Description
Technical field
Bearing parts technical field is the utility model is related to, is related specifically to a kind of strengthened heat dissipation type angular contact ball bearing.
Background technology
Bearing is a kind of important spare part in contemporary plant equipment.Its major function is the mechanical rotary body of support, is reduced
Coefficient of friction in its motion process, and ensure its rotating accuracy.
By the difference of motor element frictional property, bearing can be divided into rolling bearing and the major class of sliding bearing two.Wherein roll
Bearing is normalized, seriation, but its radial dimension, vibration and noise are larger compared with sliding bearing, and price is also higher.
Rolling bearing is typically made up of outer ring, inner ring, rolling element and the part of retainer four, is strictly speaking by outer ring, inner ring, rolling
Body, retainer, sealing, six big part of lubricating oil composition.In simple terms, as long as possessing outer ring, inner ring, rolling element just may be defined as
Rolling bearing.By the shape of rolling element, rolling bearing is divided into ball bearing and the major class of roller bearing two.
At present, the angular contact ball bearing that in the market is produced can bear radial load and axial load simultaneously.Can be higher
Rotating speed under work.Contact angle is bigger, and axial carrying capacity is higher.High accuracy and high-speed bearing generally take 15 degree of contact angles.
Under responsive to axial force, contact angle can increase.Therefore the friction and heating of angular contact ball bearing are more violent, caused temperature compares
Height, how effectively to be radiated on the premise of bearing overall structure is not changed, turn into a urgent problem to be solved.
The content of the invention
Technical problem to be solved in the utility model is the defects of overcoming prior art, there is provided it is a kind of simple in construction,
On the premise of not changing existing bearing overall structure, increase heat dispersion, reduce caloric value, improve the reinforcement of bearing service life
Heat radiating type angular contact ball bearing.
To achieve these goals, the utility model uses following technical scheme：
Strengthened heat dissipation type angular contact ball bearing, including a bearing inner race, a bearing outer ring and be assemblied in both it
Between angular contact ball, it is characterised in that：Described bearing inner race is internally provided with the interior radiating groove of annular, the inside of bearing outer ring
The outer radiating groove of annular is provided with, the center of circle of interior radiating groove and outer radiating groove is concentric with bearing；Described interior radiating groove and outer
The cross sectional shape of radiating groove is the hook-type that one section of straight line adds one section of circular arc, wherein the center of circle of one section of circular arc and angular contact ball
With one heart, and circular arc angle be less than 45 degree；Described interior radiating groove and outer radiating groove are symmetrical using the center of circle of angular contact ball
Point, structure in a center of symmetry.
In such scheme, the straightway of described interior radiating groove gets through the surface of bearing inner race, the circular arc of interior radiating groove
The end of shape section is fillet；The straightway of described outer radiating groove gets through the surface of bearing outer ring, the circular arc section of outer radiating groove
End be also fillet.
In such scheme, the height of described interior radiating groove is less than 1/3rd of bearing inner race thickness, outer radiating groove
Height be less than bearing outer ring thickness 1/3rd.
The utility model is by adopting the above-described technical solution, have the advantages that：
It is simple in construction, on the premise of existing bearing overall structure is not changed, by increasing capacitance it is possible to increase heat dispersion, reduce heating
Amount, improve bearing service life.

The cross sectional shape of heat channel 4 and outer radiating groove 5 is the hook-type that one section of straight line adds one section of circular arc, wherein the center of circle of one section of circular arc
It is concentric with angular contact ball 3, and the angle of circular arc is 44 degree；Described interior radiating groove 4 and outer radiating groove 5 are with angular contact ball 3
The center of circle be symmetric points, structure in a center of symmetry.
In the present embodiment, the straightway of described interior radiating groove 4 gets through the surface of bearing inner race 1, the circle of interior radiating groove 4
The end of segmental arc is fillet；The straightway of described outer radiating groove 5 gets through the surface of bearing outer ring 2, the circular arc of outer radiating groove 5
The end of shape section is also fillet.
In the present embodiment, the height of described interior radiating groove 4 is less than 1/3rd of the thickness of bearing inner race 1, outer radiating
The height of groove 5 is less than 1/3rd of the thickness of bearing outer ring 2.
Particular embodiments described above, technical problem, technical scheme and the beneficial effect solved to the utility model are entered
Further description is gone, should be understood that and the foregoing is only specific embodiment of the utility model, and do not have to
