3rd, the groove below undersetting flange and the lateral rocker cooperation that overarches so that upper bracket physical dimension is larger, dress
More than 70% is extremely difficult to rear contact area, monnolithic case size is larger, and manufacturing cost is high.
4th, concentricity and required precision are high when the groove below the sphere and flange of undersetting assembles, ball in running
Under face is acted on by locomotive load, track girder or bridge gravity load, active force caused by groove can not be eliminated or reduced, grown
Phase is vibrated and stress alternation effect easily occurs fatigue damage or stress concentration and cracked.
5th, there is a straddle-type monorail track camber beam of certain gradient, undersetting flange groove and compression chord on the inside of rocker,
Outside tension stress, abrasion is uneven to exacerbate the rate of wear;It is small to bear lateral torsion, can not be repaired after damage can only integrally more
Change.
A kind of eliminating or reducing stress collection for straddle type monorail rail tracks and bridge is not only suitable for therefore, it is necessary to develop
In and the permanent seal cooling bearing simple in construction for being easily assembled, dismantling.
The content of the invention
It is contemplated that the defects of overcoming above-mentioned bridge pad to exist, there is provided one kind loads and unloads castellated unstressed fixed ball soon
Bearing, the special operation condition that the bearing had both efficiently solved straddle type monorail rail tracks play a protective role to track girder, fit again
For bridge pad tension shearing resistance operating mode, and it is simple in construction, compact, bearing does not produce stress concentration, safe and reliable, service life
Length, cost are low.Assembly or disassembly simultaneously is convenient, is easy to field maintenance, changes.
The technical scheme that the present invention takes is:
One kind loads and unloads castellated unstressed fixed tumbler bearing soon, and the bearing includes upper bracket, spherical liner plate, sphere tetrafluoro
Slip ring, undersetting.It is characterized in that:The upper bracket of connection track girder is with four zigzag interior tooths and the band for connecting the case that casts anchor
The undersetting for having the outer tooth of four zigzag forms tension shearing resistance torsion resistant device together.The spherical liner plate being connected as a single entity with upper bracket
Form antivibration and alleviation together with the sphere tetrafluoro slip ring being embedded on undersetting or eliminate and answer power apparatus.
The spherical liner plate of the present invention is connected as a single entity with bolt and upper bracket.
Sphere tetrafluoro slip ring of the present invention is embedded in undersetting spherical groove, is connected as a single entity with it.
Unstressed, quick assembling of the invention and dismantlement work principle and its designing points are:
1st, by the spherical liner plate with upper bracket one and it is embedded in the sphere tetrafluoro slip ring of undersetting spherical groove
Relative slip between sliding pair, is reduced or eliminated the torsion between upper and lower bearing and vibration;
2nd, by the insertion of the notched teeth of upper and lower bearing, realize that straddle type monorail rail tracks are tilted to caused by bearing
Pulling force and shear stress;
