Multiple-disc torque limiter Type 581

Product catalog summary
Characteristics and Features
  • Negligible wear due to special friction lining.
  • Frictional torque transmission with variable transmitted torque between 80% and 110% of the rated torque.
  • Smaller torques available upon request.
  • Torque is maintained during overload; quick input drive shutdown is recommended to prevent thermal damage.
  • Suitable for oil or dry running.
Applications and Customization

Mönninghoff's multiple-disc torque limiters are versatile, designed for extreme conditions, and applicable in various fields such as medical robotics, aerospace, and packaging industries. Custom solutions are available for specific torque, engagement behavior, and rotation speed requirements.

Selection Criteria
  • Overload torque should be at least 20% larger than average torque.
  • Consider peak load and dynamic behavior for correct size selection.
  • Torque selection formula: TK = (Ta + TL) x K [Nm].
  • Heat potential must be less than the actual energy absorbed: Ep < EK x K1 x K2.
Technical Specifications

Includes detailed dimensions, torque capacities, and weight for different sizes (11, 13, 21, 22, 24, 26). Bore sizes and keyway dimensions are specified according to DIN standards.

Design Variants
  • Design 1.1: Standard design.
  • Design 1.3: With sliding bearing.
  • Design 1.4: For connecting two shaft ends.

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 clutches...

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]
