Description
Technical field
The present invention relates to a kind of high speed compound ball bearing, the double raceway circle bodies of more particularly to a kind of high speed compound ball bearing.
Background technology
Bearing is widely used as a kind of parts for supporting mechanical rotary body, and the conventional general rotating speed of bearing arrives thousands of
10000 revs/min, the methods of indivedual bearings are by adjusting oil clearance, precision and lubricant, improves speed, but with each
The continuous development of individual 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.
The content of the invention
The purpose of the present invention is a kind of double raceway circle bodies of high speed compound ball bearing of design so that high speed compound ball bearing is able to
Realize.
The present invention adopts the technical scheme that to achieve these goals：A kind of double raceway circle bodies of high speed compound ball bearing,
Double raceway circle bodies include two arc-shaped rails, and the arc-shaped rail one is arranged in the inner side of double raceway circle bodies
Surface, an outer surface for being arranged in double raceway circle bodies；The inner surface arc-shaped rail center and the outside
On one wire, the inner surface arc-shaped rail places a circle bearing ball, double raceways at surface arc orbit center
Circle body is first bearing outer ring, and the outer surface arc-shaped rail places a circle bearing ball, and double raceway circle bodies are made
For second bearing inner race, the clutch shaft bearing and the 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 clutch shaft bearing outer ring, described
Outer surface arc-shaped rail places a circle bearing ball, and double raceway circle bodies are as second bearing inner ring, the first axle
Hold and form axial composite-rotor with the second bearing.
The present invention has taken into account the effect of bearing inner race and outer ring, is the necessary structure that high speed compound ball bearing can be realized.
Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, make required in being described below to embodiment
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for
For those of ordinary skill in the art, on the premise of not paying creative work, other can also be obtained according to these accompanying drawings
Accompanying drawing.

Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention
Formula 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 circular arcs
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；The center of inner surface arc-shaped rail 11 and the center of outer surface arc orbit 12 are in a line
On, the inner surface arc-shaped rail 11 places a circle bearing ball, and double raceway circle bodies are first bearing outer ring, institute
State outer surface arc-shaped rail 12 and place a circle bearing ball, double raceway circle bodies are described as second bearing inner race
Clutch shaft bearing and the second bearing are formd to 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 to the center of road 22
For clutch shaft bearing outer ring, the outer surface arc-shaped rail 22 places a circle bearing ball, and double raceway circle bodies are used as the
Two bearing inner races, the clutch shaft bearing and the second bearing form axial composite-rotor.
