LR - AUTOMATIC TORQUE LIMITER WITH OVERRUNNING CLUTCH
21
This device interrupts the transmission of power when the torque exceeds
the setting. To automatically re-engage the device, slow down or stop the PTO.
This device prevents transmission of inertial loads from implement to the tractor
during deceleration or stopping of the PTO.
This device is sealed - no additional lubrication is required.
GE – SHOCK ABSORBING CLUTCH
22
Absorbs shock loads and vibrations, and smooths transmission of an
alternating or pulsating load.
No maintenance is required.
FRICTION TORQUE LIMITERS
Check the condition of the friction linings when installing the clutch or after periods
of storage.
• If the edges of the clutch plates are exposed (see fig. 30) the clutch is either type
FV with Belleville spring or FFV with helicoil springs. Measure and record the spring
height as shown in figure 31. If the clutch plates are covered by a metal band (see
figure 32) the clutch is type FT. If the clutch discs are exposed and the bolts have
cap nuts, the clutch is of the FK type.
Following seasonal use, relieve the spring pressure and keep the clutch in a dry
place.
Check the condition of friction disks and restore spring pressure before using the
clutch.
If the clutch overheats due to frequent or prolonged slipping, consult your
equipment dealer or manufacturer, or your local Bondioli & Pavesi representative.
FV - FFV FRICTION TORQUE LIMITERS
23
The torque transmitted to the machine is limited by allowing the clutch plates
to slip relative to each other.
Torque peaks or short duration overloads are limited when the clutch is used and
adjusted properly.
It can be used as an overload clutch, or to help start implements with high inertial
loads.
The setting can be adjusted by modifying the working height of the springs.
The torque setting of friction torque limiters FV and FFV is adjusted by
24
increasing or decreasing the height "h" of the spring.
To increase / reduce the torque setting, screw / unscrew each of the eight nuts
by 1/4 of turn and check for proper operation. Repeat the procedure if necessary.
Avoid excessive tightening of the bolts - implement, tractor, or driveline damage
may occur.
FT - FK – FRICTION TORQUE LIMITERS
25
The torque transmitted to the machine is limited by allowing the clutch plates
to slip relative to each other.
Torque peaks or short duration overloads are limited when the clutch is used and
adjusted properly.
It can be used as an overload clutch, or to help start implements with high inertial
loads.
The FT has a metal band around its circumference.
The bolts should be tightened until the metal band around the circumference of
the clutch touches the spring. This condition can be obtained by tightening the
bolts until the spring locks the band and then unscrewing the nut by a 1/4 turn.
