Friction ring sliding
DSF/SI
DSF/SI
Intervention signaling clutch safety device
Torque limiter safety device with friction discs are particularly suitable for machines which produce dust or
dirt: wood processing and agricultural machines, earthworking
machinery, packing machines, coveyor belts, texile machines, charging devices for chemical industry
equipment, and generally in cases when maintenance of the timing between the two shafts is not
necessary.
TRANSMISSIBLE TORQUE from 1 to 25.000 Nm
DSF/TAC
Clutch safety device chain axial transmission
Caratteristiche tecniche:
Survey of the overload through electronic switch for machinery arrest. Connection of two coaxial shafts with absorption of angular, axial and radial
skews.
DSF/TF/AP
Friction safety device tension servoamplifiers ng, brake pneumatic operate.
Main specification differences compared to traditional friction devices are:
maintenance free until friction rings wear out;
constant torque maintained since the force remains constant as a result of wtroke self compensation in accordance with wear;
simple adjustment through pressure regulation;
torque adjustment whilst machine is running.
DSF/EX/.../PR-V
New system for protection against overload for worm reduction units.
Possibility for assembly of the limit device, going out on the slow shaft of the reducer (DSF/EX/TAC/PR for coaxial shafts) and (DSF/EX/PR for parallel shafts), or coming in between the engine and the reduction unit (DSF/EX/TAC/PR-V), where there are problems of space, very high outgoing torque, or other.

Rolling with balls and rollers
DSR/SMO
Version with a one-way direction (SMO) available with clockwise and anticlockwise rotation. These version have a calibrated torque in one direction of rotation and an higher torque in the opposite direction which is useful in situations when heavy masses or forces of inertia can exceed the preset
calibration.
Technical features:
Ratio between two directions up to 1/1,5 and on request up to locking version
DSR/F/AM/MDF
Clockwise and anticlockwise, timing roller torque limiter mechanical stop with timing holding, reaches this aim to keep the timing between two parallel shafts with transmission ratio different between
their.
DSR/F/AP
Timing rollers safety device with pneumatic driving: possibility of changing the transmissible torque also during
running, in order to counteract take-offs, possibility of adjusting torque during operation by simply adjusting
pressure, for a better flexibility in the use of automatic
machines.
DSA/DTC
Axial safety device
This device (italian and european OMC patent no. EP 574365) is able to protect linear overloads
(thrust and tensile) with equal forces in both directions and, upon
request, also with differential forces based on specific
requirements.
EDF/DSS
Friction torque limiter development balls safety device
The principle behind this device is the answer to the challenge launched by the market for an innovation that could resolve problems
(presence of oil, humidity and chemical agents) connected with the use of friction torque
limiters.
