Abstract
The utility model relates to a low-noise roller bearing which comprises an inner ring, an outer ring, a tapered roller and a retainer; the bearing is of a split-type structure; an inner component consists of the inner ring, the retainer and the tapered roller; and the inner component and the outer ring are installed separately. Compared with the prior art, the low-noise roller bearing has the advantages of nice noise reduction effect, high reliability and wide application.
Description
Technical field
The utility model relates to a kind of bearing, especially relates to a kind of low noise tapered roller bearing.
Background technique
Bearing is with the motor long-term operation, operating ambient temperature can reach more than 150 ℃, turn scooter 5000 to turn/more than the min, domestic bearing installing space is less, is unfavorable for turning round under high temperature, the operating mode at a high speed, and is present in addition, more and more tight to the requirement of noise in advanced country, the use of home brands elevator abroad, therefore, also become a vitals in the staircase motor at speed reducer industry middle (center) bearing, especially to noise requirement, life requirements, load bearing requirements.
The model utility content
The purpose of this utility model is exactly to provide in order to overcome the defective that above-mentioned prior art exists that a kind of excellent noise reduction effect, reliability are high, the low noise tapered roller bearing of applied range.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of low noise tapered roller bearing comprises inner ring, outer ring, tapered roller, retainer, it is characterized in that, described bearing is split-type structural, and described inner ring, retainer and tapered roller form internal component, and install respectively this internal component and outer ring.
The component processing tolerance of size of this bearing adopts highi degree of accuracy grade P5 level.
Described inner ring is provided with the arc structure rib, and this rib adopts hard Vehicle Processing technique.
The surperficial plain line of described tapered roller is the correction of the flank shape of arc generatrix convexity.
Described retainer is the retainer that hardens, to gain in strength.
The surface roughness of this bearing adopts highi degree of accuracy rank 6X level.
The nominal contact angle of this bearing is 38 ° 48 ' 39 of large cone angle ".
Compared with prior art, the utlity model has following advantage:
1, satisfied external advanced country, home brands elevator use in to the requirement of noise, can effectively reduce its noise by internal component and outer ring are installed respectively;
2, the reliability of bearing is high, the component processing tolerance of size of this bearing adopts the highi degree of accuracy grade, adopt hard Vehicle Processing technique on the inner ring, retainer is the retainer that hardens, the surface roughness of bearing adopts the highi degree of accuracy rank, nominal contact angle is large cone angle, above all reliability and Securities in order to improve bearing, and further reduced its noise.
3, applied range, the low noise tapered roller bearing replaces common tapered roller bearing, is used for 4 grades of motors of staircase, has made on the speed reducer industry a new step, reach domestic and international advanced level, also can be used for the industries such as automobile, milling train, mine, metallurgy, plastics machinery
