High-torque gearmotor CRM series

DCthree-phasesingle-phase

The CRM serie geared engine reducers are characterized by the position of both coaxial input and output shafts and are made up of two or three helical gearsets. Their main particularity, is their great compactness and silence when working. The quality of the materials used together with the certified ISO-9001 standard quality assurances system, lend this series a high degree of reliability that ensures its integration and adaptation to the medium. Housing The gear reducer body and covers are made of highly resistant GG20 grey cast-iron, with ample proportions and deeply ribbed texture to withstand considerable stresses and vibrations. Gears The gears are made of casehardened alloy steel in accordance with IHA F154 and F156 for the gear pinions with a core breaking strain of 120 and 130 Kg/mm2 and F155 and F-158 for the gear wheels with a core breaking strain of 95 and 110 Kg/mm2. The surface hardness of both the pinions and wheels is 60/62 HRC and all the gears are flank ground with high precision machines. In the bevel gear or perpendicular shaft reducers, the spiral bevel gear is of the Gleason type. The pinion is made of F156 steel with a core breaking strain of 130 Kg/mm2 whilst the wheel is made in F158 steel with a core breaking strain of 110Kg/mm2, both types of steel being casehardened, quenched and lapped to prevent vibrations during running. Supports and output shafts All the shafts are made with IHA F155 alloy with a core braking strain of 95 Kg/mm2. Rotational speed: 1400-1500, 1650-1800, 7-300
