EXPLAIN DESIGN CALCULATIONS FOR A SINGLE PLATE DRY CLUTCH – COURSE QUESTION
The question requires the student to calculate the required size of a plate clutch, and the suitable axial force in that case, to be used in an engine of a given torque while the plates have a given limited pressure.
A single-disk dry clutch (Similar to Fig 18.2), is to be designed for use with an engine with a maximum torque of 350 N m. A friction material is to be used for which design values are f = 0.25 and pmax = 350 kPa. A safety factor of 1.4 should be used with respect to slippage at full engine torque, and the outside diameter should be as small as possible. Determine appropriate values of r1, r2 , and F.
