Abstract
The invention discloses an oversize self-aligning roller bearing, which is provided with an outer ring (1) and an inner ring (2). A retainer is arranged between the outer ring (1) and the inner ring (2), and two groups of spherical rollers (4) are arranged in the retainer. The oversize self-aligning roller bearing is characterized in that: the rotation center of each spherical roller (4) is provided with a through hole; and the retainer consists of a pin shaft (9), and an inner plate annular retainer (6) and an outer plate annular retainer (16) at two ends of the pin shaft (9), wherein the pin shaft (9) runs through the through hole at the rotation center of the spherical roller (4), and the inner plate annular retainer and the outer plate annular retainer are arranged at two end faces of the spherical roller (4). The retainer is not integrated, but assembled, so the requirement of assembly precision between the retainer and the spherical rollers is reduced, and the retainer is easy to process and reduces the manufacturing cost. Moreover, the bearing can increase the number of the rollers as much as possible, and improves the rated load.
Description
Technical field:
The present invention relates to the oversize self-aligning roller bearing of a kind of bearing, particularly a kind of new structure.
Background technique:
Bearing has been widely used in various mechanical fields as standard piece commonly used, but there are the following problems for wide serial extra large size bearing existing structure:
1, crossbeam will have certain width to satisfy the requirement of strength of retainer between the pectination retainer two pocket holes of existing structure, has so just limited increasing of roller quantity, has limited the raising of bearing rated load.
2, will there be certain containing amount at the pectination retainer pocket hole of existing structure place, otherwise very easily falls roller, and this just requires the external diameter of retainer can not be too little, but can not be too big, otherwise bearing assembling difficulty, this has increased the difficulty of wide serial design bearing.
3, the pectination retainer of existing structure, because there is machining error in the pocket bore dia, also there is machining error in roller, though both errors are all very little in control range, but the little and roller maximum case of pocket Kongzui the time may occur and eat up a part of gap in assembling, adding the pocket hole, to add the man-hour retainer yielding, causes center, pocket hole deviation directly to occur, and these phenomenons add and easily cause bearing assembling back revolution dumb together.
4, because the pectination retainer size of extra large size bearing is bigger, the cost of work card measurer is also than higher.
Summary of the invention:
The present invention is directed to the above-mentioned deficiency of prior art, provide a kind of easy to assembly, processing is simple, the oversize self-aligning roller bearing that bearing capacity is strong.
Technical solution of the present invention is: a kind of oversize self-aligning roller bearing, be provided with outer ring and inner ring, between outer ring and inner ring, be provided with retainer, two groups of spherical rollers are installed in the retainer, the gyration center of each spherical roller has a through hole, described retainer is by bearing pin, reach the interior tabular annular retainer at bearing pin two ends, outer tabular annular retainer formation, wherein bearing pin is through the through hole at spherical roller gyration center place, and inside and outside tabular annular retaining is placed on the spherical roller both ends of the surface.
Described bearing pin preferably is riveted joint with outer tabular annular retainer, with interior tabular annular retainer for being threaded convenient installation.
Retainer of the present invention is not an integrative-structure, but assembles, and this has just reduced the requirement of assembly precision between retainer and spherical roller, and this retainer be easy to processing, reduced manufacture cost.And this bearing can increase roller quantity as much as possible, has improved its rated load.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of outer ring of the present invention.
Fig. 3 is the structural representation of inner ring of the present invention.
Embodiment:
Further specify the specific embodiment of the present invention below in conjunction with accompanying drawing.
Shown in Fig. 1 ~ 3, a kind of oversize self-aligning roller bearing, be provided with outer ring 1 and inner ring 2, outer ring 1 has internal spherical surface raceway, inner ring 2 is not with centre rib and little rib, in the outer ring 1 and 2 of inner rings be provided with retainer, two groups of spherical rollers 4 are installed in the retainer, the gyration center of each spherical roller 4 has a through hole, described retainer is by bearing pin 9, and the interior tabular annular retainer 6 at bearing pin 9 two ends, outer tabular annular retainer 16 constitutes, and wherein bearing pin 9 is through the through hole at spherical roller 4 gyration center places, in, outer tabular annular retainer places spherical roller 4 both ends of the surface.Every cover bearing has four tabular annular retainers, and wherein two in the bearing both ends of the surface, in addition two in bearing, and inside and outside supporting in twos use.Described bearing pin 9 is riveted joint with outer tabular annular retainer 16, and bearing pin 9 and interior tabular annular retainer 6 are for being threaded.
Claims (2)
1. oversize self-aligning roller bearing, be provided with outer ring (1) and inner ring (2), between outer ring (1) and inner ring (2), be provided with retainer, two groups of spherical rollers (4) are installed in the retainer, it is characterized in that: the gyration center of each spherical roller (4) has a through hole, described retainer is by bearing pin (9), and the interior tabular annular retainer (6) at bearing pin (9) two ends, outer tabular annular retainer (16) constitutes, wherein bearing pin (9) is through the through hole at spherical roller (4) gyration center place, in, outer tabular annular retainer places spherical roller (4) both ends of the surface.
