Description
Technical field
The utility model is related to a kind of bearings, more particularly, to a kind of double-row angular contact bal bearing.
Background technology
As shown in figure 4, outer ring 1 ' and inner ring 2 ' are structure as a whole, retainer 4 ' is existing double-row angular contact bal bearing
Crown type, retainer 4 ' are guided by steel ball 3 '.Steel ball number can make to fill out ball angle at 186 ° or so（Big steel ball dress is not entered）；Due to
Outer ring 1 ' and inner ring 2 ' are structure as a whole, and are unable to preload, bearing when bearing axial load a wherein row steel ball not by
Power, this load bearing row steel ball and raceway are easy to fail, and bearing is also just quickly invalidated, and service life is shorter.
Utility model content
The applicant is directed to above-mentioned problem, has carried out Improvement, provides a kind of double-row angular contact bal bearing, structure letter
Single compact, manufacturing cost is low, and improving bearing, two row steel balls bear the situation of axial load at work, improve the rigid of system
Property, extend the service life of bearing.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme：
A kind of double-row angular contact bal bearing, including outer ring, 2 inner rings, 2 retainers, it is located at 2 retainers
In 2 row steel balls and spacer, 2 raceways are equipped in the endoporus of the outer ring, the retainer is universal retainer；In described
The outer circumference surface of circle is equipped with raceway, and the side of the raceway of the inner ring is equipped with high rib, and the other side is equipped with low gear side, 2 institutes
It states inner ring to be oppositely arranged, and described between being set on 2 inner rings；The endoporus of the retainer and the outer ring it
Between gap between 0.2 ~ 0.4 millimeter.
Further：
Gap between the retainer and the endoporus of the outer ring is 0.3 millimeter.
The outer circumference surface of the low gear avris of the inner ring is in pyramidal.
The utility model has technical effect that：
A kind of double-row angular contact bal bearing disclosed by the utility model, simple and compact for structure, manufacturing cost is low, using fission
Two inner rings and spacer structure, improving bearing, two row steel balls bear the situation of axial load at work, improve system
Rigidity, extends the service life of bearing.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is enlarged drawing at the A of Fig. 1.
Fig. 3 is the structural schematic diagram of retainer.
Fig. 4 is the structural schematic diagram of double-row angular contact bal bearing in the prior art.
Specific implementation mode
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, 3, the utility model includes 2,2 retainers 4 of inner ring of outer ring 1,2, is located at 2 holdings
2 row steel balls 3 in frame 4 and spacer 5,2 raceways are equipped in the endoporus of outer ring 1, and retainer 4 is universal retainer.Inner ring 2
Outer circumference surface is equipped with raceway, and the side of the raceway of inner ring 2 is equipped with high rib 21, and the other side is equipped with low gear side 22, inner ring 2 it is low
The outer circumference surface of rib side is in pyramidal.2 inner rings 2 are oppositely arranged, i.e., the high rib 21 of 2 inner rings 2 is in outside, low gear
Side 22 is in inside, and spacer 5 is arranged between 2 inner rings 2, the both ends of spacer 5 inner end with 2 inner rings 2 respectively
It offsets.Gap B between retainer 4 and the endoporus of outer ring 1 is between 0.2 ~ 0.4 millimeter, in the present embodiment, retainer 4 with
Gap B between the endoporus of outer ring 1 is 0.3 millimeter.
In the present invention, inner ring 2 is designed to two and centre is equipped with spacer 5, and the outside of the raceway of inner ring 2 is arranged
Low gear side 22 is arranged in high rib 21, inside, and bearing preload lotus can accordingly be preloaded by matching the width of spacer 5,
Two row steel balls can bear axial load to bearing simultaneously at work, improve the rigidity and service life of system.In addition, inner ring
2 are designed to that the high rib in side, side low gear side, and the outer circumference surface of the low gear avris of inner ring 2 are in pyramidal, and bearing is producing
More convenient when assembling, production efficiency can be improved 30%.Retainer 4 uses general structure, increases the intensity of retainer simultaneously
Crown type frame that can be than in the prior art increases by 2 ~ 3 steel balls more, and bearing life can improve 1 ~ 2 times.Meanwhile retainer 4 with
Gap B between the endoporus of outer ring 1 is controlled between smaller 0.2 ~ 0.4 millimeter, and retainer 4 is guided by outer ring 1, the pole of bearing
Limit rotating speed can improve 1 ~ 2 times, be suitable for running at high speed.
