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 avoid...

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, as...
