DSF
-DSF/ EX Friction safety device
-Compact
and balanced edge - free group with precision coupling of the parts.
-Available in compact and simplified versions with some disks in stainless
steel material on request for humid environment.
|
| |
DSF/SI Intervention signalling model withautomatic
re-engage
-Overload
signal using an electrical-mechanical switch which acts as an appropriate
ring. -Immediate re-start of the system after the cause of overload
has been removed.
|
|
DSF/TF/AP Friction safety device pneumatic drive
model
-Maintenance free
up to the complete wear of friction rings. -Tension function by the constant
monitoring of the load force.
|
|
DSF/EX/TAC/PR-V Model with axial chain transmission
(assemblage on the fast shaft between motor and reducer).
-Assemblage between
motor and reducer; smaller limiter for the same torque transmitted. -Operational
aluminium spacer to house the limiter, with an inspection door to be used
also for torque adjustment.
|
 |
DSS
- Balls safety device
-Top
sensitivity and accuracy in calibration and keeping of the disengagment
torque. -Also available with round and square section coil springs for
improved calibration accuracy and decreased residual torque ..../CM
(minimum torque).
|
 |
DSR/F
Timing rollers safety device
-Stable
transmission also in the presence of vibrations or small torque changes
with re-engagement every 360 degrees. -Different torque in the two directions
of rotation (model DSR/F/SMO); timing kept also in transmissions with
ratio other than 1 (model DSR/F/AM).
|
 |
DSR/F/RF
Timing rollers safety device free rotation
-Free
rotation after the overload induced disengagement till the inertial forces
go down to zero. -Simple manual re-engagement by the operators intervention
on the relevant conical ring.
|
 |
DSR/F/PI
Phase advancer model for intermittent drive unit
-
Dimensions and characteristics (torque, keying, disengagement rotations)
suitable to various models of intermittent drive units available in the
market. -Transmission of alternate backlash-free motion by conical ring
locking assemblies.
|
 |
DSR/F/AP
Timing roller safety device, pneumatic operated timing
Can
be used as a torque limiter and/or for transmission engagement-disengagement;
it can be controlled also through PLC by a proportional valve. -Torque
variation through pressure adjuster, also when the machine is moving.
|
 |
DSA/DTC
Axial safety device, for the disengagement of compression traction
-Total
protection from linear overload (both in thrust and in traction), with
equal or different force calibration (up to 7000N) in the two directions
with automatic re-engagement.
- - Possible (axial or radical) assemblage of either an inductive proximity
sensor or a stop electromechanical micro-switch.
