We will propose the optimal fluid coupling based on the starting characteristics of your rotating machinery!
We propose the optimal fluid coupling based on the technology and solid engineering capabilities cultivated from the experience of Voith. ◆ Applications Not only does it absorb the shock load from the driven side during the startup of large inertia machines, but it also absorbs the internal oil. ◆ Features As standard models, we offer fluid couplings with different delay chambers for each size: -T, -TV, -TVV, and -TVVS. This allows for a gentle startup without a sudden increase in torque, even for large inertia rotating machinery. ◆ Built-in Pulley Type We also have models with built-in pulleys, allowing for direct connection from the motor to the fluid coupling to the driven side without the need for installation of a plan block. This design eliminates the need for complicated alignment adjustments and saves space. ◆ Safety Device In addition to the standard fusible plug, a device for monitoring the temperature of the internal oil can also be added. This helps prevent blowouts caused by rising oil temperatures.
