Abstract
The utility model discloses an angular contact ball bearing with double outer rings, which is provided with outer rings (1) and an inner ring (2), two groups of retainers (6) are arranged between outer rings (1) and the inner ring (2) and are fixed with two groups of spherical rollers (4). The angular contact ball bearing with double outer rings is characterized in that outer rings (1) are made of two divided outer rings whose structures are symmetrical, wherein outer internal diameters of outer rings (1) have hold depth, the inner external diameters are guidance surface of retainers (6), two divided outer rings are formed with an oil groove and an oil hole, the inner ring (2) is an incorporated structure, the inner external diameter of the inner ring (2) has hold depth, and two groups of retainers (6) are respectively matched with two groups of spherical rollers (4). The structure of the utility model is provided with double outer rings, double retainers and singe inner ring, which is easy for fixing. Spherical rollers (4) are not damaged when fixing, thereby guaranteeing operating life of the bearing. The utility model is provided with the oil groove and the oil hole, thereby being convenient for adding grease and good in greasing effect, reducing noise, bearing wear and overheat due to being.
Description
Technical field:
The utility model relates to a kind of bearing, especially a kind of two foreign angular contact ball bearings.
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: a foreign country, 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, foreign country need add thermal expansion, exerted pressure again, steel ball could be pressed in the interior foreign country.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 utility model provides a kind of convenient for assembly at the above-mentioned deficiency of prior art, can guarantee the bearing two foreign angular contact ball bearing in working life.
Technical solution of the present utility model is: a kind of two foreign angular contact ball bearings, be provided with foreign country and inner ring, between foreign country and inner ring, be provided with retainer, two groups of spherical rollers are installed in the retainer, described foreign country is made of two symmetrical branch foreign countries of structure, the outer internal diameter of foreign country has hold depth, and interior external diameter is the guiding surface of retainer, constitutes oil groove and oilhole between two fens foreign countries; Inner ring is structure as a whole, and interior domestic external diameter has hold depth; Retainer is two groups, is complementary with two groups of spherical rollers respectively.
Structure of the present utility model is two foreign countries, 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 in foreign country, 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 utility model.
Fig. 2 divides the structural representation of foreign country for the utility model.
Fig. 3 is the structural representation of the utility model inner ring.
Embodiment:
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 1 ~ 3, a kind of two foreign angular contact ball bearing, be provided with foreign country 1 and inner ring 2, be provided with retainer 6 in foreign country 1 and 2 of inner rings, two groups of spherical rollers 4 are installed in the retainer 6, described foreign 1 is made of two symmetrical branch foreign countries of structure, the outer internal diameter of foreign country 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 foreign countries; 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.
