Abstract: A spur gear transmission has at least two meshing, toothed spur gears. A covering wall surrounds the spur gears circumferentially and in the direction of their rotational axes. The covering wall has an inner contour adapted to the outer diameters of the spur gears. Two annular gaps which transition into each other are formed between the covering wall and the spur gears. The annular gap is substantially concentric to a rotational axis. The covering wall surrounds the two spur gears circumferentially only over a part of the circumference, with a part of the outer circumference of the two spur gears or one of the two spur gears protruding outwards out of the covering wall. The part of the two spur gears or of the one spur gear that protrudes out of the covering wall is positioned on the lower face of the spur gears.

Abstract: The invention relates to a spur gear transmission with at least two intermeshing spur gears the teeth of which are in meshing engagement with one another, and each of which are rotatable via an axis of rotation. The spur gear transmission has an enveloping wall which surrounds the two spur gears in circumferential direction and in the direction of the axes of rotation. The enveloping wall has an inner contour which is adapted to the outer diameter of the spur gears in such a manner that two annular gaps which merge into each other are formed between the enveloping wall and the spur gears. One annular gap respectively is arranged at least substantially concentrically with respect to a respective axis of rotation. The enveloping wall is formed by a two-part housing which is closed along a parting line and which has an upper part and a lower part.

Abstract: A drive device includes a speed modulation gearbox having a planetary gear mechanism and a casing, a main drive machine which is connected to an input shaft of the speed modulation gearbox, two auxiliary drives, each connected to the planetary gear mechanism via a drive connection. An output shaft of the speed modulation gearbox can be connected to a working machine. The planetary gear mechanism includes a ring gear, a sun gear, a planet carrier and several planet gears. For each auxiliary drive, an additional drive connection with a constant transmission ratio exists between the auxiliary drives and the input shaft or between the auxiliary drives and a driven shaft of the planetary gear mechanism. The additional drive connections can each be engaged or disengaged by a respective switching clutch, wherein the drive connections from the auxiliary drives to the speed modulation gearbox remain engaged in any case.

Abstract: A shaking unit for the generation of one-dimensional oscillating movements of a machine part mass is provided having a coupling part for mechanical coupling to the machine part mass, a counter-mass which is coupled resiliently to the coupler part and, via the latter, to the machine part mass, and a drive system which acts in a sprung manner between the coupler part and the counter-mass. The coupling part may surround the counter-mass as a frame. At least one of two pneumatic springs of the drive system, which are arranged on both sides of the counter-mass, is loaded with a minimum and/or with a maximum load pressure of the pneumatic springs depending on an oscillation state.

Abstract: A press jacket includes at least one polymer layer. The polymer layer includes, or has been produced from, a polyurethane. The polyurethane has been formed from a prepolymer and a cross linking agent. The prepolymer is a reaction product of phenylene 1,4-diisocyanate and a polyol. The cross linking agent includes the following components: a first component including 1,4-butanediol or 1,4-hydroquinone bis(2-hydroxyethyl) ether (HQEE), a second component including at least one aliphatic diamine, and a third component including at least one alkanolamine. A press roll, a shoe press and a process for the production of a press jacket are also provided.

Abstract: A method for manufacturing a large-cylinder drying roller includes providing a cylindrical cylinder shell having two sides, initially attaching a respective cap to each of the sides of the cylinder shell, subsequently inserting an inner shaft coaxially within the cylinder shell and connecting the inner shaft to the caps and connecting journals to the inner shaft. The inner shaft is divided into two inner-shaft parts. Each inner-shaft part is inserted from a respective side and then each of the inner-shaft parts is connected to the other of the inner-shaft parts and to a respective one of the caps and/or prior to inserting the inner shaft, the cylinder shell and the caps are relieved of stress and the connection of the cylinder shell and the caps is checked from the inside or the cylinder shell and/or the caps are mechanically processed together.

Abstract: A dryer filtration fabric for use in a drying section of a machine for producing and/or processing a fibrous web, in particular paper, cardboard, tissue or non-woven, has machine direction threads interwoven with machine cross direction threads to form a single-ply woven fabric having an air permeability between 40 cfm and 330 cfm. The machine direction threads and the machine cross direction threads have a flattened cross-sectional shape with a width-to-height ratio of more than 1. Each of the machine direction threads runs over and/or under a maximum of three, preferably a maximum of two, machine cross direction threads that are disposed directly beside one another. The number of the machine direction threads per 10 cm, viewed in the machine cross direction, lies in the range from 170 to 200, and the filling level of the machine direction threads lies in the range from 90% to 110%.

Abstract: The invention relates to a press for a machine for producing a fibrous material web, including at least one press nip formed between a press roller and a counter press roller of the press for guiding through the fibrous material web in a dehydrating manner, and two band shaped covers, which are each guided by multiple guide rollers in continuous circulation, so as to run together through the press nip, so that the fibrous material web is guided through sandwiched between said covers, and then separated again at a separation point, in order to continue guiding the fibrous material web on the one cover and separate it from the other cover. One guide roller of the guide rollers arranged at the separation point is a suctioned guide roller of the one cover, to hold the fibrous material web on the one cover at the separation position.
