Description
Technical field
The utility model is related to a kind of high speed compound roller bearing, the double raceways of more particularly to a kind of high speed compound roller bearing
Circle body.
Background technology
Bearing is the important foundation parts of all kinds of mechanized equipments, for the connection and support of fixing piece and revolving part, by
In the limit value of design feature, the rotating ratio of plain bearing is relatively low, usual 10,000 revs/min or so, but with advances in technology,
The development of production, demand of the product to high-speed bearing is more and more, and various types of high-speed bearing innovative ability constantly meets industrial biography
Dynamic needs.
Invention content
The purpose of this utility model is a kind of double raceway circle bodies of high speed compound roller bearing of design so that high speed compound roller
Bearing is achieved.
To achieve these goals the technical scheme adopted by the utility model is that：A kind of double raceways of high speed compound roller bearing
Circle body, double raceway circle bodies include two grooves, and the groove one is arranged in the inner surface of double raceway circle bodies, and one
A outer surface for being arranged in double raceway circle bodies, the inner side surface recess bottom surface and the outer surface groove floor are put down
Row is in longitudinal center line, and the inner side surface recess bottom center and the outer surface groove floor center are in straight line
On；The inner side surface recess places a circle bearing roller, and double raceway circle bodies are described outer i.e. as first bearing outer ring
Side surface groove places a circle bearing roller, and double raceway circle bodies are i.e. as second bearing inner race, first bearing
Radial compound is formd with second bearing.
Selectively, the inner side surface recess bottom surface and the outer surface groove floor are not parallel to axial centre
Line.
Selectively, the inner side surface recess bottom center and the outer surface groove floor center be not straight at one
On line, the inner side surface recess places a circle bearing roller, and double raceway circle bodies are described outer i.e. as clutch shaft bearing outer ring
Side surface groove places a circle bearing roller, double raceway circle bodies i.e. as second bearing inner ring, first bearing and
Second bearing forms axial composite-rotor.
The utility model has taken into account the effect of bearing inner race and outer ring, provides high speed compound roller bearing a kind of novel circle body
Component.

Specific embodiment
It is new to this practicality below in conjunction with attached drawing to make the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
As shown in Figure 1, a kind of double raceway circle bodies of high speed compound roller bearing, double raceway circle bodies include two grooves,
The groove one is arranged in the inner surface of double raceway circle bodies, an outside table for being arranged in double raceway circle bodies
Face, 11 bottom surface of inner side surface recess and 12 bottom surface of outer surface groove are parallel to longitudinal center line, the inside table
11 bottom center of face groove and 12 bottom center of outer surface groove are point-blank；The inner side surface recess 11 is put
A circle bearing roller is put, for double raceway circle bodies i.e. as first bearing outer ring, the outer surface groove 12 places a circle
Bearing roller, double raceway circle bodies are i.e. as second bearing inner race, first bearing and second bearing shape
Into radial compound.
As shown in Fig. 2, selectively, 21 bottom surface of inner side surface recess and 22 bottom surface of outer surface groove are uneven
Row is in longitudinal center line.
As shown in figure 3, selectively, 31 bottom center of inner side surface recess and 32 bottom surface of outer surface groove
Not point-blank, the inner side surface recess 31 places a circle bearing roller at center, and double raceway circle bodies are i.e. as the
One bearing outer ring, the outer surface groove 32 place a circle bearing roller, and double raceway circle bodies are i.e. as in second bearing
Circle, first bearing and second bearing form axial composite-rotor.
