Abstract
The invention discloses an angular contact ball bearing with double outer rings, which is provided with an outer ring (1) and an inner ring (2); a retainer (6) is arranged between the outer ring (1) and the inner ring (2); and the inside of the retainer (6) is provided with two groups of spherical rollers (4). The angular contact ball bearing is characterized in that: the outer ring (1) consists of two split outer rings with symmetrical structures, the outer internal diameter of the outer ring (1) has locking amount, the inner external diameter of the outer ring (1) is a guide surface of the retainer, and an oil groove and an oil hole are formed between the two split outer rings; the inner ring (2) has an integral structure, and the inner external diameter (7) of the inner ring (2) has locking amount; and the retainer (6) is two groups, and the two groups are respectively matched with the two groups of spherical rollers (4). The structure of the bearing is provided with the double outer rings, double retainers and a single inner ring, so the bearing is easy to mount and assemble. In the assembly process, the spherical rollers are not damaged, so that the service life of the bearing is ensured. Moreover, the outer ring is provided with the oil groove and the oil hole so as to facilitate adding lubricating grease, and the lubricating grease has good lubricating effect, reduces noise and reduces bearing wear and overheating.
Description
Technical field:
The present invention relates to a kind of bearing, especially a kind of angular contact ball bearing with double outer rings.
Background technique:
Double-row angular contact bal bearing, majority belong to pair bearing that rolling mill uses, and mainly contain following structural type at present: an outer ring, two inner rings, two rows are installed in two steel balls on the retainer respectively, form a cover bearing.Its shortcoming is that the interior external diameter of inner ring has hold depth.When bearing assembled, because of interior external diameter has hold depth, the outer ring need add thermal expansion, exerts pressure again, steel ball could be pressed in the Internal and external cycle.Since when assembling steel ball produce powerful friction, make steel ball be subjected to serious damage, reduced bearing working life.
Summary of the invention:
The present invention is directed to the above-mentioned deficiency of prior art, provide a kind of convenient for assembly, can guarantee the bearing angular contact ball bearing with double outer rings in working life.
Technical solution of the present invention is: a kind of angular contact ball bearing with double outer rings, 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, described outer ring is made of two symmetrical branch outer rings of structure, the outer internal diameter of outer ring has hold depth, and interior external diameter is the guiding surface of retainer, constitutes oil groove and oilhole between two fens outer rings; Inner ring is structure as a whole, and external diameter has hold depth in the inner ring; Retainer is two groups, is complementary with two groups of spherical rollers respectively.
Structure of the present invention is two outer rings, two retainers, and single inner ring is easy to install assembling.To the spherical roller not damaged, guaranteed the life-span that bearing uses during assembling.And on the outer ring, be provided with oil groove and oilhole, the convenient lubricating grease that adds, lubrication effect is good, reduces noise, reduces bearing wear and overheated.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 divides the structural representation of outer ring for 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 angular contact ball bearing with double outer rings, be provided with outer ring 1 and inner ring 2, in the outer ring 1 and 2 of inner rings be provided with retainer 6, two groups of spherical rollers 4 are installed in the retainer 6, described outer ring 1 is made of two symmetrical branch outer rings of structure, the outer internal diameter of outer ring 1 has hold depth, interior external diameter is the guiding surface of retainer, and the rotation of guiding retainer constitutes oil groove and oilhole between two fens outer rings; Inner ring 2 is structure as a whole, and external diameter 7 has hold depth in the inner ring 2; Retainer 6 is two groups, is complementary with two groups of spherical rollers 4 respectively.
Claims (1)
1. angular contact ball bearing with double outer rings, be provided with outer ring (1) and inner ring (2), between outer ring (1) and inner ring (2), be provided with retainer (6), two groups of spherical rollers (4) are installed in the retainer (6), it is characterized in that: described outer ring (1) is made of two symmetrical branch outer rings of structure, the outer internal diameter of outer ring (1) has hold depth, and interior external diameter is the guiding surface of retainer, constitutes oil groove and oilhole between two fens outer rings; Inner ring (2) is structure as a whole, and the interior external diameter of inner ring (2) (7) has hold depth; Retainer (6) is two groups, is complementary with two groups of spherical rollers (4) respectively.
