Concept explainers

Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.

The axial pressure on a single disc clutch (both sides of the disc is effective) is limited to 0.12 Mpa. This is designed for a vehicle with 13kW power at a speed of 700 rpm. Assume uniform wear conditions and a friction coefficient of 0.25. If the outer dimater of the disc is 1.25 times the internal diameter, determine the dimensions of the disc lining and the axial force exerted by the springs.
8. A cross belt arrangement has centre distance between pulleys as 1.5 m. The diameter of bigger and smaller pulleys are 'D' and 'd' respectively. The smaller pulley rotates at 1000 r.p.m. and the bigger pulley at 500 r.p.m. The flat belt is 6 mm thick and transmits 7.5 kW power at belt speed of 13 m/s approximately. The coefficient of belt friction is 0.3 and the density of belt material is 950 kg/m³. If the permissible tensile stress for the belt material is 1.75 MPa, calculate: 1. Diameters of pulleys; 2. Length and width of belt. [Ans. 500 mm, 250 mm ; 4.272 m, 90 mm]
