Definitions

  • the invention relates to a device for supporting a shaft, in particular for supporting a roller of a paper machine, with a radial bearing supporting the shaft on both sides, with a housing receiving the radial bearing and with a support locking the housing to the bottom.
  • the electric motor is attached to a free end of the roller and is operatively connected to it, so that the roller is driven by the electric motor.

  • the second housing part In order to be able to repair a faulty electric motor, it is arranged in the second housing part and is accessible via an opening provided in the second housing part, so that the components of the electric motor can be inserted or executed through this opening.
  • Radial bearing is supported. Possible deflections of the free end of the shaft are not present either with regard to the mechanical load on the radial bearing or the functioning of the electric motor, because the distance between the stator and the rotor of the electric motor is either designed such that the calculated deflection of the shaft by the specified distance is taken into account, or the radial bearing or the housing are additionally supported in a spherically curved slide bearing, by means of which the deflection of the free ends of the shaft is compensated for.

  • a housing jacket 22 is detachably connected to the first housing part 16 and partially or completely surrounds the second housing part.
  • the functioning of the device 1 according to the invention is that the radial bearing 3 is held on both sides of the shaft 2 by the first housing part 16 and the support 5 on the bottom 6. Due to the high weight of the shaft 2 and the mechanical load during operation of the paper machine, the shaft 2 r bends parabolically in the direction of the bottom 6 and through the two intersections of the central axis 7 and the axis 8, so that the free ends of the Wave 2 are raised on both sides from the theoretical middle position.
  • the electric motor 12 is supported via the radial bearing 3 and the hollow shaft 11, so that it is held in a floating manner by the radial bearing 3.
  • the deflection of the free end of the shaft 2 is taken into account before the electric motor 12 is installed in such a way that the air gap between the rotor 13 and the stator 14, which is present in the preassembled state, is dimensioned large enough so that the deflection of the shaft 2 is absorbed by the existing air gap becomes.
  • the deflection and thus the deflection of the shaft 2 can be precisely calculated in advance, so that due to the known geometry of the electric motor 12 with regard to the mounting on the hollow shaft 11 and the distance to the central axis 7 of the rolling bearing 3, it is taken into account that in the operating state the paper machine, that is, the rotation of the shaft 2, the air gap between the rotor 13 and the stator 14 corresponds to the optimal distance originally to be provided at least in the region of the deflection.

  • the outer contour of the first housing part 16 or of the housing shell 22 is, according to FIG. 3, quadrangular and, according to FIG. 4, quadrangular or hexagonal for the housings 4 spaced from the floor 6.
  • the housings 4 are thus mutually supported, so that, since this arrangement on both Side of the shaft 2 is provided, the shaft 2 is supported as a whole. Especially with the square outer contour of the housing, optimal horizontal alignment and positioning is possible.
  • the electric motor 12 driving the shaft 2 can take over the drive of the shaft 2, so that the paper machine as a whole cannot be shut down, but can continue to operate undisturbed.
  • the cover 19, which closes the outlet opening 18 of the second housing part 17, is removed in the faulty electric motor 12, so that, for example, the stator 14 can be removed from the housing 4 and replaced without the paper machine having to be completely dismantled because the Composite of mutually supporting housing 4 remains unchanged.
  • FIGS. 5 and 6 how two adjacent housings 4 are aligned and fastened exactly in alignment with one another, both laterally and one above the other.
  • one or more recesses 23 are machined in the outer circumference of the first housing part 16 or in the housing jacket 22, which are trapezoidal in cross section. If two housings 4 are to be connected to one another, as shown in FIG. 5, the recesses 23 of the two adjacent housings 4 are to be aligned with one another. In such a completely closed recess 23, a rod 24 can be inserted, which rests on the inside of the recesses 23.
  • the cross section of the rod 24 corresponds to the cross section of the recesses 23, so that the outside of the rod 24 on the inside of the recesses 23 is applied. Due to the trapezoidal design of the recesses 23, the rod 24 centers the two adjacent housing parts 16 to one another.
  • the recesses 23 machined into the housing 4 run perpendicular to one another, so that there is an attachment possibility in every horizontal and vertical direction of movement by inserting rods 24.
  • the rods 24 can be inserted over the entire length of the recesses 23 or only partially.
  • the stacked arrangement of housings 4 is an immovable but detachable connection, which can be separated from one another by pulling the rods 24 out of the respective Ausnehrivdf.gen 23.
  • Such a stacked arrangement of housings 4 can, for example, also be built up on an inclined plane, as shown in FIG. 4.
  • the outer contour, in particular of the housing part 16, is polygonal, depending on the particular application or the locking options between adjacent housings 4.
  • the housings 4 can also be fastened to one another via intermediate members, so that the connection of the housing 4 together with the possible intermediate members as Serve 5.
  • FIG. 7 shows the device 1, which is now additionally held by a spherically curved slide bearing 32, so that the deflection of the free end of the shaft 2 is absorbed due to the possibility of movement of the spherical slide bearing 32. It is therefore no longer necessary for an air gap between the rotor 13 and the stator 14 of the electric motor 12 to be dimensioned such that the deflection of the free end of the shaft 2 is taken into account. Rather, the bending line of the shaft 2 is received in the spherically curved slide bearing 32.
  • FIG. 7 shows two different variants of the plain bearing 32. In detail:
  • the outer ring 31 of the radial bearing 3 is spherically curved.
  • the wall of the housing 4 supporting the outer ring 31 corresponds to the spherical curvature of the outer ring 31, so that the radial bearing 3 is arranged in the spherically curved slide bearing 32.
  • the spherical slide bearing 32 is arranged on the outer circumference of the housing 4, as is shown in the upper half of FIG. 7.
  • the housing 4 consists of two additional rings 35 and 36 which are connected to one another in the region of the second housing part 17.
  • the second housing part 17 has a conical outer circumferential surface 33 which tapers in the direction of the shaft 2.
  • the first ring 35 has a corresponding inner lateral surface 34, so that the second housing part 17 and the first ring 35 can be pushed into one another, so that the second housing part 17 can be removed from the fixed ring 35.
  • the outer circumferential surface of the first ring 35 is spherically curved, so that the second ring 36, which consists of two halves, can be pushed laterally onto the first ring 35.
  • the slide bearing 32 is thus formed, because the two ring halves are screwed together in the corner regions, which are not shown.
