worm helical gear units Elevator gear units – a safe bet worm helical gear by AUMA Drives / GFC Whether as a passenger elevator or as a stage drive at the theater - our worm helical gear units are the right choice reagarding smoothness and low-noise performance. The first high-speed gear stage is implemented as worm gear stage ensuring homogeneous and low-noise torque transmission due to the outstanding noise absorbing properties and protecting the subsequent transmission elements from load peaks. The second stage consists of two helical, low-noise precision spur gears combining premium efficiency and soft start-up behaviour. elevator gear unit by AUMA Drives / GFC AUMA Drives worm helical gear units are operable in both rotation directions. Our worm helical gear units are provided for many connection and fastening options. The models are available in sizes 97, 118 and 150. 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 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 more than 20 standard transmission ratios per size models type SSVA: solid shaft at input, hollow shaft at output type SST_V: solid shaft with free shaft ends on one or both sides type SST_VF / SST_AF: output drive flange with solid shaft or hollow shaft
