Question details

For the shown shaft-bearings assembly in the figure below The shaft speed is 300 revolutions per minute and a design life of 30000 hours is desired. Using an application factor of 1.2 and a combined reliability of at least 0.92 1. 2. 3. Determine the reactions at A & B bearing locations (Consider, the axial load is taken by bearing B as shown in the figure). (2 points) Select from Table 11-3 appropriate cylindrical roller 02-series bearing for location A. (Spoints) The following angular contact ball bearing has been selected from Table 11-2 for location B: Bore Diameter-25 mm, C10- 14.8 KN and Co 7.65 KN Show this is NOT a right selection and select another appropriate angular contact ball bearing. (10 points In light of your selection for the bearings at A and B, suggest what is needed to reduce the shaft manufacturing time 4. points) Ay Raz 845 N RB 536 N 1210 N 146 mm 20.0 1068N RBz 146 mm 73 mm
