Question

The following data relate to a single plate friction clutch whose both sides are effective: Power transmitted = 35 kW Speed = 1000 r.p.m. Permissible uniform pressure on lining material = 0.07 N/mm2 Outer radius/Inner radius of plate = 1.5 Coefficient of friction of lining material = 0.3 Number of springs = 6 Spring index = 6 Stress concentration factor in spring = 4C - 1/4C - 4 + 0.615/C, C = Spring index Permissible stress in spring steel = 420 MPa Modulus of rigidity of spring steel = 84 kN/mm2 Compression of spring to keep it engaged = 12.5 mm Design and give a sketch of any one of the springs in the uncompressed position. The springs are round section close coiled helical type and are situated at mean radius of the plate. [Ans. d = 5.65 mm; D = 33.9 mm;n = 6]

Explanation / Answer

We have power transmitted =35kw speed =1000rpm permissible uniform pressure =0.07N/mm2 also we have Rout/Rin =1.5 compression of spring =12.5mm stres =420Mpa this give Rout =33.9mm Rin=5.65m so we have the ratio rout/Rin=6
