DG Series – Shaft Mounted Helical Gearboxes

DG Series – Shaft Mounted Helical Gearboxes

DG series, shaft mounted gearboxes are specially designed for belt conveyors. Thanks to their rigid structure, they are suitable to operate reliably even in harshest conditions such as mines and quarries. DG series gearboxes are produced in twelve different sizes and offer easy mounting and flexible connection options.

DG series gearboxes are offered with or without motor. The gearboxes without motor are usually driven by belt-pulley systems. If needed, they are manufactured with back-stops to prevent back running of inclined conveyors.

Housing material is GG20 cast iron. Gears are produced from high quality, case hardened steel. Heat treatment process is applied to obtain 58-60 HRC surface hardness. The gears are precision ground to ensure a quiet and low vibration operation. Special oil seal options are available for dusty operation conditions.
