Definitions
- the invention relates to a drive of a felt guide roller of a drying group of paper machines.
- a felt or sieve additionally wraps around the paper guide rollers of the drying group together with the paper web in order to dry and guide it.
- the same possible speed of the felt and paper web must be ensured. It is therefore advisable to drive the felt or screen, in particular by means of a felt or screen guide roller. It is conceivable here to provide separate electric motors for such a drive. However, it is very expensive and it is difficult to establish the exact synchronization of the felt and paper web. This object is achieved according to the invention by the features of the characterizing part of protection claim 1.
- Fig. 1 in principle web and felt guide and Fig. 2 is a plan view, partly in section, of the area where the gear, the driven paper guide roller and the felt guide roller are located.
- Fig. 1 the end of the drying group is shown in principle, where the double-dashed paper web is guided over the guide rollers 1, 21, 22 and 41, of which guide roller 1 via toothed wheels 9 shown in dash-dot lines with their pitch circle, 10 and 11 of a countershaft gear is driven.
- the felt guide rollers are designated 2, 31, 32, 33 and 34.
- the felt is indicated by dash-dotted lines.
- the felt guide roller 2 of the upper run of the felt via pulleys 13 and 14 and belts 15 of the shaft 12 of the drive pinion 11 of the countershaft transmission is the closest to the gear mechanism or the paper guide roller 1 driven by the latter, which can also be a drying roller 6 driven, as follows from FIG. 2.
- the belt can be designed to be both smooth (flat) and as a multi-V or multi-V belt.
