The Siemens Drive Technologies Division is supplementing its Motox geared motors with a new range of worm gears; they are particularly suitable for conveyor systems (Fig.). The single-stage worm geared motor of the S range is available in the three frame sizes S08, S18 and S28, in a torque range from 18 to 80 Nm and in a power range from 0.12 to 0.75 kW (4-pole). Installation can take shaft-mounted, foot-mounted or flange-mounted form. The input shaft is available either solid or hollow. The use of high-grade materials allows high rated gear torques up to 80 Nm and high transmission ratios of up to 100 in a single stage. The worm shafts are case-hardened and ground, which makes running quieter. A strong radial force is achieved by high-grade roller bearings and greater distances between bearings. The tooth root security of the Cavex concave-profile teeth allows high load peaks. The gears are maintenance-free due to lubrication-for-life with synthetic oil, as well as high-grade bearings and seals.
