CHM (Motorvario) and CHB (Bonfiglioli) gearboxes from Transdev provide industry standard interchangeability
Following last year's distribution agreement with Chiaravalli Trasmissioni, Transdev is now able to offer form-fit equivalents of Motorvario and Bonfiglioli worm gearboxes and geared motors at competitive prices.
The CHM (Motorvario) and CHB (Bonfiglioli) series provide industry standard interchangeability covering a comprehensive range of aluminium and cast iron CNC machined housings with RAL 9022 powder coated epoxy protective finish.
With power ratings from 90W to 7.5kW, they are available in a wide choice of foot, flange and face mounting options with selectable motor position, single or double shafts, connection flanges for multiple mounting and a range of accessories including pre-stage gear reducers and torque arms.
The CHM range covers nine models with ratios from 7.5:1 to 100:1 and single or double solid input shafts on 25 to 130mm centre distances.
Nominal torque ratings are up to 14nm for the smallest frame model unit and are up to 650nm for the largest.
The CHB range covers four models with ratios from 7:1 to 100:1 with centre distances from 30 to 62.17mm with torque ratings to 110nm.
The modular design of both CHM and CHB versions includes standard B5 and B14 flanges with mounting surfaces on all faces allowing a wide choice of flange and foot mounting positions.
Specifications, installation and operational instructions are detailed in separate catalogues, available in hard copy or as a PDF on Transdev's website.
For use with the gearboxes, Transdev also supply a range of four-pole, three-phase motors with continuous service ratings to IEC 34-1, closed design IP55 housings and Eff2 efficiency levels.
With both B5 and B14 flanges and IEC power ratings to 7.5kW, accessories include forced ventilation kits.
Two-pole and six-pole windings and higher efficiency versions are also available.
