Low backlash planetary gearbox VARVEL

VARVEL low-backlash planetary speed reducers, Series RG, are designed for two and three stages, with hardened and tempered steel housing and broached internal gear. Manufactured to latest ISO engineering design specifications the housing is checked by computer-aided structural analysis for deflection and stress distribution.

The planetary speed reducers RG are made with gears of carburized alloyed steel, hardened and tempered; the planetary gear shafts of hardened and tempered steel; the input and output flanges of drawn aluminium (a micro version is manufactured without the output flange).

The universal motor coupling is available by the means of a clutch fitting and input flange and bush adapters.

The series RG is made in 4 sizes (RG050 - RG070 - RG090 - RG120), one and two stages, reduction ratios 3/1 to 100/1 and nominal output torque 12Nm to 220Nm.

The planetary gearboxes Series RG give a remarkable precision (angular backlash lower or equal than 8 minutes of arc for one stage and lower or equal than 12 minutes of arc for two stages) and quietness (lower than 70 dB-A for the sizes RG050, 070 and 090, and lower than 75 dB-A for the size RG120).
