Calculation of Number of Discs Required in a Multiple-Disc Clutch
Given Data:
- Power transmitted (P) = 50 kW
- Speed (N) = 1400 rpm
- Axial intensity of pressure (p) = 0.12 N/mm2
- Coefficient of friction (μ) = 0.12
- Inner radius of discs (r1) = 80 mm
- Outer radius of discs (r2) = 1.4 * r1 = 112 mm
Formula Used:
- Power transmitted (P) = 2 * π * N * T / 60
- Axial force (F) = π * (r22 - r12) * p
- Torque (T) = F * μ * rm
- Number of discs (n) = (P * 60) / (2 * π * N * T)
Calculation:
- From the given data, r1 = 80 mm and r2 = 112 mm
- Mean radius (rm) = (r1 + r2) / 2 = 96 mm
- Speed (N) is given in rpm, so it needs to be converted to rad/s
- N = 1400 rpm = (1400 / 60) rad/s = 23.33 rad/s
- Axial force (F) = π * (r22 - r12) * p = π * (1122 - 802) * 0.12 = 2755.2 N
- Torque (T) = F * μ * rm = 2755.2 * 0.12 * 96 = 31623.552 N-mm
- Number of discs (n) = (P * 60) / (2 * π * N * T) = (50 * 60) / (2 * π * 23.33 * 31623.552) = 2.35
Answer:
Therefore, the number of discs required in the multiple-disc clutch is 3 (since the number of discs needs to be a whole number). This means that the clutch will have 3 pairs of friction surfaces, with each pair consisting of an inner and outer disc.
