Abstract
The utility model relates to a double row angular contact ball bearing consisting of an outer ring, two inner rings, two retainers and two rows of steal balls, which is characterized in that the out inside diameter of outer ring having lock amount is the guide plane of the retainer; the corresponding part of the inside and outside diameter of the two inner rings and the steal balls are separately provided with chiseled marks. As the outer ring and inner rings of the utility model have no the lock amount, the inner rings can be conveniently discomposed for cleaning, particularly when in mounting the outer ring is not needed to be heat, the outer ring do not need to expand that the steal balls are not scratched in mounting, then the service life of bearing is improved. The utility model being convenient to be injected with lubricating oil has good lubricating performance.
Description
(1) technical field
The utility model relates to a kind of bearing, specifically relates to two inner ring angular contact ball bearings that a kind of inner ring does not have hold depth.
(2) background technique
Double-row angular contact bal bearing, majority belong to pair bearing that rolling mill uses, and mainly contain following three kinds of structural types at present:
One, outer ring, two inner rings, two rows are installed in two steel balls on the retainer respectively, form a cover bearing (see figure 1).Its shortcoming is that the outer internal diameter of outer ring has hold depth (slope).When bearing assembles because of outside internal diameter hold depth is arranged, the outer ring need add thermal expansion, exerts pressure again, is pressed in the Internal and external cycle, because steel ball produces powerful friction, makes steel ball be subjected to serious damage in when assembling, has reduced bearing working life.
Two, outer ring, outer internal diameter has hold depth (slope), two inner rings, interior external diameter becomes guide surface, the guiding retainer, two row's steel balls, two retainers are formed a cover bearing.Because outer internal diameter has hold depth, the same with first kind of double-row angular contact bal bearing during assembling, the outer ring need add thermal expansion when bearing assembles, and exerts pressure again, is pressed in the Internal and external cycle, and steel ball is scratched, reduction bearing working life.(see figure 2).
Three, outer ring, two inner rings, two row's steel balls, two retainers are assembled into a cover bearing.The outer internal diameter of the outer ring of this double-row angular contact bal bearing does not have hold depth, becomes guide surface, but the interior external diameter of two inner rings has hold depth.Therefore, when assembling is pressed into, can make steel ball that scuffing is arranged equally, reduce bearing working life.
(3) summary of the invention
The technical problem to be solved in the present invention, steel ball can not be scratched two inner ring angular contact ball bearings of long service life when providing a kind of assembling.
The technological scheme that adopts is:
Two inner ring angular contact ball bearings, be assembled into by an outer ring, two inner rings, two row's steel balls and two retainers, be characterized in: the outer internal diameter of outer ring does not have hold depth, and become the guide surface of retainer, two inner rings have the slope, but do not have hold depth, there is the cutter seal two retainer internal diameters and steel ball corresponding part, pin steel ball it is not come off.
The retainer end face is drilled with oilhole (the logical eye in each pocket hole).
The outer ring is provided with oil groove and oilhole.
The utility model does not all have hold depth because of outer ring, inner ring, and inner ring can be dismantled arbitrarily and clean, and is easy to loading and unloading, and does not heat the outer ring when particularly assembling, and does not need the outer ring to expand, and can not abrade steel ball during assembling, has improved the working life of bearing.It is convenient that the utility model injects lubricant oil, and greasy property is good.
(4) description of drawings
Fig. 1, Fig. 2, Fig. 3 are three kinds of known double-row angular contact bal bearings.Fig. 4 is a kind of example structure schematic representation of the present utility model.Fig. 5 is the outer ring structure schematic representation.Fig. 6 is the inner ring structural representation.Fig. 7 is retainer partial structurtes schematic representation.Fig. 8 is the A-A view of Fig. 7.Fig. 9 is a retainer internal diameter cutter seal schematic representation.
(5) embodiment
Two inner ring angular contact ball bearings are assembled into by outer ring 1, two inner rings 2, two retainers 3 and two row's steel balls 4.The outer internal diameter of outer ring 1 does not have hold depth, is the guiding surface of retainer, the rotation of guiding retainer; Outer ring 1 is provided with oil groove 5 and oilhole 6.The interior external diameter of two inner rings 2 has slope 7 respectively, does not have hold depth.On two retainer end faces, internal diameter and steel ball corresponding part that corresponding each pocket hole is provided with 8, two retainers of an oilhole are provided with cutter seal 9.Retainer 3 usefulness spheroidal graphite cast iron are made, and also available copper is made.
Claims (2)
1, two inner ring angular contact ball bearings are to be assemblied by outer ring (1), two inner rings (2), two retainers (3) and two row's steel balls (4), it is characterized in that:
The outer internal diameter of A, outer ring (1) does not have hold depth, is the retainer guide surface;
Slope (7) is arranged respectively on the interior external diameter of B, two inner rings (2);
The internal diameter of C, two retainers (3) and steel ball corresponding part offer cutter seal (9) respectively.
2, according to described pair of inner ring angular contact ball bearing of claim 1, it is characterized in that: outer ring (1) is provided with oil groove (5) and oilhole (6); On two retainer end faces, corresponding each pocket hole is provided with an oilhole (8).
