Abstract
The utility model relates to a self-aligning roller bearing which comprises an outer ring, an inner ring and rollers; the bearing adopts a wide outer ring and a narrow inner ring; the wide outer ring adopts a spherical raceway, and the narrow inner ring adopts double spherical raceways; and the rollers are uniformly separated through the bearing retainer and rotate in the spherical raceway of the wide outer ring. Compared with the prior art, the bearing outer ring is wider than the inner ring; a self-aligning angle of the bearing is larger than that of the conventional self-aligning roller bearing, so that the bearing is able to favorably satisfy requirements and performance of the equipment host; spherical rollers of the bearing are longer than the conventional bearing roller, so that the bearing has stronger loading ability; the spherical rollers of the bearing are uniformly separated by two polyamide reinforced nylon retainers; and the bearing is applied to a gearbox of a roller of a cement mixer, with stable and reliable rotation, great self-aligning angle and strong loading ability.
Description
Technical field
The utility model relates to a kind of bearing, especially relates to a kind of selfaligning roller bearing.
Background technique
At present, use bearing in the concrete mixer speed reducer industry, use large aligning angle, high loading, rugged environment in.Usually adopt common selfaligning roller bearing, this bearing aligning angle is little, and the life-span is lower, and the precision prescribed to axle is high simultaneously, and annual the needs changed once, increased undoubtedly the cost of enterprise, and changes cumbersomely, has reduced working efficiency.
The model utility content
The purpose of this utility model is exactly to provide the selfaligning roller bearing that a kind of performance is better, Applicable scope is wider for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of selfaligning roller bearing, comprise outer ring, inner ring and roller, this bearing adopts the structure of wide outer ring and narrow inner ring, spherical raceway is adopted in described wide outer ring, described narrow inner ring adopts two spherical raceways, described roller turns round the pilot bearing smooth operation in the even separation of bearing cage and the spherical raceway in wide outer ring.
Described retainer is that polyamide strengthens the nylon retainer.
Described roller is that spherical aligning lengthens roller.
The aligning angle of this bearing be 3 ° 42 ', 14 ° 46 of bearing nominal contact angle '.
Larger than conventional selfaligning roller bearing.
Compared with prior art, the utlity model has following advantage:
1, outer ring width widen, the aligning angle of bearing increases, and has reduced simultaneously because the machining accuracy error of axle has played good compensating action to the error of bearing in installation process, reaches domestic and international advanced level;
2, adopt selfaligning roller bearing, aligning roller strengthens and lengthens, and can bear maximum radial load, very suitable concrete mixer industry heavy duty requirement;
3. the aligning angle of bearing is larger than conventional selfaligning roller bearing, is beneficial to requirement and performance that bearing better meets device Host;
4, adopt polyamide to strengthen the nylon retainer, separation bearing aligning roller that can be good reduces friction, reduces noise, and the good running in bearing of guiding aligning roller is durable in use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of selfaligning roller bearing, its structure as shown in Figure 1, comprise outer ring 1, inner ring 2, roller 3 and retainer 4, this bearing adopts the structure of wide outer ring and narrow inner ring, spherical raceway is adopted in outer ring 1, inner ring 2 adopts the biserial spherical raceway, and roller 3 lengthens roller for spherical aligning, and retainer 4 strengthens the nylon retainer for polyamide.Roller 3 is evenly separated and is turned round in the spherical raceway of outer ring 1 through retainer 4, thus the pilot bearing smooth operation.The aligning angle of this bearing be 3 ° 42 ', 14 ° 46 of bearing nominal contact angle '.
This bearing is because the width widen of outer ring 1, the aligning angle of bearing increases, reduced simultaneously because the machining accuracy error of axle, the error of bearing in installation process played good compensating action, and in addition, inner ring 2 adopts the biserial spherical raceway, and aligning roller 3 is strengthened lengthening, can bear maximum radial load, the aligning angle of bearing is larger than conventional selfaligning roller bearing, is beneficial to requirement and performance that bearing better meets device Host.The polyamide that adopts strengthens the nylon retainer, and separation bearing aligning roller that can be good reduces friction, reduces noise, the good running in bearing of guiding aligning roller.
Claims (4)
1. selfaligning roller bearing, comprise outer ring, inner ring and roller, it is characterized in that, this bearing adopts the structure of wide outer ring and narrow inner ring, spherical raceway is adopted in described wide outer ring, described narrow inner ring adopts two spherical raceways, and described roller turns round in the even separation of bearing cage and the spherical raceway in wide outer ring.
2. a kind of selfaligning roller bearing according to claim 1 is characterized in that, described retainer is that polyamide strengthens the nylon retainer.
3. a kind of selfaligning roller bearing according to claim 1 is characterized in that, described roller is that spherical aligning lengthens roller.
4. a kind of selfaligning roller bearing according to claim 1 is characterized in that, the aligning angle of this bearing be 3 ° 42 ', 14 ° 46 of bearing nominal contact angle '.
