Helical worm gear units are used to safely lift and lower loads and are ideally suited for applications in continuous duty. The combination of a worm gearing with an upstream helical gear stage provide the advantages of both gearing types. helical worm gear by AUMA Drives / GFC On the one hand, the two stages allow for large transmission ratio ranges, on the other hand, it combines high efficiency levels and torques with highest lifetime and reliability within a compact drive. This is extremely efficient in terms of space, cost and reduced maintenance efforts. AUMA Drives helical worm gear units are operable in both rotation directions. Our helical worm gear units are provided for many connection and fastening options. The models are available in sizes 50, 63, 80, 100, 125 and 160. Technical data on each size is provided on request. The basic variant type SSVA can be extended by drive and motor flanges, covers and many further options, such as slip-on output drive shafts. design features worm wheel 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 more than 20 standard transmission ratios per size models type SSVA: solid shaft at input, hollow shaft at output type SS_V: solid shaft with free shaft ends on one or both sides type SS_VF / SS_AF: output drive flange with solid shaft or hollow shaft type SSK: coupling flanges for IEC motors
