Parallel-shaft gear-motor CFM series

single-phasethree-phasegear train

The modern design with which these speed reducers, spur gears, parallel or orthogonal gears geared motors have been developed and the technology employed in their manufacture, the quality of the materials used together with the certified ISO-9001 standard quality assurance system lend this series a high degree of reliability that ensures its integration and adaptation to the medium. This series of universally fitting speed reducers comprises 5 types for different drive ratios with two or three reduction stages, in accordance with the desired gear ratio. Characteristitics This modular gear reducer has been designed for universal attachment systems, since the housing is fitted with a base plateon both the top and bottom and is designed for attachment with B-14 flange on both sides, with a centering shoulder to couple B-5 flnges on both sides. 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.
