OR ELECTROMAGNETIC COUPLINGS
MECHANICAL COUPLINGS SERIES 30100 - 30300 - 30500
They are unidirectional and bidirectional.
When coupling with hydraulic pumps we recommend to engage and disengage
the pump when the directional valve is in exhaust position at a
speed not over 1800 R.P.M.
In the reversible position the max engagement and disengagement
speed is 1000 R.P.M.
Oil type SAE 90.
Change oil every 12 months.
Max working temperature + 80°C
Mm working temperature —10°C
ELECTROMAGNETIC COUPLINGS SERIES 30900
Running-in is required to obtain the desired rated torque values
of electromagnetic couplings. Running-in is required to obtain
the desired rated torque values of electromagnetic couplings.
Running-in is carried out by engaging and disengaging clutch
at high speed several times with the pump in exhaust position.
During assembly, make sure that there are no oil or grease traces
on pulley surfaces whith must be completely clean.
When assembling electric clutches with front driving flange, check
for proper coupling alignment, but do not exceed rated torque because
this would cause slippage of contact surface. This stage must not
last more than 5 seconds since coils could burn.
