In case of a multiple disc clutch, if n 1 , are the number of discs on the driving shaft and n 2 are the number of the discs on the driven shaft, then the number of pairs of contact surfaces will be:
n 1 + n2 - 1
The driving and driven discs are arranged alternately. A stack of \(n_1+n_2\) discs has one fewer adjacent contact interfaces, so the number of active friction pairs is \(n_1+n_2-1\).
Important Questions from Friction Clutches
Which of the following statement is CORRECT about the dry clutch?
- In a multiple disc clutch, if there are 4 discs on the driving shaft and 3 discs on the driven shaft, then the number of pairs of contact surfaces will be equal to _______.
In designing a plate clutch, assumption of uniform wear conditions is made because:
A single plate clutch has outer and inner radii 50 mm and 20 mm respectively. An axial clamping force required to engage the clutch is 2 kN and coefficient of friction between liner material is 0.4, the torque carrying capacity of the clutch using uniform wear theory is
