Abstract
The utility model discloses a kind of vibration damper joint shaft bearing, comprise outer ring, inner ring, base, the internal surface of this outer ring and the outer surface of this inner ring form the sliding motion structure cooperatively interacted, this outer ring is installed on the base, the middle part of inner ring axial running through is provided with through hole, mandrel is through described through hole, also comprise two shock absorbing sleeves and two locating pieces, described two shock absorbing sleeves to be set on this mandrel and to lay respectively at the both sides of this inner ring, and described two locating pieces apply axial forces to two shock absorbing sleeves respectively thus make two shock absorbing sleeves clamp described inner ring.Described two locating pieces apply axial force to two shock absorbing sleeves respectively thus make two shock absorbing sleeve axial clamp residences state inner ring, can eliminate the axial internal clearance of joint shaft bearing, reduce vibrations, anti-snakelike, thus improve the driving comfort of train.
Description
Technical field
The utility model relates to a kind of vibration damper joint shaft bearing, particularly relates to a kind of joint shaft bearing of high ferro vibration damper.
Background technique
Joint shaft bearing can be divided into several form such as integral outer ring's joint shaft bearing, double semi outer rings joint shaft bearing, single seam outer ring joint shaft bearing structural type.Because the inner ring of existing joint shaft bearing and outer ring all adopt single curvature structure form, and joint shaft bearing is not a complete sphere-contact, the problem that such axial internal clearance is larger than radial internal clearance just there will be, and general axial internal clearance is 2-3 times of radial internal clearance.Therefore, mostly there is the large technical problem of axial internal clearance in existing joint shaft bearing, and this will directly cause inner ring axial float, produces larger noise, affect the driving comfort of high ferro.
Model utility content
The utility model provides a kind of vibration damper joint shaft bearing, which overcomes the deficiency existing for background technique.The utility model solves the technological scheme that its technical problem adopts:
A kind of vibration damper joint shaft bearing, comprise outer ring, inner ring, base, the internal surface of this outer ring and the outer surface of this inner ring form the sliding motion structure cooperatively interacted, this outer ring is installed on the base, the middle part of inner ring axial running through is provided with through hole, mandrel is through described through hole, also comprise two shock absorbing sleeves and two locating pieces, described two shock absorbing sleeves to be set on this mandrel and to lay respectively at the both sides of this inner ring, and described two locating pieces apply axial forces to two shock absorbing sleeves respectively thus make two shock absorbing sleeves clamp described inner ring.
Among one preferred embodiment: described shock absorbing sleeve has the arc contact surface matched with the outer surface of this inner ring.
Among one preferred embodiment: the width of described outer ring is less than the width of described base, described datum axle is provided with mounting hole to running through, and described outer ring is positioned at the middle part of described mounting hole, and the outer surface of described shock absorbing sleeve abuts with the sidewall of described mounting hole.
Among one preferred embodiment: also comprise two back-up rings, described two back-up rings to be embedded in described mounting hole and to clamp described outer ring.
Among one preferred embodiment: described locating piece structure being set on described mandrel in the form of a ring.
Among one preferred embodiment: the inner shafts of described locating piece is provided with bulge loop to extending internally, and described bulge loop is centered around the outer surface of described mandrel, and described bulge loop abuts with described inner ring.
Among one preferred embodiment: describedly also comprise two baffle rings, described two baffle rings to be embedded on described mandrel and axially to push down described two locating pieces respectively.
The technical program is compared with background technique, and its tool has the following advantages:
1. described in, two locating pieces apply axial force to two shock absorbing sleeves respectively thus make two shock absorbing sleeve axial clamp residences state inner ring, can eliminate the axial internal clearance of joint shaft bearing, reduce vibrations, anti-snakelike, thus improve the driving comfort of train.
2. shock absorbing sleeve described in has the arc contact surface matched with the outer surface of this inner ring, improves the fitment stability of shock absorbing sleeve and inner ring.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 depicts the cross-sectional schematic of a kind of vibration damper joint shaft bearing of the utility model.
