Definitions

  • the invention relates to a shaking device for reciprocating a roller along an axis thereof, in particular a roller for a machine for producing a fibrous web, in particular a paper, cardboard or packaging paper web, a first, connected to the roller in the direction of the roll axis Eccentric drive and a second, connected to the roller in the direction of the roller axis eccentric drive, wherein the two eccentric drives are driven by at least one motor, preferably two motors, wherein the two eccentric mounted on or in a common and movable or movable device are, and wherein the roller and the device by means of at least one at least one-part Scdazzlinglstange are connected directly or indirectly.
  • Such a shaking device is for example from the document EP 1 624 102 B1 known.
  • This largely reaction-free working shaking is based on directly driven mass pairs by means of highly dynamic three-phase drives with angular tracking control, the mass pairs are arranged in a hydrostatically mounted device, such as a carriage, a frame or a frame.
  • a hydrostatically mounted device such as a carriage, a frame or a frame.
  • the two mass pairs of such a shaking device can also be driven by means of a drive device having only one drive motor.
  • an electric motor and a hydraulic motor can be used.
  • the transmission of the rotational energy generated by means of the shaker on an exemplary breast roll of a machine for producing a fibrous web is a system oscillating in a horizontal direction - with a common mechanical zero point.
  • the breaking length ratio in the fibrous web to be produced can be freely selected within wide limits.
  • a disadvantage of this known shaking device are the rigid, possibly also articulated connections between the roller to be moved and the movable device which supports the two eccentric drives.
  • the rigid connections are subject to deflections, vibrations, wear and the like.
  • rigid connections have, for example, high internal stresses and loads and cause high lateral forces both in the bearing units of the movable device and at the other end, namely on the roller to be moved.
  • they require high and only with great time achievable alignment accuracies. Premature failure of the bearings, especially the main bearings of the shaker and / or the breast roller bearings is a regular consequence.
  • connection between the roller and the device comprises at least one at least temporarily fixable, in particular clampable ball joint.
  • connection according to the invention between the roller to be moved and the movable device by means of at least one at least temporarily fixable in particular clampable ball joint ensures a largely axial power transmission and effectively avoids the transmission of adverse lateral forces. And the previous requirement of high alignment accuracy is significantly reduced even in the case of a readjustment of the two units roller and device.

  • the at least temporary fixation, in particular clamping of the ball joint preferably takes place on at least two spherical and preferably diametrically arranged spherical partial surfaces of the ball of the ball joint.
  • an intermediate piece with a preferably cylindrical or crowned basic shape is preferably formed between the two spherical and preferably diametrically arranged spherical partial surfaces of the ball of the ball joint, wherein the basic shape has a maximum diameter in the range of 40 to 80%, preferably from 45 to 75%, in particular of 50 to 70%, of the ball diameter of the ball of the ball joint.
  • the at least temporary fixation, in particular clamping of the ball joint, in particular on the at least two spherical and preferably diametrically arranged spherical partial surfaces of the ball of the ball joint takes place at least on one side, preferably two sides.
  • a one-sided fixation, in particular clamping can be done for example by means of a bolt or the like, a two-sided fixation, in particular clamping, however, for example by means of at least two clamping units.
