Standard worm gearboxes
Due to its mode of operation, a worm gears with large gear ratios allow a very high reduction in speed. With worm gears, the two shafts cross at a defined distance (A). This center distance is reflected in the gearbox specification. (Example: S 100 – centre distance 100 mm)
Worm gears are high-precision and rugged offset gears. These
high-performance gears meet the high demands every time and in every respect.
They are quiet and not so sensitive to impacts. It is not without reason that
they are used in conveyor systems worldwide, amongst other things.
