Abstract
This utility model relates to a kind of double row angular contact bearing, including inner ring and outer ring, described inner ring and outer ring arranged concentric and leave space between the two, two row straight flute roads circumferentially it have been evenly arranged on the outer surface of described inner ring and the inner surface of outer ring, between be arranged with two row steel balls, the angle between line and radial direction between described steel ball and inner ring and the contact point of outer ring is contact angle a, and this contact angle a is 25 °.Contact angle of the present utility model is 25 °, it is main radial and axial joint load and moment load that this angular contact ball bearing can bear bigger radial load, limit the axial displacement of both sides of axle, bear two-way equal axial load simultaneously, increase the product life-span operationally, extend bearing and use the time.
Description
Technical field
This utility model relates to field of bearings, particularly relates to a kind of double row angular contact bearing.
Background technology
Bearing is a kind of part conventional in industrial equipment, and its model is numerous, and existing frequently-used bearing is all
Standard component, as long as carrying out selecting according to practical situation, but if sometimes needs bigger axle
To bearing capacity and radial load, it is necessary to existing bearing is carried out special design and improves.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of double row angular contact bearing, its contact angle
Being 25 °, it is main radial and axial joint load that this angular contact ball bearing can bear bigger radial load
And moment load, limit the axial displacement of both sides of axle, bear two-way equal axial load simultaneously,
Increase the product life-span operationally, extend bearing and use the time.
This utility model solves its technical problem and be the technical scheme is that a kind of double row angular contact of offer
Bearing, including inner ring and outer ring, described inner ring and outer ring arranged concentric and leave space between the two,
Two row straight flute roads circumferentially it have been evenly arranged on the outer surface of described inner ring and the inner surface of outer ring, it
Between the line that is arranged with between two row steel balls, described steel ball and inner ring and the contact point of outer ring with radially
Angle between direction is contact angle a, and this contact angle a is 25 °.
Supplementing as to the one of technical scheme described in the utility model, the thickness of described inner ring is more than
The thickness of outer ring.
Supplement as to the one of technical scheme described in the utility model, between described inner ring and outer ring
The nylon cages being connected with steel ball is installed.
Further, centre distance b between the center of circle of two row steel balls is 3.5mm-3.8mm.
Beneficial effect
This utility model relates to a kind of double row angular contact bearing, and its contact angle is 25 °, this angular contact ball axle
Holding and bearing bigger radial load is main radial and axial joint load and moment load, limits axle
Both sides axially displacement, bears two-way equal axial load simultaneously, increases the product longevity operationally
Life, extends bearing and uses the time, and compared with single-row angular contact ball bearing, double-row angular contact bal bearing has
Preferably rigidity, can bear tilting moment, and bearing is Nonseparation, is particularly well-suited to there is high rigid requirements
And having the application scenario using two set specifications and models bearings of the same race, it is considered to bearing limit speed is higher, therefore one
As use nylon cages carry out supporting so that bearing temperature rise fall little.
Accompanying drawing explanation
Fig. 1 is of the present utility model partly to cut open topology view.
Diagram: 1, outer ring；2, inner ring；3, steel ball；4, nylon cages.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further.Only should be understood that these embodiments
For this utility model being described rather than limiting scope of the present utility model.In addition, it is to be understood that reading
After the content that this utility model is lectured, this utility model can be made various changing by those skilled in the art
Moving or amendment, these equivalent form of values fall within the application appended claims limited range equally.
As it is shown in figure 1, embodiment of the present utility model relates to a kind of double row angular contact bearing, including interior
Circle 2 and outer ring 1, described inner ring 2 and outer ring 1 arranged concentric and leave space between the two, described
Two row straight flute roads circumferentially it have been evenly arranged on the outer surface of inner ring 2 and the inner surface of outer ring 1, between
Be arranged with two row steel balls 3, the line between described steel ball 3 and the contact point of inner ring 2 and outer ring 1 with
Angle between radial direction is contact angle a, and this contact angle a is 25 °.
Supplementing as to the one of technical scheme described in the utility model, the thickness of described inner ring 2 is big
Thickness in outer ring 1.
Supplement as to the one of technical scheme described in the utility model, described inner ring 2 and outer ring 1
Between the nylon cages 4 being connected with steel ball 3 is installed.
Further, centre distance b between the center of circle of two row steel balls 3 is 3.5mm-3.8mm.
Its contact angle of bearing described in the utility model is 25 °, and this angular contact ball bearing can bear bigger
Radial load be main radial and axial joint load and moment load, the both sides limiting axle is axial
Displacement, bears two-way equal axial load simultaneously, increases the product life-span operationally, extends bearing
The use time, compared with single-row angular contact ball bearing, double-row angular contact bal bearing has more preferable rigidity,
Can bear tilting moment, bearing is Nonseparation, is particularly well-suited to have high rigid requirements and has use two sets
The application scenario of specifications and models bearing of the same race, it is considered to bearing limit speed is higher, therefore typically use nylon to protect
Hold frame and carry out supporting so that bearing temperature rise fall is little.
