Description
Technical field
The utility model relates to a kind of bridge pad, particularly a kind of hinge slide plate bearing.
Background technology
What traditional hinge (roll shaft) bearing generally adopted is steel support, and support displacement by the roll shafts scrolling realization onboard of arranging more, and its power transmission is clear and definite, the power transmission efficiency height, but owing to line contact power transmission, length travel rubbing surface contact stress is quite big.The height of general requirements bearing is higher, alleviates the fatigue failure that this bigger contact stress produces.In addition, the increase of height of support need be adopted an effective measure and be avoided the generation of unstable phenomenon, abroad, generally be that rotating hinge is carried out specially treated, by adopting the advanced antifriction material resistance of reducing friction, thereby the moment of resistance of reducing friction is to the scope of design control, and requirement checks the phenomenon of avoiding toppling generation to bearing stability; At home, often not enough to the issuable unstable phenomenon attention degree of this higher bearing, the design of rotating hinge haves much room for improvement, and the comprehensive mechanical performance of the case hardness of rolling surface, fineness and material therefor and corrosion resistance all should give strict control.
Common slide type hinge support has changed the mode of transfer force of line contact, new material and new technology on the in-plane displancement friction pair, have been adopted, but this contact mode of transfer force is different with roll axis contact mode of transfer force, face contact mode of transfer force is to determine a kind of suitable height of support by mechanical analysis calculating, finite element method and test etc., this height should have reduction by a relatively large margin on the basis of traditional hinge (roll shaft) bearing, to strengthen the stability of bearing.In fact, the height of this bearing does not reduce with respect to the height of traditional hinge (roll shaft) bearing, and the secondary design of pivoting friction is comparatively simple again, the moment of friction that acts on the displacement surface is bigger, and the stress at sliding material edge is bigger, causes this kind hinge support less stable.
Application number is 03257817.2, the applying date is on June 10th, 2003, name is called the Chinese utility model patent of hinge slide plate steel support, a kind of hinge slide plate steel support is disclosed, the bearing bottom and a seat board are replaced by tetrafluoroethene plate and corrosion resistant plate friction pair, slide flexibly though have, characteristics such as easy maintenance, but this kind roller support is still realized the displacement of bearing by the rolling of roll shaft, along with the bearing increase of service time, each friction pair all can constantly wear and tear, and the inhomogeneous rolling of roll shaft occurs, causes connector to bear bigger additional force and is out of shape and damages, the roll shaft inclination angle is further strengthened even is toppled over, and bearing can't be exercised its normal function.
