General Information - Safety Warnings - Product Layout General Information Varvel speed reducers and variators are not in the field of application of the Machinery Directive 2006/42/CE as considered “machinery components”. Guide of Machinery Directive - § 35 - decrees: "The Machinery Directive does not apply directly to machinery components, such as, for example, valves, hydraulic cylinders or gearboxes, that do not have a specific application as such but are intended to be incorporated into machinery, although the design and construction of such components must enable the complete...

Coupling “G” The flexible coupling “G” is supplied on the Series RD, RN, RO, RV, RP, RS, RT as standard input equipment. The bore version with keyway is supplied on demand. (A) - Gearbox half-coupling (B) - Spider (C) - Motor half-coupling Advantages  Friction clamped coupling on motor shaft  IEC/NEMA adapters and couplings fitted on already assembled gearbox  Elimination of fretting corrosion between bore and key  Zero backlash in gearbox/motor connection  Angular allowed misalignment lower than 1°  High torsional rigidity A Mt - Screw locking torque Mt1 - Transmissible torque with...
