    ☞Clutch & Brake Operation

    Selection



    Typical clutches and brakes are used for pressing and they have to be chosen considering these factors below.
  1. Torque of clutch.
  2. required torque for machine stopping.
  3. Heat generation rate during cycling.
  4. Dimension of shaft.
  5. The speed of crank shaft.
  6. Angle of crank at machine stopping.
    For choosing thin air clutch and brake, fundamental information below is needed.

    ☞Reference Data

  • Normal load ------------------------- 20ton
  • Starting crank angle ------------------- 90°
  • Distance from off button --------------- 0.00635m
  • 1/2 of Stroking distance --------------- 0.076m
  • Stroke ----------------------------- 0.15m
  • Shaft speed(RPM) of Clutch and brake ---- 204RPM
  • Crank angle at stopping --------------- 120°
  • Length air pressure ------------------- 0.9m
  • Required air pressure ----------------- 6kgf/㎠
  • Shaft dimension ---------------------- ø115

    Calculation for selection


    1. Torque Crank

    = RATED LOAD × 900Kg.㎡ / Ton × (Torque Arm)

    2. Torque Arm = y = (C) × (tan α)

    C = a + b - x

         = 0.076 + 0.9 - 0.00635

         = 0.97m

    Cos α =

         =

         = 0.9931

         = 1.8348°

    3. Torque Arm = y = (C) × (tan α)

         = 0.97 × (tan α)

         = 0.97 × 0.03224

         = 0.0313m

    4. Torque Crank = 200 × 900 × 0.0313

         = 5.634kgf.m

    • Required = T

         =

         =

         = 829kgf.m

  • Required torque is 829kgf.m and with safety ratio(k) 1.3, you will get 829 × 1.3 = 1077kgf.m. therefore, HACB-600 will be chosen.
  • 829 × 1.3 = 1077kgf.m
