Föttinger原则
两个相对的，径向叶片叶轮容纳在泄漏 -
证明住房。叶轮没有机械连接到
each other. Because of the axially parallel arranged blades, the
扭矩独立于旋转方向传输
并且仅通过油灌装。
Hydrodynamic couplings have the characteristic properties of
流体流动发动机。可传递扭矩取决于
density and quantity of the operating fluid and increases as the
square of the drive speed and the fifth power of the profile diam-

pump and turbine impellers. A centrifugal force pressure field is
set up that is greater in the faster rotating pump impeller than in
the turbine impeller. The difference in speed, usually termed
“slip”, at the continuous operating point of the coupling is be-

Depending on the FLUDEX coupling series, drive is via the inner

通过叶片外壳叶轮（刀片轮壳体）。驱动 -

A low-viscosity mineral oil VG 22/VG 32, which also serves to lu-
bricate the bearings, is used as fluid. In special types water, a
水乳液或低可燃性流体可以用作非

不同填充水平FG的滑动扭矩特性
扭矩特性取决于油填充量FG
在耦合中。这使得可在启动时启动变速

Conversely, with a lower filling level the starting torque de-
