Power Transmitting Capacity of Multi-Disk Clutch
Given data:
- Number of steel plates (ns) = 5
- Number of bronze plates (nb) = 4
- Inner diameter of the friction disks (di) = 75 mm
- Outer diameter of the friction disks (do) = 150 mm
- Coefficient of friction (µ) = 0.1
- Intensity of pressure on friction lining (p) = 0.4 N/mm2
- Rotational speed (rpm) = [IRIS data]
Calculation:
Step 1: Calculating the effective radius (re) of each friction disk
The effective radius can be calculated using the formula:
re = (di + do) / 4
Substituting the given values, we get:
re = (75 + 150) / 4 = 225 / 4 = 56.25 mm
Step 2: Calculating the effective area (Ae) of each friction disk
The effective area can be calculated using the formula:
Ae = π * re2
Substituting the value of re and the value of π (pi) as 3.1416, we get:
Ae = 3.1416 * (56.25)2 = 3.1416 * 3164.06 = 9940.64 mm2
Step 3: Calculating the total effective area (At) of all the friction disks
The total effective area can be calculated by multiplying the effective area of each friction disk by the total number of disks:
At = (ns + nb) * Ae
Substituting the given values, we get:
At = (5 + 4) * 9940.64 = 9 * 9940.64 = 89465.76 mm2
Step 4: Calculating the power transmitting capacity (P) of the multi-disk clutch
The power transmitting capacity can be calculated using the formula:
P = At * p * µ * ω
Where:
- At is the total effective area of all the friction disks
- p is the intensity of pressure on the friction lining
- µ is the coefficient of friction
- ω is the angular velocity in rad/s
Since the rotational speed (rpm) is given, we need to convert it to angular velocity (ω) in rad/s using the formula:
ω = 2π * (rpm / 60)
Substituting the given values, we get:
ω = 2π * ([IR
Given data:
- Number of steel plates (ns) = 5
- Number of bronze plates (nb) = 4
- Inner diameter of the friction disks (di) = 75 mm
- Outer diameter of the friction disks (do) = 150 mm
- Coefficient of friction (µ) = 0.1
- Intensity of pressure on friction lining (p) = 0.4 N/mm2
- Rotational speed (rpm) = [IRIS data]
Calculation:
Step 1: Calculating the effective radius (re) of each friction disk
The effective radius can be calculated using the formula:
re = (di + do) / 4
Substituting the given values, we get:
re = (75 + 150) / 4 = 225 / 4 = 56.25 mm
Step 2: Calculating the effective area (Ae) of each friction disk
The effective area can be calculated using the formula:
Ae = π * re2
Substituting the value of re and the value of π (pi) as 3.1416, we get:
Ae = 3.1416 * (56.25)2 = 3.1416 * 3164.06 = 9940.64 mm2
Step 3: Calculating the total effective area (At) of all the friction disks
The total effective area can be calculated by multiplying the effective area of each friction disk by the total number of disks:
At = (ns + nb) * Ae
Substituting the given values, we get:
At = (5 + 4) * 9940.64 = 9 * 9940.64 = 89465.76 mm2
Step 4: Calculating the power transmitting capacity (P) of the multi-disk clutch
The power transmitting capacity can be calculated using the formula:
P = At * p * µ * ω
Where:
- At is the total effective area of all the friction disks
- p is the intensity of pressure on the friction lining
- µ is the coefficient of friction
- ω is the angular velocity in rad/s
Since the rotational speed (rpm) is given, we need to convert it to angular velocity (ω) in rad/s using the formula:
ω = 2π * (rpm / 60)
Substituting the given values, we get:
ω = 2π * ([IR
