Abstract
The utility model relates to a self -aligning roller bearing, which comprises an inner ring and an outer ring, the inner circle is worn to establish in the outer lane, the 2 -3 that the length of inner circle is outer lane length doubly, a side end outer wall of inner circle is provided with the lock loop, seted up the locking screw hole on the lock loop, should lock the threaded hole screw in has and tightly decides the bolt, the perforation has been offered to interior circling, the tight lower extreme of deciding the bolt passes and places the inner circle after the perforation in. Will be tightly decide the bolt setting on the lock loop of setting up, the perforation that circles in the messenger is the unthreaded hole to the phenomenon that the inner circle splits has been avoided because of stress concentration.
Description
Technical field
The utility model relates to a kind of selfaligning roller bearing.
Background technique
Tradition selfaligning roller bearing, inner ring offering locking screw thread hole, then screws in Cock screw, being fixed by the axle be arranged in inner ring by tightening screw; Defect is in the past, because locking screw thread hole is directly opened on inner ring, there is the phenomenon that stress is concentrated, and when vibration appears in the axle in inner ring time, easily makes inner ring occur the phenomenon of brittle cracking.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of selfaligning roller bearing, solves the defect that inner ring is in the past easy to crack.
The utility model solves the technological scheme that its technical problem adopts: a kind of selfaligning roller bearing, comprise inner ring and outer ring, described inner ring is located in outer ring, the length of described inner ring is 2-3 times of outer ring length, one side end outer wall of described inner ring is provided with locking ring, described locking ring offers locking screw thread hole, and screwing in this locking screw thread hole has tight fixed bolt, described inner ring offers perforation, and the lower end of described tight fixed bolt is placed in inner ring through perforation.
Further, described perforation is unthreaded hole.
Further, described locking ring and interior ring outer wall form spiral and are connected.
Further, between described inner ring and outer ring, be provided with retainer, described retainer be provided with two row aligning roller groups, between described two row aligning roller groups, be provided with middle spacer ring.
The beneficial effects of the utility model are: be arranged on the locking ring set up by tight fixed bolt, make the perforation on inner ring be unthreaded hole, thus avoid inner ring stress and concentrate and the phenomenon of splitting.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the schematic diagram of the utility model selfaligning bearing;
Wherein, 1, inner ring, 2, outer ring, 3, locking ring, 4, tight fixed bolt, 5, perforation.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of selfaligning roller bearing, comprise inner ring 1 and outer ring 2, inner ring 1 is located in outer ring 2, and the length of inner ring 1 is 2-3 times of outer ring 2 length, and a side end outer wall of inner ring 1 is provided with locking ring 3, locking ring 3 offers locking screw thread hole, screw in this locking screw thread hole and have tight fixed bolt 4, inner ring 1 offers perforation 5, the lower end of tight fixed bolt 4 is placed in inner ring 1 through perforation 5.For avoiding inner ring 1 to produce the concentrated phenomenon of stress, perforation 5 is unthreaded hole.
Locking ring 3 forms spiral with inner ring 1 outer wall and is connected.Be provided with retainer between inner ring 1 and outer ring 2, retainer be provided with two row aligning roller groups, between two row aligning roller groups, be provided with middle spacer ring.
Time selfaligning bearing of the present utility model is arranged in rotating shaft, by being screwed down tight fixed bolt 4, realize the compression through rotating shaft, thus realize installing, owing to boring a hole 5 for unthreaded hole, therefore, there is not the phenomenon that stress is concentrated.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
