The technical scheme is adopted, and the method has the advantages that: the annular framework is stably placed on the bearing outer ring through the matching of the annular clamping block and the annular clamping groove, so that the anti-overturning rings extending towards the rolling cavity of the annular framework can be stably placed in the rolling cavity and are arranged in a clearance fit manner with the adjacent annular blocking rings, when the bearing outer ring has an overturning phenomenon, the bearing outer ring can move along with the annular framework and drive the annular framework to move, the anti-overturning rings on the annular framework are abutted against the adjacent annular blocking rings at the moment, the annular framework cannot move continuously, the bearing outer ring cannot be greatly overturned to separate from the bearing inner ring when the bearing bears high-rated load, the bearing cannot fail, the anti-overturning capacity of the bearing outer ring can be improved through the arrangement of the annular clamping block and the anti-overturning rings, and the overturning angle of the bearing outer ring is reduced when the bearing is subjected to the high-rated load, in the technology, the anti-tilting ring inclines towards the rolling body direction, and the annular baffle ring and the corresponding anti-tilting ring have the same tilting direction, so that the tilting angle of the bearing outer ring is further limited when the bearing outer ring is subjected to high load, and the phenomenon of large-amplitude tilting of the bearing outer ring is further ensured.

The utility model discloses further set up: all set up on outer lane internal perisporium and the inner circle periphery wall and supply the rolling raceway of rolling element, two the equal hoop in raceway both sides is provided with the anticreep ring, set up the arcwall face that supplies the rolling element subsides to establish on the lateral wall of anticreep ring one side of raceway.

The technical scheme is adopted, and the method has the advantages that: the equal annular of raceway both sides is provided with anticreep ring and still is provided with the arcwall face on the anticreep ring, and when bearing outer lane received high load and this load impact the rolling element and lead to the rolling element to rock on the raceway, the local periphery wall of rolling element can contact with the arcwall face for the rolling element can not break away from the raceway when receiving load impact, leads to the bearing inefficacy.

The utility model discloses further set up: two it has the subsides ring, two all to extend towards the rolling element direction on the anti shroud ring internal perisporium paste the ring and all be close to outer lane internal perisporium setting, two it all sets up with outer lane internal perisporium clearance fit to paste the ring.

The technical scheme is adopted, and the method is beneficial to that: the sticking ring is in clearance fit with the inner peripheral wall of the outer ring, so that the anti-tilting ring cannot be driven to move by load impact force transmitted by the inner ring of the bearing when the inner ring of the bearing bears radial load, the annular framework cannot easily fall off from the outer ring of the bearing, and the anti-tilting ring can be normally matched with the annular retaining ring.

The utility model discloses further set up: two it has a plurality of spacing rings all to protruding on the wall to paste the ring periphery, it all is provided with the spacing groove, every to correspond every spacing ring position on the outer lane internal perisporium the spacing ring sets up and every spacing ring all sets up with the spacing groove grafting cooperation that corresponds with every spacing groove one-to-one.

The technical scheme is adopted, and the method has the advantages that: the cooperation of spacing ring and spacing groove further ensures that the annular skeleton can not break away from the bearing inner race when the bearing inner race bears high-load, and then ensures that anti-tilting shroud ring can normally cooperate with annular fender ring.

The utility model discloses further set up: two equal cavity has been seted up and has been stored up fat chamber on the sticking ring, two it has solid-state grease, two all to fill in the storage fat chamber all set up the oil outlet with adjacent storage fat chamber intercommunication on the sticking ring lateral wall, two the oil outlet all sets up towards the rolling element direction.

The technical scheme is adopted, and the method has the advantages that: when the bearing runs at a high speed, the temperature in the bearing can gradually rise, so that the local solid grease in the grease storage cavity can be gradually converted into liquid grease and flows into the rolling cavity from the oil outlet, the lubrication of the rolling body is realized, and the dry rotation phenomenon of the rolling body in the running process is further avoided.

The utility model discloses further set up: the annular clamping block is matched with the annular clamping groove through a stamping process.

The technical scheme is adopted, and the method has the advantages that: the annular clamping block is matched with the annular clamping groove through a stamping process, so that the annular framework is prevented from being separated from the bearing outer ring easily.
