Speed reducer: Power 1.115 Kw - Input speed: 1.200 r.p.m 1 – Out 6 r.p.m.

Special speed reducer STD 34.1 for sugar mill

-Reducer at parallel axis with automatic balancing of the loads on the toothings, with gears in alloy casehardened steel (carburized) with the profile of teeth ground and duly relieved to reduce possible load concentrations.
-Casing in electrowelded steel at perfect oil tight, shaped and ribbed to increase at maximum its rigidity. After welding, the casing will be submitted to stress relieving of the weldings and sandblasting and painting
-The reducer has attacks for hoisting, inspection covers and plugs of air breather
-Rolling bearings of first international mark (SKF-FAG-TIMKEN) calculated for a duration L10>100.000 hours
-The bearings assembled on the intermediate axis are housed in eccentric bushes that permit to optimize the toothings contact
-All supports of bearings have thermocouples Pt100 to take the temperature.
-Slow shaft in alloy steel hardened and tempered

.The lubrication of all gears and bearings is “forced” by central of lubrication assembled on plate, composed of:
-Nr. 2 motorpumps at gears, one in stand by to the other
-Duplex filter in delivery with electrical gauge for the control of stoppage degree
-Heat exchanger water/oil with automatic thermostatic valve for the regulation of water flow in function of oil temperature
-Visual thermometers entry/exit of the exchanger to verify the heat exchange
-Visual manometers
-Visual thermometers
-Flow indicator for the control of oil passage with electric contacts
-Pressure switch for the control of the minimum pressure
-Overpressure valve
-Thermocouple Pt100 for the control of oil temperture.
-Internal and external pipes with sprayers that guarantee the suitable introduction of oil at all bearings and at rotation organs.
