Vibratech TVD Component
Vibratech TVD Viscous Torsional Dampers
Viscous torsional dampers for crankshafts, camshafts, drivelines and electric drives, in which an inertia ring shears silicone fluid to turn torsional vibration into heat; made in the USA, ISO 9001:2015.
Description
Vibratech TVD viscous dampers control torsional vibration in rotating shafts, the twisting and rebounding caused by combustion forces, camshaft torque or start-stop of PTO and electric drives. Vibratech TVD (formerly Houdaille) invented the viscous torsional damper in 1946, originally for commercial diesel engines.
How it works
- An inertia ring inside a sealed housing shears through a thin layer of viscous silicone
- The silicone is not bonded and acts as a soft spring, converting vibration energy into heat
Types
- Crankshaft dampers – for durability of high-cylinder-pressure engines; large heavy-duty diesel dampers can be designed for remanufacturing
- Camshaft dampers – down to 3" outer diameter, hermetically sealed, with optional integrated flanges, gears or pulleys; maintenance-free
- Driveline dampers – tuned narrow-frequency dampers for PTO shafts, pump drives and similar
- Electric drive dampers – for hybrid and full-electric drivelines
Key features
- Higher durability than elastomer dampers
- Suited to high temperatures and harsh environments
- Manufactured in the USA; ISO 9001:2015 certified; ITAR registered
