Multiple-disc torque limiter Type 581

Multiple-disc torque limiter - Type 581 Characteristics and features • negligible wear due to special friction lining • frictional torque transmission • transmitted torque is infinitely variable between 80 % and 110 % of the rated torque • on request smaller torques are possible • transmitted torque is maintained when overload occurs • to avoid thermal damage, the input drive must be switched off as quickly as possible by means of slip or zero speed detectors • oil or dry running Mönninghoff power transmission represents an infinite variant diversity that is applied by all areas of modern...

Multiple-disc torque limiter - Type 581 Match code Mönninghoff multiple-disc torque limiters are indicated by the following match code: 581 . A . B . C A coupling size B design C system Other individual characteristics: • bore size with keyway According to these characteristics, we design individual solutions concerning transmitted torque, engaging behavior or rotation speed. Our engineers can assist with finding an application-specific clutch at any time. Together, we can develop individual and innovative solutions for extreme operating conditions. Ordering example Mönninghoff multiplate...

Multiple-disc torque limiter - Type 581 Selection according to the torque When dimensioning a Mönninghoff multiple-disc torque limiter, several technical preconditions should be considered: • the overload torque should be at least 20 % larger than the average torque • for the selection of the correct size, not only the peak load but also the dynamic behavior of the drive have to be taken into account, especially for starting or slowing down • generally, the selection of the correct torque limiter is based on torque: TK = (Ta + TL) x K [Nm] Selection according to the heat-potential Friction...

Multiple-disc torque limiter - Type 581 Determination of the heat potential The real take up energy of the coupling depends on the sliding time per cycle in correlation to the cycle time and on the number of slides per hour. The correction factors for the real take up energy Ep of the coupling can be derived from the tables and graphs. tR / tZ Course of the slipping cycle tR = sliding time per cycle tZ = cycle-time ∆ω = differential angular velocity Correction factor k2 as function of number of slides Z / hour Heat potential Type 581 Size EK [Nm/h]
