Abstract

The present invention relates to a fiber web treatment device (1) formed by a roller or cylinder. The fiber web treatment device has a shaft (3), an optional shaft extension (30) fixed on the shaft, and a motor (10) mounted on the shaft or the shaft extension. The motor is provided with a housing, a stator portion (12) fixed inside the housing and a rotor portion (11) mounted inside the stator portion. The rotor portion is provided with an inner end portion (71) near the shaft or the shaft extension and an outer end portion (72) far from the shaft or the shaft extension; inside the housing of the motor there is provided a supporting member for supporting the inner end portion and the outer end portion of the rotor portion; when the rotor portion and the stator portion are oppositely arranged at a first motor position along an axial direction, the stator portion and the rotor portion are spaced by a distance; and at the first motor position, the rotor portion and / or the stator portion is not supported by the external components of the motor. The present invention also relates to a method for mounting a motor with a hollow shaft on the shaft or the shaft extension of the fiber web treatment device.

Description

technical field [0001] The invention relates to a fibrous web-handling component, such as a roll or cylinder, and a method for mounting an electric motor equipped with a hollow shaft on a shaft or shaft extension of the fibrous web-handling component to be driven. Background technique [0002] In fibrous web production machines such as paper, board, tissue or pulp machines, rotatable fibrous web handling components are used, for example, comprising rolls, cylinders and drive elements, with which the Fabric or web movement. Typically, the roll is rotatably mounted on the machine table with its journals at both ends via bearings. Typically, the bearings assembled on the shaft are fixed in the bearing housing, and then the bearing housing is installed on the machine table. [0003] Drive motors for paper machine rolls are known as permanent magnet motors with hollow shafts. The hollow shaft motor is mounted at the end of the roll shaft or between the bearing and the roll bod...
