Difference Between a Rotational Damper and a Linear Damper
A rotational damper and a linear damper share a common feature in that they both use hydraulic pressure and generate shock absorbing capacity by oil flowing in a narrow channel. However, the difference lies in the method of obtaining shock absorbing capacity: a rotational damper achieves this by rotating a shaft, while a linear damper achieves it through linear motion. A rotational damper is a component that slowly closes a toilet lid, for example, by generating torque through the viscous resistance of oil or hydraulic pressure produced by rotating the internal mechanism. There are two types of rotary dampers with different structures. One is a continuous rotation damper that obtains shear resistance by stirring a viscous body while maintaining a certain space, and the other is a partial rotation angle damper that obtains high hydraulic pressure by intentionally pouring a viscous body into a narrow area. On the other hand, a linear damper is a mechanical component that slowly closes
