Simple and economic friction torque limiter. Suitable for dusty conditions without need of timing between gearbox and output. Silent overload without vibration. Protection in both rotation directions. Asbestos-free friction discs. Simple and precise torque seffing by adjusting the locking ring. Innovative calibration system by "H dimension" for an immediate calibration of the device. REQUEST Complete with transmission gear, fully turned and mounted (plate wheel, pulley, gear pair). Different types of friction discs for specific applications. Possibility of connections with bore and keyway,...

Simple and compact solution. Version with coil springs for fine adjustment: .../CM. Available in corrosion resistant: DF/EA. Available with customized alignments ("L") interchangeable with other models on the market. Available with radial ring statically balanced: .../GR. Torque range from 1 to 23.000 Nm; max. bore 0140 mm. • P *: On the size 00.25 the grubscrew is located on the nut side, not on the flange side. • Weights are relevant to the torque limiter with pilot bore (DF), inertias refer to the maximum diameter for finished bore.

Electromechanical overload signaling. Automatic re-engaging after transmission reset. Assembly with helical springs possible: .../SI/CM. Available with a longer shaft for assembly with transmission elements of large size: ./SI/ML. Available with friction rings with different performances for specific needs. Torque range: 3 - 23.000 Nm; max. bore: 0140 mm. (long-hub version) (long-hub version) • Weights are relevant to the torque limiter with pilot bore (DF/SI), inertias refer to the torque limiter (DF) hole max. • Microswitches EM1 or EM2 and inductive sensor PRX see page 73

Simple and compact solution for transmission with in-line shafts. Protection in both rotation directions. Possibility of different types of friction discs for specific applications.

DF - friction torque limiter: additional informationOTHER COUPLING ON REQUEST ■ Model DF suitable for connections GF to coaxial shafts capable of recovering high misalignments. Helical springs execution, for a wider torque range and consequently a finer adjustment on calibration is possible. .../EA: rust resistant Rust resistant execution, with stainless steel rings, galvanized for application in wet environments. .../GR: model with radial ring Ring with radial locking statically balanced alternative to the grooved nut GT standard. Available from size 00.38 to 5.170. GT/DR KIT: kit for...

DF - friction torque limiter: additional information ■ PLATE WHEELS The driving part selected (plate wheels, pulleys, gears, and so on) to be incorporated into the friction torque limiter, must adhere to predetermined characteristics (ex. the surface in contact to the friction rings with roughness Ra=0,8 : 1,6) to ensure good performance.^ the table below, there are standard plate wheels in ComInTec's production (supplied already grounded) which can be assembled on the torque limiter; and the minimum chain passage"V"(see picture 3), necessary for the correct sizing of the plate wheel to...

DF - fric on torque limiter: addi onal informa on SENSOR CONNECTION EXAMPLE To maximize the life me of the fric on rings and maintain the performance of the limiter, you should promptly stop the drive as soon as the first slip occurs. This is possible using the model DF / SI combined with a micro-switch (model EM1 or EM2) or an induc ve sensor (model PRX), see page 73. If this is not possible, however, we suggest the use of an induc ve sensor connected to a tachometer or frequency inverter in order to reveal the possible speed change of a metallic mass connected to the organ of transmission,...
