helical gear reducer / coaxial / for shafts / high-precision

The Robus, manufactured by Motive, uses optimum power steels such as 15CrMo4 and case hardening to 58 ?2 HRC, in order to reduce the wear rate in wheels. All wheels are profile-ground according to Din 3962 class 6 accuracy for minimized noise and high efficiency rates.

The shafts of the unit are built from 42CrMo4-grade Steel materials, and are tempered to achieve a hardness of 23-35 HRC. These help in enhancing their capacity in resisting shearing stresses.

If the mechanical durability and the service factor of a helical gearbox are centrally affected by the centers distance of the last phase, Robus delivers comprehensive levels of durability. Single-stage ratios between 2 and 6, together with appropriate gears sizes, result mathematically in adequate teeth number and size (module) of every wheel, and a good fractioned load between the reduction stages.
