FLUDEX FG and FV series couplings are designed for drive via<br />
the coupling housing. In the FV series (coupling with delay<br />
chamber), the motor drives the coupling housing, comprising a<br />
blade wheel (101) and a cover (102), via the flexible N-EUPEX<br />
coupling (part 2/3) and the delay chamber (115). The rotational<br />
flow of the coupling filling drives the blade wheel (105) and the<br />
hollow shaft (106) on the output side, which is mounted on the<br />
gear unit or driven machine shaft. In the FG series (basic coupling),<br />
there is no delay chamber, and the flexible coupling is<br />
directly flange-mounted on the blade wheel.<br />
When the coupling is started up, part of the oil filling is forced<br />
into the damming chamber. This enables the desired torque limitation<br />
(approx. twice T N ) to be achieved during starting. In the<br />
FV series the delay chamber also receives part of the oil filling in<br />
accordance with the fluid level when the coupling is stationary.<br />
During starting the effective oil filling in the working chamber is<br />

reduced by the amount of fluid in the delay chamber, thus considerably<br />
reducing the starting torque (approx. 1.5 times T N ).<br />
From the delay chamber located on the drive side, the oil is fed<br />
back time-dependently to the working chamber via small holes<br />
and the coupling torque is raised, even if the output is blocked.<br />
This replenishing function enables a drive to be soft-started with<br />
a very low starting torque and with an almost load-free motor. At<br />
the same time, however, increased load torques can be overcome<br />
by the torque increase in the coupling.<br />
The property of the coupling with delay chamber can be used<br />
advantageously, for example, to soft-start empty, partly loaded<br />
and fully loaded conveyor belts.<br />
FG series couplings are used for normal starting torque limitation,<br />
as a starting clutch for isolating vibration and for overload<br />
limitation in the event of drive blockage.<br />
