Elastic coupling “G”
The introduction of flexible coupling “G type” as replacement of traditional shaft/key fitting between motor and gearbox, gives various
advantages but keeping unchanged gearbox overall dimensions.
Advantages
• One gearbox only for each ratio
• Greater flexibility
• Increased stock rotation
• Fretting corrosion elimination
• Coupling zero backlash
• Angular misalignment 1deg. max.
• Torsional rigidity
• Vibration damping

To the scope of intensifying our commitment to society, Varvel
since 2004 started an ongoing support programme with three
non-profit institutions: UNICEF (United Nations Children’s Fund),
MSF (Médicins sans Frontères) and ANT (National Cancer
Association). Environmental respect and protection are also part
of Varvel’s values and this is why Varvel certified in 2001 its
Environmental System to standard UNI EN ISO 14001.
