Embodiment Construction

[0031] The roll system, marked as a whole with 100 in the figures, comprises a roll 1 which is Figure 1 to Figure 5 In the exemplary embodiment shown, it is formed as a hydraulically internally supported roller. The rollers each comprise a shaft 2 , which is mounted in a rotationally fixed manner at least on the drive side shown in the drawing via self-aligning bearings 3 . The self-aligning bearings form each bearing point T for the shaft 2 .

[0032] exist Figure 6 In the embodiment shown in , the roller 1' is configured as a conventional roller. Its roller body 5' is non-rotatably connected to a shaft part 6, which is mounted on the drive side via a rotary bearing 7 in the bearing device 4'. The pivot bearing 7 forms the bearing point T here.

[0033] In the roller system according to the invention in the Figure 1 to Figure 5 In the exemplary embodiment shown in , the roller body 5 comprises a hollow cylinder 8 which rotatably surrounds the shaft 2 while retaining t...

Abstract

The invention relates to a roll arrangement (100) comprising a roll (1, 1') which has an axle (2) or shaft (6) received on a bearing (T). Said arrangement comprises a roll body (5, 5') defining the working periphery of the roll (1, 1') and being rotatable about an axis of rotation (D), and an electromotive direct drive (50) the rotor (13) and stator (15) of which is arranged between the bearing (T) and the roll body (5, 5') in the direction of the axis of rotation (D). The stator (15) is subdivided into stator segments (17) in at least one plane (E) that is parallel or at an angle to the axis of rotation (D). The stator segments (17) are received such that respective first ends thereof can be swiveled about hinge axes (S) that extend approximately in parallel to the axis of rotation (D).

Description

technical field [0001] The invention relates to a roller system comprising: a roller comprising a shaft or a shaft element supported on a bearing point; a roller body forming the working circumference of the roller, said roller body being rotatable about an axis of rotation; and an electric motor A direct drive whose rotor and stator are arranged in the direction of the axis of rotation between the bearing and the roller body, and the invention also relates to a mounting method for such a roller. Background technique [0002] Such a roller system is known from DE 103 39 733 A1. In said roll system, the rotor of the electric direct drive is fixedly connected to a roll trunnion which is set back relative to the working circumference of the roll. The stator of the electric direct drive, which retains an annular gap relative to the rotor, is arranged in the motor housing, which is supported by means of its own housing bearing on a shaft that delimits the axis of rotation of the...
