Description
Technical field
The utility model is related to a kind of high speed compound ball bearing, the double raceway circles of more particularly to a kind of high speed compound ball bearing
Body.
Background technology
Bearing is widely used as a kind of parts for supporting mechanical rotary body, and the common general rotating speed of bearing is arrived thousands of
10000 revs/min, indivedual bearings improve speed by adjusting the methods of oil clearance, precision and lubricant, but with each
The continuous development of a scientific domain, the demand of high-speed bearing is more and more, high speed compound profile shaft hold can meet it is more high-revolving
It is required that.
Invention content
The purpose of this utility model is a kind of double raceway circle bodies of high speed compound ball bearing of design so that high speed compound ball bearing
It is achieved.
To achieve these goals the technical scheme adopted by the utility model is that：A kind of double raceway circles of high speed compound ball bearing
Body, double raceway circle bodies include two arc-shaped rails, and the arc-shaped rail one is arranged in double raceway circle bodies
Inner surface, an outer surface for being arranged in double raceway circle bodies；The inner surface arc-shaped rail center and described
On one wire, the inner surface arc-shaped rail places a circle bearing ball, described double at outer surface arc orbit center
Outer ring of the raceway circle body for first bearing, the outer surface arc-shaped rail place a circle bearing ball, double raceways
Inner ring of the circle body as second bearing, first bearing and second bearing form radial compound.
Selectively, the inner surface arc-shaped rail center and the outer surface arc orbit center be not at one
On line, the inner surface arc-shaped rail places a circle bearing ball, and double raceway circle bodies are the outer ring of first bearing,
The outer surface arc-shaped rail places a circle bearing ball, inner ring of the double raceway circle bodies as second bearing, institute
It states 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, is must tying of can realizing of high speed compound ball bearing
Structure.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings.
Fig. 1 is the double raceway circle body sectional views of a kind of high speed compound ball bearing that the utility model embodiment provides；

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 Fig. 1, a kind of double raceway circle bodies of high speed compound ball bearing, double raceway circle bodies include two it is arc-shaped
Track, the arc-shaped rail one are arranged in the inner surface of double raceway circle bodies, and one is arranged in double raceway circles
The outer surface of body；11 center of inner surface arc-shaped rail and 12 center of outer surface arc orbit are in a line
On, the inner surface arc-shaped rail 11 places a circle bearing ball, and double raceway circle bodies are the outer ring of first bearing,
The one circle bearing ball of the placement of outer surface arc-shaped rail 12, inner ring of the double raceway circle bodies as second bearing,
First bearing and second bearing form radial compound.
As shown in Fig. 2, selectively, the inner surface arc-shaped rail center 21 and the outer surface circular arc rail
Not on one wire, the inner surface arc-shaped rail 21 places a circle bearing ball, double raceway circle bodies at road 22 center
For the outer ring of first bearing, the outer surface arc-shaped rail 22 places a circle bearing ball, and double raceway circle bodies are made
For the inner ring of second bearing, first bearing and second bearing form axial composite-rotor.
