Abstract
The utility model discloses a single-row self-aligning roller bearing, which comprises an inner ring (1), an outer ring (2), rollers (3) and cages; wherein, both the inner ring (1) and the outer ring (2) are of a single-raceway arc-shaped structure; moreover, the inner ring (1) is provided with double-sided flanges (4); the rollers are arranged in a single row; each roller (3) which is of a hollow structure comprises three sections, which are arranged in order; the roller (3) is shaped like an integral arc; the cages comprise cage end covers (5) and cage pins (6); rivet holes are evenly distributed on the cage end covers (5); the cage pins (6) pass through the inner holes of the rollers (3); and both ends of the cage pins (6) are fixed by the cage end covers (5). The contact lengths between the inner and the outer rings and the rollers of the single-row self-aligning roller bearing with the particular structure are increased by 25 percent, the number of the rollers is increased by 20 percent, as a result, the bearing capability of the bearing is enhanced by 30 percent to 40 percent, while the material of the thick copper cages is saved, and the material cost is reduced by about 15 percent.
Description
Technical field
The utility model relates to a kind of single-row selfaligning roller bearing.
Background technique
The workplace that single-row selfaligning roller bearing is commonly used in heavy duty and has aligning performance to require, because bearing is the supporting running part of mechanical axis, when bearing is used in axle bending deflection and heavily loaded complicated occasion are arranged, need bearing inner race and outer ring that concentric scarcely and dislocation are arranged, if this occasion occurs movement interference exactly with conventional bearing and causes the bearing premature failure, selfaligning bearing can be avoided this movement interference, guarantees that bearing has good runnability in these special use occasions.
Conventional single-row selfaligning roller bearing structure is shown in Figure of description 1, by the outer ring, inner ring, roller, retainer and isolating ring are formed, the roller of the suitable quantity of under the restriction in certain boundary dimension space, can only packing into and the restriction of roller size, limited the further raising of bearing load carrying capacity, roller is double column structure, retainer is mainly the copper physical machine and processes, because the structural limitations bearing length is restricted, the copper cage roller quantity that takes up room is restricted, because roller length is directly proportional with the load rating of bearing with roller quantity, therefore the bearing capacity of bearing is restricted, in addition owing to used the copper solid cage, complex structure, stock utilization is low, with a large amount of copper materials, increased the manufacture cost of this class bearing.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of single-row selfaligning roller bearing at problems of the prior art, its objective is the contact length that improves bearing race and roller to greatest extent, increasing the bearing capacity of single-row selfaligning roller bearing, and reduced the utilization rate of material.
The technical solution of the utility model is that this a kind of single-row selfaligning roller bearing comprises inner ring, outer ring, roller and retainer, inner ring and outer ring all are single raceway structures, and inner ring is provided with two-sided rib, roller is single-row layout, and roller is a hollow structure, and each roller comprises at least two sections, and retainer comprises retainer end cap and retainer pin, the retainer pin passes the hole of roller inside, and two ends are fixed by the retainer end cap.
Described roller comprises three sections, and three sections are arranged in order, and the profile of roller is the integrated type circular shape, and rolling matches with raceway on inner ring and the outer ring.
The raceway that matches with roller on described inner ring and the outer ring all is arcuate shape.
Be evenly equipped with rivet hole on the described retainer end cap, the retainer pin is fixed on the rivet hole by rivet.
A kind of single-row selfaligning roller bearing with above-mentioned special construction has the following advantages:
1, single-row selfaligning roller bearing inner ring of this kind and outer ring raceway and roller contact length have increased by 25%, roller quantity has increased by 20%, make the bearing capacity of bearing increase 30%-40%, and material has been saved thick and heavy copper cage, Master Cost reduces about 15%.
2, roller along its length can fine solution as 3 stops since the bearing roller overall length increase, when bearing rotates along the roller length direction owing to there is different linear velocities, cause roller to occur easily rolling and add the phenomenon of slip, problem such as generate heat when causing bearing operation.
3,, bring great convenience, and reduced the processing charges of product to a great extent for processing, measurement because inner ring becomes single raceway by original two raceways.
4, the retainer pin is installed in the hole of roller inside, and is fixed on the rivet hole uniform on the retainer end cap, and roller can be evenly distributed on the revolution circumference.
5, this protective gear preparation process is simple, uses reliably, and effect is obvious, has the excellent popularization using value.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is for having the structural representation of single-row selfaligning roller bearing now.
