taipumasäädettävä roller and method taipumasäädettävän track load adjusting

摘要

The invention relates to a controllable deflection roller and a method for controlling a controllable deflection roller. In the hydraulic load element 10, 10a of the controllable deflection roller, a continuous loading directed opposite relative to the direction of load of the hydraulic load elements is arranged, said loading together with a desired nip pressure determining the magnitude of the loading pressure of the hydraulic loading elements 10a. According to the invention, the loading elements are designed in such a way that the effective surface A1 of the hydraulic pockets on the loading shoe is substantially the same size as the inner surface A2 of the loading shoe. In this way, as the counter pressure P3 is constant, the oil flow flowing through the shoe is kept constant as well. IMAGE
