Which statement is generally correct about an oil-cooled wet clutch compared with a dry clutch of equal size, clamping force and number of friction interfaces?
Heat dissipation is easier on the wet clutch as compared to the dry clutch.
In an oil-cooled wet clutch, circulating oil carries heat away from the friction surfaces, improving heat removal. Oil generally lowers the friction coefficient, so higher torque capacity is not an inherent advantage for equal size, clamping force and interface count. A wet clutch operates with oil at the friction surfaces.
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
