body 7 and the outer bearing body 8, and each rolling body 3 is respectively abutted with the outer side face 71 of the inner bearing body 7 and the inner side face 81 of the outer bearing body 8.
Meanwhile, the outer side surface 71 of the inner bearing body 7 is formed with an annular outer groove 72 into which each rolling element 3 is partially fitted, in the direction of the predetermined axis. The inner side 81 of the outer bearing body 8 also forms, in the direction of the predetermined axis, an annular inner channel 82 in which the rolling elements 3 are partially embedded.
Through the above, it is not difficult to find that, since the positioning grooves 13 are respectively formed on one side of each lower horizontal section 22 uniquely corresponding to the lower frame body 2 of each upper horizontal section 12 of the upper frame body 1 of the retainer, and meanwhile, the positioning blocks 23 are respectively arranged on one side of each lower horizontal section 22 uniquely corresponding to the upper frame body 1 of each lower horizontal section 22 of the lower frame body 2, when the upper frame body 1 and the lower frame body 2 are assembled, through the cooperation of each positioning block 23 and each positioning groove 13, the upper frame body 1 and the lower frame body 2 can be quickly positioned during the assembly, and each rolling element is ensured to have better rolling performance in the accommodating space 6 surrounded by each upper bending section 11 and each lower bending section 21 uniquely corresponding to each rolling element, so that abnormal mechanical abrasion of the bearing can be avoided during the use, and the service life of the bearing is prolonged.
It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
