The case where, but the invention is not restricted to this.The present invention may include that multiple groups pretension bolt and pre- is arranged in the circumferential direction of cantilevered axle
The case where tight spring, as long as the multiple groups pretension bolt and preloading spring need size and side in capable of radially generating for cantilevered axle
To pretightning force.
(6) in addition, by the way that preloading spring is located in different circumferential positions and by using the preload bullet of different number
Spring, the pressure for making different preloading springs using the preloading spring with different spring constants and and tightening and unscrewing pretension bolt
Contracting grade difference adjusts the direction of pretightning force.For example, can be by the way of the circumferentially-spaced certain angle in cantilevered axle
It is arranged that two groups of pretension bolts and preloading spring, making the spring constants of the two preloading springs, equal way to set does not pre-tighten dress
It sets.
(7) it is disclosed in a specific embodiment of the invention using preloading spring as pretightning force generating means and openly
The regulating device being adjusted for compression degree to preloading spring is pretension bolt, and but the invention is not restricted to this.Example
Such as, the elastomer appropriate (for example, spring washer, rubber etc.) in addition to spring can be used to replace preloading spring, it can be with
Preloading spring is fixed using plug, pin etc..
Using technology of the invention, can be effectively prevented from operation process leads to radial direction due to skidding
The risk that bearing breaks down；The load distribution between the transverse bearing arranged side by side can be improved；It can be improved cantilevered axle
The rigidity of structure.And it requires no longer to be the limitation in the selection of system or equipment design process middle (center) bearing due to bearing minimum load
Parameter, therefore the rigidity by the way that cantilever shaft structure can be further increased using biggish bearing in the position.
Protection scope of the present invention is not limited to above-mentioned specific embodiment, as long as but meeting claim of the invention
The combination of feature is just fallen into protection scope of the present invention.
