Page 18: Disassembly And Exchange Of Wear Parts
Assembly 4.3 Disassembly and exchange of wear parts Disassembly and exchange of wear parts The friction linings of the torque limiter are subject to continuous wear, which requires occasional replacement of the linings depending on the tripping frequency. Procedure Loosen the clamping nut (3) by first bending up the locking plate (8) or loosening the locking screw (11), depending on the size. -
Page 19: Commissioning
Commissioning Slipping in of the friction linings Environmental influences such as surface roughness, material pairing, or even longer downtimes can have an impact on the accuracy of the set torque. Although these influences cannot be prevented but can be reduced by slipping in of the friction linings. If a higher accuracy of the limiting torque is required, it is recommended to let the torque limiter slip in at low speed for to 100 to 200 turns at approx. - Page 20 Commissioning 5.1 Slipping in of the friction linings Assembly and operating instructions 3950de Edition 05/2022...

Page 21: Operation
Operation Triggering the torque limiter SECUREX torque limiter are designed to absorb individual load peaks for protecting the system. Permanent slipping, especially for high relative speeds, leads to premature wear of the friction linings and should therefore be prevented. A slipping process with a duration > 1 second must be prevented in order to avoid an impermissibly high heating of the friction linings. - Page 22 Operation 6.1 Triggering the torque limiter Assembly and operating instructions 3950de Edition 05/2022...
