n P ) expressed in kilowatts (kW) and the output rotation speed of the gearbox ( Orthobloc 3000 geared motors withhelical bevel gears are used to adapt the speed of the electric motor to that of the driven machine. Their size is therefore determined by the motor power ( Rated output torque: up to 3,150 N.m. Power ratings: from 0.25 to 22 kW.Reduction ratios: 10 to 160 Three reduction stages. High ef�ciency: 95%. Reversible. Quiet operation.

Orthobloc (Ot) gearbox:

Component Materials Remarks S , SBT or with flanges BS , BD …, BR . They are compact and meet industrial requirements Frame Cast iron - use of ENGJL cast iron (flake graphite: 200 MPa tensile strength) single component perlite to ensure unit is fully sealed - monobloc ribbed with internal reinforcements to absorb vibrations and noise, and increase its rigidity - foot mounted Gears Steel - cut by the gear hob, they are heat treated and then undergo final machining.The quality and precision of the gear cutting allow maximum torque with minimum noise level Shaft Steel - grinding of sealing surfaces - hollow or cylindrical output with key in accordance with ISO R 773, or hollow with SD shrink disc- tolerance of diameters in accordance with NFE 22-051 and ISO R775- tapped holes at the solid shaft end for fixing connecting devices in accordance with DIN 332 version D Lipseals Nitrile - sealing rings between housing and flange- antidust lipseals in accordance with DIN 3760 form AS- gasket under the access cover End shield Cast iron - reinforced by large ribs, this ensures ruggedness of the gearbox under heavy loads Lubrication Oil - in accordance with ISO 6743/6- delivered with the quantity of oil corresponding to the operating position, it is fitted with drain, level and breather plugs Mounting AP: input shaft gearbox MI: geared motor with integrated motor MU-FF: geared motor with IEC motor, manufactured with universal mounting Standard motor LS: multi-voltage 220/380 V - 230/400 V - 240/415 V - pressed steel fan cover, on request fitted with a drip cover for operation in vertical position shaft facing down) - metal terminal box fitted with cable gland - IP 55 standard protection Brake motors FCR: failsafe brake induction motor, from 0.25 to 15 kW, IP 55 protection FCPL: failsafe brake induction motor, 18.5 and 22 kW, IP 44 protection Finish Paint Shade: RAL 6000 (green), system I (1 polyurethane vinyl layer of 25/30 µm)
