Badoni s.r.l. designs and realizes speed reducers (parallel shafts, right angle shafts, planetary) for big powers having the following technical characteristics:
case: made of steel plates welded together, with air breather, inspection doors and hooks for hoisting;
gears: pinions and wheels are made of nickel-chrome-molybdenum case-hardened alloy-steel or hardened and tempered steel, with profile finished as appropriate after heat treatment;
shafts: made of steel, hardened and tempered, if not designed as a unique piece with pinions;
bearings: all bearings are designed for extremely long running life, anti-friction type, top quality;
lubrication: by oil splash, forced lubrication whenever specified (highlighted areas);
rotation: both clockwise and counter-clockwise rotations are always possible.


Our reducers are rated in accordance to AGMA standards. To select a reducer the following data must be known:
absorbed power of the driven machine;
rotating speed and specifications of the driving machine;
rotating speed and specifications of the driven machine;
duty cycle;
room temperature;
shaft arrangement.


All reducers are subjected to an operating test “on unload conditions” for the necessary time.
Upon request we submit a test certificate which, besides the operating feauters, includes the following:

Request a catalog

Bearing clearance;
Toothing clearances and contact %;
Noise and vibration level;
Temperature measurements;
Control of oil gaskets;
Control of oil pressure on reducers fitted with such equipment.


We usually submit certificates for chemical analysis and mechanical tests on materials (steel works).
