1. Product History
1932: BHS in Sonthofen was the birthplace of the Stoeckicht planetary gearbox

2. Epicyclic Gear Units Stoeckicht load equalization
Efficiencies up to 99 %
Integrated couplings
Coaxial shaft arrangements
Compact design
Low weight

3. Epicyclic Principles
Planets and planet carrier are rotating the annulus is fixed (Voith BHS series RH...) to allow a very compact design mostly proposed for slow running applications. Directions of rotation for driver and driven sides are equal.
Planet carrier is fixed in the housing, the annulus is rotating (Voith BHS series RT...) to realise high speed applications. Direction of rotation for driver and driven sides are versus.
