Embodiment Construction

[0033] In the following description, the same reference numerals are used for the same types of components. It should be noted that the drawings are not drawn to scale as a whole and are primarily intended only to illustrate embodiments of the invention.

[0034] According to several preferred embodiments, Figure 1 to Figure 3A roll 1 and a roll drive 10 for the roll 1 of a fiber web machine are schematically shown. The roller 1 has a sheath part 2 and a shaft 3 fixed to the sheath part 2 by, for example, an end cap, and the shaft 3 is rotatably supported in a bearing housing 5 via a bearing 4 . The bearing housing 5 has a lubricating seal 6, and the lubricating seal 6 is arranged on both sides of the bearing 4 between the shaft 3 and the bearing housing 5 to prevent the lubricant (not shown in the figure) of the lubrication system from passing through the The insulating bushing for shaft 3 in body 5 is leaking. The bearing housing 5 is statically supported on the support F...

Abstract

The invention discloses a roller driver (10) for a fiber sheet machine, a sheath (2) of a roller (1) is rotated through shafts (3, 23), the shafts can be rotatably supported on a device support (F) through a bearing (4) arranged in a bearing housing (5); the roller driver is provided with a rotor housing (14) and a stator with a rotor winding, wherein the rotor (12) is arranged in the rotor housing (14); the roller driver comprises a rotor (11) rotatably acting on the shaft, the rotor is surrounded by the stator winding during operation so as to generate an air gap between the rotor and the stator. The rotor is permanently magnetized for achieving the large air gap; for fixing the rotor on the shaft, the rotor is designed that the shaft can support the mass of the rotor; for fixing the stator housing out of the bearing housing, the stator housing is designed for supporting the mass of the stator and the stator housing in a manner independent from the supporting manner of the rotor. The invention further relates to a roller equipped with the roller driver and a method for mounting the roller driver on the roller.

Description

technical field [0001] The invention relates to a roll for a fiber web machine, such as a paper, board, tissue or pulp machine; and a drive for such a roll. The invention relates in particular, but not exclusively, to a rotary drive of a roller in a fiber web machine or a corresponding roller-shaped component for processing a fiber web. Background technique [0002] Machine parts that rotate in a fiber web machine for processing a fiber web are eg rolls and rotating parts for rotating fabrics and belts. [0003] The rollers are usually mounted with both ends rotatably about their shaft / axis on fixed bearings. Bearings mounted on shafts are usually arranged in bearing housings, which in turn are secured to supports. [0004] It is known to use permanent magnet motors with hollow shafts as drive motors for paper machine rolls. Such a motor with a hollow shaft is arranged between the end of the roller shaft or between the bearing and the roller body, so that the shaft carrie...
