0 sez 300 1 200 Fig. 3.9(b) 3.10 The sketch shows a muff coupling and a cone clutch on a short shaft. Data given include speed 120 r/min; safe stress in shaft = 60 MPa; safe stress in muff coupling key = 62 MPa; safe stress in cone clutch key 62 MPa; axial thrust when clutch is engaged = 24 kN; safe bearing pressure (thrust collar) = 900 kPa; and mean diameter of the cone = 620 mm. The clutch operating lever is made of 2 M.S. flat bars (see sketch). Determine (a) the power transmitted; (b) the length of key in muff coupling (A); (c) the length of keys in cone clutch; (d) the outside diameter of the thrust collar; and (e) width and thickness of the lever, given that the width is 4 X thickness.
