2562SVTL12.1
• Voith geared variable-speed couplings combine mechanical gears and a hydrodynamic variable- speed turbo coupling in one common housing
• The oil tank is bolted to the bottom of the housing
• The gear stage is arranged on the input side of the coupling.
Design and OperationGeared Variable Speed Coupling - Type R1.K
3562SVTL12.1
• Both working and lube oil are supplied from the integrated oil tank, but have separate circuits
• The oil system can also be used to supply both the motor and the driven machine with lube oil
