Question

Q- 3. The following features of a conical clutch are given: - Inside Diameter: 160 mm - Outside Diameter: 240 mm - Conical Angle: 18° - Friction Coefficient (f): 0.24 - The Torque to be transmitted (T): 240 N-m - Maximum Allowable Pressure (Pm): 2 bars Determine: a. Whether this clutch is suitable for that much torque transmission, b. If it is, the engagement force to activate the clutch.

Answer 1

#3 - 240 mm Conical clutch Given, Inside diameter (d) = 160mm = 0.16m =0.24 m outside diameter (D) Conical Coefficient of friction, f = 0.24. Torque to be transmitted (+)=240N-m. Allowable pressure (Pmax) = 2 bar = 2x10 pa angle = 180 theory is d t go 2 Allowable torque Capacity as per uniform wear given by, . M 7. fo Pmax.d *(D2-43) 8 sina x = semi-Cone angle 18% Mt. ** 0.24 * 2X10* 0.16 * (0.242 0.163) 8 * Singo I ME = 616.93 N-m. The actual torque transmitted is less than allowable torque Capacity. So, the given clutch is suitable 240 Nm of torque. so, So transmission of for (Ans--a)

T = f* W 3 b). For uniform wear th * (D+ d ) 4 Sina =) 240x3 = 0.24* W * (240+160) 4 * singo So, W 1564-34 N b) Ansa-b This is the engagement force to activate the Clutch.
