Clutches and Brakes Sizing and Selection The sizing of a Warner Electric clutch or brake depends on various factors. The most common of these factors are shown below in chronological order: • Transmissible torque: In Nm • Energy source: Electric, Pneumatic, Hydraulic, or Mechanical • Actuation mode: Static or Rotating • Operational environment: Oil, Dry or Mixed • Heat dissipation: Duty Cycle, Inertia, Speed, etc. • Orientation of mounting: Horizontal, Vertical, Inclined The majority of applications can be computed using the formulas and calculation methods given below. For special cases we...

Clutches and Brakes Size and Selection Total Inertia This is the sum of all rotational and reflected inertia's (including the inertia of the clutch or brake parts). 3) Time to accelerate or decelerate Md = ( Jtotal · n ) / ( 9,55 · t ) where: Md = Jtotal = n = t = acceleration/deceleration torque in Nm total inertia in kgm2 speed of clutch or brake shaft in min-1 acceleration / deceleration time required in s under no condition can they withstand loads higher than specified in their data tables. (contrary to a friction clutch, the tooth clutch can never slip). Therefore one must know: • The...

Clutches and Brakes Sizing and Selection – Ml = static torque for clutch in Nm + Ml = static torque for brake in Nm n = clutch or brake speed in min-1 For vertical motion from top to bottom + and – are reversed Torque limiter W = Md · n · t / 9,55 where: W = in Joules Md = slip torque in Nm n = speed in min-1 t = slipping time in seconds air chamber. To avoid pressure losses in axial supplies the use of an air tight connection between the hub and the shaft is recommended. For radial supplies, a flexible connection without constraints is recommended. Hydraulic - The normal service pressure...
