Gearbox for duty load and cabin speed up to 1.200kg – 2m/s.
Very compact and functional machine specially designed for up to 1200 Kg duty load and speed up to 2 m/s, with rotor directly mounted on worm shaft, without connection fittings (A4) and hand wheel directly placed onto the motor. The body of the gear box is made into two parts: upper and lower. Worm shaft running on utmost quality ball bearings for the axial constrain. Worm wheel, running on roller bearings, is made by special alloy (centrifuged bronze with nickel) and traction sheave is made by spheroid cast iron (EN-GJS-700-2 UNI EN 1563). HW175 is characterized by very high efficiency, carbon hardened, worm shaft with special surface treatment of flanks. Delivered with synthetic oil (8,5 litres) and standard single-phase 230V- 50Hz fan, it has cantilever sheave (two fixation points). Outstanding characteristic is the possibility to completely disassemble the machine into subcomponents (motor, flywheel, brake, sheave) for transportation, handling and installation in otherwise not easily accessible sites. Noise level below 60 dB (complying with IEC 39-4; CEI EN 60034-9), horizontal vibration level minor than 0,7 mm/s (complying with IEC 34-14; CEI 2-23) and electromagnetic brake with independent double action are characteristics that position GEM HW175 machine as the avant-garde of the gearbox technology.
