AUMA Drives worm gear units are operable in both rotation directions. Our worm gear units are provided for many connection and fastening options. The models are available in sizes 40, 50, 63, 80, 100, 125, 160, 200, 225, 250, 280, 315, 355, 400 and 450. Technical data on each size is provided on request. The basic variant type SVA can be extended by drive and motor flanges, covers and many further options, such as slip-on output drive shafts. By combining two single-stage worm gear units, significant speed reduction can be achieved in spite of the smaller and compact design. Due to the high transmission ratios (up to i > 5000) , the relatively low drive performance is converted into high torques, particularly paying off for strong intermittent duty such as positioning duties. We provide double worm gear units and worm gear units in various sizes and designs, featured by highest transmission ratios. Helical worm gear units can be implemented as primary reduction gearings, thus achieving a total transmission of i > 10.000 – please contact us! design features worm gear set according to DIN 3975, flank shape ZK, worm shaft made of 16MnCrS5, case-hardened and grinded worm wheel made of highly wear resistant special bronze lubrication: fully synthetic oil for highest efficiency and reduced maintenance quality roller bearings for highest lifetime and absorption of external forces 10 standard transmission ratios per size, more available on request
