Unit version with fl exible coupling -A-

Model A

The easiest way of compensating for radial and angular misalignment between two shafts is to use a fl exible shaft coupling. The fl exible coupling can be installed and located either radially or axially. Belt-pulley version -R-

Model R

Where torque is transmitted through a V-belt, the belt groove or grooves can be machined in the drum. Single, duplex or multiple groo-ve pulleys can be produced in this way. De-pending on the clutch size, effective pulley diameters from ca. 80 to 270 mm can be in-corporated.Common groove forms are: SPA, SPB, SPZ, and Poly-V to DIN/EN. Figures 7 to 10 show different belt-drive clutch versions. The clutch shown in Fig. 9 with a split pulley allows elimination of a tensioning pulley. The V-belt is tensioned by changing the spacer shims between the two pulley halves. Fig. 9 Fig. 10 Fig. 7 Fig. 8 Fig. 6
