Abstract
The utility model discloses a self-aligning roller bearing, which comprises an outer ring (1) and an inner ring (2); wherein, the outer ring (1) is formed by two semicircular half outer rings; the outer surface of the outer ring (1) is fixed by a plastic loop (5); two stress grooves (3) are arranged on the outer surface of the outer ring (1); flanges (4) are arranged on the roller way of the outer ring (1); the inner ring (2) does not need nicks for rollers any more; cages (6) for isolating the rollers are dispensed with; and the jointed rollers are fully arranged in the circumference of the raceway. Since the self-aligning roller bearing with the particular structure does not have the cages, a larger space is provided for more rollers; while the diameter and length of the roller are optimized, the rollers are fully loaded along the circumference of the raceway; the outer ring is divided into two parts along the radial symmetric surfaces to form the two separable outer rings; and more rollers can be loaded in the self-aligning roller bearing, so that the higher rated load can be obtained.
Description
Technical field
The utility model relates to a kind of selfaligning roller bearing, especially relates to a kind of selfaligning roller bearing that can completely adorn roller.
Background technique
Selfaligning roller bearing is commonly used in heavy duty and the workplace of aligning performance requirement is arranged, 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 selfaligning roller bearing under the restriction in certain boundary dimension space, can only pack into the roller of suitable quantity and the restriction of roller size, shown in Figure of description 1, because the bearing rated load is main relevant with the roller size with the quantity of roller, and bearing interior space is held the frame part that accounts for, the roller quantity that can adorn be restricted, the restriction of outer ring during in addition owing to the bearing assembling, also can limit to some extent more roller quantity of packing into, finally limit the further raising of bearing load carrying capacity.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of selfaligning roller bearing at problems of the prior art, its objective is to greatest extent the roller quantity that increases in the outer ring of packing into and the size of roller, to increase the bearing capacity of selfaligning roller bearing, satisfy heavy duty and impact the harsh usage requirement of occasion.
The technical solution of the utility model is that this a kind of selfaligning roller bearing comprises outer ring and inner ring, and described outer ring radially symmetry is divided at least two parts, and the outer surface of outer ring is provided with the stress groove, and the raceway of outer ring is provided with rib.
Described outer ring is made up of two semicircular semi outer rings, and the outer surface of outer ring is fixed by ring set.
Described stress groove has two.
Described ring set is the plastics ring set.
A kind of selfaligning roller bearing with above-mentioned special construction has the following advantages:
1, this kind selfaligning roller bearing has been cancelled retainer, more rollers provide bigger space in order to pack into, when optimizing roller diameter and length, roller is completely packed into along the raceway circumferential row, outer ring radially symmetry plane is divided into two, become separable two outer rings, the roller quantity more of can packing into, thus can obtain maximum rated load.
2, outer ring raceway leaves little rib restriction roller and drops out and leave the leeway of moving for aligning, and bearing had not only guaranteed that bearing roller can not drop out but also guarantee that this selfaligning roller bearing remains a cover solid bearing performance in carrying, installation, using process.
3, this kind selfaligning roller bearing has improved the bearing rated load more than 30%, thereby makes cost reduce about 20% owing to reduced retainer simultaneously.
4, 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 the structural representation of existing selfaligning roller bearing.
Fig. 2 is a structural representation of the present utility model.
In Fig. 1～2,1: the outer ring; 2: inner ring; 3: the stress groove; 4: rib; 5: ring set; 6: retainer.
Embodiment
Figure 1 shows that the structural representation of existing selfaligning roller bearing.By as can be known shown in Figure 1, the inner space of existing selfaligning roller bearing is held frame 6 part that accounts for, the roller quantity that can adorn be restricted, be subjected to the restriction of outer ring 1 during in addition owing to the bearing assembling, also can limit to some extent more roller quantity of packing into, finally limit the further raising of bearing load carrying capacity.
Fig. 2 is the structural representation of the utility model selfaligning roller bearing.By as can be known shown in Figure 2, this kind selfaligning roller bearing comprises outer ring 1, inner ring 2, and outer ring 1 radially symmetry is divided into two semicircles, and fixing by the plastics ring set 5 that is positioned on 1 outer surface of outer ring, the outer surface of outer ring 1 is provided with two stress grooves 3, and the raceway of outer ring 1 is provided with rib 4.
Concrete installation process is: the breach that no longer needs to adorn roller on the inner ring 2, cancelled the retainer 6 that is used to isolate roller, the full raceway circumference of the row of roller and roller connecting part, the middle part design of outer ring 1 has stress groove 3, after outer ring 1 normal process is finished, pressing off outer ring 1 along stress groove 3 is two semi outer rings, in bearing roller is all packed into latter two double semi outer rings of raceway along bearing shaft to packing into, two semi outer rings are closed up and together, with plastics ring set 5 two semi outer rings are fixedly become one then, leaving rib 4 on the raceway of outer ring 1 drops out from outer ring 1 with the restriction roller, can leave the leeway of moving for aligning again, bearing is in carrying, install, remain a cover solid bearing performance in the using process.
Claims (4)
1. selfaligning roller bearing, comprise outer ring (1) and inner ring (2), it is characterized in that: described outer ring (1) radially symmetry is divided at least two parts, and the outer surface of outer ring (1) is provided with stress groove (3), and the raceway of outer ring (1) is provided with rib (4).
2. a kind of selfaligning roller bearing according to claim 1 is characterized in that: described outer ring (1) is made up of two semicircular semi outer rings, and the outer surface of outer ring (1) is fixing by ring set (5).
