A rolling-element bearing includes an inner ring and an outer ring having at least two adjacently disposed raceways for at least two rows of rolling elements. In order to avoid or reduce corrosion on the raceways of the outer ring caused by condensation forming on the outer raceway, the outer ring has at least one radially-outwardly-extending groove in the axial region between its at least two raceways for collecting condensation at a location away from the raceways.

In a paper or board machine drying line after the wire section, during dewatering a web's (W) width is affected in a direction crosswise to the web's traveling direction. Starting from an edge, at least one device (20A, 20B) brings about a force effect of a desired magnitude which is directed all the way to a desired arbitrary crosswise web position in order to modify web characteristics. A device in a paper or board machine line after the wire section has means for processing the web and for dewatering. The paper or board machine line after the wire section further has at least one device (20A; 20B) for directing a force effect at a desired partial area (WS) of the web (W) in the cross machine direction in order to modify the web's characteristics profile in the cross machine direction.

摘要:
An apparatus for manufacturing and/or treating a material web, in particular a paper or board web, having a roll with bearing journals which are provided at the ends, a roll frame having bearings, in which the roll is mounted with its bearing journals so as to be rotatable about its longitudinal axis, and having a motor which is plugged onto a bearing journal and is carried by the bearing journal, the motor being clamped with respect to the bearing journal in order to avoid roundness and vibration problems, the clamping length being at least one tenth of the length of the motor shaft. The invention also relates to a method for attaching a drive motor to a roll or for retrofitting the drive motor.

A drying section for a paper making machine includes a larger number of dryer sections, fewer dryers in each dryer section, and provisions for driving many of the dryers individually. The average number of dryers per dryer section is less than five and preferably less than four. By providing a small number of dryers per dryer section and driving many of the dryers individually, it is possible to more precisely compensate for stretching of the paper web in the initial stages of the drying process and to more precisely compensate for shrinkage of the paper web during the latter stages of the drying process.
摘要:
The invention is directed to a dryer section for an apparatus to produce a continuous material layer, such as paper, carton or cardboard. At least one dryer group has a plurality of dryer cylinders and guiding rollers. The dryer cylinders and guiding rollers carry the material layer along a meandering path, with each dryer cylinder and each guiding roller having a first side disposed on a same side of the dryer section. At least one mechanical drive mechanism is provided, with each drive mechanism being coupled with the first side of a dryer cylinder and/or guiding roller. A plurality of supply tubes are each connected with the first side of a corresponding dryer cylinder and/or guiding roller.
摘要:
A process for drying a paper web and a drying section of a paper making machine. The drying section includes at least one drying group comprised of a plurality of drying cylinders, each at least partially wrapped by a web to be dried. The drying cylinders having peripheral surfaces heated for drying the web moving therepast. The peripheral surfaces of the drying cylinders in the drying groups are rotated at the velocity of the web along the web path. At least one of the drying cylinders in at least one drying group is driven to rotate at a speed that is different than the speed of the web moving past the at least one cylinder. The at least one cylinder may be selectively driven to rotate faster or slower than the speed of the web moving therepast, which applies more heat to the paper web. The invention is adaptable for a single tier drying section and/or for a double tier drying sections or for other drying section arrangements. The operation of a drying cylinder at a different speed than the other cylinders is useful for one or more than one drying cylinder in a drying group and where a drying section is comprised of more than one drying group, is useful for a drying cylinder in one or more of the drying groups.
摘要:
A journal of a drying cylinder or the like, in a paper, cardboard or coating machine, is mounted in a bearing housing which is supported in fixed position on a frame. A hollow, cylindrically widened housing for an electric drive motor is formed as an extension of the bearing housing toward the drying cylinder. This motor housing, together with the bearing housing, forms a continuous outer surface for the drive system. The motor is a permanent-magnet motor whose stator has electromagnet poles which are arranged in the hollow cylindrical housing. Its rotor has permanent-magnet poles, which form a hollow cylindrical ring mounted on the circumference of the journal. The drive system consists of only a few parts, requires only a small amount of space for installation, and is easily and inexpensively serviceable.
摘要:
The drying cylinders of a paper machine drying cylinder block are provided with a joint driving system in which the pin of almost every drying cylinder is connected to a pin gear type reduction gear having a primary shaft positively connected to a drive shaft which is perpendicular to the cylinder pins and through a cone gear pair at one end of the primary shaft. In order to eliminate blind moments in the cylinder block there is provided an overload clutch in the form of a first flange fixed near the one end of the primary shaft, a second flange attached axially slidable at the one end of the primary shaft to define an annular recess with the first flange for receiving one cone gear of the cone gear pair, and means for pressing the one cone gear between the first and second flanges.
