Abstract
The invention relates to a self-aligning roller bearing which comprises an outer ring, an inner ring and a roller; the bearing adopts a structure with a wide outer ring and a narrow inner ring; the wide outer ring adopts a spherical raceway; the narrow inner ring adopts a double spherical raceway; the roller is uniformly separated by bearing retainers and runs in the spherical raceway of the wide outer ring. When the bearing of the invention is compared with the prior art, the width of the outer ring is larger than the width of the inner ring; the self-aligning angle of the bearing is larger than that of common self-aligning roller bearings, which enables the bearing to better meet the requirements and performance of equipment hosts; the length of the bearing spherical roller is larger than that of common bearing rollers, and thus the bearing capability of the bearing is stronger; the spherical roller of the bearing is separated uniformly by two polyamide-reinforced nylon retainers; the bearing can be used in gearboxes of roller drums of cement mixers which require stable and reliable running, a large self-aligning angle, and strong bearing capability.
Description
Technical field
The present invention relates to a kind of bearing, especially relate to a kind of selfaligning roller bearing.
Background technique
At present, in concrete mixer speed reducer industry with bearing, use large aligning angle, high loading, rugged environment in.Conventionally adopt common selfaligning roller bearing, this bearing aligning angle is little, and the life-span is lower, simultaneously high to the precision prescribed of axle, needs every year to change once, has increased undoubtedly the cost of enterprise, and changes cumbersomely, has reduced working efficiency.
Summary of the invention
Object of the present invention is exactly to provide in order to overcome the defect that above-mentioned prior art exists the selfaligning roller bearing that a kind of performance is better, Applicable scope is wider.
Object of the present invention 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, described wide outer ring adopts spherical raceway, described narrow inner ring adopts two spherical raceways, described roller turns round in the even separation of bearing cage the spherical raceway in wide outer ring, pilot bearing smooth operation.
Described retainer is that polyamide strengthens 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 present invention has the following advantages:
1, outer ring width widen, the aligning angle of bearing increases, and has reduced the machining accuracy error due to axle simultaneously, and the error to bearing in installation process has played good compensating action, 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 bearing and better meets requirement and the performance of device Host;
4, adopt polyamide to strengthen 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
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, outer ring 1 adopts spherical raceway, inner ring 2 adopts biserial spherical raceway, and roller 3 is spherical aligning lengthening roller, and retainer 4 is polyamide enhancing nylon retainer.Roller 3 is evenly separated and turns round in the spherical raceway of outer ring 1 through retainer 4, thus pilot bearing smooth operation.The aligning angle of this bearing be 3 ° 42 ', 14 ° 46 of bearing nominal contact angle '.
This bearing is due to the width widen of outer ring 1, the aligning angle of bearing increases, reduced the machining accuracy error due to axle simultaneously, error to bearing in installation process has played good compensating action, and in addition, inner ring 2 adopts biserial spherical raceway, and aligning roller 3 is strengthened to lengthening, can bear maximum radial load, the aligning angle of bearing is larger than conventional selfaligning roller bearing, is beneficial to bearing and better meets requirement and the performance of device Host.The polyamide adopting strengthens 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. a 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, described wide outer ring adopts spherical raceway, described narrow inner ring adopts two spherical raceways, and described roller turns round in the even separation of bearing cage 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 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 '.
