Square acts on linear actuators 30.
Unlike the prior art, that is, if the combination for acting on the arrow F of identical linear actuators 30 generates tilting moment
(referring to Fig. 1), then the tangential force T generated in rolling-mill housing 10 can set the presence of element 20 without generating tilting moment because between
(referring to fig. 4).
Element 20 is set between being inserted between first roll bearing block 40 and linear actuators 30, allows to discharge tangential force T, is prevented
Only active force is loaded into linear actuators 30, to avoid the generation of tilting moment.
Compared with acting in the tangential stress that support roller 24 opposite end in bottom provides the first roll bearing block 40 of support,
The tangential force T substantially size for acting on first roll bearing block 40 is identical, and has opposite direction.This can cancel out each other
The tangential force T that element 20 absorbs is set by between completely.Such case acts on substantially and in bottom support roller 24 in distributed load L
Occur more when in symmetrical bottom support roller 24.This stress condition avoids having to and sets between being provided with element 20
Laterally contain device joint, to prevent from setting element 20 and generating between the direction horizontal transfer parallel with rotation axis line X
Tangential force T.
According to variant, setting element 20 must not translate along the direction parallel with rotation axis X, and only along vertical axis
Direction vertical shift acts axially on linear actuators 30 to allow to discharge, that is, is parallel to the stress of the direction D.
Some conceptions according to the present invention, if the load for acting on its surface is unequal, it is proposed that, set element 20
It is arranged and laterally contains element to set the transverse shifting that element 20 may be generated by tangential stress between accommodating.
According to using variant described in Fig. 5, set element 20 can be only allowed in the direction D parallel direction it is mobile between
Set element 20 and in the receiving and guiding for preventing it from moving with rotation axis X parallel direction or different from the direction of the direction D
Element 46 is associated.The receiving and director element 46 are mountable in support construction 25, so that setting element 20 between allowing to discharge can
The shearing stress T that can be subject to.Although describing the presence of receiving and director element 46 with reference to structure shown in Fig. 2 to Fig. 5,
