Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Consult Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, it is single roller bearing that the present invention can use first preferred embodiment of the roller bearing in twice life-span, and comprise an inner ring body 2, outer ring body 3, two groups of roller means 4,5, an and retainer 6.
This inner ring body 2 comprises reverse an internal diameter anchor ring 21 and an external diameter anchor ring 22, and two intervals are arranged with the groove 23 in this external diameter anchor ring 22.In this first preferred embodiment, this external diameter anchor ring 22 has a channel guide section 221 that is arranged with and supplies described groove 23 to arrange, and two perimembranous 222 that are formed at respectively these channel guide section both sides Shang Xia 221, by described groove 23, this channel guide section 221 is divided into a central segment 223 that is positioned at 23 of described grooves, and a lateral margin section 224 that is positioned at 223 liang of opposition sides of this central segment.
These outer ring body 3 spacer sleeves are located at this inner ring body 2, and comprise an inner ring surface that is adjacent to this external diameter anchor ring 22 31, an outer ring surface 32 reverse with this inner ring surface 31, and two intervals are arranged with in the groove 33 of this inner ring surface 31 and corresponding described groove 23, described groove 33 makes this inner ring surface 31 form a central segment 313 that is positioned at 33 of described grooves, and a lateral margin section 314 that is positioned at 313 liang of opposition sides of this central segment.
Described roller means 4,5 can be replaced and be installed on 31 of the channel guide section 221 of this inner ring body 2 and the inner ring surfaces of this outer ring body 3.Each group roller means 4,5 comprise several can be at the channel guide section 221 of this external diameter anchor ring 22 and the roller 41,51 of 31 rollings of this inner ring surface.The outer circumferential face 411,511 of each roller 41,51 is divided into a contact area 412,512 contacting with this inner ring surface 31 with these external diameter anchor ring 22 channel guide section 221, and diameter be less than this contact area 412,512 and with these external diameter anchor ring 22 channel guide section 221 and the discontiguous relief areas 413,513 of this inner ring surface 31, and described groove 23 and described groove 33 are aimed at the boundary of this relief area 413,513 in this contact area 412,512.
This retainer 6 is installed on this inner ring body 2 and 3 of this outer ring bodies and places for described roller 41,51.In this first preferred embodiment, this retainer 6 comprises that one around the dicyclo body 61 of these inner ring body 2 perimembranous 222, and several intervals stand on the rib 62 of this dicyclo body 61, every two adjacent ribs 62 and this dicyclo body 61 are around the space 63 that defines one of them roller 41 placement of a confession, and this dicyclo body 61 is formed in one with this rib 62.
Consult Fig. 6, the contact area 412 of the roller means 4 of first group is around its outer circumferential face 411 center and contact these inner ring body 2 central segment 223 and this outer ring body 3 central segment 313, and the relief area 413 of the roller means 4 of first group is formed at the both sides up and down of this contact area 412.Consult Fig. 7, the relief area 513 of the roller means 5 of second group is around its outer circumferential face 511 center, and its contact area 512 is formed at the both sides up and down of this relief area 513 and contacts these inner ring body 2 lateral margin sections 224 and this outer ring body 3 lateral margin sections 314, profile is by chance contrary with this first group of roller means 4, that is, the roller 41 of first group of roller means 4 is middle protrusion, and the roller 51 of second group of roller means 5 is intermediate recess.
During installation, consult Fig. 5, Fig. 6, first this retainer 6 be set in to this inner ring body 2 and be placed in this channel guide section 221, again the roller of first group of roller means 4 41 is installed on one by one in the space 63 of this retainer 6, and make its contact area 412 support the central segment 223 of these external diameter anchor ring 22 channel guide section 221, now, described groove 23 is aimed in 413 boundaries, 412Yu Gai relief area, contact area of each roller 41.Finally this outer ring body 3 is sheathed on to this inner ring body 2 and this retainer 6, and the central segment 313 of this inner ring surface 31 is supported in the contact area 412 that makes each roller 41 simultaneously, now this outer ring body 3 grooves 33 are also aimed in the boundary of 412Yu Gai relief area, this contact area 413, so complete installation.
When this roller bearing in use, these inner ring body 2 central segment 223, these outer ring body 3 central segment 313 wear away mutually for line contacts also with roller 41 contact areas 412 of first group of roller means 4, the burr chip producing enters in described groove 23 and described groove 33, and can not cause the stuck problem of described roller 41.After a period of time to be used, this roller bearing, because abrasion are cannot regular event time, can replace with second group of roller means 5 and continue to use.While using for the first time, because only having central segment 223, this inner ring body 2 is worn away, and this outer ring body 3 only has central segment 313 to be worn away, as shown in Figure 7, the contact area 512 of second group of roller means 5 is not yet this lateral margin section 224 and this lateral margin section 314 of abrasion of contact, therefore, replace with after second group of roller means 5, this bearing just can continue to use.Importantly, user also can change erection sequence, first selects second group of roller means 5 is installed, then replaces with first group of roller means 4, all can be able to use the object in twice life-span.
