Description
Technical field
The present invention relates to field of bearings, more particularly to a kind of double-row angular contact bal bearing in the same direction.
Background technology
Traditional taper roll bearing can bear the load of radial direction, the load of axial direction and radial load and the group of axial load
Load is closed, and larger load can be born and there is higher bearing rigidity.It is therefore nearest applied in all trades and professions, being particularly
Several years more to be applied in the industry centered on automobile.
In recent years in response to national policy and the demand of the people, automobile industry is actively drawn close in terms of environmental protection, is adjusted
Whole vehicle structure coordinates social to resources conservation and the requirement of low environmental load now with accessory scheme.
And in the moment of friction of the bearing arrangement in the steering spindle for reducing automobile engine or speed changer, the rolling of traditional circular cone
Sub- bearing can not meet to require, therefore needs to provide a kind of lower bearing of moment of friction and replaced.
For this applicant carried out beneficial exploration and trial, result of the above problems is have found, will be detailed below being situated between
The scheme to continue is caused by under this background.
The content of the invention
The technical problems to be solved by the invention are too high for existing bearing frictional torque and provided a kind of double in the same direction
Row angular contact ball bearing reduces bearing in automobile engine or the moment of friction of the bearing arrangement of the steering spindle of speed changer.
Technical problem solved by the invention can be realized using following technical scheme：
Double-row angular contact bal bearing in the same direction, including：
One outer race, two parallel interior raceways are provided with the inner peripheral surface of the outer race；
One bearing inner ring, the bearing inner ring are located in the outer race, set on the outer peripheral face of the bearing inner ring
It is equipped with two parallel outer raceways, two parallel outer raceways on the outer peripheral face of the bearing inner ring and the outer race
The corresponding combination of two interior raceways on inner peripheral surface forms the first circuit and the second circuit；
The first row spherical roller being arranged in first circuit and the secondary series ball being arranged in second circuit
Shape roller, wherein the first row spherical roller contacts with the inside and outside rolling path rolling in first circuit, the secondary series ball
Shape roller contacts with the inside and outside rolling path rolling in second circuit, it is characterised in that the ball in the first row spherical roller
Shape roller diameter and the spherical roller diameter in the secondary series spherical roller are unequal.
In a preferred embodiment of the invention, the centre of sphere of the spherical roller in the first row spherical roller with it is described
The centre of sphere of spherical roller in secondary series spherical roller is not on same side face.
In a preferred embodiment of the invention, the spherical roller in the first row spherical roller is kept by first
Frame is kept, and the spherical roller in the secondary series spherical roller is kept by the second retainer.
As a result of technical scheme as above, the beneficial effects of the present invention are：
Biserial ball-type roller in the same direction instead of taper roller, between the roller and raceway of double-row angular contact bal bearing in the same direction
Contact area diminishes, the moment of friction of double-row angular contact bal bearing and the frictional force of taper roll bearing in the same direction in the case of normal temperature
Square is as shown in Figure 1.The reduction of moment of friction, the application in automobile support shaft to be significantly increased in transmission efficiency, reduce
Friction loss, fuel mileage about 2.5% can be increased, reduce the discharge of carbon dioxide.
