The connection between an electric motor and a work machine shaft is achieved through a flanged rigid coupling where the torque is transmitted via coupling flanges. The power and rotational speed of the electric motor are determined using the last two digits of the student numbers, according to the formulas provided below. The coupling flanges are connected with three bolts of grade 5.6 with a 40 mm pitch circle diameter. The surface pressure endurance limit for the bolts is 16 MPa. The contact length between the bolt and the coupling flange is 12 mm. The coefficient of friction on the flange surfaces is 0.14, and the operating factor for the coupling is 0.8. The working conditions and material properties of the contact element are well-known, allowing for accurate force and stress analysis. (NO=35) a) Determine the bolt to be used in the coupling from the table. b) Draw the full sectional view of the used coupling. Power (N): N = NO [kW] Speed (n): n = NOx12 + 450 [rpm]
