Description
Technical field
The utility model relates to technical field of bearings, particularly relates to a kind of combination bearing.
Background technique
Conventionally in mechanical device, angular contact ball bearing is all to exist with matching form, and adopt Spielpassung between outer ring and bearing support, and be difficult to control because the variation of the existence of inner hole of bearing seat tolerance, bearing top circle tolerance and work heating rear bearing cylindrical, inner hole of bearing seat size all can allow the use level of Spielpassung become, thereby affect the precision of whole mechanical device.
As shown in Figure 1, be existing general bearing configuration, configuration is made up of angular contact ball bearing and one group of spacer ring of a pair of back-to-back (DB), between bearing outer ring and bearing support, adopts Spielpassung.But because bearing support and bearing outer ring itself all exist size deviation, and when real work, temperature rise meeting changes a lot size, therefore the gap between bearing outer ring and bearing support is difficult to control, excesssive gap there will be " circle of acting as a travelling agent " phenomenon, the too small stuck phenomenon that there will be in gap.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of combination bearing, can overcome the unstability of mechanical device precision, realize the simplification, integrated of multiple classification bearings simultaneously, especially can realize the integrated of a pair of back to back angle contact ball bearing and linear bearing.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of combination bearing is provided, match with bearing support, comprise: outer ring, be arranged at the first retainer assembly between outer raceway and the described bearing support of described outer ring, inner ring, and be arranged at the second retainer assembly between the raceway of described inner ring and the interior raceway of described outer ring, wherein, the interior raceway of described outer ring comprises the first interior raceway and the second interior raceway, described inner ring comprises the first inner ring and the second inner ring that structure is identical, described the first inner ring and the back-to-back setting of described the second inner ring, between the first interior raceway of the raceway of described the first inner ring and described outer ring, between the second interior raceway of the raceway of described the second inner ring and described outer ring, be provided with one group of second retainer assembly.
In preferred embodiment of the utility model, described the first retainer assembly is made up of the first rolling element and the first retainer, and itself and described outer ring and described bearing support form a linear bearing.
In preferred embodiment of the utility model, described the second retainer assembly is made up of the second rolling element and the second retainer, and described in two groups, the second retainer assembly and described outer ring, described the first inner ring and described the second inner ring form back-to-back angular contact ball bearing.
In preferred embodiment of the utility model, the outer raceway both sides of described outer ring all offer locking groove, in described locking groove, are installed with stopper ring, and described the first retainer assembly is spacing by described stopper ring.
The beneficial effects of the utility model are: the utility model is by merging into an outer ring by two outer rings of pair of horns contact ball bearing, inner ring using this outer ring as linear bearing simultaneously, gap between combination bearing and bearing support is under control, can overcome the unstability of mechanical device precision, realize the simplification, integrated of multiple classification bearings simultaneously, especially can realize the integrated of a pair of back to back angle contact ball bearing and linear bearing.
