A spur gear C transmits power to a V-belt pulley A via a shaft ABCD rotating at 2000 rev/min and transfer power with a moderate shock (take the lowest value). The shaft is supported by two bearings, i.e. one bearing at B and one bearing at D as shown in Figure Q1. The belt tensions are F1 = 450 N and F2 = 200 N. The gear forces are F3 = 1200 N, Fs = 700 N. The system will last until 25,000 hrs and both bearings has 98% reliability PO1 10 marks PO2 16marks i compute the total radial loads acting at bearing B and bearing Drespectively. ii. If the total radial reaction forces at the bearing B is 950 N and at bearing D is 850 N, and bearing D is also designed to support the thrust load of Fs = 580 N, determine all the suitable sizes of the roller bearing and angular ball bearing for the shaft problem ii. Design the suitable size of Bore, OD, w,r,ds, and du for shaft and housing at bearing B and bearing D (refer Figure Q1).
