Abstract

The utility model relates to a biserial self-aligning roller bearing which comprises an outer ring and an inner ring, wherein, two retainers are arranged between the outer ring and the inner ring. The utility model is characterized in that each pocket hole of the retainers is respectively provided with rollers of which the end surface is provided with concave apertures. The retainers corresponding to the concave apertures on the end surface of the rollers are provided with crank arms to form S-shaped retainers. The crank arms on the retainers are respectively embedded in the corresponding concave apertures on the end surface of the rollers. The utility model which can disengage from the inner ring and the outer ring to be independently installed, which means that a copper hammer or rod is used to slightly beat to cause the rollers to be put in the pocket holes of the retainers and not easy to fall off has the main advantages of simple structure, convenient installation, low material cost and light weight. Furthermore, the utility model can increase the rated moving load and the rated static load of the bearing, wherein, the rated moving load can be increased by 10%, and the service life of the bearing is enhanced by 30%-50%.

Description

Double-row self-aligning roller bearing
(1) technical field
The utility model relates to a kind of bearing, especially relates to a kind of double-row self-aligning roller bearing.
(2) background technique
Existing selfaligning roller bearing is generally established an annular boss at the internal diameter middle part of retainer, form the Spielpassung face with bearing inner race centre rib position, the rotation of centre rib guiding retainer, when bearing rotates, the annular boss and the bearing inner race centre rib at the internal diameter middle part of retainer have relative movement, easily cause the wearing and tearing of retainer internal diameter, if will improve the bearing capacity of bearing, the length of roller will extend, and this just causes retainer boss width narrow, insufficient strength, become the weak link of bearing, the early stage damage of bearing will be caused if damage in this position, influences the working life of bearing, therefore, the annular boss structure at retainer internal diameter middle part has limited the raising of bearing load carrying capacity, has influenced application area.In addition, existing selfaligning roller bearing, adopt wear resistance good copper product is made more, and the cost of retainer is raised.
(3) summary of the invention
The purpose of this utility model provides a kind of easy for installation, cost is low, bearing capacity is strong double-row self-aligning roller bearing.
The technological scheme that adopts is:
Double-row self-aligning roller bearing comprises outer ring, inner ring, is equiped with two retainers between outer ring and inner ring, is equiped with the roller of end face band depression in each pocket hole of retainer respectively, on the retainer with roller end face on the depression corresponding part connecting lever is arranged, constitute The type retainer.Connecting lever on the retainer embeds respectively in the depression on the with it corresponding roller end face.
Major advantage of the present utility model is:
1, simple in structure, easy for installation and can break away from bearing enclose and independently install, promptly one strike gently with beautiful spotflower herb or rod, roller can be packed in the retainer pocket hole, and difficult drop-off.
2, save material, former retainer is a centrifugal casting brass, price height, heavy, the utility model adopts 35 or 45 cold rolled sheets, and blank can be welded, and the cost of material is low, in light weight, in addition, no matter bearing inner race Vehicle Processing or to grind processing more convenient easily.
3, compare with brass solid cage and steel plate pressing cage, it can hold, and diameter is bigger, length is longer, more aligning roller, thereby can improve the dynamic load rating and the rated static load of bearing, finally reach and improve the bearing effect in working life, by theoretical calculation, generally can improve dynamic load rating 10%, bearing improves 31-50% working life.
(4) description of drawings
Fig. 1 is the double-row self-aligning roller bearing sectional view of the utility model pressing cage.
(5) embodiment
See also Fig. 2, double-row self-aligning roller bearing of the present utility model comprises outer ring 1, inner ring 2, two groups of rollers 3 and two retainers 4.Wherein the structure of outer ring 1, inner ring 2 is known technology, and its characteristics are to be equiped with respectively in each pocket hole of retainer 4 roller 3 of end face band depression 5, on the retainer 4 with roller 3 end faces on depression 5 corresponding parts connecting lever 6 is arranged, constitute The type pressing cage.Connecting lever 6 on the retainer 4 embeds respectively in the depression 5 on it corresponding roller 3 end faces.。
During assembling, retainer can break away from bearing enclose and independent assembling, be that aligning roller one strikes in the retainer pocket hole of can packing into gently from outside to inside with beautiful spotflower herb or rod, but can not all fill the pocket hole, each sheet retainer is reserved 1-2 pocket hole in the diametric(al) position, two retainer roller assemblies of all not filling the pocket hole are packed in this bearing outer ring together with inner ring, change an angle then, in the pocket hole of reserving, aligning roller is tapped down aligning roller from outside to inside again, till filling with above-mentioned same method.

Claims (1)

1, double-row self-aligning roller bearing, comprise outer ring (1), inner ring (2), between outer ring (1) and inner ring (2), be equiped with two retainers (4), it is characterized in that being equiped with respectively in each pocket hole of described retainer (4) roller (3) of end face band depression (5), there is connecting lever (6) on the retainer (4) and depression (5) corresponding part on roller (3) end face, constitutes Type retainer, the connecting lever (6) on the retainer (4) embed respectively in the depression (5) on it corresponding roller (3) end face.
