Abstract
The invention discloses a ball bearing which comprises a floating ring, a fixed ring and a plurality of balls positioned between the floating ring and the fixed ring, wherein the floating ring is pre-tightened through an elastic component, and a rolling path of the floating ring, which is contacted with the balls, is in a truncated cone shape, so that better floating performance and low friction torque are brought.
Description
Technical field
The present invention relates to technical field of bearings more particularly to a kind of ball bearings.
Background technology
Deep groove ball bearing is widely used under the operating mode of the high and low friction of various rotating speeds.Usually in use, outer ring needs
It is pre-tightened to reduce noise and vibration characteristic by spring.Radial internal clearance is also required to according to concrete application environment, for example turn simultaneously
Speed is designed.That is, the radial internal clearance needs of deep-groove ball are specifically designed, without versatility.Meanwhile radial internal clearance also influences
The friction torque of bearing.
In the case where deep groove ball bearing is as floating bearing, it is limited to structure (arc-shaped, radian and the ball of ball receway
Radian it is close), when inner ring or outer ring expanded by heating, stretching, extension in an axial direction is subject to certain restrictions, and finally influences bearing
Service life.Moreover as previously mentioned, for different operating modes, it is also necessary to be specifically designed radial internal clearance, lead to the general of bearing
Property is not high.
Accordingly, it is desirable to provide a kind of improved ball bearing is to solve the above problems.
Invention content
The present invention solves the problems, such as to be to provide a kind of floating function admirable, the high ball bearing of versatility.
To solve the above problems, the present invention adopts the following technical scheme that：A kind of ball bearing, including floating ring, retainer plate and
If the dry bulb between the floating ring and retainer plate, the floating ring is pre-tightened by an elastomeric element, the floating
It is truncated cone shape to enclose the raceway contacted with ball.
As a further improvement on the present invention, the floating ring is outer ring, and the retainer plate is inner ring.
As a further improvement on the present invention, the outer ring is mounted on the inside of a housing, and the inner ring is mounted on an axis
On.
As a further improvement on the present invention, the housing has the flange extended towards axially inner side, the elastic portion
Part is mounted between the flange and the end face of the outer ring.
As a further improvement on the present invention, the elastomeric element is spiral helicine leaf spring.
Compared with prior art, the present invention has the following advantages：Floating performance more preferably, and has low friction torque.
Description of the drawings
Fig. 1 is the sectional view of ball bearing of the present invention.
Specific embodiment
As shown in Figure 1, ball bearing of the present invention includes outer ring 10, inner ring 20 and several between outer ring 10 and inner ring 20
Ball 30.
In the present embodiment, outer ring 10 as floating ring by the preload of an elastomeric element 40.Outer ring 10 is mounted on one
The inside of housing 50, and be loose fit between the two.The housing 50 has the flange 51 extended towards radially inner side, described
Elastomeric element 40 is mounted between flange 51 and the end face of outer ring 10.Inner ring 20 is mounted on axis 60 as retainer plate by tight fit
On.
Further, the raceway 11 that outer ring 10 is contacted with ball 30 is truncated cone shape.In this way, compared with prior art, axial floating
Ability be greatly improved；Meanwhile the use of ball bearing is no longer limited by radial internal clearance, the versatility with bigger；Again
Person contacts between ball 30 and raceway 11 for line, can be very good to reduce friction torque.
If 60 expanded by heating of axis, it will drive inner ring 20 to stretching, extension on the right side of Fig. 1, then ball 30 will be on raceway 11 easily
Ground slides, while elastomeric element 40 can also extend to adjust pretightning force, and ball bearing is made to reach an equilbrium position again.
Certainly, in other embodiments, can also outer ring as retainer plate, and inner ring is as floating ring, at this time truncated cone
Shape raceway is arranged on inner ring, while elastomeric element is also that inner ring is pre-tightened.Elastomeric element is preferably spiral helicine leaf spring.
Although the present invention is only described with regard to certain exemplary embodiments, these descriptions should be only as example without structure
Into limitation.In the range of the appended claims record, spirit and scope of the invention is not being departed from, various change is equal
It is possible.
