Description
Technical field
The present invention relates 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.
Invention 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 present invention adopts the following technical scheme that：
A kind of double-row angular contact bal bearing, including outer ring, 2 inner rings, 2 retainers, be located in 2 retainers
2 row steel balls and spacer, 2 raceways are equipped in the endoporus of the outer ring, and the retainer is universal retainer；The inner ring
Outer circumference surface 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, and 2 described interior
Circle is oppositely arranged, and described between being set on 2 inner rings；Between the retainer and the endoporus of the outer ring
Gap is 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 technical effects of the invention are that：
A kind of double-row angular contact bal bearing disclosed by the invention, simple and compact for structure, manufacturing cost is low, using in seperated two
Circle and spacer structure, improving bearing, two row steel balls bear the situation of axial load at work, improve the rigidity of system, extend
The service life of bearing.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
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 embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, 3, the present invention includes 2,2 retainers 4 of inner ring of outer ring 1,2, is located at 2 retainers 4
In 2 row steel balls 3 and spacer 5,2 raceways are equipped in the endoporus of outer ring 1, retainer 4 is universal retainer.Outside inner ring 2
Periphery 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, the low gear of inner ring 2
The outer circumference surface of avris 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 are in inside, and spacer 5 is arranged between 2 inner rings 2, the both ends of the spacer 5 inner end phase with 2 inner rings 2 respectively
It supports.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 it is outer
Gap B between the endoporus of circle 1 is 0.3 millimeter.
In the present invention, inner ring 2 is designed to two and centre is equipped with spacer 5, and high gear is arranged in the outside of the raceway of inner ring 2
Low gear side 22 is arranged in side 21, inside, and bearing preload lotus can accordingly be preloaded by matching the width of spacer 5, bearing
Two row steel balls can bear axial load simultaneously at work, improve the rigidity and service life of system.In addition, inner ring 2 is set
It is in pyramidal to count into the high rib in side, side low gear side, and the outer circumference surface of the low gear avris of inner ring 2, and bearing is in production group
More convenient when dress, production efficiency can be improved 30%.Retainer 4 uses general structure, increases the intensity of retainer while can
Increase by 2 ~ 3 steel balls with crown type frame than in the prior art, bearing life can improve 1 ~ 2 times more.Meanwhile retainer 4 with it is outer
Gap B between the endoporus of circle 1 is controlled between smaller 0.2 ~ 0.4 millimeter, and retainer 4 is guided by outer ring 1, the limit of bearing
Rotating speed can improve 1 ~ 2 times, be suitable for running at high speed.
