A web drying unit, e.g. for a paper making machine, has several drying cylinders, over which a web to be dried can pass, and also several guide rolls for at least one endless supporting belt for pressing the web to be dried against the drying cylinders. Only some of the drying cylinders are provided with a drive gear connected by gears to a drive pinion, the gears being disposed inside a gear housing, which is also used to house cylinder journal pins for the drive motor. At least one of the guide rolls is also provided with a drive gear, which is connected to a drive gear of the drying cylinder. A gear housing also contains the drive gear of the guide roller and its bearing on the drive side. Only one common drive is needed for the unit, and uniform ventilation conditions are enabled to occur over the cross-direction of the paper web. To ensure no obstruction to maintenance personnel on the drive side of the unit, the drive pinion is disposed in the upper region of the gear housing. |
